A vehicle-mounted temperature adjusting device which can suppress reduction in battery performance. The device (1) includes a first heat circuit (3) and a refrigeration circuit (2). The first heat circuit has a battery heat exchange part (35) exchanging heat with a battery and a first heat exchange part (27), and configured so that a first heat medium circulates therethrough. The refrigeration circuit has a compression part (21) compressing a refrigerant to raise its temperature, a second heat exchange part (22) radiating heat from the refrigerant, an expansion part (25) making the refrigerantexpand, and the first heat exchange part making the refrigerant absorb heat from the first heat medium to make the refrigerant evaporate, and is configured to realize a refrigeration cycle by the refrigerant circulating therethrough. The first heat circuit includes a bypass flow path (3d) bypassing the battery heat exchange part and an adjusting device (33) adjusting a flow rate of the first heatmedium flowing through the bypass flow path. The adjusting device is controlled so that a ratio of a flow rate of the first heat medium flowing through the bypass flow path becomes greater, when thetemperature of the battery is relatively low, compared to when it is relatively high.
一种车载温度调节装置,抑制电池的性能降低。车载温度调节装置(1)具备第1热回路(3)和冷冻回路(2)。第1热回路具有与电池进行热交换的电池热交换部(35)和第1热交换部(27),且构成为供第1热介质循环。冷冻回路具有压缩制冷剂而使其升温的压缩部(21)、使热从制冷剂放出的第2热交换部(22)、使制冷剂膨胀的膨胀部(25)、及使制冷剂从第1热介质吸热而使制冷剂蒸发的第1热交换部,且构成为实现冷冻循环。第1热回路具备绕过电池热交换部的旁通流路(3d)、和调整在旁通流路流通的第1热介质的流量的调整装置(33)。调整装置被控制为,在电池的温度相对较低时,与相对较高时相比,使在旁通流路流通的所述第1热介质的流量比率变多。
