室外温度波动对空气源热泵辐射地板供暖的影响
Influence of outdoor temperature fluctuation on air-source heat pump radiant floor heating
摘要：
根据3组实测数据分析了空气源热泵用于寒冷地区（ⅡB）时的热特性。针对典型的辐射供暖地板，用数值计算方法对某示范工程的空气源热泵辐射地板供暖进行了传热过程计算，发现室温计算值和实测值吻合较好，说明由于地板有较大的热容量，采用这种系统室温稳定性可以得到保障。

Abstract：
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.
