A continuous air-conditioning system with a ceiling plenum chamber is studied in order to reduce the peak power demand in the daytime and to improve the thermal environment in an office building. Two computer programs, one is based on the absorption factor method and another is based on the environmental temperature method are developed for more accurate simulation on aspect of radiative heat transfer.The latter is practical because its simple input. A series of simulation for the model office building are carried out to examine the performance of the air-conditioning system. The results shows that this system is beneficial in regards to thermal storage and its MRT is lower then any other system. It is also found that swinging room temperature to some degree during the day can reduce the peak cooling load in the afternoon more effectively. And 1/3 reduction of the peak cooling load is obtained by measurements using a continuous air-conditioning with a ordinary duct system.

为了减少白天的峰值电力需求，改善办公大楼的热环境，研究了一种带有天花板充气室的连续空调系统。为了对辐射传热进行更精确的模拟，开发了基于吸收因子法和基于环境温度法的计算机程序。后者是实用的，因为它的输入简单。对模型办公楼进行了一系列的仿真，以检验空调系统的性能。结果表明，该系统有利于储热，其MRT低于其他系统。研究还发现，将室内温度在白天进行一定程度的调节，可以更有效地降低下午的峰值冷负荷。采用普通风管系统的连续空调进行测量，可使峰值冷负荷降低1/3。
