摘　　要：为提高低温地热水资源夏季供冷能效,结合地热冬季用水源热泵,提出了地热能液体除湿、热泵供冷的联合运行空调系统。通过编制水—水热泵模拟程序,计算得出了热泵在制取高温冷冻水工况下的运行参数,同时对地热能液体除湿的可行性方案进行了分析,进而对整个系统能效及运行经济性做出了判定,指出地热能液体除湿与热泵空调联合系统将是目前低温地热供冷的最佳模式。In order to improve the energy eiticiency of low-temperature geothermal water resource for refrigerating in summer, a combined geothermal water-source heat pump and geothermal energy liquid desiccant dehumidification system is proposed in this paper. The operating parameters of heat pump under the refrigerating regime are calculated using a compiled simulated program of water-to-water heat pump. Then the paper analyzed the feasi- bility of geothermal liquid desiccant dehumidification, the energy efficiency and the running costs of the system. And the results indicate that the combined system of the geothermal energy liquid desiccant dehumidification and heat pump air-conditioning is a better operation mode for low-temperature geothermal energy utilization in summer.
