Detailed Description
The present invention is specifically described below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.
In the present application, an air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The fan 30 may be a cross flow fan.
In some embodiments of the present application, referring to fig. 7 and 8, the fresh air module 40 is disposed within the housing 10 at one end of the heat exchanger 20. The fresh air outlet 414 is arranged on the side surface of the fresh air module 40 close to the heat exchanger 20, and the fresh air outlet 414 faces the air-conditioning air duct 50, so that fresh air introduced by the fresh air module 40 can enter the air-conditioning air duct 50 through the fresh air outlet 414.
The fresh air module 40 in the prior art generally uses a centrifugal fan, and fresh air can only be discharged from the circumferential direction of the fresh air shell 41 and cannot be discharged from the side face. The fan 42 of the present application adopts an axial fan, and the axial direction of the axial fan can discharge air, so that the side surface of the fresh air module 40 close to the heat exchanger 20 can discharge air, and the fresh air is directly blown into the air-conditioning duct 50; and moreover, the axial flow fan can reduce the space occupied by the air conditioner indoor unit in the length direction, so that the whole size of the air conditioner indoor unit is more compact.
In some embodiments of the present application, referring to fig. 4, 6, the fresh air outlet 414 includes a first fresh air outlet 415 and a second fresh air outlet 416; the first fresh air outlet 415 is communicated with the air inlet duct 51, and the second fresh air outlet 416 is communicated with the air outlet duct 52.

Referring to fig. 4, the fresh air module 40 may include an air outlet portion 417. The air outlet portion 417 is used to guide outdoor fresh air blown out from the fan 42.
The air outlet portion 417 may include a first air outlet portion 418 and a second air outlet portion 419.
Referring to fig. 7, the first air outlet portion 418 extends from the side of the fresh air housing 41 toward the heat exchanger 20, the first air outlet portion 418 is hollow to form a flow path of fresh air, the first fresh air outlet 415 is formed at an end of the first air outlet portion 418, and the fresh air flowing through the first air outlet portion 418 can be discharged into the intake air duct 51 through the first fresh air outlet 415.
Referring to fig. 8, the second air outlet portion 419 extends from the side of the fresh air housing 41 toward the heat exchanger 20, the second air outlet portion 419 is hollow to form a flow path of fresh air, the second fresh air outlet 416 is formed at an end of the second air outlet portion 419, and the fresh air flowing in the second air outlet portion 419 can be discharged into the air outlet duct 52 through the second fresh air outlet 416.

Since the air inlet duct 51 is located above the air outlet duct 52, correspondingly, the first fresh air outlet 415 is located above the second fresh air outlet 416.
The first air outlet portion 418 and the second air outlet portion 419 are substantially rectangular parallelepiped shapes in the present embodiment. However, in other embodiments, the first air outlet portion 418 and the second air outlet portion 419 may have other shapes.
In some embodiments of the present disclosure, the first fresh air outlet 415 and the second fresh air outlet 416 are respectively provided with an air valve (not shown), and the fresh air outlet 414 can be opened or closed by the air valves, so as to control the opening and closing of the first fresh air outlet 415 and the second fresh air outlet 416.
When the air valve at the first fresh air outlet 415 is opened, the fresh air blown out from the fan 42 flows in the first air outlet portion 418 and blows towards the air inlet duct 51, the fresh air flows into the air outlet duct 52 after passing through the heat exchanger 20 together with the air-conditioning air in the air inlet duct 51 for heat exchange, and finally is discharged to the indoor through the air outlet 12.
