摘　　要：以某高校作为算例,分析并设计了该高校冷热负荷需求,并依此负荷比较了地下水源热泵、土壤源热泵和土壤源热泵+冷却塔系统3种空调方案的设备选型、初始投资费用、运行费用以及LCC动态经济状况。通过比较发现:土壤源热泵系统初投资高于地下水源热泵,低于土壤源热泵+冷却塔系统,运行费用最低;土壤源热泵+冷却塔系统初投资和运行费用都是最高;土壤源热泵系统比地下水源热泵系统年运行费用可以节省29.7%,寿命期内费用现值和费用年值均可节省8.6%,并可在3年～4年内收回初始投资,其社会经济效益十分显著,可为周围高校的空调使用提供有利的参考数据。This paper takes a university as an example to analyze and design the hot and cold load demand of the university,and compare the selection of three air-conditioning schemes for groundwater heat pump,ground-source heat pump and ground-source heat pump+cooling tower system,initial investment cost,operating cost and LCC dynamic economic conditions.It is found that the initial investment of the ground-source heat pump system is higher than that of the groundwater heat pump,which is lower than that of the ground-source heat pump+cooling tower system.The operating cost is the lowest.The initial investment and operating cost of the ground-source heat pump+cooling tower system are the highest.The operating cost of ground-source heat pump can save 29.7%,the current value and the annual value of the cost can save 8.6%,and in 3 to 4 years to recover the initial investment.Its social and economic benefits are significant.The conclusion can provide favorable reference data for the air-conditioning use of the surrounding colleges and universities.
