Vehicle air conditioning device

Abstract

A vehicle air conditioning device (1) is provided with a first heat medium circuit (10), a second heat medium circuit (20), a heat medium heat exchanger (13), and a control unit (60). The first heat medium circuit circulates a first heat medium via a first heat source (11, 11a) that generates heat as the vehicle travels. The second heat medium circuit circulates the second heat medium through second heat sources (21, 30, 42) capable of adjusting the amount of heat generated and a heater core (23) for heating the blown air supplied to the space to be air-conditioned by heat exchange. The heat medium heat exchanger exchanges heat between the first heat medium circulating in the first heat medium circuit and the second heat medium circulating in the second heat medium circuit. The control unit controls the operation of the first heat medium circuit and the second heat medium circuit.
