Title:
TEMPERATURE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/163712
Kind Code:
A1
Abstract:
This temperature control system (401) has: a first mode wherein a heating operation in which a heat radiation device (22) heats air via a refrigeration cycle circuit (20) is carried out by a first thermal coupler (458) thermally coupling a second cooling water circuit (250) and a third cooling water circuit (350), a second thermal coupler (358) thermally separating the third cooling water circuit (350) and a fourth cooling water circuit (450), a drive system heat exchanger (259) absorbing heat from a drive system component (3), and a refrigerant being caused to absorb heat from cooling water via a first heat exchanger (26), and a storage battery (2) is cooled via a storage battery heat exchanger (53) using cooling water cooled by heat exchange with outside air via a second outdoor heat exchanger (452); and a second mode wherein a heating operation in which the heat radiation device (22) heats air via the refrigeration cycle unit (20) is carried out by the first thermal coupler (458) thermally separating the second cooling water circuit (250) and the third cooling water circuit (350), the second thermal coupler (358) thermally coupling the third cooling water circuit (350) and the fourth cooling water circuit (450), a first bypass switching valve (457) being switched so that the cooling water flows through a first bypass path (456), the cooling water being heated via a heater (54), and the refrigerant being caused to absorb heat from the cooling water via the first heat exchanger (26).
