Air-conditioning system for vehicle

Abstract

A vehicle air-conditioning system includes three separate chambers formed by partitions. An interior heat exchanger is disposed in the first chamber for heat exchange with air introduced into the first chamber, and first chamber has an inside-air introduction port for admitting air from the vehicle passenger compartment into the first chamber and an air discharge port for discharging air into the compartment. An exterior heat exchanger is disposed in the second chamber for heat exchange with air introduced into the second chamber, and second chamber has an open-air introduction port for admitting air from outside of the vehicle into the second chamber and an air discharge port for discharging the air to outside of the vehicle. A compressor is mounted in communication with one of two refrigerant pipes for compressing a refrigerant, the two refrigerant pipes being adapted to circulate the refrigerant between the interior and exterior heat exchangers, and a depressurizing means is mounted in the other refrigerant pipe for depressurizing the refrigerant flowing between the interior and exterior heat exchangers. The compressor is disposed in the third chamber which is partitioned from the first and second chambers and the vehicle passenger compartment.
