Patent number: 12134300Abstract: A heat control device is provided in a vehicle including a first thermal circuit that circulates a coolant and a second thermal circuit that circulates a refrigerant while changing the state of the refrigerant and is able to exchange heat with the first thermal circuit. When there is a heat discharge request from the second thermal circuit, the heat control device includes a determination unit configured to determine an amount of operation of each of a plurality of units which are used to discharge heat such that the heat discharge request is satisfied and the sum of power consumption values of the plurality of units is minimized.Type: GrantFiled: March 23, 2020Date of Patent: November 5, 2024Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Ryuichi Wada, Tatsuya Masuhisa, Nobukazu Kuribayashi, Shinsaku Isomura

Patent number: 11707966Abstract: A device installed in a vehicle including a first thermal circuit, a second thermal circuit, and a third thermal circuit, is configured to arbitrate a heat request of the first thermal circuit, a heat request of the second thermal circuit, and a heat request of the third thermal circuit. The device is configured to acquire a heat absorption amount requested by the first thermal circuit, the second thermal circuit, and the third thermal circuit, and configured to set, as a target value of a transfer heat amount in which heat exchange is performed between the second thermal circuit and the third thermal circuit, a larger one of a heat dissipation amount requested by the second thermal circuit and a heat amount difference in which a heat dissipation amount requested by the third thermal circuit is subtracted from a heat absorption amount requested by the first thermal circuit.Type: GrantFiled: February 10, 2021Date of Patent: July 25, 2023Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATIONInventors: Takayuki Kawabe, Tatsuya Masuhisa, Nobukazu Kuribayashi, Shinsaku Isomura

Patent number: 10106012Abstract: An air-conditioner for a vehicle includes: a first circuit in which a cooling medium circulates; a heater heating the cooling medium; a first pump disposed in the first circuit; a second circuit cooling a heat emitting portion; a second pump disposed in the second circuit; an adjustment portion controlling a circulation amount of the cooling medium flowing in the first circuit and a circulation amount of the cooling medium flowing in the second circuit; and a control portion. The vehicle includes a regenerative device, and a storage device is charged with electric energy recovered by the regenerative device. When the regenerative device is recovering the electric energy and when it is determined that power in the storage device needs to be consumed, the control portion drives the heater to heat the cooling medium such that the power in the storage device is converted into heat energy.Type: GrantFiled: March 26, 2015Date of Patent: October 23, 2018Assignee: DENSO CORPORATIONInventors: Akira Umehara, Shinsaku Isomura, Keita Honda
