Abstract
The coupled system of cold water phase change machine and air source heat pump has advantages on heating and energy saving. To study the effect of different working conditions on energy consumption characteristics of the coupled system, taking a building of Qingdao as the research object and using simulation, the operation energy consumption and COP of the coupling system under the co-regulation of outdoor temperature and load side water supply temperature are analyzed. The heating performance of typical days is compared. The results show that when the control value of the outdoor temperature is 1℃, that of the minimum water supply temperature on the load side is 35.5℃, and the coupled control system is adopted, the total energy consumption in heating season and operating energy consumption in the coldest day are the lowest. Compared with the traditional air source heat pump system, the energy consumptions are reduced by 9.5% and 9.86% respectively, and the COPs of the system are increased by 22.53% and 54.2% respectively.
