| 水源热泵技术利用少量电能将地表水或地下水的低品位能量转移至高品位，目前正成为节能领域的研究热点.针对水源热泵变冷凝参数的相关研究缺乏的现状，通过搭建水源热泵热水器实验台进行了相应实验研究.在水流量Q为0.7~1.3 m3·h-1，进水温度t为15~30 ℃范围内，对系统功耗、制热量、制冷量、热泵性能系数COP等参数进行了测量.实验结果表明，在水流量为1.1 m3·h-1，进水温度为20 ℃时，COP达到最大值，系统平均热泵性能系数COPave为3.23，此时系统处于最佳运行工况.由此可知，寻找系统的最佳运行工况对热泵系统设计和实际工程应用具有重要的意义. |

| The water source heat pump technology is used to convert low-grade energy in surface water or groundwater to high-grade energy using a small amount of electricity and is becoming a hot spot of energy saving research.Up to now,investigations on variable condensate parameters of the water source heat pump have been rarely made.In this paper,a water source heat pump water heater test bench was built and experiments were carried out.The input power,the heating capacity,the cooling capacity,and the Coefficient Of Performance COP were measured in the range of water flow Q from 0.7 m3·h-1 to 1.3 m3·h-1 and in the range of inlet water temperature t from 15 ℃to 30 ℃.The experimental results indicated that COPave reaches its maximum,namely 3.23,at Q=1.1 m3·h-1 and t=20 ℃,and by this time the system is in the best operating condition.Therefore,looking for the best operating conditions of the system is of great significance for heat pump system design and practical application. |
