Abstract
To increase the heating stability and system energy efficiency as well as to offer technical assistance for promoting and deploying multi-energy coupled heating technology in village and township buildings, a solar-air source coupled heating system is suggested and developed. The experiment was conducted on a multi-energy coupled heating system for a village and town office building in Hun nan New Area, Shenyang City, over a period of 15 days, with an average daily solar radiation intensity of 558.62 w/m2-h and an average outdoor temperature ranging from -18.3 °C to -2.7 °C. The trial findings demonstrated that all indoor temperatures could exceed 18 °C while the system was in use, and the average value of the system’s overall energy efficiency was 2.45.
