Abstract

Abstract: The experimental platform of air source heat pump direct floor radiant heating system is built, and its heating effect, operation energy efficiency and thermal storage effect are experimentally studied. The results show that the heating effect of the new system is good, and the indoor temperature can be stable at about 20℃ when the ambient temperature is above -10℃. When the outdoor temperature is 10℃, the system COP is 4.25, and when the outdoor temperature is -10℃, the COP can reach 3.65. At the same time, the thermal storage effect of the floor radiant heating system is good. The outdoor temperature is 0℃, and the indoor temperature can still be maintained above 12℃ within 120 min after shutdown.

Key words: Air source heat pump, Floor radiation, Energy efficiency, Thermal storage
