| 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试验。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。

| Abstract: | To solve the idle problem of chillers and the frosting problem of air-source heat pumps in winter, a heat pump system based on heat-source tower was proposed.The structure and work process of this system were analyzed in detail, and an experimental device of heat-source tower heat pump was built.The heating experiments with the variation temperature difference of solution between the heat-source tower inlet and outlet were carried out.The experimental results showed that the heating capacity of the heat pump and COP were decreased, the power consumption of compressor changed little, and the difference between air temperature and evaporating temperature was enlarged when the temperature difference of solution between the heat-source tower inlet and outlet increased. The COP of heat pump declined from 3.02 to 2.72, and the difference between air temperature and evaporating temperature enhanced from 7.64℃ to 11.96℃, when the environment temperature was -1.2℃,and the temperature difference of solution between the heat-source tower inlet and outlet changed from 1.5℃ to 3℃. The operation of this system was stable and reliable during the whole experiment, and the frosting problem was avoided.The results indicate that the heat-source tower heat pump is a very promising scheme for heating/cooling. |
