Clean room should be equipped with air conditioning system: different use time; different temperature and humidity benchmarks and allowable fluctuation range; different noise standards require different air conditioning areas with muffling requirements and noise generation; different air cleanliness standards require different requirements; air conditioning areas requiring heating and cooling need to be used together, which should be high standards for air conditioning areas. Seek to do. The air-conditioning and air-conditioning systems in the air-conditioning areas with different local demands will be difficult to control and influence the use. Therefore, the air-conditioning and air-conditioning systems should be set up separately to emphasize the different needs of the air-conditioning and air-conditioning systems. When individual local standards are higher than those required in other major air-conditioning and air-conditioning areas, the setting of clean air-conditioning systems will reduce the cost of the systems The air conditioning system can be shared; the air conditioning area with higher standard should be treated, just as the air conditioning area with different requirements for cleanliness or noise in the first air system, the air conditioning area with higher requirements for cleanliness or noise should be treated with filters or mufflers that meet the requirements.
全空气空调系统的策划应符合:采取应用单风道系统;当送风温差较大时，应采取应用一次回风系统。当送风温差较小，相对湿度要旨不严格时，可采取应用二次回风系统。除严格要旨温湿度波动范围的空调区域外，同一空气处理系统内不得再是进行加热和冷却过程。采取应用空调系统的送风温度是经常改动的热水和冷水流的方式,但不常改动一、二次回风比复杂的把握系统,再是由于中小学回风比的改动会影响房间内部相对湿度的稳定性是不适合大量的水分和湿度要旨更严格的空调区,以是不适用于热的上提下,一般工程系统推荐为easy、易于把握的回风系统。较低的送风方式或洁净室空调系统，使送风与送风温差较小。为避免系统再热引起的冷却热偏置，可采取应用二次回风系统。一般环境下，除了温湿度波动范围严格的空调 技术实现 外，同样的空气处理系统也不应增加冷热过程，因为冷热竞相抵消，不符合节能的原则。仲景全球净化可供给洁净室、洁净室咨询、计划、策划、正式动土、安装、改造等配套效劳
The design of all-air air conditioning system should conform to the following: single air duct system; primary return air system should be adopted when the temperature difference of supply air is large. When the temperature difference of air supply is small and the relative humidity requirement is not strict, the secondary return air system can be used. Except in the air conditioning area where temperature and humidity fluctuations are strictly required, heating and cooling processes shall not be carried out simultaneously in the same air handling system. The air supply temperature of air conditioning system is the way of hot water and cold water flow, but the complex control system of primary and secondary air return ratio is not often changed. At the same time, because the change of primary and secondary air return ratio will affect the stability of indoor relative humidity, it is not suitable for a large number of air conditioning areas with stricter moisture and humidity requirements, so it is not suitable for air conditioning areas. On the premise of heat, the general engineering system is recommended as a simple and easy-to-control return air system. Lower air supply mode or clean room air conditioning system makes the temperature difference between air supply and air supply smaller. Secondary return air system can be used to avoid cooling heat bias caused by system reheat. In general, in addition to air conditioning technology with strict fluctuation range of temperature and humidity, the same air handling system should not increase the heat and cold process, because the heat and cold offset each other, which does not meet the principle of energy saving.

全空变风量空调系统的策划应符合:按建筑模块和负荷改动计划空调面积;系统形式应按照空调效劳区域的计划、使用时间、负荷改动等，通过 技术实现 经济比较细目。变风量末端装置应为压力无关型;应采取措施确保低新风量要旨;大体积送风空调区域和系统要按照夏季冷负荷细目空调区和系统体积和小的空气供应空调区域应按照负载改动和空气分布决定的,等等。风机应变速调节。当内区独立使用全年供冷变风量空调系统时，外区可按照外区空调负荷特点设置风机盘管空调系统和定风量空调系统。变风量空调空气处理装置一起使用时在内部和外部区域,单风道变风量空调末端装置的类型可用于内部区域,而变风量空调终端设备与再热器中设置外区按照空调负荷特点外区。内外区设置变风量空气处理机组时，内区机组只需要全年制冷，外区机组需要季节制冷或换热。再是按照方向在外区设置空气处理单圆，以保证各系统各终端设备的转换时间一致。变风量空调系统末端的设备类型多,按照是否补偿系统压力改动可分为独立式和压力型两种,末端的压力无关型管道系统内的压力改动时,压力改动引起的空气体积改动检测和反馈把握器的结束,把握器通过调节阀的开启来补偿风量的改动，对当上主变风量末端装置的压力没有尽数影响。
The design of VAV air conditioning system should conform to the following requirements: air conditioning area should be divided according to building module and load change; system form should be determined by comparing technology and economy according to the division of air conditioning service area, service time, load change, etc. Variable air volume terminal device should be pressure independent; measures should be taken to ensure minimum fresh air demand; maximum volume air supply air conditioning area and system should be determined according to summer cooling load; minimum air supply air conditioning area should be determined according to load change and air distribution, etc. Fan strain speed regulation. When the inner zone uses the year-round variable air volume air conditioning system independently, the outer zone can set fan coil unit air conditioning system and constant air volume air conditioning system according to the load characteristics of the outer zone air conditioning. When the VAV air conditioning air handling device is used together in the internal and external areas, the type of single-channel VAV air conditioning terminal device can be used in the internal areas, while the VAV air conditioning terminal equipment and reheater set the external areas according to the characteristics of air conditioning load. When variable air volume air handling units are installed in the inner and outer areas, the inner units only need year-round refrigeration, while the outer units need seasonal refrigeration or heat transfer. At the same time, according to the direction, the air handling unit is set up in the outer area to ensure that the conversion time of each terminal equipment in each system is the same. There are many types of equipment at the end of VAV air conditioning system. According to whether or not the pressure change of compensation system can be divided into two types: independent type and pressure type. When the pressure changes in the pressure-independent pipe system at the end, the air volume change caused by the pressure change is detected and the feedback controller is terminated. The controller compensates the air volume by adjusting the opening of the valve. The change has no effect on the pressure of the current main transformer air flow terminal device.
