Research of Ventilating Performance in North China of Air-source Heat Pump Direct Radiant Floor Heating

In order to confirm the applicability of the air-source heat pump radiant floor heating system in north China,using building energy consumption analysis software Dest,the energy consumption simulation is hourly carry out on a high-rise residential building.Through economic feasibility analysis,comparing with the centralized heating coal-fired boiler,it is concluded that energy efficiency of direct floor heating system is higher and its efficiency increases with the increase of coal prices,the peak valley price can better reflect its economy.The economic area of the direct radiant floor system in north China is confirmed.
