摘要
主要研究了大学生的用热水规律及热泵热水系统的运行特性.采用控制变量法,分析了环境温度、热水温度对热泵热水机组能效比的影响;分析了土壤源热泵与空气源热泵混合的热水系统中,两种热泵的配合运行问题,以及承压保温水箱对热泵热水系统能耗及能效比的影响.结合大学生的实际用水规律、室外环境温度及峰谷分时电价,提出了学生宿舍空气源热泵热水系统的经济运行策略.
This paper mainly researches the rule of students＇ hot water consumption and the operation characteristics of heat pump water system, using the controlling variable method analyzes the influence of environment temperature and hot water temperature on the EER of heat pump hot water units, analyzes the cooperation operation problems of the ground-source heat pump and air source heat pump in the hot water system composed of these two pumps, and the influence of the pressure holding tank on the energy consumption and energy efficiency ratio of heat pump hot water system. Combining with the actual water consumption rule of college students, outdoor environment temperature and the peak-valley time-of-use tariff, paper puts forward the economical operation strategy of the air source heat pump system in student dormitory.
