摘 要 ：为解决水冷冷水机组冬季闲置和空气源热泵冬季制热存在的结霜问题，构建了一种基于热源塔的热源塔热泵系统。详细分析了热源塔热泵系统的构成和工作过程，依据所建立的热源塔热泵试验装置进行了不同热源塔溶液进出口温差的制热实验。结果表明：热泵制热量和COP都随着热源塔溶液进出口温差的增大而减小，而压缩机的耗功变化较小，空气与蒸发温度间的温差随之增大而增加；当环境温度为-1.2℃，热源塔溶液进出口温差从1.5℃增大到3℃时，热泵制热COP由3.02降为2.72，空气与蒸发温度的温差由7.64℃增大至11.96℃。整个实验过程中系统运行稳定可靠，避免了空气源热泵的结霜问题，表明热源塔热泵是一种非常具有前景的冷热源方案。 关键词 ：热源塔 热泵 供热系统 性能 试验 The Construction And Experimental Study Of Heat Pump System Based On Heat-Source Tower Abstract: In order to solve the idle problem of chillers and the frosting problem of air-source heat pumps in winter, a heat-source tower heat pump based on heat-source tower was proposed, which structure and work process were analyzed in detail. A heat-source tower heat pump test device was built and the heating experiments under the different range of solution temperature between the heat-source tower inlet and outlet were carried out. The experimental results showed that the heating quantity of heat pump and its COP were declined, the power consumption of compressor was changed little, and the temperature difference between air and evaporating temperature was enhanced, when the solution temperature difference between the heat-source tower inlet and outlet was increased; The COP of heat pump was decreased form 3.02 to 2.72, and the temperature difference between air and evaporating temperature was increased form 7.64℃ to 11.96℃, when the environment temperature was -1.2℃,and the solution temperature difference between the heat-source tower inlet and outlet was changed form 1.5℃ to 3℃. The system operation was stable and reliable during the whole experimental process, and the frosting problem was avoided. It indicates that the heat-source tower heat pump is a kind of very promising scheme for heating/cooling. Keywords: heat-source tower; heat pump; heating system; performance; experiment
