CHP联合热湿独立处理空调系统及动态仿真

CHP Combined Heat and Humidity Independent Treatment Air Conditioning System and Dynamic Simulation

将燃气内燃机热电联供系统与热湿独立处理空调系统(采用固体除湿转轮)组成复合空调系统,利用燃气内燃机余热进行除湿转轮再生。以上海某医院ICU层为用户,使用动态仿真方法对常规分供空调系统(1台燃气锅炉全年运行用以制备生活热水,1台燃气锅炉仅在供暖期开启以制备供暖热水,2台电制冷机仅在供冷期开启为室内风机盘管提供冷水)、复合空调系统的一次能源利用率、动态投资回收期进行对比。对于复合空调系统,由于供冷期存在相对稳定的再生热负荷,燃气内燃机全年负荷水平更加均匀,有利于延长设备寿命。常规分供空调系统、复合空调系统的一次能源利用率分别为75.8%、87.9%。与常规分供空调系统相比,复合空调系统的动态投资回收期缩短了84.3%。

A composite air-conditioning system is composed of a gas engine cogeneration system and a heat and humidity independent treatment air-conditioning system(using solid dehumidification runner),and the dehumidification runner is regenerated by using the waste heat of the gas engine.Taking the ICU floor of a hospital in Shanghai as the user,the primary energy utilization rate and dynamic investment payback period of conventional distributed air-conditioning system(One gas-fired boiler operates throughout the year to prepare domestic hot water,one gas-fired boiler only operates during the heating period to prepare heating hot water,and two electric refrigerators only operates during the cooling period to provide cooling water for the indoor fan coil.)and composite air-conditioning system are compared by using dynamic simulation method.For the composite air-conditioning system,due to the relatively stable regenerative heat load during the cooling period,the annual load level of gas engine is more uniform,which is conducive to prolonging the life of the equipment.The primary energy utilization rates of conventional distributed air-conditioning system and the composite air-conditioning system are 75.8%and87.9%,respectively.Compared with the conventional distributed air-conditioning system,the dynamic investment payback period of the composite air-conditioning system is shortened by 84.3%.
