低温空气源热泵热风机分散采暖分析

Study on distributed heating of low temperature air source heat pump hot air blower

近年来,低温空气源热泵热风机(以下简称“热风机”)在北方清洁分散供暖中得到广泛应用。针对北方农村典型房屋冬季采用热风机采暖工况进行了数值模拟及实验研究,通过室内的温度场、速度场探讨了热风机对室内环境的影响。研究结果表明,采用数值模拟方法及实验研究方法得热风机室内温度均达16℃以上,室内整体风速人体感觉较为舒适,热风机适合在北方寒冷的分散式供热农村地区推广应用。

The CFD numerical simulation and actual data analysis were used to analyze the air temperature field,velocity field of the low temperature air source heat pump hot air blower(hereinafter referred to as“hot air blower”)in the winter working condition of a type of houses in the north of China.The research results show that the indoor temperature of the hot air blower is more than 16℃by numerical simulation method and experimental research method.The human body feels more comfortable and the overall wind speed in the room.The hot air blower is suitable for popularization and application in the cold distributed rural heating area in the north.
