摘　　要：针对某1.5 HP房间空调器降本机型开发过程中,制冷剂由R32更改为R410A,凝露工况下,室内机风道内左侧有小水珠汇成大水珠并滴落的问题,进行理论分析和实验验证,结果表明,相同蒸发器分流流路,采用不同的制冷剂,分流均匀性不同;在不改变量产机型室内机蒸发器分流流路的情况下,可通过降低目标排气温度,以增加系统运行时电子膨胀阀开度的方法,增加系统中R410A制冷剂的循环量,以降低蒸发器入口干度来提高室内机蒸发器分流均匀性,从而有效解决凝露问题。研究为解决实际工程中的类似问题提供了可行方案,对后续降本开发过程中制冷剂更改和系统优化起到一定的指导作用。In the process of developing a 1.5 HP room air conditioner,the refrigerant was changed from R32 to R410A.Under the condensation condition,there were small water droplets on the left side of the air duct of the indoor unit,which formed into large water droplets and drips.The theoretical analysis and experimental verification showed that the same evaporator diverting flow path,using different refrigerant,diverting uniformity was different.In the case of not changing the diverting flow path of the indoor evaporator of the mass production model,the circulation amount of R410A refrigerant in the system can be increased by reducing the target exhaust temperature to increase the opening of the electronic expansion valve during the system operation,and the uniformity of the diverting flow of the indoor evaporator can be improved by reducing the dryness of the evaporator inlet,so as to effectively solve the condensation problem.The research provides a feasible solution for solving similar problems in practical engineering,and plays a certain guiding role for refrigerant change and system optimization in the subsequent development process of cost reduction.
