Cabinet air conditioner indoor unit

Abstract

The invention belongs to the technical field of air conditioning, and particularly provides a cabinet air conditioner indoor unit. The problems are solved that a heat exchanger of an existing air conditioner indoor unit is not ideal in heat exchange effect, a fresh air device cannot be conveniently arranged, and the sterilizing effect is not good. The cabinet air conditioner indoor unit comprisesa machine body and a fresh air module. The machine body is provided with an air inlet and a first air outlet. An air supply draught fan, a heat exchanger, a water collecting plate and a sterilizing and purifying module are arranged in the machine body. The fresh air module is provided with an air suction opening communicated with the outdoor space and an exhaust opening communicated with the air inlet. The heat exchanger comprises a plurality of coiled pipes in parallel and fins on the coiled pipes. Inlet ends of the coiled pipes are gathered, the outlet ends are diffused, the coiled pipes areeach in a folding line shape, and the gathered ends and the diffused ends of the coiled pipes are not located in the same plane. Through the settings, the heat exchange effect and sterilizing effectof the cabinet air conditioner indoor unit are effectively enhanced, and a fresh air device is smoothly added.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and specifically provides a cabinet type air conditioner indoor unit. Background technique [0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment. In order to maintain a comfortable ambient temperature, air conditioners have become an essential device in people's lives. In recent years, with the increasingly mature air-conditioning technology, users have put forward higher and higher requirements for the comprehensive 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 more on the heat exchange efficiency, and the heat exchange efficiency is directly related to the heat exchange area; generally, the larger the heat exchange area , the higher the heat transfer effici...
