Abstract

The invention relates to the technical field of air conditioning, in particular to a cabinet type air conditioner indoor unit, and aims to solve the problem that an evaporator of an existing cabinet type air conditioner indoor unit is not ideal in heat exchange effect. The cabinet type air conditioner indoor unit comprises a machine body, wherein an air inlet and a first air outlet are formed in the machine body; an air supply fan, an evaporator, a water pan and a sterilization and purification module are arranged in the machine body; the water pan is arranged below the evaporator, and the sterilization and purification module is arranged at the air inlet; the evaporator comprises coilers, and fins arranged on the coilers; and the center lines of the coilers are positioned in the same horizontal plane and are spirally wound. By means of the arrangement mode, when a cabinet type air conditioner runs, refrigerant flows in the spiral direction, so that when air flows through the evaporator, the heat 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...
