摘要：

为提高现有热源塔式空气源热泵的效率和适应性，提出一种以盐水为传热工质的可调型盐水聚能塔式空气源热泵的新概念. 设计并搭建基于该新型热泵的热水供应系统.对夏冬2季典型月份内系统的性能进行分析和比较，阐明系统的性能系数随环境温湿度、供/回水量和温度、补水温度以及耗电量之间的变化关系. 结果表明，系统的总性能系数、加热系统和热泵内循环的性能系数在夏季的平均值分别为1.44、1.75和3.55，而在冬季则为2.07、2.33和3.29.该系统已经成功运行1 a以上，在冬季气温低于0  ℃时依然运行平稳.

Abstract:

To improve the efficiency and adaptability of the existing energy tower-based air-source heat pumps，a new concept of tunable air-source heat pumps was proposed based on saltwater energy towers. A hot-water system incorporated with this new type of heat pumps was designed and constructed. The performance of the system was analyzed and compared between typical summer and winter months. Variations of the coefficient of performance (COP) of the system were presented as functions of ambient temperature and humidity，flow rate and temperature of supplying/recirculating water， make-up water temperature, and power consumption. The COPs of the entire system，heating portion，and heat pump were 1.44，1.75 and 3.55 for summer，respectively，whereas those were 2.07，2.33 and 3.29 for winter. The system had been operated successfully for more than 1 a and was running well below 0  ℃ in winter.
