Cabinet type air conditioner indoor unit

Abstract

The invention relates to the technical field of air conditioning, in particular to a cabinet type air conditioner indoor unit. The device aims to improve heat exchange effect of a cabinet type air conditioner indoor unit. The cabinet type air conditioner indoor unit comprises a machine body and a fresh air module, wherein an air inlet and a first air outlet are formed in the machine body; an air supply fan, an evaporator and a water pan are arranged in the machine body, and the water pan is arranged below the evaporator; the fresh air module is arranged below the machine body and is connectedwith the machine body; an air suction port and an air outlet are formed in the fresh air module; the air suction port communicates with the outside through a pipeline, and the air outlet communicateswith the air inlet; the evaporator comprises a coil pipe and fins arranged on the coil pipe; and the central lines of the coil pipe are located in the same horizontal plane and are spirally wound. According to the arrangement mode, when the cabinet type air conditioner runs, refrigerant flows in the spiral direction, so that heat exchange is more uniform when air flows through the evaporator; andheat 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...
