VEHICLE AIR-CONDITIONING DEVICE

摘要

A vehicle air-conditioning device is provided that makes it possible to avoid the occurrence of condensation at a heat exchanger, and to avoid decreases in the heat exchange efficiency of the heat exchanger caused by uneven temperature distribution in the heat exchanger itself. This vehicle air-conditioning device employs a configuration comprising: a heat exchanger that performs heat exchange between air passing through a first flow path and air flowing through a second flow path; and a switching means that alternately switches either the first flow path or the second flow path from a discharge path that discharges the air inside the vehicle toward the outside of the vehicle to an intake path that guides air from outside of the vehicle into the vehicle, and switches the other flow path from the intake path to the discharge path.

1. A vehicle air-conditioning apparatus comprising:
a first heat exchanger that performs heat exchange between air passing through a first flow path and air passing through a second flow path; and a switching section that alternatively switches one of the first flow path and the second flow path from an exhaust flow path to an intake flow path and the other one of the first flow path and the second flow path from the intake flow path to the exhaust flow path, internal air from a vehicle interior being discharged to the outside of the vehicle interior through the exhaust flow path and external air from the outside of the vehicle interior being introduced into the vehicle interior through the intake flow path.
