Abstract

The invention relates to the technical field of air conditioning, in particular to a cabinet air conditioner indoor unit. The cabinet air conditioner indoor unit aims at solving the problem that the heat exchange effect of an evaporator of an existing cabinet air conditioner indoor unit is not ideal. In order to solve the problem, the cabinet air conditioner indoor unit comprises a unit body and afresh air module. The unit body is provided with an air inlet and a first air outlet, and an air supply draught fan, an evaporator, a water collecting plate and a sterilizing and purifying module arearranged in the unit body. The water collecting plate is arranged below the evaporator, and the sterilizing and purifying module is arranged at the position of the air inlet. The fresh air module isarranged below the unit body and is connected with the unit body. The fresh air module is provided with an air suction opening and an exhaust opening, wherein the air suction opening communicates withthe outdoor part through a pipeline, and the exhaust opening communicates with the air inlet. The evaporator comprises a coil pipe and fins arranged on the coil pipe, and the center line of the coilpipe is arranged spirally around a vertical axis in a vortex shape from top to bottom.

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...
