通过对湖南省湘潭市一空气源热泵机组在冬季易结霜的气候条件下运行参数进行测定,获得了夏热冬冷地区冬季空气源热泵运行的基础数据,结果表明:当室外换热器表面温度不大于0℃时,空气中的水分将在换热器表面凝结并结霜;随着开机时间的延长,霜层厚度不断增加,导致制热效果恶化。
通過對湖南省湘潭市一空氣源熱泵機組在鼕季易結霜的氣候條件下運行參數進行測定,穫得瞭夏熱鼕冷地區鼕季空氣源熱泵運行的基礎數據,結果錶明:噹室外換熱器錶麵溫度不大于0℃時,空氣中的水分將在換熱器錶麵凝結併結霜;隨著開機時間的延長,霜層厚度不斷增加,導緻製熱效果噁化。

According to testing operating parameters of an air source heat pump in easy frosting conditions in Xiangtan city of Hunan province, the basic data was obtained about operating parameters of air source heat pump in hot summer and cold winter area in winter. The results show that the moisture in the air will condensation and frost in the surface of the heat exchanger when the temperature of outdoor heat exchanger surface is below 0 ℃. Frost layer increases with the heat pump operating and lead to heat capacity decrease.
