摘　　要：用空气焓差实验法,在制冷工况下对一台热泵型空调器进行最佳充注量的实验研究,同时,分别在制冷工况和制热工况下测量冷凝器和蒸发器管壁的温度分布。实验结果表明,空调系统中存在一个最佳制冷剂充注量,使得空调系统的制冷量和能效比达到最大值。根据实验结果,分别给出在制冷工况和制热工况下进行冷凝器和蒸发器换热计算时,制冷剂与管壁之间的平均温差。By using of air enthalpy difference method,tests the optimal refrigerant charge inventory in a heat pump air conditioner on refrigeration conditions.And measures the temperatures distributed on the walls of condenser and evaporator on refrigeration conditions and heating conditions respectively.The results show that there is an optimal refrigerant charge inventory in the air-conditioning system to maximize the refrigerating capacity and COP in it.Basing on experimental results,presents the mean temperatures between refrigerant and tube walls on refrigeration conditions and heating conditions to calculate the heat transfer of condenser and evaporator respectively.
