Benefits of technology

[0012]Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide an air-conditioning system for vehicles, in which expansion means and an internal heat exchanger are formed integrally with each other or expansion means, an internal heat exchanger and an accumulator are formed integrally with one another in an air-conditioning system using carbon dioxide (CO2) as refrigerant so as to minimize and simplify a refrigerant line, thereby reducing the cost and a loss of energy according to a reduction in the number of assembly processes thereof.

Problems solved by technology

In general, it has been widely known that CFC refrigerant called Freon gas destructs the ozone layer, and the CFC refrigerant rises as an environmental problem all over the world.
However, the conventional air-conditioning system for vehicles has a problem in that its manufacturing cost rises and a loss of energy is increased due to an extended and complicated refrigerant line since the expansion valve 2, the internal heat exchanger 6 and the accumulator 4 are separately connectively mounted on the refrigerant line.

Abstract

The present invention relates to an air-conditioning system for vehicles, in which expansion means and an internal heat exchanger are formed integrally with each other or expansion means, an internal heat exchanger and an accumulator are formed integrally with one another in an air-conditioning system using carbon dioxide (CO2) as refrigerant so as to minimize and simplify a refrigerant line, thereby reducing the cost and a loss of energy according to a reduction in the number of assembly processes thereof. The air-conditioning system includes a compressor, a gas cooler, expansion means and an evaporator as a refrigerant line for circulating refrigerant in this order.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an air-conditioning system for vehicles, and more particularly, to an air-conditioning system for vehicles, in which expansion means and an internal heat exchanger are formed integrally with each other or expansion means, an internal heat exchanger and an accumulator are formed integrally with one another in an air-conditioning system using carbon dioxide (CO2) as refrigerant so as to minimize and simplify a refrigerant line, thereby reducing the cost and a loss of energy according to a reduction in the number of assembly processes thereof.[0003]2. Background Art[0004]In general, it has been widely known that CFC refrigerant called Freon gas destructs the ozone layer, and the CFC refrigerant rises as an environmental problem all over the world. Thus, in advanced countries, new alternative refrigerants, which can minimize the environmental problem, have been developed and applied to home ...
