在作者设计和建立的实验台上进行了CO2 跨临界水—水热泵多种工况的循环性能实验研究 ,系统运行稳定、调节方便。实验结果表明 ,系统运行时的最大制冷 (热 )系数取决于系统的蒸发温度和气体冷却器出口温度。CO2 跨临界循环热泵较之传统工质热泵具有较大优势 ,尤其是在高温热泵领域。指出了系统的改善措施
Experimental study on the performance of CO2 transcritical water-water heat pump was carried out on the experimental platform designed and set up by the author. The system is stable and easy to adjust. The experimental results show that the maximum cooling (heating) coefficient when the system is running depends on the evaporation temperature of the system and the exit temperature of the gas cooler. The transcritical CO2 heat pump has more advantages than the traditional working fluid heat pump, especially in the field of high temperature heat pump. Pointed out the system improvement measures
