OPERATION CHARACTERISTICS ANALYSIS OF PV/T COUPLED HEAT PUMP SYSTEM
摘要
Abstract
This paper constructs a PV/T coupled heat pump system based on a PV/T heat pump system for domestic hot water supply and a ground source air source heat pump heating system.Taking a three-story public building in Zhengzhou as the research object,the PV/T coupled heat pump system is compared with the PV/T heat pump system for domestic hot water supply and the ground source air source heat pump heating system in terms of surface temperature and power generation efficiency of PV/T components,heat collection,soil temperature changes,and seasonal coefficient of performance of ground source heat pumps.The effectiveness of the PV/T coupled heat pump system is verified.The analysis results show that:1)During the heating season,the average daily surface temperature of PV/T components in the PV/T coupled heat pump system decreased by 7.38℃compared to the PV/T heat pump system for supplying domestic hot water.During the non heating season,the average daily surface temperature of PV/T components in the PV/T coupled heat pump system decreased by 26.49℃compared to the PV/T heat pump system for supplying domestic hot water.The PV/T coupled heat pump system can effectively reduce the surface temperature of PV/T components.2)During the heating season and non heating season,the average daily power generation efficiency of the PV/T coupled heat pump system increased by 2.72%and 9.24%,respectively,compared to the PV/T heat pump system for domestic hot water supply.In the heating season and non heating season,compared to the PV/T-heat pump system for domestic hot water supply,the collection efficiency of the PV/T-coupled heat pump system has increased by 19.96%and 74.65%,respectively.3)In the case of a PV/T component area of 90 m2,with the increase of system operating years,the soil temperature of both the PV/T coupled heat pump system and the ground source air source heat pump heating system shows an overall downward trend.When using a PV/T coupled heat pump system with a PV/T component area of 180 m2,the soil temperature increases at a rate of 0.14℃per year for 20 years.Compared to the ground source air source heat pump heating system,the PV/T coupled heat pump system has increased the seasonal coefficient of performance of the ground source heat pump by 13.44%.关键词
