摘要： A thermal management system includes a five-way valve configured to switch a first circuit mode in which a chiller and a battery are thermally connected and a second circuit mode in which the chiller and an LT radiator are thermally connected, and an ECU configured to control a compressor based on a chiller temperature and a radiator temperature. The ECU is configured to, in a case where switching between the first circuit mode and the second circuit mode is performed by controlling the five-way valve during a heating operation of a refrigeration cycle, control the compressor to reduce a temperature difference between the chiller temperature and the radiator temperature prior to the switching.

摘要： In order to shift a rotation angle of a rotor to a region of a normal mode (for example, a region c) from a region of a heater cut mode (for example, a region e), the rotation angle needs to pass through a region where a flow rate of a refrigerant which is caused to flow through all branch channels becomes zero (a region d). When the refrigerant has a high temperature, there is a possibility of the refrigerant being not cooled, and boiling. Therefore, when a request to switch a normal mode and a heater cut mode is issued, permission/non-permission of switch of the mode is determined by comparison of a temperature of the refrigerant detected by the temperature sensor 26 and an upper limit temperature of the refrigerant.
摘要翻译：为了将转子的旋转角度从加热器切割模式（例如，区域e）的区域移动到正常模式（例如，区域c）的区域，旋转角度需要通过使流过所有分支通道的制冷剂的流量变为零（区域d）的区域。当制冷剂具有高温时，可能制冷剂不被冷却并沸腾。因此，当发出切换正常模式和加热器切断模式的请求时，通过将由温度传感器26检测出的制冷剂的温度与温度传感器26的上限温度进行比较来确定模式切换的许可/不允许制冷剂。

摘要： A switching device of a thermal management system is configured to switch a thermal management circuit to a first circuit mode or a second circuit mode based on the relationship between a battery temperature and a threshold temperature. When a predetermined condition that the amount of change in chiller temperature associated with switching of the circuit mode of the thermal management circuit is expected to be larger than a reference amount is satisfied before the switching of the circuit mode, the control device adjusts the threshold temperature so that the amount of change in chiller temperature becomes smaller than the reference amount.

摘要： A system includes a refrigeration circuit, low-temperature circuit and controller. The refrigeration circuit includes: a tiller for absorbing heat from a colling water to a refrigerant; and a condenser for releasing heat from the refrigerant to an outside, and realizes a refrigeration cycle by circulating the refrigerant therethrough. The low-temperature circuit includes the tiller and an external heat exchanger for absorbing heat from an outside to the first heat medium, and circulate the cooling water therethrough. The controller can change a heat absorption amount of the refrigerant at the tiller. The controller controls the device so that a change in the heat absorption amount of the refrigerant at the first heat exchanger in accordance with a change in a temperature of the first heat medium is reduced, if the temperature of the cooling water flowing through the first heat exchanger changes by a reference value or more.
