摘　　要：为了提高新风机组的除湿能力与供能系统的能源利用效率,提出了CCHP预冷除湿型单级转轮除湿复合空调系统和CCHP两级转轮除湿复合空调系统。以上海市某酒店建筑为研究对象,应用DesignBuilder软件计算了建筑的各项负荷,基于Dymola仿真平台建立了转轮除湿新风机组模型与供能系统模型,并进行了动态仿真。结果表明:与常规空调系统相比,两种转轮除湿复合空调系统均更具节能潜力与环保效益,且两级系统的节能性更优,单级系统的除湿能力与运行稳定性更好;CCHP单级系统和CCHP两级系统的全年化石能源消耗总量分别下降61.1%,77.85%,年CO_(2)排放量分别减少了30.08%,29.62%。In order to improve the dehumidification capacity of the fresh air handling unit and the efficiency of energy utilization of the energy supply system,the CCHP pre-cooling dehumidification single-stage desiccant wheel hybrid air conditioning system and CCHP two-stage desiccant wheel hybrid air conditioning system were proposed.Taking a hotel in Shanghai as the research object,the DesignBuilder software was used to calculate the loads of the building.Dymola,a kind of simulation platform,was used to establish the desiccant wheel fresh air handling unit model and energy supply system model,and the dynamic simulation was carried out.The results indicate that the two desiccant wheel hybrid air conditioning systems have more energy saving potential and environmental protection benefits compared with the conventional air conditioning system.And the two-stage system has better energy saving performance,but it dehumidification ability and operation stability are inferior to the single-stage system.The annual fossil energy consumption of CCHP single-stage system and CCHP two-stage system decrease by 61.1%and 77.85%,respectively,and annual carbon dioxide emissions of them decrease by 30.08%and 29.62%,respectively.
