Problems solved by technology

[0004] 1. Simple structure, unable to improve heat transfer efficiency and energy efficiency ratio
[0005] 2. It is impossible to reduce the cost while ensuring the heat exchange efficiency and energy efficiency ratio, and it is difficult to balance the two
[0006] 3. For heat exchangers with multiple refrigerant flow paths, the design of each refrigerant flow path and the unreasonable relationship between the distribution of refrigerants in each path make the heat transfer uneven in each section of the heat exchanger, which affects the heat transfer efficiency and energy efficiency ratio

Abstract

The invention relates to an air conditioner indoor unit, comprising: a casing, a heat exchange device, and a fan assembly. The heat exchange device of the air conditioner indoor unit is arranged in the casing and is configured to exchange heat with the air flowing through it. The heat exchange device has multiple rows of refrigerant pipe groups arranged along the front and back directions of the air conditioner indoor unit, and each row of refrigerant pipes The groups are all formed by superimposing refrigerant pipes in an S-shaped bend along the vertical direction of the air-conditioning indoor unit. The heat exchange device of the present invention has a plurality of rows superimposed in an S-shape to form a refrigerant pipeline group, which prolongs the flow path of the refrigerant and improves the heat exchange efficiency and energy efficiency ratio of the heat exchange device.

Description

technical field [0001] The invention relates to air-conditioning technology, in particular to an air-conditioning indoor unit. Background technique [0002] The space type, wind field distribution, and tube layout design of the heat exchanger on the air conditioner are very important, which will directly affect the efficiency of convective heat exchange, thereby affecting the level of heat exchange. The space type is closely related to the wind field distribution and depends on the size of the air conditioner. There are various forms of air-conditioning heat exchangers, from the initial flat fins and corrugated fins to the later development of louver fins and slotted fins. The arrangement of tube rows is adjusted based on the distribution of the box wind field in order to obtain higher heat exchange efficiency. [0003] In recent years, due to fierce market competition, various air conditioner manufacturers have aimed to improve heat exchange efficiency and energy efficien...
