  "textContent": "Provided is a vehicle air conditioning device with a simple structure which can quickly raise the temperature of engine cooling water used for heating the air in a vehicle cabin in an engine start period in a low ambient temperature. The vehicle air conditioning device comprises the following elements integrally connected with each other: a first water heat exchanger (26) provided in the middle of a passage through which an engine cooling water flows from the water jacket of an engine (3) to a heater core (8a), a second water heat exchanger (27) provided in the middle of a passage through which the engine cooling water flows from the heater core (8a) to the water jacket of the engine (3), and a first external heat exchanger (18) for refrigerant condensation provided between the first and second water heat exchangers (26, 27). In the engine start period in a low ambient temperature, the engine cooling water flowing from the water jacket to the heater core (8a) is heated by heat released from the first external heat exchanger (18) to rise in temperature.",
