Ducted air conditioner and air conditioner

Abstract

The invention provides a ducted air conditioner and an air conditioner, and relates to the technical field of air conditioners. The air supply effect is guaranteed, meanwhile, the occupied space of the ducted air conditioner can be reduced, and noise can be lowered. The ducted air conditioner comprises a shell, at least one turbofan and a heat exchanger. The shell comprises a top face, the top face is used for being connected with an indoor ceiling, and an air return opening and an air outlet are formed in the shell. The turbofans are arranged in the shell, and rotary shafts of the turbofans are perpendicular to the top face of the shell. The heat exchanger is arranged in the shell and located among the turbofans and the air outlet. The ducted air conditioner is used for the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air duct machine and an air conditioner. Background technique [0002] Duct unit is the abbreviation of hidden air conditioner. It is generally installed in the ceiling of the room. Compared with the general wall-mounted indoor unit, the duct unit is hidden in the ceiling and is more beautiful. Therefore, it is more and more widely used. At present, refer to figure 1 , a general air duct machine includes a casing 100 and a fan 200 and a heat exchanger 300 located in the casing 100. The casing 100 is provided with an air outlet 101 and a return air outlet 102. Under the action of the fan 200, the air from the return air outlet 102 enters the casing 100, passes through the heat exchanger 300 for heat exchange, and then is sent out from the air outlet 101 to achieve cooling or heating. The arrows in the figure indicate the airflow direction. [0003] In the prior art, ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in order to ensure the air supply effect and reduce the noise, it is necessary to increase the diameter of the fan 200, which requires a corresponding increase in the thickness of the casing 100, but the distance between the indoor suspended ceiling 400 and the ceiling 500 is limited, and the air duct machine It is located between 400 and 500 of the indoor suspended ceiling. Among the existing air duct machines, cross-flow fans or double-suction forward multi-blade centrifugal fans are usually used. The radial size is small and the axial size is large. The air duct machine After installation, the rotating shaft of the fan 200 in the casing 100 is parallel to the indoor ceiling 500, the diameter of the fan 200 is strictly limited by the thickness of the casing 100, and the thickness of the casing 100 is limited by the distance between the suspended ceiling 400 and the ceiling 500 , so that how to reduce the occupied space of the air duct machine while ensuring the air supply effect has become a technical problem to be solved urgently
