The present invention relates to a heat management device for a vehicle, which, when switching from a first mode in which there is a heating request from an air conditioner and there is a cooling request from a battery to a second mode in which there is a heating request from the air conditioner and there is no cooling request from the battery, reduces the degree of opening of an electric expansion valve of a refrigerant circuit for a predetermined period of time. After the predetermined period has elapsed, the first mode is switched to the second mode.
本发明涉及一种车辆的热管理装置,在从存在空调装置的制热要求且存在蓄电池的制冷要求的第一模式向存在空调装置的制热要求且不存在蓄电池的制冷要求的第二模式切换时,在规定期间内,减小制冷剂回路的电气式膨胀阀的开度。并且,在规定期间经过后,从第一模式向第二模式切换。
