Abstract: By installing a set of water circulation air source heat pump heating system and a heat pipe type air source heat pump heating system on the user's site, the heating characteristics of the two heating systems are studied. The experimental results show that the power consumption of the heat pipe air source heat pump system is 4% less than that of the water cycle air source heat pump system when the outdoor ambient temperature is the same and the indoor temperature is the same; when the outdoor ambient temperature is the same, the indoor ambient temperature rises from 15℃ to 20℃, and the time consumption of the heat pipe air source heat pump system is only 37.5% of that of the water cycle air source heat pump system; when the outdoor ambient temperature is the same When the temperature of the indoor heat exchanger rises from 13.5℃ to 30℃, the time consumption of the heat pipe air source heat pump system is only 24.5% of that of the water circulation air source heat pump heating system; the operation analysis of defrosting is also carried out, which provides the experimental basis for the design of the heat pipe air source heat pump heating system.
