摘要
介绍带回热器的跨临界CO2热泵热水试验系统。通过改变气冷器水流量对跨临界CO2水-水热泵多种工况的循环性能进行试验研究,获得一系列试验数据。试验结果表明:跨临界CO2热泵循环可获得比常规工质要高的出水温度;增加气冷器水流量可有效提高系统的制热系数。
Presents water source heat pump system with the CO2 transcritical cycle and a regenerator for experiment.Carries out series of experiments under different operation conditions by changing water flow of gas cooler.The experimental results show that the transcritical CO2 cycle is advantageous over those conventional refrigerants cycle,and COPh of the system can be enhanced effectively by increasing water flow of gas cooler.
