Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

The 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 outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

An air conditioner indoor unit 10 according to an embodiment of the present invention will be described with reference to fig. 1 to 4. The air conditioner indoor unit 10 may be a wall-mounted air conditioner indoor unit. In the following description of the present application, the air conditioner indoor unit 10 is exemplified as a wall-mounted air conditioner indoor unit. Of course, the air conditioner indoor unit 10 may be other types of air conditioner indoor units, and is not limited to a wall-mounted air conditioner indoor unit. Alternatively, the indoor unit 10 of the air conditioner may be a single-unit refrigerator or a heating and cooling machine.

As shown in fig. 1 to 4, an air conditioner indoor unit 10, such as a wall-mounted air conditioner indoor unit, according to an embodiment of the present invention includes a machine body 1 and a fresh air module 2.

Specifically, referring to fig. 1, the front surface 11 of the body 1 is formed with at least one air outlet 111, where "the front surface 11" refers to a side surface of the body 1 facing a user. Referring to fig. 1 and 3, the fresh air module 2 is provided on the machine body 1.
