摘要
Abstract
Acombined solar air-source heat pump water heating system was developed. Experiments using this system in the hot summer and warm winter zone of Guangzhou during the winter,under three conditions of high irradiation、medium and low irradiation. According to hot water demand for low-rise building users to make experimental study on day-parting hot water supplyby simulating the user hot water usage. Experimental results showed that the air source heat pumps provide more heat than solar energy systems,especially when solar irradiance is low or without solarradiation when actual use of hot water. Under three different conditions,the daily solar energy guarantee rates is 28.22%,11.2% and 0,the daily average COP of the heat pump unit is 5.17,5.48 and 5.1,and the average COP of the composite system is 6.47,5.9 and 5.03.The system can fully coupling various working modes under different working conditions,and meet the demand of hot water efficiently and stably in winter,and the COP of composite system is significantly higher than that of heat pump COP while solar radiation be used.关键词
