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 plurality of second protrusions 3412 on each guide portion 341 are opposed to the bottom wall of the corresponding slide groove 311. When the two guide portions 341 move up and down in the two sliding grooves 311, the plurality of second protrusions 3412 of each guide portion 341 may contact the bottom wall of the corresponding sliding groove 311, and the side surfaces of the guide portion 341 may be prevented from contacting the entire bottom wall of the corresponding sliding groove 311. Thus, by providing the plurality of second protrusions 3412, the plurality of second protrusions 3412 can be brought into contact with the sliding grooves 311, so that the frictional force between the guide portions 341 and the sliding grooves 311 can be further reduced when the moving member 34 moves up and down with respect to the mounting member 31, thereby preventing generation of abnormal noise in movement.
