Dual air conditioner for vehicle

Abstract

The present invention relates to a dual air conditioner for a vehicle, which includes a rear high-temperature pipe that is connected to a rear expansion valve of a rear air conditioner and installed in such a way as to be directly branched from a dual pipe type internal heat exchanger of a front air conditioner, thereby reducing the number of required components and simplifying the manufacturing process with no need to use a connector for branching the rear high-temperature pipe from the front air conditioner, and enhancing a refrigerant movement and reducing material expenses and working process by simplifying piping work and a piping route.

Description

technical field [0001] The present invention relates to a dual air conditioner for a vehicle, and more particularly, to a dual air conditioner for a vehicle including a rear high temperature pipe connected to a rear expander of the rear air conditioner valve and installed directly from the enlarged pipe section of the double-pipe internal heat exchanger of the front air conditioner. Background technique [0002] In general, an air conditioner for a vehicle is an automobile part that is used to cool or heat the interior of the vehicle in summer or winter, or to defrost the windshield in the rainy season or winter to ensure the front and rear vision of the driver. installed in the vehicle. Such an air conditioner typically includes both heating means and cooling means so that it can heat, cool or ventilate the interior of the vehicle by selectively introducing inside air or outside air into the air conditioner, heating or Cools incoming air, and blows heated or cooled air in...

AI Technical Summary

Problems solved by technology

[0022] However, the dual air conditioner for vehicles according to the prior art has a problem in that because the rear high temperature pipe 23 is connected to the front high temperature pipe 16c via the connector 30 so as to divert the refrigerant circulating in the front air conditioner 10, and the diverted Refrigerant circulates to the rear air conditioner 20, so the number of parts and the number of manufacturing processes increase

[0023] In addition, in the case where the distance between the double-pipe internal heat exchanger 15 and the front expansion valve 13 is short, the piping work and piping routing of the front high-temperature pipe 16c and the rear high-temperature pipe 23 become complicated, so the flow of refrigerant flow is unstable

[0024] In addition, since the rear high-temperature pipe 23 is branched from the connector 30 in the vertical direction, the flow of the refrigerant is unstable.
