Cabinet air conditioner indoor machine

Abstract

The invention belongs to the technical field of air conditioning, particularly provides a cabinet air conditioner indoor machine, and aims to solve the problems in a conventional cabinet air conditioner indoor machine that the heat exchanging effect of a heat exchanger is not ideal, and a fresh air device is not convenient to arrange. The cabinet air conditioner indoor machine comprises a machinebody and a fresh air module, wherein an air inlet and first air outlets are formed in the machine body; a wind transporting fan, a heat exchanger and a defrosting tray are arranged in the machine body; an air suction opening and an exhaust opening are formed in the fresh air module; the air suction opening communicates with the external environment through a pipeline; the exhaust opening communicates with the air inlet; the heat exchanger comprises a plurality of coil pipes arranged in parallel and fins each of which is arranged on the corresponding coil pipe; the inlet ends of the coil pipesare arranged in a gathering manner; the outlet ends of the coil pipes are arranged in a diffusion manner; the shape of the coil pipes is in the shape of a broken line; and the gathering ends and the diffusion ends of the coil pipes are not in the same plane. According to the cabinet air conditioner indoor machine disclosed by the invention, the structures are arranged, so that the heat exchangingeffect of the cabinet air conditioner indoor machine is effectively strengthened, and the fresh air device is smoothly and additionally arranged.

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...
