In the present application, a hanging type air conditioner performs a refrigerating cycle of an indoor unit of the air conditioner by using a compressor, a condenser, an expansion valve, and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges refrigerant gas in a high-temperature and high-pressure state. 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 indoor heat exchanger 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 indoor heat exchanger may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioning indoor unit can adjust the temperature of the indoor space throughout the cycle. The outdoor unit of the air conditioner indoor unit refers to a portion of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner indoor unit 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 function as a condenser or an indoor heat exchanger.

Through the above scheme, when the split-type air seal is installed, the first split-type casing 700 and the second split-type casing 800 are directly sleeved with the connecting shaft 600, so that the limiting piece 500 is directly positioned between the first split-type casing 700 and the second split-type casing 800, the connecting shaft 600 is directly sleeved with the installation hole, and the limiting piece 500 does not need to pass through the installation hole, so that the aperture of the installation hole can be reduced, the possibility of leakage of air flow through the installation hole is reduced, and the tightness is improved.

In some embodiments, the scroll body further includes a second half-case 900, the second half-case 900 being disposed at a side of the first and second split cases 700 and 800 remote from the second fan 200, and a first receiving chamber being formed between the second half-case 900, the first and second split cases 700 and 800, and the first fan 300 being disposed in the first receiving chamber.

In some embodiments, the second half shell 900 is integrally formed with the second split shell 800.
