Product Description:
Nothing ever published in the facility management field comes close to the unconditional acceptance of "The Facility Management Handbook". Extensively updated for the realities of today's workplace, the book gives readers the tools and guidance they need to wipe out inefficiency, and create a productive facility that integrates people, place, and process. In addition, the book includes 30 per cent new material, including indispensable information on sustainability and post 9/11 security concerns. Comprehensive and up to date, this is still the ultimate resource for facility managers.
Summary: Bible for FM
Rating: 5
I am a Certified Facility Manager (CFM) and an Interior Designer and have been in the industry for over 15 years working now as a consulant primarily focusing on strategic planning. This is recognized as the go-to reference for all that is Facilities Management (FM). I still, even with my experience, review sections and have referred this book to many peers and clients. Cotts will always be someone in our industry who brought FM to the forefront and makes everyone aware that it's not just "fixing toilets!" Recommended for anyone who is head of facilities management, planning, administration or real estate for both Government and private industry. Also, coming from the design community, this book should be on every planners shelf. The value chain cycle begins with concept, but many in the design industry forget that this includes construction, operations and maintenance, and lastly disposal.

Summary: Awesome. 10 stars.
Rating: 5
This book lays out the many concepts of all of the common devices, clearly. I have the signals book from this author as well, and both books are extremely impressive in my opinion. It's really hard to find good textbooks for school, and the "required" texts usualy stink, and are filled with explanations that are written to impress. This book is not like that at all, everything is clear and concise, tables and diagrams here and there sum up the past pages throughout the book. I'd give this book 10 stars if I could, when you buy this book you're also supporting a GOOD business, a business that's interested in making your process of "getting learnt" easier!

Inverter Use and Maintenance of Experience
Inverter Use and Maintenance of Experience
Inverter Use and Maintenance of Experience: We are on the maintenance of a large number of converters, it was found that many people in the converter during use, there are many issues to explore with you all here! A）！ A) Inverter for selected brands: Do not look the price, some inverter low price, but the quality, performance, very poor! ！ Its jerry-built, short life, accessories less difficult to repair, if the incumbent, the new circuit board is the maintenance costs would be astronomical; Some companies make a commitment for warranty service, but your inverter may be transported to thousands of miles outside the city, flowers one or two months time to fix, so to purchase converter about the neighborhood when the Department of whether the maintenance services; some converter Though this is the brand name, but it is finicky, there must be a good use of the environment (with air conditioning) makes a good quality; some components of transducer assembly more "exclusive special" hard to buy and the price high, so maintenance costs are also high; poor performance of the inverter Another problem is that when a fire is very serious, almost no maintenance of value; Inverter failure rate is relatively high, so When you purchase your convenience to understand their maintenance, inverter module is common, is it easy to buy; if a large amount of type inverter, it is best to buy more than one or two to reserve; If your inverter is used in a simple speed control, use relatively inexpensive price of the economic series, if the electrical load heavier, often emergency stop, please use a good performance, large capacity, or a converter! B）---) --- Do not mounted in a vibration transducer devices (such as injection molding machine, punching machine, washing machines), because it inside inverter main circuit connection screws easy to loose, there are many converters because of this reason that the damage! C）---C) --- Wiring Problem: The best converter input connected to an air switch, protect current can not be too large, in order to prevent a short circuit when the inverter will not be too severely burned! ！ Especially the most vulnerable of the older generation of electrical bills!！ The line of control Try not to be too long, since it made the control panel susceptible to electromagnetic interference generated misoperation! ！ Also lead to damage control panel！ Do not equipped with a high-current inverter next to the action of the contactor and often！ Because of its interference with frequency converter is very large, often make inverter malfunction (show all kinds of trouble)! Some people sake of convenience, always connected to start the Line of Control (such as the Mitsubishi STF-SD), a transmission frequency converter on the starter motor, so that inverter due to the current flowing through the charging resistor and easily burn charging too much resistance Ground should be well grounded, or severe electrical leakage, ground damage will be charged inverter. D) --- often have to urgently stop the inverter is best not to rely on inverter itself, the brakes, but as an additional brake resistor or a mechanical brake, or inverter motor back-EMF constant impact of the failure rate would be greatly enhanced! E) --- If the inverter current low-speed operation (<15hz),> F) --- dust and moisture are the most lethal killer inverter！ Especially when down a few days later, the dust stuck in the circuit board damp, when power transmission after the inverter circuit board on the most likely ignition damage！ Best to frequency converter is installed in air-conditioned room! 。 Or the installation of dust in a network taking into account the electrical cabinet.！ To regularly clean the circuit board and heat sink on the dust; down converter in power for some time before what is best to use hair dryer blowing circuit board! G）some brands converter when the cooling fan is broken, it will not be given over-temperature protection! Until the converter is damaged! So when the fan should be replaced with the sound! H) --- Some factory supply for generators, voltage instability, frequent damage to inverter Later, regulators or overvoltage protection devices to install generators with good results! I) --- mine is also very important! Although rare, but when the converter is mine to patronize, the heavy damage！ Inverter constant pressure water supply most likely to be struck by lightning, because it has an argument of mine water pipe extending toward the sky! J) --- Inverter interference is also a headache, it will make use of other electronic devices do not function, then inverter input, output, the line of control is best to use shielded cable, shield wiring methods should not be wrong, otherwise the opposite effect , it is possible to trap the re-use iron pipes, installing filters, lowering the carrier frequency! We found that if the inverter switching power supply switch is a FET (such as the K series), then its interference will be bigger! ！ ! K) --- When the inverter is broken beyond repair experience is best not to those who do not repair Otherwise, the more likely he or bad repair (often people call in deeply regret it) Sometimes fast fuse, and be sure to check the module if there are problems, and some are not experienced electrician, immediately loaded onto a good quick melt (absolute can not be used to replace copper wires), the result is a more powerful inverter burned, according to our experience, if the fast Most of the modules fuse problem, but the module is not necessarily a bad quickly melting off! Many inverter power module, rectifier module is to replace each other, and if we have to buy the original model, there may not buy or high prices!Maintenance of the modules had harmed a lot of people: We are in maintenance converter process, often encounter some factories blow up after his repair of the inverter, and the damage is more serious than the original, more difficult to repair! The inspection reveals that they too are using a maintenance module. Maintenance-off module is difficult to detect with the instruments, the argument completely normal, but because of its internal wiring rough, the transistor can not seal Grease opened sealed! This module can be used, some a few months, some one turn on the blow up Maintenance of the modules had to open then putting it back because it is so closely identified, or can be seen! Use of 502 glue stick to copper, Mo Shangqu rather hard! The original module's plastic smoother, soft!Maintenance-off inside the module due to the Qingdiao silicone grease, so that the module into a hollow, then beat his copper voice is different! It could also be damage to the module apart to see whether the rough wiring. Some pseudo-module is another label, from this model into another model! 把电流小的贴成电流大的！ The current is small, paste into an electric current big! Even paste into the low pressure of high pressure! Label printing technology is now more and more simulation, but as long as a careful comparison with the original look of the module, or can be seen in! ！ !
We repair a lot of elevator use inverter, found that many failures are because of their work environment through high temperature caused by aging components, easy, elevator converter installed in the building of the most top-level control room, often in the summer by the sun exposure, coupled with its own inverter and brake resistor heat, so that electric indoor temperature is very high, the work environment high temperature will shorten the life of electronic components! Converter in this respect more apparent, so when the elevator electrical room in the design of ventilation problems in addition must pay attention to insulation, such as the walls of hollow brick, multi-room roof design, if coupled with air-conditioning, then the president of a lot of the life of converter !！ Installation of electrical inverter cabinets in Xiamen days If you find that their internal temperature is very high, electric door should be open, I have seen many manufacturers of electrical cabinet design is too small Converter can be fitted exactly！ And do not install the cooling fan!
380V/220FU2（600V/1.5A） ------ Lift Inverter Maintenance Example: Today's maintenance of a lift 676GL5-15KW Yaskawa Inverter, initially due to fast melting 380V/220V transformer protection FU2 (600V/1.5A) blew (short-circuit cooling fan cause 380V/220V transformer short-circuit), district management office did not investigate the reason for electricians to use copper instead of FU2 fast melting, electricity board, after copper and around the ignition, Shao Rong copper spray to drive another board, resulting in two 2BI100NC-120 power module and driver board is damaged, 100A also blown melt faster, causing heavy losses.So please electrician note that under no circumstances can be used as a substitute for copper melting fast, otherwise, equipment damage is usually a very tragic and devastating!
Converter routine maintenance on the elevator: Now the lift is used to control the inverter, when the inverter failure would cause inconvenience to many people but also anxious bad management, if there are pairs of normal frequency devices for maintenance, you can greatly reduce the failure rate converter, we maintain a large number of lift inverter, the normal maintenance of summed up a few pay attention to the problem: 1) electric lift chamber temperature can not be too high, otherwise the converter components easily aging, the best air-conditioned, the effect is quite good! 2）2) to prevent rain water wet, usually in a typhoon when the windows and doors were blown into the rain shower bad Ershi converter. 3）Thunder and Lightning, which is linked to an entire building or an entire mine facilities of the district, was struck by lightning in general inverter and badly damaged. 4） Inverter cooling fan to clear dust from time to time and found that there is sound or not to run to be replaced. 5) The elevator motor, there were unusual sound transducer is usually a problem, such as the motor three-phase current imbalance, the best time is necessary to repair, until the converter is completely impossible may be more severely damaged. If he did not do their own maintenance on maintenance experience, many people have made more bad inverter.
- There is a lift maintenance company delivered a wide on the elevator to repair the Inverter Fuji VG5 he has been revised twice, and both spent a few days burning module, suffered heavy losses! Upon inspection, it is because when the thermal plastic latex with wheat in the module's bottom painted a result, burned by poor heat dissipation module. So if there is no experience, do not repair themselves, or may be wasted effort, money and time! Their maintenance has the following risk (often seen): If buy fake modules, drivers, faulty but did not find out, loading the wrong line, did not tighten the screws and so on! All these converters can be burned even worse!
—— 电梯厂家请注意：有的电梯厂家选用了安川制动单元，用了一段时间后发现经常坏制动管，后来经检查后发现是电压档选择问题造成的，安川制动单元要根据实际电 源电压选用电压档（有一短接片短接），分有380V、400V、415V、440V、460V电压档以适用不同国家。 - Elevator manufacturers Please note: Some elevator manufacturers selected Yaskawa braking unit, with a period of time after the discovery was often broken brake pipe, and later through the inspection found to be caused by voltage profile selection, Yaskawa braking unit should be based on the actual voltage power supply voltage selected file (with a short piece then shorted), divided into 380V, 400V, 415V, 440V, 460V voltage profile to apply to different countries. 在国内很多人都是选在380V档，但很多地区的实际电压都在400V以上，这样使制动单元的制动量大很多，制动管长期发热而寿命短，有的用几个月就坏掉，如果厂家一开始就选用400V档（或415V），当电源电压为380V也不影响电梯的使用！ Many of them are in the country chosen 380V files, but many parts of the actual voltages are 400V and above, so that the brake unit to brake much larger amount, the brake pipe and the short life of long-term fever, some with a bad few months out, if manufacturers start a file on the selection of 400V (or 415V), when the power supply voltage is 380V does not affect the use of the elevator!
------现在的假模块很多，下面是2MBI100NC-120模块真假对照图，左边是假的，假模块很难用仪表测出，如果你怀疑你的模块是假的可拆开看看，其接线很粗糙，工作寿命很短。 ------ Now a lot of false modules, the following is true or false 2MBI100NC-120 module control diagram, the left is fake, fake instrument modules are difficult to measure, if you suspect that your module is false can be apart to see of view, the wiring is very rough, working life is very short.
这是深圳一家电梯公司自己在街边购买模块维修变频器，结果把变频器炸到面目全非后才送到我们这里维修的，所以如果没有什么经验就不要自己维修变频器，否则有时会造成重大损害！ This is one of Shenzhen's own elevator maintenance in the street to buy the module inverter, inverter deep-fried to a completely different result that sent us after the repairs, so if there is no experience, do not repair their own converter, or sometimes cause significant damage to !
------三菱PM50RSA120二手模块(模块PM75CSA120、SP50Z6C、SP75Z6C也同样）现在很难找，也可用PM50RHA120代用，它们的最大差别在于前者的上半桥驱动脚是四条针一组，后者是三条针一组。 ------ Mitsubishi PM50RSA120 secondary module (module PM75CSA120, SP50Z6C, SP75Z6C also) is now difficult to find, can also be used PM50RHA120 alternative, their greatest difference is that the former is four feet on the half-bridge driving a group of needles, the latter is a group of three needles. PM50RSA120 四条针一组中第二条针是检测信号输出，与其下半桥驱动最后一个脚（19针）功能重复，很多变频器都没用到这条针的功能，所以用PM50RHA120模块上 半桥驱动的三条针插到PM50RSA120模块上半桥驱动的1、3、4针位置上就可以，当然针脚的位置要摆斜一下。 PM50RSA120 a group of four needles in the second pin is to test the signal output, the next half-bridge driver with the last one foot (19-pin) feature to repeat a lot of inverter no needles used in this function, so the module on the half-bridge driver with the PM50RHA120 The three-pin plug into PM50RSA120 half-bridge driver module on 1,3,4-pin position can, of course, the location of pins to be placed oblique look.
------- 如何学维修变频器:很多人打来电话询问如何学维修变频器,其实学维修变频器不算难,只要你有点电子知识,对变频器原理有点了解,很快可学会维修变频器,但 问题是你想要维修变频器又快又好!你必需有相当多的经验及维修配件!经验要长年积累,也要付出相当大的代价！ ------- How to learn maintenance converter: Many people called asking how to learn maintenance inverter, in fact, maintenance of inverter is not difficult to learn, as long as you have a bit of electronic knowledge and a little understanding of principles of right Converter, soon available Institute of Maintenance converter, but the problem is that you want to maintain rapid and sound converter! you must have considerable experience and maintenance of accessories! experience should be accumulated, but also to pay a high price! 你通常要烧毁很多变频器后才能学到一点刻骨铭心的经验！ You usually have to burn a lot of converters in order to learn a bit after the unforgettable experience! 变 频器牌子多!故障原因千变万化!又没书可查!有时要好长时间才能查出,你要有耐心和信心!最好能到变频器公司泡几年!工资低一点也没关系!维修变频器另一 个问题是配件难找!你自己最好积累一些常用的元件,要会弄清哪些元件可互换,为了降低成本,维修变频器一般用旧模块!但旧模块很多质量都有问题!每次进货 都有大部分模块质量不合格而被退货！ Inverter Multi-brand! Cause of the malfunction ever-changing! Not any books to be investigated! Sometimes taking a long time to find out, you need to have patience and confidence! Preferably to the inverter's bubble a few years! Low wages, that's fine too! Maintenance converter Another problem is hard to find parts! you the best accumulation of some common components, we should find out what components will be interchangeable, in order to reduce costs, maintenance, general inverter module with the old! but the old modules are a lot of quality problems! per the majority of modules have a second purchase of inferior quality have been returned! 所以学会检测变频器模块的好坏也是关键!大部分不合格模块就由于耐压不够（维修过的模块除外），所以你最好能拥有一个耐压表，一个200元左右，电子商场一般有卖！ So learn to detect inverter module is good or bad is also key! Most of the failed module is not enough because of pressure (except for maintenance over the module), so you better be able to have a voltage table, a 200-yuan, the electronic shopping malls are generally Sell! 我们也经常在与大家一起探讨变频器使用及维修问题，这里边有很多我们熟悉的变频器维修高手，因为他们经常在我们这里购买模块。 We also explore with you regularly use and maintenance problems inverter here while there are many we are familiar with the maintenance of the converter master, because they often purchase the module here. 有兴趣你也上去，这里边可学到不少东西！ Are interested in you go up, where margins can be a lot to learn! 维修变频器都要给客户保修，有一定风险！ Converter must repair to the customer warranty, there are certain risks! 有时还要亏本！ Sometimes at a loss! 刚入门的要有心里准备！ Just getting started to have hearts ready!
-------一体化变频器= 一次性变频器：现在有几个品牌的小功率变频器是一体化设计（输出模块、电源、推动电路固封在一起），这样只要模块有一点小故障也难以维修，换模块价格又很高（接近机价），所以只好报废！ ------- Integrated inverter = one-time converter: Now there are several brands of low-power inverter is an integrated design (output module, power supply, solid-sealed together to promote the circuit), so as long as the module has a little Fault is also difficult to maintain, change the module prices will be high (near the machine price), so had to scrap! 在中国，变频器故障率比较高有其很多客观原因，正如有一个变频器生产厂家对我们说过，同一个型号的变频器在中国使用的故障率要比在欧美地区使用的要高很多！ In China, a relatively high failure rate converter has a number of objective reasons, as there is an inverter manufacturers have told us that the same type of inverter failure rate used in China than in Europe and the United States for use of the much higher ! 所以你在购买变频器时，你必须考虑变频器可能很快就会坏的问题！ So you buy converter, you may soon be considered a bad converter problem! 如果你的工厂经常坏变频器，请不要用一次性的变频器！ If your plant often a bad inverter, please do not use a one-time converter! 已有好多工厂后悔不止！ Have been a lot of factory is more than regret!

典型应用： Typical Applications:
食品储运： 由于食品储运过程时间并不是一个短期问题，但食品保存中的相对平衡湿度又是保证食品安全的一项重要指标，相对平衡湿度直接影响菌落的生长。 Food storage and transportation: Due to the process of food storage and transportation time is not a short-term problem, but the relative balance of food preservation in the humidity to ensure food safety is an important indicator of the relative equilibrium humidity of a direct impact on colony growth. 例如：在平衡相对湿度为95%RH至91%RH范围内，易于滋生的菌落为沙门氏菌、波林特菌、乳酸菌、霉菌和酵母菌。 For example: In the equilibrium relative humidity of 95% RH to 91% RH range, the easy-to-breeding colonies of Salmonella, Bolin Te bacteria, lactic acid bacteria, mold and yeast. 而食物保存周期也与温度、平衡相对湿度有关，平衡相对湿度值为81%RH的蛋糕，其保质期为27℃时14天、21℃时24天，如果平衡相对湿度提高到85%RH，这些指标将降低为27℃ 时8天、21℃ 时12天。 And food preservation cycles and temperature, equilibrium relative humidity related to equilibrium relative humidity value of 81% RH of the cake, its shelf-life at 27 ℃ for 14 days, 21 ℃ during 24 days, if the equilibrium relative humidity increased to 85% RH These indicators will be reduced to 27 ℃ when the 8 days, 21 ℃ during 12 days. 吸湿物质的平衡相对湿度起到了决定性作用。 Equilibrium relative humidity of hygroscopic substances played a decisive role. 平衡相对湿度定义为物质与空气中水不进行交换情况下，由周围空气获取的湿度值。 Equilibrium relative humidity is defined as the material and the air in the water without the exchange of information, by the ambient air humidity values obtained. 这个定义很清楚，为了成功地储存和保持这些产品，环境气候的控制及包装必须仔细指明。 This definition is very clear, in order to successfully store and maintain these products, environment and climate control and packaging must be carefully specified. 同时，很多食品的保存在过于干燥情况下，其口感都会有些变坏。 At the same time, a lot of food stored in too dry conditions, its texture will be some deterioration. 针对这种情况，要求实时记录温湿度变化，保证食品安全进入消费者口中。 In view of this situation, require real-time records of temperature and humidity changes, to ensure food security into the mouth of consumers.
当长途运输或者海运冷冻冷藏食品时，如何在接收时证明货物一直处于规定的温湿度条件是件非常重要的事。 When the long-distance transport, or shipping frozen foods frozen, how to prove that the goods receipt has been in a prescribed temperature and humidity conditions is a very important thing. 解 决争议的做法就是在发货的时候放入货舱中一个记录仪，并启动它，温湿度记录仪有一个精密的内部时钟，忠实地记录指定时间间隔的温湿度数据，在取出时可以容 易地利用电脑察看图形文件及报警值，判断是否超过容许值,什么时候及持续时间都能轻松获得，承运方是否有责任也会立即知晓。 The practice of dispute resolution when the shipment is placed in the cargo hold in a recorder, and start it, temperature and humidity recorder with a precision internal clock, faithfully recording the specified time interval, temperature and humidity data, can be easily removed View graphic files using computers and alarm values, to determine whether to allow the value of more than at any other time and duration can easily be obtained on whether the carrier has the responsibility will be immediately known.
博物馆文物、档案管理：这是温湿度产品应用的另一个大的领域，而记录仪在其中又是很有特色的产品。 Museum artifacts, archives management: This is the product application temperature and humidity is another big area, while the recorder which is very unique products. 档案的纸张在温湿度适宜的条件可以多存放一些时间，而一旦温湿度条件遭到破坏纸张将要变脆，重要资料也将随之荡然无存，对档案馆进行温湿度记录是必要的，可以预防恶性事故的发生。 Paper files in the appropriate temperature and humidity conditions can be stored for some time more, but once the temperature and humidity conditions, the destruction of the paper will become brittle, it is important information will also be subsequently vanished without a trace of the archives is necessary to record temperature and humidity, and can to prevent accidents from happening. 使用温湿度记录仪将使温湿度记录的工作得以简化，也将节约文物保管的成本，使这一工作得以科学化，不受到过多的人为因素的干扰。 The use of temperature and humidity logger records temperature and humidity will simplify the work, will also save the cost of cultural relics preservation, so that this work to be scientific, human factors are not subject to excessive interference. 保证了对艺术品的最小破坏的前提下，文物，包括其色彩、形状不受损毁。 Ensures minimum damage to the works of art under the premise of cultural relics, including its color, shape, without damage.
建材实验： 在建材尤其是混凝土干燥过程中，我们应注意其干燥趋势，这是评价产品的指标之一，也为建筑施工方提供了可靠的数据。 Materials experiment: building materials, especially concrete drying process, we should pay attention to the drying trend, which is one of the indicators to evaluate the product, but also for building construction provided by reliable data. 应用温湿度记录仪可以将此数据记录并提供给建材研究方，将为施工提供有益的帮助。 Application of temperature and humidity data logger can use this to record and study materials available to the parties, the construction will provide useful help. 尤其是在军事建筑中，时间就是生命，准确把握混凝土干燥时间为先发致敌，为有效地将有生力量提供到战场上提供了保证。 Especially in the military construction, time is life, accurately grasp the drying time for the start of concrete caused by the enemy, in order to effectively provide vital forces to the battlefield to provide a guarantee.
农业、林业及畜牧业的应用：农业、林业及畜牧业生产，尤其一些经济作物的生产，在其幼苗期要详细记录温湿度值。 Agriculture, forestry and animal husbandry applications: agriculture, forestry and livestock production, particularly in the production of some cash crops in their seedling stage to detailed record of temperature and humidity values. 而在农业应用中，由于恶劣环境——肥料、粪便等造成的酸碱性环境使湿度产品漂移超出其他环境，这样就要求湿敏电容漂移较小、整机校准方便。 In agricultural applications, due to harsh environment - fertilizer, manure, etc., causing the pH of the environment so that drift beyond the humidity and other environmental products, this humidity sensor capacitance drift requires less machine calibration easy.
建筑验收：主要体现在智能楼宇的验收。 Building inspection: mainly embodied in the intelligent building acceptance. 由于建筑行业的验收项目多，除暖通空调指标外，其他诸如射线强度、甲醛浓度等建筑部要求符合人体健康指标也要监测，这些指标是直接关系到人体健康的。 As the construction industry acceptance over the project, in addition to HVAC indicators, other countries such as radiation intensity, the concentration of formaldehyde, the Ministry of Construction request complies with the human body but also to monitor health indicators, these indicators are directly related to human health. 如果在这些指标不明了的情况下，测试人员贸然进入这些场所并长期在其间进行记录，是对测试人员的人身健康的不负责任，而应用记录仪就会保证在取得可靠数据的同时对测试人员的人身安全进行最大保护。 If these indicators unclear circumstances, testers hastily and long-term access to these sites recorded in the period, is the personal health of the test the irresponsible, while the application of recorder will ensure access to reliable data at the same time the test The personal safety of maximum protection.
重要医卫场所：按照《医院洁净手术部建筑技术规范征求意见稿》的要求手术室的温湿度必须控制在一定的范围内：即温度在22…25℃；相对湿度45％RH…60％RH。 Important to publish health establishments: According to the "hospital clean operating department building technical specification draft," the requirements of the operating room temperature and humidity must be controlled within a certain range: the temperature at 22 ... 25 ℃; relative humidity 45% RH ... 60% RH . 适宜的环境温湿度对操作者和病人都是非常重要的。 Suitable environment temperature and humidity on the operator and the patient is very important. 当室温超过28℃，湿度大于70%RH时，易有闷热、出汗、烦燥、疲劳等反应，容易影响安定的情绪和敏捷的思维，使操作者的技术水平不能得到很好的发挥。 When the room temperature Chao Guo 28 ℃, humidity is greater than 70% RH, the tend to have a hot, sweating, irritability, fatigue and other reactions, easily affect the stability of mood and speed of thought, so that the operator's skill level can not be a good play . 同时病人也会出现心率快、出汗多等症状而增加手术难度；当室温低于20度时，只穿手术衣的操作者会感到冷，易影响操作动作的灵敏性和准确性，尤其是手指的细微动作。 At the same time the patient will also appear faster heart rate, sweating and other symptoms more difficult to increase surgery; when the temperature below 20 degrees, wear surgical clothing operators will feel cold, is likely to affect operation of the sensitivity and accuracy of movement, especially fine finger movements. 裸露的病人由于创伤机体抵抗力处于低下水平，更易发生感冒等并发症。 Naked body for the trauma patients at a lower level of resistance, more susceptible to flu complications. 室内湿度低，物体表面浮尘随某些动作，如铺单、开关门等造成气流改变而悬浮在空气中。 Indoor humidity is low, the surface dust with certain movements, such as a single shop, switches, doors, etc., causing changes in air suspended in the air. 手术间内外温差大，开门后部分区域的空气形成蜗流，风速增大到约手术间原风速的4倍，此时物体表面附着物迅速飘浮于空气中。 Large temperature difference between inside and outside the operating room, opened the door part of the region, the formation of cochlear flow of air, the wind speed increases to about surgery 4 times between the original wind speed, this time the surface attachments quickly float in the air. 根据美国CDC的调查表明手术室空气中浮游菌数在700-800cfu/m3时就有经空气感染的危险。 According to the U.S. CDC's survey shows that the number of bacteria floating in the air operating room at the 700-800cfu/m3 through the air when there is risk of infection. 从结果可见，手术时铺单至铺单后2小时空气污染最严重，此时正是手术阶段。 Can be seen from the results, surgical, when a single shop to shop alone 2 hours after the most serious air pollution at this time is the surgical phase. 由于受重力作用，室内飘尘可直接沉降到手术创面，或操作者的手或手术器械上，因此加强控制此期的空气污染对预防术后切口感染是致关重要的。 Due to gravity, indoor airborne dust deposition directly to the surgical wound, or the operator's hands or surgical instruments, so this period of greater control of air pollution on the prevention of postoperative wound infection is of crucial importance. 这些要求卫生防疫部门通过自己的监测确认各医院手术室的达标情况，记录仪是一种很好的方法，减少了人员浪费，并使执法的公正性得到保证。 These requirements health and epidemic prevention departments, through their own monitoring to confirm compliance of all hospital operating room, recording the instrument is a good way to reduce the waste of personnel and make the enforcement of fairness is guaranteed.

典型应用： Typical Applications:
食品储运： 由于食品储运过程时间并不是一个短期问题，但食品保存中的相对平衡湿度又是保证食品安全的一项重要指标，相对平衡湿度直接影响菌落的生长。 Food storage and transportation: Due to the process of food storage and transportation time is not a short-term problem, but the relative balance of food preservation in the humidity to ensure food safety is an important indicator of the relative equilibrium humidity of a direct impact on colony growth. 例如：在平衡相对湿度为95%RH至91%RH范围内，易于滋生的菌落为沙门氏菌、波林特菌、乳酸菌、霉菌和酵母菌。 For example: In the equilibrium relative humidity of 95% RH to 91% RH range, the easy-to-breeding colonies of Salmonella, Bolin Te bacteria, lactic acid bacteria, mold and yeast. 而食物保存周期也与温度、平衡相对湿度有关，平衡相对湿度值为81%RH的蛋糕，其保质期为27℃时14天、21℃时24天，如果平衡相对湿度提高到85%RH，这些指标将降低为27℃ 时8天、21℃ 时12天。 And food preservation cycles and temperature, equilibrium relative humidity related to equilibrium relative humidity value of 81% RH of the cake, its shelf-life at 27 ℃ for 14 days, 21 ℃ during 24 days, if the equilibrium relative humidity increased to 85% RH These indicators will be reduced to 27 ℃ when the 8 days, 21 ℃ during 12 days. 吸湿物质的平衡相对湿度起到了决定性作用。 Equilibrium relative humidity of hygroscopic substances played a decisive role. 平衡相对湿度定义为物质与空气中水不进行交换情况下，由周围空气获取的湿度值。 Equilibrium relative humidity is defined as the material and the air in the water without the exchange of information, by the ambient air humidity values obtained. 这个定义很清楚，为了成功地储存和保持这些产品，环境气候的控制及包装必须仔细指明。 This definition is very clear, in order to successfully store and maintain these products, environment and climate control and packaging must be carefully specified. 同时，很多食品的保存在过于干燥情况下，其口感都会有些变坏。 At the same time, a lot of food stored in too dry conditions, its texture will be some deterioration. 针对这种情况，要求实时记录温湿度变化，保证食品安全进入消费者口中。 In view of this situation, require real-time records of temperature and humidity changes, to ensure food security into the mouth of consumers.
当长途运输或者海运冷冻冷藏食品时，如何在接收时证明货物一直处于规定的温湿度条件是件非常重要的事。 When the long-distance transport, or shipping frozen foods frozen, how to prove that the goods receipt has been in a prescribed temperature and humidity conditions is a very important thing. 解 决争议的做法就是在发货的时候放入货舱中一个记录仪，并启动它，温湿度记录仪有一个精密的内部时钟，忠实地记录指定时间间隔的温湿度数据，在取出时可以容 易地利用电脑察看图形文件及报警值，判断是否超过容许值,什么时候及持续时间都能轻松获得，承运方是否有责任也会立即知晓。 The practice of dispute resolution when the shipment is placed in the cargo hold in a recorder, and start it, temperature and humidity recorder with a precision internal clock, faithfully recording the specified time interval, temperature and humidity data, can be easily removed View graphic files using computers and alarm values, to determine whether to allow the value of more than at any other time and duration can easily be obtained on whether the carrier has the responsibility will be immediately known.
博物馆文物、档案管理：这是温湿度产品应用的另一个大的领域，而记录仪在其中又是很有特色的产品。 Museum artifacts, archives management: This is the product application temperature and humidity is another big area, while the recorder which is very unique products. 档案的纸张在温湿度适宜的条件可以多存放一些时间，而一旦温湿度条件遭到破坏纸张将要变脆，重要资料也将随之荡然无存，对档案馆进行温湿度记录是必要的，可以预防恶性事故的发生。 Paper files in the appropriate temperature and humidity conditions can be stored for some time more, but once the temperature and humidity conditions, the destruction of the paper will become brittle, it is important information will also be subsequently vanished without a trace of the archives is necessary to record temperature and humidity, and can to prevent accidents from happening. 使用温湿度记录仪将使温湿度记录的工作得以简化，也将节约文物保管的成本，使这一工作得以科学化，不受到过多的人为因素的干扰。 The use of temperature and humidity logger records temperature and humidity will simplify the work, will also save the cost of cultural relics preservation, so that this work to be scientific, human factors are not subject to excessive interference. 保证了对艺术品的最小破坏的前提下，文物，包括其色彩、形状不受损毁。 Ensures minimum damage to the works of art under the premise of cultural relics, including its color, shape, without damage.
建材实验： 在建材尤其是混凝土干燥过程中，我们应注意其干燥趋势，这是评价产品的指标之一，也为建筑施工方提供了可靠的数据。 Materials experiment: building materials, especially concrete drying process, we should pay attention to the drying trend, which is one of the indicators to evaluate the product, but also for building construction provided by reliable data. 应用温湿度记录仪可以将此数据记录并提供给建材研究方，将为施工提供有益的帮助。 Application of temperature and humidity data logger can use this to record and study materials available to the parties, the construction will provide useful help. 尤其是在军事建筑中，时间就是生命，准确把握混凝土干燥时间为先发致敌，为有效地将有生力量提供到战场上提供了保证。 Especially in the military construction, time is life, accurately grasp the drying time for the start of concrete caused by the enemy, in order to effectively provide vital forces to the battlefield to provide a guarantee.
农业、林业及畜牧业的应用：农业、林业及畜牧业生产，尤其一些经济作物的生产，在其幼苗期要详细记录温湿度值。 Agriculture, forestry and animal husbandry applications: agriculture, forestry and livestock production, particularly in the production of some cash crops in their seedling stage to detailed record of temperature and humidity values. 而在农业应用中，由于恶劣环境——肥料、粪便等造成的酸碱性环境使湿度产品漂移超出其他环境，这样就要求湿敏电容漂移较小、整机校准方便。 In agricultural applications, due to harsh environment - fertilizer, manure, etc., causing the pH of the environment so that drift beyond the humidity and other environmental products, this humidity sensor capacitance drift requires less machine calibration easy.
建筑验收：主要体现在智能楼宇的验收。 Building inspection: mainly embodied in the intelligent building acceptance. 由于建筑行业的验收项目多，除暖通空调指标外，其他诸如射线强度、甲醛浓度等建筑部要求符合人体健康指标也要监测，这些指标是直接关系到人体健康的。 As the construction industry acceptance over the project, in addition to HVAC indicators, other countries such as radiation intensity, the concentration of formaldehyde, the Ministry of Construction request complies with the human body but also to monitor health indicators, these indicators are directly related to human health. 如果在这些指标不明了的情况下，测试人员贸然进入这些场所并长期在其间进行记录，是对测试人员的人身健康的不负责任，而应用记录仪就会保证在取得可靠数据的同时对测试人员的人身安全进行最大保护。 If these indicators unclear circumstances, testers hastily and long-term access to these sites recorded in the period, is the personal health of the test the irresponsible, while the application of recorder will ensure access to reliable data at the same time the test The personal safety of maximum protection.
重要医卫场所：按照《医院洁净手术部建筑技术规范征求意见稿》的要求手术室的温湿度必须控制在一定的范围内：即温度在22…25℃；相对湿度45％RH…60％RH。 Important to publish health establishments: According to the "hospital clean operating department building technical specification draft," the requirements of the operating room temperature and humidity must be controlled within a certain range: the temperature at 22 ... 25 ℃; relative humidity 45% RH ... 60% RH . 适宜的环境温湿度对操作者和病人都是非常重要的。 Suitable environment temperature and humidity on the operator and the patient is very important. 当室温超过28℃，湿度大于70%RH时，易有闷热、出汗、烦燥、疲劳等反应，容易影响安定的情绪和敏捷的思维，使操作者的技术水平不能得到很好的发挥。 When the room temperature Chao Guo 28 ℃, humidity is greater than 70% RH, the tend to have a hot, sweating, irritability, fatigue and other reactions, easily affect the stability of mood and speed of thought, so that the operator's skill level can not be a good play . 同时病人也会出现心率快、出汗多等症状而增加手术难度；当室温低于20度时，只穿手术衣的操作者会感到冷，易影响操作动作的灵敏性和准确性，尤其是手指的细微动作。 At the same time the patient will also appear faster heart rate, sweating and other symptoms more difficult to increase surgery; when the temperature below 20 degrees, wear surgical clothing operators will feel cold, is likely to affect operation of the sensitivity and accuracy of movement, especially fine finger movements. 裸露的病人由于创伤机体抵抗力处于低下水平，更易发生感冒等并发症。 Naked body for the trauma patients at a lower level of resistance, more susceptible to flu complications. 室内湿度低，物体表面浮尘随某些动作，如铺单、开关门等造成气流改变而悬浮在空气中。 Indoor humidity is low, the surface dust with certain movements, such as a single shop, switches, doors, etc., causing changes in air suspended in the air. 手术间内外温差大，开门后部分区域的空气形成蜗流，风速增大到约手术间原风速的4倍，此时物体表面附着物迅速飘浮于空气中。 Large temperature difference between inside and outside the operating room, opened the door part of the region, the formation of cochlear flow of air, the wind speed increases to about surgery 4 times between the original wind speed, this time the surface attachments quickly float in the air. 根据美国CDC的调查表明手术室空气中浮游菌数在700-800cfu/m3时就有经空气感染的危险。 According to the U.S. CDC's survey shows that the number of bacteria floating in the air operating room at the 700-800cfu/m3 through the air when there is risk of infection. 从结果可见，手术时铺单至铺单后2小时空气污染最严重，此时正是手术阶段。 Can be seen from the results, surgical, when a single shop to shop alone 2 hours after the most serious air pollution at this time is the surgical phase. 由于受重力作用，室内飘尘可直接沉降到手术创面，或操作者的手或手术器械上，因此加强控制此期的空气污染对预防术后切口感染是致关重要的。 Due to gravity, indoor airborne dust deposition directly to the surgical wound, or the operator's hands or surgical instruments, so this period of greater control of air pollution on the prevention of postoperative wound infection is of crucial importance. 这些要求卫生防疫部门通过自己的监测确认各医院手术室的达标情况，记录仪是一种很好的方法，减少了人员浪费，并使执法的公正性得到保证。 These requirements health and epidemic prevention departments, through their own monitoring to confirm compliance of all hospital operating room, recording the instrument is a good way to reduce the waste of personnel and make the enforcement of fairness is guaranteed.

Programmable Logic Controller
A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or lighting fixtures. PLCs are used in many industries and machines, such as packaging and semiconductor machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed or non-volatile memory. A PLC is an example of a real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result.

It is very outdated. It does not feature modern refrigerants, tools, or service techniques. While some of the information will always be applicable to the field, the information is researched, borrowed...not from the authors' experience in the field. My father was teaching me in the late 1960's. Had he given me this book I would have thought it useful but a bit old fashioned. You can tell the authors do not practice in the field or the shop or they would have realized their information was from the refrigeration dinasaur age!
