Wherein, heat exchanger and fan all set up in the casing, and the casing can play the cover to heat exchanger and fan like this and establish the guard action, can prevent that external foreign matter from corroding to and the striking of external force leads to the damage of heat exchanger and fan structure, thereby can promote the structural reliability of heat exchanger and fan, can promote the structural reliability of air conditioner, guarantee that the air conditioner can normally work.
Further, be provided with heat transfer air intake and heat transfer air outlet on the casing, the air conditioner during operation, can pass through the operation of fan with the outside air current of casing in the heat transfer air intake introduces the casing, then form the heat transfer air current via the heat exchanger heat transfer, and the heat transfer air current can further be under the drive of fan, through heat transfer air outlet to the outside output of casing, thereby can make the air conditioner to the suitable wind of indoor transport temperature, realize the conditioning action of air conditioner to indoor temperature, guarantee the normal operating of air conditioner, satisfy user's user demand.
Specifically, the air conditioner of the present application is used in combination with an outdoor unit, wherein the heat exchanger may be an evaporator or a condenser, and the heat exchanger in the outdoor unit is a condenser or an evaporator, and the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, an expansion valve, a condenser, 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.

and controlling the remote controller to send a failure instruction to a user.
5. The air conditioner of claim 3, wherein the controller is configured to: and controlling a display of the air conditioner to send a failure instruction.
6. The air conditioner of claim 3, wherein the controller is configured to: and controlling the mobile phone software of the air conditioner to send a failure instruction.
7. The air conditioner of claim 1, wherein the controller is further configured to:
judging the accumulated working time of the wet film;
and when the accumulated working time of the wet film reaches the preset working time, judging whether the difference between the air outlet mouth moisture content of the fresh air pipe and the outdoor moisture content and the difference between the preset moisture content increase value exceed a preset range.
8. A method for detecting the failure of a wet film of an air conditioner is characterized by comprising the following steps:
the air conditioner is started, outdoor moisture content and a preset moisture content increase value are obtained according to the outdoor temperature and the outdoor humidity, and the moisture content of the fresh air duct air outlet mouth is obtained according to the fresh air duct air outlet humidity and the fresh air duct air outlet temperature;
judging whether the difference between the moisture content of the air outlet mouth of the fresh air pipe and the outdoor moisture content and the difference between the preset moisture content increase values exceed a preset range or not;
and when the difference between the moisture content of the air outlet mouth of the fresh air pipe and the outdoor moisture content and the difference between the preset moisture content exceed a preset range, judging that the wet film is invalid.
9. The method of claim 8, wherein the determining whether the difference between the humidity content of the fresh air duct and the outdoor humidity content and the preset humidity content increase value exceeds a preset range further comprises:
acquiring the moisture content increased after the outdoor fresh air is humidified by the wet film according to the difference between the moisture content of the fresh air pipe air outlet mouth and the outdoor moisture content;
judging whether the difference between the increased moisture content of the outdoor fresh air after being humidified by the wet film and the preset moisture content increase value exceeds a preset range or not;
and when the difference between the increased moisture content of the outdoor fresh air after being humidified by the wet film and the preset moisture content increase value exceeds a preset range, judging that the wet film is invalid.
10. The method for detecting wet film failure of an air conditioner according to claim 8, wherein before determining whether the difference between the moisture content of the fresh air duct and the outdoor moisture content and the preset moisture content increase value exceeds a preset range, the method further comprises:
judging the accumulated working time of the wet film;
and when the accumulated working time of the wet film reaches the preset working time, judging whether the difference between the moisture content of the air outlet mouth of the fresh air pipe and the outdoor moisture content and the difference between the preset moisture content increase values exceed a preset range.
