变频空调制冷系统组成
变频空调由压缩机、蒸发器、冷凝器、电磁四通阀、电子膨胀阀、除霜阀、双毛细管等部件组成，工作时，空调器根据空调房间的需要，自动控制变频器输出频率较高的交流电，使电动机的转速加快，压缩机的制冷量加大，达到快速制冷或制热的目的，相反，当房间的制冷或制热量较小时，压缩机以正常速度或较低速度运转，因此，变频空调具有连续的制冷量调节，使得房间的温度波动较小。
在压缩机工作过程中，微电脑系统控制变频压缩机的同时，控制电子膨胀阀的开启度，保持适当的制冷剂流量，从而直接改变蒸发器中制冷剂的流量使其状态发生改变，压缩机的转速与膨胀阀的开启度相对应，压缩机的排气量与膨胀阀的供液量相对应，使过热度不至于太大，使蒸发器的能力得到高大限度的发挥，从而使制冷系统实现比较高效率的控制。
Inverter air conditioning refrigeration system
The inverter air conditioner is composed of a compressor, an evaporator, a condenser, an electromagnetic four-way valve, an electronic expansion valve, a defrost valve, a double capillary tube and the like. When working, the air conditioner automatically controls the output frequency of the inverter according to the needs of the air-conditioned room. The alternating current speeds up the speed of the electric motor, and the cooling capacity of the compressor is increased to achieve the purpose of rapid cooling or heating. On the contrary, when the cooling or heating capacity of the room is small, the compressor runs at normal speed or lower speed, so The inverter air conditioner has continuous cooling capacity adjustment, which makes the room temperature fluctuation less.
During the operation of the compressor, the microcomputer system controls the inverter compressor while controlling the opening degree of the electronic expansion valve to maintain an appropriate refrigerant flow rate, thereby directly changing the flow rate of the refrigerant in the evaporator to change its state. The rotation speed corresponds to the opening degree of the expansion valve, and the displacement of the compressor corresponds to the liquid supply amount of the expansion valve, so that the superheat degree is not too large, so that the capacity of the evaporator is maximized, thereby realizing the refrigeration system. The most efficient control.
