本文以广州某高校学生宿舍空气源热泵热水系统为对象,对直热式空气源热泵热水系统的运行性能进行了实测研究。结果表明:在环境平均温度23.27℃、进水平均温度24.83℃的条件下,空气源热泵热水系统平均COP约3.67,机组COP达4.47以上,具有良好的运行性能和节能效果,但是在热水供应和热水储存期间,以管道、阀门、水箱为主的热水系统仍存在一些问题有待改善。
In this paper, a dormitory air source heat pump hot water system in a college in Guangzhou as an object, the direct heating type air source heat pump hot water system operating performance were measured. The results show that under the condition of the average temperature of 23.27 ℃ and the average inlet temperature of 24.83 ℃, the average COP of the air source heat pump hot water system is about 3.67 and the COP of the unit is above 4.47, which has good operation performance and energy saving effect. However, During the supply and storage of hot water, there are still some problems to be solved in hot water systems mainly including pipes, valves and water tanks.
