Air conditioner internal unit and air conditioner

Abstract

The invention provides an air conditioner internal unit and an air conditioner. The air conditioner internal unit comprises a shell (1), the shell (1) is provided with an upper air outlet (2) and a lower air outlet (3), and a main air inlet is further formed in the shell (1). The main air inlet is formed in a side plate of the shell (1), a first centrifugal fan (6) is disposed in the shell (1), and the first centrifugal fan (6) is a double air-outlet centrifugal fan. One air outlet of the first centrifugal fan (6) communicates with the upper air outlet, and the other air outlet of the first centrifugal fan (6) is in communication with the lower air outlet, and an air inlet of the first centrifugal fan (6) is in communication with the main air inlet. According to the air conditioner internal unit, the problem of air return in the air conditioner internal unit is avoided, and the air output is increased.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioner inner unit and an air conditioner. Background technique [0002] Traditional wall-mounted air conditioners have only one air inlet, outlet, and fan. Whether it is heating or cooling, the air comes out of one air outlet, and the comfort cannot achieve the best effect. Since there is only one air inlet and the air inlet area is limited, it is impossible to further increase the air intake and improve the heat exchange efficiency, and the heat exchange efficiency between the air blown by the air conditioner and the indoor air is seriously affected by the wind speed and the air output volume, and the wind speed and air volume cannot be further improved. Therefore, the heat exchange efficiency cannot be improved, thereby further improving the comfort. [0003] In the existing air conditioner, a kind of air conditioner with upper and lower air ou...

Problems solved by technology

[0002] Traditional wall-mounted air conditioners have only one air inlet, air outlet, and fan. Whether it is heating or cooling, the air comes out of one air outlet, and the comfort cannot achieve the best effect.

Since there is only one air inlet and the air inlet area is limited, it is impossible to further increase the air intake and improve the heat exchange efficiency, and the heat exchange efficiency between the air blown by the air conditioner and the indoor air is seriously affected by the wind speed and the air output volume, and the wind speed and air volume cannot be further improved. Improvement, so the heat transfer efficiency cannot be improved, thereby further improving the comfort

[0003] In the existing air conditioner, a kind of air conditioner with upper and lower air outlets is proposed. The air outlet of the air conditioner is located on the upper and lower sides, and the air inlet is located on the front panel. The distance between the air outlets is relatively short, so it is easy to cause the air from the air conditioner to enter the air conditioner directly from the air inlet on the front panel, causing the air return problem of the air conditioner, making the air volume unable to increase, and affecting the heating / cooling capacity of the air conditioner
