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 cabinet type air conditioner indoor unit aims at solving the problemthat 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 body and a fresh air module, wherein an air inlet and a first air outlet are formed in the body; an air supply fan, the evaporator, a water pan and a sterilization and purification module are arranged in the body; the water pan isarranged below the evaporator; and the sterilization and purification module is arranged at the air inlet; the fresh air module is arranged below the body and is connected with the body; an air suction port and an exhaust outlet are formed in the fresh air module; the air suction port communicates with the outside through a pipeline; the exhaust outlet communicates with the air inlet; the evaporator comprises coil pipes and fins arranged on the coil pipes; the center lines of the coil pipes are positioned in the same horizontal plane and are spirally wound. According to the arrangement mode,when a cabinet type air conditioner runs, a refrigerant flows in the spiral direction, so that 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. Taking 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 level of heat exchange efficiency. In the existing cabinet air conditioners, the evaporator is usually placed obliquely in the air conditioner casing or attached to the air inlet, and the coils are ...
