It is beneficial to improve the cooling effect in the room, thereby ensuring the user experience.
如图1所示,作为本实施例提供的上述空调系统的一种优选的实施方式,空调系统还包括四通换向阀8;制冷时压缩机1的冷媒出口通过四通换向阀8与室外换热器31的第一端连通,压缩机1的冷媒进口通过四通换向阀8与室内换热器41的第二端连通;制热时压缩机1的冷媒出口通过四通换向阀8与室内换热器41的第二端连通,压缩机1的冷媒进口通过四通换向阀8与室外换热器31的第一端连通。As shown in Figure 1, as a preferred implementation of the above-mentioned air-conditioning system provided by this embodiment, the air-conditioning system further includes a four-way reversing valve 8; during refrigeration, the refrigerant outlet of the compressor 1 is connected to the four-way reversing valve 8 The first end of the outdoor heat exchanger 31 is communicated, and the refrigerant inlet of the compressor 1 is communicated with the second end of the indoor heat exchanger 41 through the four-way reversing valve 8; the refrigerant outlet of the compressor 1 is commutated through the four-way during heating The valve 8 communicates with the second end of the indoor heat exchanger 41, and the refrigerant inlet of the compressor 1 communicates with the first end of the outdoor heat exchanger 31 through the four-way reversing valve 8.
示例性地,通过在空调中设置四通换向阀8,可以使空调进行制冷和制热模式的转换。空调制冷时,冷媒由室外换热器31(作冷凝器使用)流向室内换热器41(作蒸发器使用);空调制热时,冷媒由室内换热器41(作冷凝器使用)流向室外换热器31(作蒸发器使用)。Exemplarily, by providing a four-way reversing valve 8 in the air conditioner, the air conditioner can switch between cooling and heating modes. When the air conditioner is cooled, the refrigerant flows from the outdoor heat exchanger 31 (used as a condenser) to the indoor heat exchanger 41 (used as an evaporator); when the air conditioner is heating, the refrigerant flows from the indoor heat exchanger 41 (used as a condenser) to the outdoors Heat exchanger 31 (used as an evaporator).

After the outdoor fresh air enters the housing 51 from the fresh air inlet, it first undergoes the dehumidification effect of the dehumidification evaporator 53, and then dehumidification After the heating of the condenser 54 is discharged into the room through the fresh air outlet.
