基于自动蓄/放热装置的多曲面聚光集热空气源热泵系统实验研究
Experimental study on air source heat pump heating system based on automatic heat storage/discharge device with compound multi-surface concentrator
摘要
Abstract
In order to achieve clean heating in northern rural areas,this paper constructs an air source heat pump heating system based on automatic heat storage/discharge devices and compound multi-surface concentrating collectors.Experimental research shows that:at the same water supply temperature,the COP of the heat pump increases gradually with the increase of the inlet air temperature of the evaporator and the intensity of solar radiation.When the heat collector and heat pump are operated together,the heat storage device can automatically store heat and automatically supplement the heat of the air entering the evaporator.The temperature rise of the air is 2~4℃.The system heat collection and heating capacity on the experimental day were 2.29 MJ/m2 and 27.99 MJ/m2 respectively,the system energy efficiency ratio(SEER)was 1.84,and the daily average solar energy contribution rate was 41.2%.When the air source heat pump operates alone,the heating capacity of the heat pump on the experimental day is 8.75 MJ/m2,and the SEER is 1.79.The above results show that the solar subsystem constructed in this article can automatically adjust the heat storage of the system and the heat supplement to the evaporator,improve the energy efficiency ratio of the system,reduce the difficulty of operation and maintenance,and has certain adaptability in rural areas.关键词
