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 invention aims to solve the problem that an evaporator of an existingcabinet type air conditioner indoor unit is non-ideal in heat exchange effect. In order to achieve the aim, the cabinet type air conditioner 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 containing plate are arranged in the machine body; the water containing plate is arranged under the evaporator; the fresh air module is arranged under the machine body and is connected with the machine body; an air suction port and an exhaust outlet are formed in the fresh air module; the air suction port communicates with the outdoor through a pipeline; the exhaust outlet communicates with the air inlet; the evaporator comprises a coil pipe and fins arranged on the coil pipe; and a center line of the coil pipe is arranged in a way of swirly coiling from top to bottom around a vertical axis. Through the arrangement manner, when the cabinet type air conditioner runs, a refrigerant stereoscopically flows along the direction of a swirl, so that when air flows through the evaporator, heat is uniformly exchanged, and a 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. 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...
