Cabinet type air conditioner indoor unit

Abstract

The invention belongs to the technical field of air conditioning and specifically provides a cabinet type air conditioner indoor unit. The cabinet type air conditioner indoor unit comprises a unit body and a fresh air module. The unit body is provided with an air inlet and a first air outlet. The unit body is internally provided with an air supply fan, an evaporator and a water pan. The water panis arranged below the evaporator. The fresh air module is arranged below the unit body and is connected with the unit body. The fresh air module is provided with a suction port and an exhaust outlet.The suction port communicates with the outdoors through a pipe. The exhaust outlet communicates with the air inlet. The evaporator comprises a coil pipe. The coil pipe comprises a plurality of sectorstructures radial from the center to the periphery. The plurality of sector structures are distributed in the same plane in the circumferential direction. Through the arrangement, a coolant can radially flow along the coil pipe from the center of the evaporator to the periphery to enable air flow flowing through the evaporator to make full contact with the evaporator. Accordingly, the heat exchange effect of the evaporator can be improved, and then the cooling and heating effect of an air conditioner can be improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and specifically provides a cabinet type air conditioner indoor unit. Background technique [0002] As air conditioners are widely used in thousands of households, users have higher and higher requirements for the performance of air conditioners. Taking cabinet air conditioners as an example, usually under the same conditions, the performance of cabinet air conditioners depends on the heat transfer effect, and the heat transfer effect is directly related to the heat transfer area. The larger the heat transfer area, the better the heat transfer effect. high. [0003] Usually the structure and arrangement of the evaporator directly determine the size of the heat exchange area and the level of heat exchange effect. In existing cabinet-type air conditioners, the evaporator is usually placed obliquely in the air-conditioning shell or attached to the air inlet, but such an arrangement makes ...
