Air-conditioning indoor unit

Abstract

The invention provides an air-conditioning indoor unit. The air-conditioning indoor unit comprises a top cover, a base and a heat exchanger, wherein the heat exchanger comprises a shell and a body; the shell is arranged between the top cover and the base; the body is arranged in the shell and provided with an upper radial branch, a lower radial branch and axial branches located between the upper radial branch and the lower radial branch; the body further comprises a first main pipe and a second main pipe; the first main pipe communicates with the lower radial branch, the second main pipe communicates with the upper radial branch, a passage is formed among the first main pipe, the lower radial branch, the axial branches, the upper radial branch and the second main pipe, and when a refrigerant flows in the passage, the heat exchanger generates and radiates cold or heat to adjust the temperature of an external environment. According to the scheme, the temperature of the external environment is adjusted in a radiation mode, no wind feeling is achieved, and the comfort level of a user is improved. The overall occupied size of the air-conditioning indoor unit is reduced, meanwhile, the technological process is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit. Background technique [0002] With the development of society and the continuous improvement of people's living standards, various air conditioning devices have become one of the indispensable electrical equipment in people's daily life. Various air conditioning devices can help people reach an adaptable temperature when the ambient temperature is too high or too low. Current air conditioner regulating devices mainly include various types of air conditioners and fans. [0003] Current air conditioners often use finned heat exchangers to exchange heat for air, but the finned heat exchangers have a large volume and high cost. In addition, the existing air conditioners rely on fans to supply air, the convective heat transfer coefficient of air flow is small, and the wind resistance is relatively large, resulting in high noise during operati...

[0003] Current air conditioners often use finned heat exchangers to exchange heat for air, but finned heat exchangers are large in size and high in cost

In addition, the existing air conditioners rely on fans to supply air, the convective heat transfer coefficient of air flow is small, and the wind resistance is relatively large, resulting in high noise during operation and uneven air supply. After that, users are prone to symptoms such as cold, fever, leg pain, joint pain, etc., which seriously affect the user's health and experience
