Car air conditioning system

Abstract

The invention provides a car air conditioning system. The car air conditioning system is characterized by comprising a power supply, a semiconductor hot and cold exchanger, an air blower, a first copper pipe, a second copper pipe, a third copper pipe, a first check valve, a second check valve, a third check valve and a control part, wherein the power supply is used for supplying powder for the car air conditioning system; the semiconductor hot and cold exchanger is provided with a first fin and a second fin which are oppositely arranged; the air blower is arranged in a ventilating pipeline; the first copper pipe is wound on the first fin; the second copper pipe is wound on the second fin; the third copper pipe is connected with the inlet ends of the first copper pipe and the second copper pipe; the first check valve is arranged at the inlet end of the first copper pipe; the second check valve is arranged at the inlet end of the second copper pipe; the third check valve is arranged at the inlet end of the third copper pipe; and the control part is used for controlling the transformation of refrigeration and heating of the first fin, controlling starting or closing of the semiconductor hot and cold exchanger and the air blower, and controlling respective opening or closing of the first check valve, the second check valve and the third check valve. According to the car air conditioning system, an air conditioning system of integrating the refrigeration and heating and defrosting is realized, and a car indoor heat island phenomenon in summer is solved.

Description

technical field [0001] The invention relates to an automobile air conditioning system. Background technique [0002] At present, the most widely used automobile air-conditioning system mainly adopts the vapor compression cycle system, and the refrigerant used in cooling will greatly pollute the environment and destroy the ozone layer. As people's awareness of environmental protection becomes stronger and stronger, people are making unremitting efforts to find more environmentally friendly refrigeration methods. [0003] Patent CN102350933A provides a water-cooled thermoelectric refrigeration air conditioner that can only realize the cooling function, but cannot realize the heating function. Patent CN2554030Y provides a thermoelectric vehicle air-conditioning device, which can only realize the cooling function and cannot realize the heating function. And the air conditioner that can only refrigerating function is difficult to be accepted by people like this, so it is diffic...

Problems solved by technology

[0003] Patent CN102350933A provides a water-cooled thermoelectric refrigeration air conditioner that can only realize the cooling function, but cannot realize the heating function

Patent CN2554030Y provides a thermoelectric vehicle air-conditioning device that can only realize the cooling function and cannot realize the heating function

And such an air conditioner with only cooling function is difficult to be accepted by people, so it is difficult to popularize and apply

[0004] In this case, how to make the environmentally friendly thermoelectric refrigeration air conditioner have both heating and cooling functions has become a thorny problem
