An outdoor fan 32 in an 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, and the heat exchange effect of the outdoor heat exchanger 31 is improved.
In the air conditioning system provided in this embodiment, when cooling, the refrigerant outlet of the compressor 1 is communicated with the first end of the outdoor heat exchanger 31, the second end of the outdoor heat exchanger 31 is communicated with the first end of the indoor heat exchanger 41 through the first throttling device 61, the second end of the outdoor heat exchanger 31 is communicated 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 and the refrigerant outlet of the dehumidification evaporator 53 are both communicated with the refrigerant inlet of the compressor 1.

Illustratively, when the air conditioner can be switched between the cooling mode and the heating mode, because the dehumidifying evaporator 53 and the dehumidifying condenser 54 are arranged in the casing 51 of the dehumidifying module 5, outdoor fresh air enters the casing 51 through the fresh air inlet during heating and is exhausted to the indoor through the fresh air outlet after being subjected to the dehumidifying function of the dehumidifying evaporator 53 and the heating function of the dehumidifying condenser 54. So, dehumidification module 5 sends into indoorly after dehumidifying and heating the new trend, has reduced the harmful effects of dehumidification effect to indoor heating effect.
As shown in fig. 2 and 3, as a preferred embodiment of the air conditioning system provided in this embodiment, the dehumidifying evaporator 53 is disposed near the fresh air inlet, and the dehumidifying condenser 54 is disposed near the fresh air outlet.
For example, when the dehumidification module 5 performs dehumidification in the case of air-conditioning refrigeration, the dehumidification evaporator 53 is operated, the dehumidification condenser 54 is not operated, and the dehumidification and cooling effects are performed while dehumidifying fresh air.
When dehumidification module 5 dehumidifies under the condition that the air conditioner heats, dehumidification evaporimeter 53 and dehumidification condenser 54 simultaneous working, outdoor new trend gets into in the shell 51 by the new trend import back, passes through the dehumidification effect of dehumidification evaporimeter 53 earlier, discharges indoor by the new trend export after the heating effect of dehumidification condenser 54 again. Therefore, the adverse effect of the dehumidification effect on the indoor heating effect can be more effectively reduced.
As a preferred embodiment of the air conditioning system provided in this embodiment, a first end of the dehumidifying condenser 54 communicates with a first end of the dehumidifying evaporator 53 through a second throttling device 62, and a second end of the dehumidifying condenser 54 communicates with a refrigerant outlet of the compressor 1; a first on-off valve 71 is further provided in a flow path between the second throttling device 62 and the second end of the outdoor heat exchanger 31, and a second on-off valve 72 is further provided in a flow path between the second end of the dehumidifying condenser 54 and the refrigerant outlet of the compressor 1.
For example, when the dehumidification module 5 performs dehumidification in the case of air-conditioning cooling, the first on-off valve 71 is opened and the second on-off valve 72 is closed, and for the dehumidification function, the circulation route of the refrigerant is: compressor 1 → four-way selector valve 8 → outdoor heat exchanger 31 → first on-off valve 71 → second throttling device 62 → dehumidification evaporator 53 → compressor 1; for the refrigeration function, the circulation route of the refrigerant is as follows: compressor 1 → four-way selector valve 8 → outdoor heat exchanger 31 → first throttle device 61 → indoor heat exchanger 41 → four-way selector valve 8 → compressor 1.
When the dehumidification module 5 performs dehumidification in the case of air-conditioning heating, the first on-off valve 71 is closed and the second on-off valve 72 is opened, and for the dehumidification function, the circulation route of the refrigerant is: compressor 1 → second cut-off valve 72 → dehumidifying condenser 54 → second throttling device 62 → dehumidifying evaporator 53 → compressor 1; for the heating function, the circulation route of the refrigerant is as follows: compressor 1 → four-way selector valve 8 → indoor heat exchanger 41 → first throttle device 61 → outdoor heat exchanger 31 → four-way selector valve 8 → compressor 1.
The switching of the heating and cooling functions of the air conditioning system of the present embodiment is realized by switching the four-way valve, and the switching of the dehumidification mode in the heating and cooling states is realized by the first on-off valve 71 and the second on-off valve 72, wherein the first on-off valve 71 and the second on-off valve 72 may be selected as electromagnetic valves, so as to conveniently realize the control of the air conditioning system.
As shown in fig. 1, as a preferred embodiment of the air conditioning system provided in the present embodiment, an indoor heat exchanger 41 is disposed in an indoor unit casing 51 of the air conditioning system; the indoor unit shell 51 is provided with a first air inlet and an air outlet, and an indoor fan 42 of the air conditioning system drives indoor air to enter the indoor unit shell 51 from the first air inlet and to be discharged from the air outlet after passing through the indoor heat exchanger 41; the indoor unit casing 51 is further provided with a second air inlet, the second air inlet is communicated with the air outlet, and the fresh air outlet is in butt joint with the second air inlet.
For example, in the air conditioning system in this embodiment, when in operation, indoor air enters the indoor unit housing 51 from the first air inlet to exchange heat with the indoor heat exchanger 41, and then is discharged indoors from the air outlet, so as to adjust the indoor temperature; meanwhile, the fresh air enters the indoor unit shell 51 from the second air inlet after being dehumidified by the dehumidification module 5 and then is discharged indoors from the air outlet, so that the purpose of providing the fresh air indoors is achieved.
As a preferred embodiment of the air conditioning system provided in this embodiment, a regulating valve (not shown in the figure) is disposed between the fresh air outlet and the second air inlet of the air conditioning system.
For example, the amount of fresh air entering the room from the dehumidification module 5 can be adjusted by an adjusting valve, and whether to start the fresh air function is controlled by the adjusting valve.
