摘　　要：建立空气源热泵机组阵列模型,对蒸发器周围流场、温度场分布以及蒸发器风机吸风量、蒸发器翅片管换热器进口表面温度不均匀度等进行数值模拟。空气源热泵机组阵列中心区域易出现冷岛效应。适当增大机组间距,有利于缓解冷岛效应。对于被围墙包围的空气源热泵机组阵列,热泵机组宜采用整体架高的安装方式。The model of air-source heat pump unit array is established,and the flow field and temperature field distribution around the evaporator,as well as the air intake volume of evaporator fan and the unevenness of inlet surface temperature of evaporator finned tube heat exchanger are numerically simulated.The central area of the air-source heat pump unit array is prone to the cold island effect.Appropriately increasing the spacing between units is beneficial for alleviating the cold island effect.For the air-source heat pump unit array surrounded by a wall,it is advisable to install the heat pump units in an overall elevated manner.
