Influence of outdoor temperature fluctuation on air-source heat pump radiant floor heating

According to three group testing data, analyses thermal characteristics of the air-source heat pump applied to cold zone （ⅡB）. Based on the typical radiant heating floor, calculates the heat transfer performance of the air-source heat pump radiant floor heating for a demonstration project using numerical calculation method, and the calculation values are coincident with the testing data, which indicates that the stability of indoor temperature can be guaranteed because of the large thermal capacity of the floor.
