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

The second mounting beam 6 is provided at the junction of the left side plate and the front panel 13 for the fixed connection between the panels and the function of supporting the housing 1, enhancing the structural stability of the housing 1 in the up-down direction.

The heat exchanger may be disposed in the intake air passage and on a side of the intake air passage near the intake opening 11. The heat exchanger serves to absorb heat from or transfer heat to air introduced into the intake port 11.

Heat exchanger 2 is for air inlet space and air-out space with 1 internal partitioning of casing, and the air flows through heat exchanger 2 to air-out space after entering into air inlet space by air intake 11, and the air that flows through to the air-out space is discharged by air outlet 12.

One side of the heat exchanger 2 is provided with a water pan, and when the air conditioner indoor unit of the embodiment is installed and arranged up and down, the water pan can be arranged below the heat exchanger to collect the condensed moisture in the heat exchanger.
