Abstract

The invention relates to the technical field of air conditioning, in particular to a cabinet-type air-conditioning indoor unit. The invention aims at solving the problem that an evaporator of an existing cabinet-type air-conditioning indoor unit does not have an ideal heat exchange effect. To achieve the aim, the cabinet-type air-conditioning 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, and internally provided with an air feeding draught fan, an evaporator and a water collection disc, and the water collection discis arranged below the evaporator; the fresh air module is arranged below the unit body and connected with the unit body, the fresh air module is provided with air suction port and an air exhaust port, the air suction port is communicated with the outside through a pipeline, and the air exhaust port is communicated with the air inlet. The evaporator comprises multiple layers of heat exchange assemblies and fins arranged on each layer of heat exchange assemblies, and any two layers of the heat exchange assemblies are connected through a first connecting pipe. Through the arrangement mode, a refrigerant flows among multiple layers of the heat exchange assemblies, thus when air flows through the evaporator, eat exchange is more uniform, and the heat exchange effect is better.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to 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. Take the cabinet air conditioner as an example. Usually under the same conditions, the performance of the cabinet air conditioner depends on the heat exchange efficiency, and the heat exchange efficiency is directly related to the heat exchange area. The larger the heat exchange area, the higher the heat exchange efficiency. high. [0003] Usually, the structure and arrangement of the evaporator directly determine the size of the heat exchange area and the heat exchange efficiency. In existing cabinet-type air conditioners, the evaporator is usually placed obliquely inside the air conditioner casing or attached to the air inlet, and the coils are arran...
