Indoor unit of cabinet air conditioner

Abstract

The invention relates to the technical field of air conditioning, in particular to an indoor unit of a cabinet air conditioner. The indoor unit of the cabinet air conditioner comprises a body and a fresh air module. An air inlet and a first air outlet are arranged on the body, an air supply fan, a heat exchanger, a water pan and a sterilization and purification module are arranged in the body, thewater pan is arranged below the heat exchanger, and the sterilization and purification module is arranged at the air inlet. The fresh air module is arranged on the lower portion of the body and connected with the body, a suction opening and an exhaust opening are arranged on the fresh air module, the suction opening communicates with the outdoor space through a pipeline, and the exhaust opening communicates with the air inlet. The heat exchanger comprises a coiled pipe, the coiled pipe is arranged to be of a barrel-shaped structure in a surrounding manner, and one end of the barrel-shaped structure is closed. The coiled pipe of the heat exchanger is arranged to be of the barrel-shaped structure in the surrounding manner, one end of the barrel-shaped structure is closed, airflow must flowthrough the side of the barrel-shaped structure when flowing through the heat exchanger, airflow and the coiled pipe can be subjected to sufficient and uniform heat exchange, and therefore the heat exchange effect of the heat exchanger is improved.

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 heat exchanger directly determine the size of the heat exchange area and the heat exchange efficiency. In the existing cabinet air conditioners, the heat exchanger is usually placed obliquely in the air conditioner shell or attached to the air inlet, and the coils are arr...
