VEHICLE AIR CONDITIONING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a vehicle air conditioning device that can supply air-conditioning air with a stable heat amount irrespective of an operation state of an internal combustion engine.

SOLUTION: The vehicle air conditioning device 1 includes: a steam generator 11 for exchanging heat between a working fluid and the waste heat of the engine 50 to evaporate the working fluid; a first heater core 26 provided at an air flow path 21 and exchanging heat between the air-conditioning air passing therethrough and the working fluid evaporated by the steam generator 11; a second heater core 27 provided at the air flow path 21 and exchanging heat between the air-conditioning air passing therethrough and a coolant of the engine 50; a setting means for setting a ratio of an amount of air-conditioning air to pass through the first heater core 26 to an amount of air-conditioning air to pass through the second heater core 27 based on detection results detected by a water temperature sensor 31 and a crank angle sensor 32; and a switching damper 28 for regulating the air-conditioning air amount ratio based on a setting result set by the setting means.
