除湿模块5的新风进口可以设置在室外，以便室外新风进入除湿模块5中；除湿模块5的新风出口与室内连通，用于向室内提供除湿后的新风。空调系统的室外机中的室外风机32驱动产生风流，使室外换热器31与室外环境进行换热，来提高室外换热器31的换热效果。The fresh air inlet of the dehumidification module 5 can be arranged outdoors, so that the outdoor fresh air enters the dehumidification module 5; the fresh air outlet of the dehumidification module 5 is connected to the room and is used to provide dehumidified fresh air to the room. The outdoor fan 32 in the outdoor unit of the air conditioning system is driven to generate air flow, so that the outdoor heat exchanger 31 exchanges heat with the outdoor environment, so as to improve the heat exchange effect of the outdoor heat exchanger 31.
本实施例提供的空调系统，通过在制冷时将压缩机1的冷媒出口与室外换热器31的第一端连通，室外换热器31的第二端通过第一节流装置61与室内换热器41的第一端连通，室外换热器31的第二端通过第二节流装置62与除湿蒸发器53的冷媒进口连通，室内换热器41的第二端和除湿蒸发器53的冷媒出口均与压缩机1的冷媒进口连通。从而，使得空调系统中的除湿模块5与室内换热器41共用一台压缩机1，节约了空调的生产成本和占用空间，且在制冷状态下除湿时除湿蒸发器53还对新风起到降温作用，有利于提高室内的制冷效果，进而可以保证用户的使用体验。The air conditioning system provided by this embodiment communicates with the first end of the outdoor heat exchanger 31 through the refrigerant outlet of the compressor 1 during cooling, and the second end of the outdoor heat exchanger 31 exchanges with the indoor through the first throttling device 61 The first end of the heat exchanger 41 is in communication, the second end of the outdoor heat exchanger 31 is in communication with the refrigerant inlet of the dehumidification evaporator 53 through the second throttling device 62, and the second end of the indoor heat exchanger 41 is connected to the dehumidification evaporator 53 The refrigerant outlets are all connected with the refrigerant inlet of the compressor 1. Thereby, the dehumidification module 5 in the air conditioning system and the indoor heat exchanger 41 share a compressor 1, which saves the production cost and space of the air conditioner, and the dehumidification evaporator 53 also cools the fresh air when dehumidifying in the refrigeration state. 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).
如图2和图3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，除湿模块5还包括除湿冷凝器54，除湿冷凝器54设置于外壳51内，制热时室外新风由新风进口进入外壳51内并经过除湿蒸发器53和除湿冷凝器54后由新风出口流出。As shown in Figures 2 and 3, as a preferred implementation of the above-mentioned air conditioning system provided in this embodiment, the dehumidification module 5 further includes a dehumidification condenser 54 which is arranged in the housing 51 and is heated outdoors. The fresh air enters the housing 51 from the fresh air inlet, passes through the dehumidification evaporator 53 and the dehumidification condenser 54 and then flows out from the fresh air outlet.
示例性地，当空调可以在制冷模式和制热模式之间转换时，由于在除湿模块5的外壳51中同时设置除湿蒸发器53和除湿冷凝器54，制热时室外新风由新风进口进入外壳51内并经过除湿蒸发器53的除湿作用和除湿冷凝器54加热作用后由新风出口排到室内。如此，除湿模块5在对 新风进行除湿并进行加热后送入室内，降低了除湿作用对室内制热效果的不良影响。Exemplarily, when the air conditioner can switch between the cooling mode and the heating mode, since the dehumidification evaporator 53 and the dehumidification condenser 54 are provided in the housing 51 of the dehumidification module 5 at the same time, the outdoor fresh air enters the housing through the fresh air inlet during heating. 51 and after the dehumidification effect of the dehumidification evaporator 53 and the heating effect of the dehumidification condenser 54 are discharged into the room through the fresh air outlet. In this way, the dehumidification module 5 dehumidifies and heats the fresh air before sending it into the room, which reduces the adverse effect of dehumidification on the indoor heating effect.
如图2和图3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，除湿蒸发器53靠近新风进口设置，除湿冷凝器54靠近新风出口设置。As shown in Figs. 2 and 3, as a preferred embodiment of the above-mentioned air conditioning system provided by this embodiment, the dehumidification evaporator 53 is arranged close to the fresh air inlet, and the dehumidification condenser 54 is arranged close to the fresh air outlet.
示例性地，在空调制冷的情况下除湿模块5进行除湿时，除湿蒸发器53工作，除湿冷凝器54不工作，在对新风进行除湿的同时还有降温冷却的作用。Exemplarily, when the dehumidification module 5 performs dehumidification in the case of air conditioning and refrigeration, the dehumidification evaporator 53 works, and the dehumidification condenser 54 does not work, and it also has the function of cooling and cooling while dehumidifying the fresh air.
在空调制热的情况下除湿模块5进行除湿时，除湿蒸发器53和除湿冷凝器54同时工作，室外新风由新风进口进入外壳51内后，先经过除湿蒸发器53的除湿作用，再经过除湿冷凝器54的加热作用后由新风出口排到室内。如此，可以更有效的降低除湿作用对室内制热效果的不良影响。When the dehumidification module 5 performs dehumidification under the condition of air conditioning and heating, the dehumidification evaporator 53 and the dehumidification condenser 54 work at the same time. 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. In this way, the adverse effect of dehumidification on the indoor heating effect can be reduced more effectively.

For the dehumidification function, the circulation route of the refrigerant is: compressor 1→four-way change Directional valve 8 → outdoor heat exchanger 31 → first on-off valve 71 → second throttling device 62 → dehumidifier evaporator 53 → compressor 1; for the refrigeration function, the circulation route of the refrigerant is: compressor 1 → four-way exchange Directional valve 8→outdoor heat exchanger 31→first throttling device 61→indoor heat exchanger 41→four-way reversing valve 8→compressor 1.
在空调制热的情况下除湿模块5进行除湿时，第一通断阀71关闭，第二通断阀72打开，对于除湿功能，冷媒的循环路线为：压缩机1→第二通断阀72→除湿冷凝器54→第二节流装置62→除湿蒸发器53→压缩机1；对于制热功能，冷媒的循环路线为：压缩机1→四通换向阀8→室内换热器41→第一节流装置61→室外换热器31→四通换向阀8→压缩机1。When the dehumidification module 5 performs dehumidification in the case of air conditioning and heating, the first on-off valve 71 is closed, and the second on-off valve 72 is opened. For the dehumidification function, the circulation route of the refrigerant is: compressor 1 → second on-off valve 72 → Dehumidification condenser 54 → Second throttling device 62 → Dehumidification evaporator 53 → Compressor 1; for the heating function, the circulation route of the refrigerant is: compressor 1 → four-way reversing valve 8 → indoor heat exchanger 41 → The first throttle device 61→outdoor heat exchanger 31→four-way reversing valve 8→compressor 1.
