摘　　要：利用空调系统的全寿命周期成本(LCC)的构成以及数学计算模型对重庆某地表水源热泵工程的全寿命周期成本进行了计算。结果表明,系统设置不合理,地表水源热泵的LCC值并非是最低的,会高于其他空调系统;而合理的地表水源热泵方案才能够得到最低的LCC值。对实际测试的数据进行了分析,找到了影响地表水源热泵的LCC值的主要因素有负荷特征、取水能耗和取水水温等。最后指出了取得最低的LCC值应注意的问题.Based on the structure and mathematical model of life cycle total cost in air-conditioning system,the life cycle total cost of a surface water heat pump system in Chongqing is calculated.The results show that the system settings are not reasonable;the LCC is not always the lowest,and sometimes it may be higher than other air-conditioning systems.Only the reasonable scheme can get the lowest LCC.Through analyzing the actual test data,the load characteristic,water supply energy consumption,water supply temperature and other main factors are found that can influence LCC of surface water heat pump.Finally,matters which require attention in obtaining the lowest LCC are pointed out.

关 键 词：地表水源热泵 全寿命周期成本 负荷特征 取水能耗 取水水温
