近年来发展较快的冷却顶板空调系统是*种将显热负荷与湿负荷分开处理的空调系统。目前普遍采用的是通过冷却顶板消除显热负荷，借助机械制冷，对处理空气冷却去湿，通过通风系统来消除湿负荷。从理论上对转轮除湿机应用于冷却顶板空调系统的情况进行计算分析，讨论其应用的可能性和节能效果。

　　舒适性空调系统设计的主要目的是要保持室内*定的温度和湿度，所以需对空气进行加热、冷却、去湿等处理。

　　冷却顶板空调系统中，冷却顶板只能除去室内的显热负荷，无法除去室内的湿负荷。如果不除去室内的湿负荷，则不但会引起室内空气的湿度不断升高，使人感觉越来越不舒服，而且会引起室内空气露点温度不断升高，到*定程度时高于冷却顶板的表面温度，造成冷却顶板结露。同时室内空气要满足卫生要求，需补充*定量的新风。因此，在冷却顶板空调系统的设计中，常用冷却顶板除去室内的显热负荷，用经过处理的新风除去室内的湿负荷。

　　In recent years, the rapid development of cooling roof air conditioning system is a kind of air conditioning system which separates sensible heat load from wet load. At present, it is generally adopted to eliminate the sensible heat load by cooling the roof, and to cool the air by means of mechanical refrigeration, and to eliminate the wet load through the ventilation system. The calculation and analysis of the application of the rotary dehumidifier to the cooling roof air conditioning system are carried out in theory, and the possibility of application and the effect of energy saving are discussed.

　　The main purpose of comfort air conditioning system design is to maintain a certain indoor temperature and humidity, so the heating of the air, cooling, dewetting and so on.

　　In the cooling ceiling air conditioning system, the cooling ceiling can only remove the apparent heat load in the room, and can not remove the indoor wet load. If the moisture load is removed, it will not only cause the indoor air humidity increases, make people feel more and more uncomfortable, but also causes the indoor air dew point temperature rising, to a certain extent than the surface temperature of the cooling ceiling and roof cooling caused by condensation. At the same time, indoor air should meet the hygienic requirements, and a certain amount of fresh air should be added. Therefore, in the design of cooling ceiling air conditioning system, the cooling ceiling is usually used to remove the sensible heat load, and the fresh air is used to remove the indoor moisture load.
