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 to cool or heat an indoor space.

The low-temperature and low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas in a high-temperature and high-pressure state, and the compressed refrigerant gas is discharged. 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 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.

Under the condition that the third mounting part 1-31 is adjacently connected with the first mounting part 1-11 or the second mounting part 1-21, the third mounting part 1-31 is vertically stacked and connected with the first mounting part 1-11 or the second mounting part 1-21, and the end surface size of the third mounting part 1-31 is the same as that of the first mounting part 1-11 or that of the second mounting part 1-21; or the third mounting parts 1-31 are connected with the first mounting parts 1-11 or the second mounting parts 1-21 side by side from left to right, and the side dimension of the third mounting parts 1-31 is the same as that of the first mounting parts 1-11 or that of the second mounting parts 1-21.

That is to say, for different installation department, the mode of designing the continuous surface of two installation departments into the size samely, when with two installation departments butt joint and connect, because the surface size that the cooperation is connected is the same, can link together more firmly.

In another embodiment, for the heat exchange module, in order to meet the heat exchange requirement of the heat exchange portion, a fan needs to be correspondingly configured, and the fan may be configured in various manners, which are illustrated below.

In a first mode, each heat exchange module may be configured with an independent fan, that is, the first heat exchange module 1-1 further includes a first fan, and the first fan is arranged on one side of the first heat exchange portion 1-12; the second heat exchange module 1-2 further comprises a second fan, and the second fan is arranged on one side of the second heat exchange part; the third heat exchange module 1-3 further comprises a third fan, and the third fan is arranged on one side of the third heat exchange portion.

In the second mode, after different heat exchange modules are matched according to air conditioner products, a main fan can be configured on one side of the plurality of heat exchange modules, the main fan is arranged on the side of the first heat exchange parts 1-12, the second heat exchange parts 1-22 and the third heat exchange parts 1-32, and the ventilation and heat exchange requirements of the heat exchange parts in the working process are met through the single main fan.

In another embodiment, the mounting portion may be a frame structure, the mounting portion of the frame structure is mainly used for bearing the requirement of mounting the heat exchanging portion, and after matching the corresponding heat exchanging module, the mounting portion is assembled outside the mounting portion, and then is covered by an outer casing to form an integral structure.
