The key parameters monitoring system for system energy consumption, supply and return water temperature, water flowrate and indoor temperature is established. Based on the monitoring system, the indoor temperature and environmental temperature of the demonstration house are analyzed, and the total heat supply, total energy consumption, the heating season performance coefficient and operating performance under low environmental temperature of R32 air-source heat pump system are calculated and analyzed. The conclusions indicate that: R32 air-source heat pump has better heating effect, operation reliability and economy, the heating season performance coefficient is 3.05, the average indoor temperature is 18.1℃, the operating cost is 15.52RMB/m2, and when the environmental temperature is -20℃, the water supply temperature is 31℃ and the average system
