一种应用于混合动力车辆的车辆用空调装置,具备:第一热介质回路(20),该第一热介质回路供由内燃机(EG)的排热加热了的第一热介质循环;以及第二热介质回路(30),该第二热介质回路供由能够对加热能力进行调节的加热部(33)加热了的第二热介质循环。在第一空调模式中,将由配置于第一热介质回路(20)的第一加热用热交换部(21)加热了的送风空气向车室内吹出。在第二空调模式中,将由配置于第二热介质回路(30)的第二加热用热交换部(31)加热了的送风空气向车室内吹出。在第三空调模式中,将由第一加热用热交换部(21)和第二加热用热交换部(31)这双方加热了的送风空气向车室内吹出。
An air conditioner applied to a hybrid vehicle includes a first heat medium circuit, a first heating heat exchanger, a first pump, a first hydraulic pump capacity controller, a second heat medium circuit, a second heating heat exchanger, a second pump, and a second hydraulic pump capacity controller. The first heat medium circuit and the second heat medium circuit are configured to be independent from each other to set a first air conditioning mode, a second air conditioning mode and a third air conditioning mode. When a temperature difference calculated by subtracting a first temperature of the first heat medium from a second temperature of the second heat medium is lower than or equal to a predetermined reference temperature difference during the third air conditioning mode, the first air conditioning mode is set by switching from the third air conditioning mode.
