摘　　要：本文建立了基于PV/T和GHP再生的转轮除湿空调系统,构建了除湿转轮子系统仿真模块、燃气热泵子系统仿真模块和PV/T子系统仿真模块,并在此基础之上构建整机系统仿真模块。对不同处理空气流量、处理空气温度、处理空气湿度、转轮转速、太阳光照、发动机转速及有无预冷器的空调系统性能进行了仿真模拟。主要结论有:处理空气风量越大、入口温度越高、入口湿度越小、转轮转速越低则空调系统的除湿量越小;处理空气风量越大、入口温度越高、入口湿度越大、转轮转速越高,则蒸发温度越高,制冷COP越大;发动机转速越大,系统的再生温度越高、送风温度越低、冷凝温度越高、蒸发温度越高、除湿量越大;太阳光照强度越强,系统的除湿量就越大;有预冷器的空调系统除湿量更大。In this paper,a kind of desiccant wheel air conditioning system regenerated by PV/T and GHP is introduced,desiccant wheel subsystem simulation module,gas heat pump subsystem simulation module and PV/T subsystem simulation module are constructed,and on this basis,the whole system simulation module is built. we had carried on the simulation of air conditioning system for different process air flow,air temperature,air humidity,wheel speed,sun light intensity,engine speed and presence of precooler. Main conclusions are： the larger the processing air volume or the higher the temperature or the smaller the humidity or the lower the speed of wheel is,then the smaller the dehumidification amount is; the larger the processing air volume or the higher the temperature or the humidity or the speed of wheel or the evaporation temperature is,then the higher the COP is; the higher the speed of engine is, then the higher the regeneration temperature and the condensing temperature and the evaporating temperature and dehumidification amount,and the lower the supply air temperature is; the stronger the sun light intensity is,the greater the amount of dehumidification is; the air conditioning system which have a precooler have a higher dehumidification amount.
