Document Type and Number:
Japanese Patent JP2015037894
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle air conditioner which achieves compactification of an air-conditioning system utilizing a refrigerant circuit and a coolant circuit and reduces heat loss thereby improving the performance.SOLUTION: A vehicle air conditioner includes: an outdoor heat exchanger 10 which conducts heat exchange between a refrigerant of a heat pump and air at the exterior of a vehicle cabin; a water refrigerant heat exchanger 30 which flows the refrigerant and a coolant thereinto to move heat from the refrigerant to the coolant; a heat radiation part 50 which flows the coolant thereinto to radiate the heat from the coolant to air; circulation means 52 which circulates the coolant between the water refrigerant heat exchanger 30 and the heat radiation part 50; and a draft air duct 200 which blows air into the vehicle cabin and in which the heat radiation part 50 is disposed in the middle thereof. The outdoor heat exchanger 10 is integrally joined to the water refrigerant heat exchanger 30.
