Thermoelectric cooling system for super-cooling section of air-conditioner condenser

Abstract

The invention relates to a cooling system of an air-conditioner pipeline, in particular to a thermoelectric cooling system for the super-cooling section of an air-conditioner condenser. The thermoelectric cooling system comprises the condenser. The inlet end of the condenser is connected with a compressor through an exhaust pipe, the compressor is connected with an evaporator through a gas return pipe, the outlet end of the condenser is connected with a throttling device through a pipeline, the throttling device is connected with the evaporator through a pipeline, and therefore a circulation pipeline is formed. The thermoelectric cooling system is characterized in that a first-stage super-cooling pipe is arranged in the condenser and is connected with a second-stage super-cooling pipe arranged outside the condenser, the second-stage super-cooling pipe is connected with the throttling device through a pipeline and is arranged in a heat pipe heat exchanger, and cooling fins are arranged in the heat pipe heat exchanger. According to the invention, the cooling fins and the heat pipe heat exchanger are arranged for actively cooling the second-stage super-cooling pipe, and the shortcoming that poor heat exchange and different use environment temperature cause change of the super-cooling temperature and then influence the stability of heat exchange and the efficiency of heat exchange is overcome.

Description

technical field [0001] The invention relates to an air conditioner pipeline cooling system, in particular to a thermoelectric cooling system for the subcooling section of an air conditioner condenser. Background technique [0002] When the current processing air conditioner is working, firstly, the compressor generates high-temperature and high-pressure gas refrigerant. After passing through the outdoor unit condenser, the high-temperature and high-pressure gas refrigerant is condensed into a low-temperature and high-pressure liquid, and then directly enters the capillary tube for throttling. Then it enters the evaporator to evaporate, absorbs the heat of the ambient air, turns into a low-temperature and low-pressure gas refrigerant, and circulates into the compressor to work. [0003] Such a cycle has the disadvantage of low heat exchange efficiency because no further subcooling treatment is performed on the condensed low-temperature and high-pressure liquid refrigerant. ...

Problems solved by technology

[0005] After the subcooling tube is used for supercooling, although the heat exchange efficiency is improved to a certain extent, because the subcooling section is located in the lower part of the condenser, there is poor heat exchange, and the temperature of the subcooling degree varies due to different ambient temperatures, which affects the heat exchange. Stability, a defect that ultimately affects heat transfer efficiency
