摘要(Abstract)：

针对某医院示范改造项目应用R32空气源热泵系统的供暖运行性能开展试验研究,分析示范建筑的环境温度及室内温度变化情况,计算R32热泵系统的总制热量、总能耗和供暖季综合性能系数,并研究系统在低环境温度下的运行情况。结果表明,R32空气源热泵的供暖效果良好,整个供暖季的系统综合性能系数为2.91,室内平均温度达17.8℃,在环境温度为-12.5℃左右时,R32空气源热泵系统的供水温度约为41℃,平均系统能效为2.2。
Experimental research was conducted for a demonstrative reconstruction project of a hospital-the operating performance of R32 air-source heat pump application. The environmental temperature and indoor temperature change of the demonstration building were analyzed,the total heating capacity,total energy consumption and the heating season comprehensive performance coefficient of the R32 air-source heat pump system were calculated,and operation performance of the system under low environmental temperature was studied. The results show that the R32 air-source heat pump had better heating effect. The comprehensive performance coefficient of the system in the whole heating season was 2.91,the average indoor temperature reached17.8 ℃,and when the ambient temperature was -12.5 ℃,the water supply temperature of the heat pump system was about 41 ℃and the average energy efficiency of the system was 2.2.
