Abstract

The invention relates to the technical field of air conditioning, in particular to a cabinet type air conditioner indoor unit. By means of the cabinet type air conditioner indoor unit, the problem that an evaporator of an existing cabinet type air conditioner indoor unit is poor in heat exchanging effect is solved. The cabinet type air conditioner indoor unit comprises a unit body, wherein an airinlet and a first air outlet are formed in the unit body; an air supply fan, the evaporator, a water pan and a sterilization and purification module are arranged in the unit body; the water pan is arranged below the evaporator; the sterilization and purification module is arranged at the air inlet; the evaporator comprises a coiler and fans arranged on the coiler; and the central line of the coiler coils in a swirling shape from top to bottom surrounding a vertical axis. According the arrangement of the cabinet type air conditioner indoor unit, when a cabinet type air conditioner operates, refrigerant flows in a three-dimensional way along the directions of the swirl, and thus, when the air flows through the evaporator, the heat exchange is more uniform and the effect of heat exchange 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...
