Cabinet air-conditioner indoor machine evaporation structure

Abstract

The present invention relates to an air conditioner technical field, especially a cabinet air-conditioner indoor machine evaporation structure, wherein the evaporator is disposed on the top of the conditioner shell and between the shell and the front panel. The evaporator is formed by a 'U-shape' copper pipe denting into uniformly arranged fins to be a integer with an arc upside and a straight tabular inferior, making full use of the unused space. The cabinet air-conditioner indoor machine evaporation improved structure of the invention increases the heat exchange area compared to the existing evaporator and advances the ability of the conditioner fast refrigeration/heating.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to the evaporator structure of an indoor unit of a cabinet type air conditioner. Background technique [0002] Generally speaking, an air conditioner is a refrigeration / heating device that keeps the indoor temperature at the temperature required by the user. The refrigerant circulating in its refrigeration system exchanges heat with the air flowing in the room to achieve indoor cooling or heating. People provide fresh and comfortable air environment. The refrigeration system of the air conditioner is mainly composed of an evaporator, a condenser, a compressor, and a throttling expansion device. [0003] In summer, the refrigerant in the refrigeration system performs a refrigeration cycle in the order of evaporation→compression→condensation→expansion to realize the cooling operation of the air conditioner; in winter, through the switching of the reversing valve, the refri...

Problems solved by technology

[0011] figure 1 , figure 2 , image 3 The evaporator 3 of the indoor unit of the cabinet type air conditioner shown in the prior art is a whole cuboid structure. When the evaporator is placed, it occupies a small space. There is a large amount of idle space in the cabinet machine, and the air sent by the centrifugal fan 4 flows through the evaporator. At 3 o'clock, only a small area of ​​cooling / heating can be carried out, that is to say, the entire cuboid structure of the evaporator in the indoor unit of the cabinet air conditioner of the prior art has a small area for heat exchange, and the cabinet has a large amount of idle space, which reduces the temperature of the air conditioner. Problems with rapid cooling / heating capabilities
