HEAT MANAGEMENT SYSTEM

WIPO Patent Application WO/2023/120022

A1

The present invention minimizes the thermal capacity of a heat medium which circulates through a heat medium circuit, so as to improve the responsiveness to a temperature change of the heat medium, and to improve the comfort during air conditioning operation/utilization while performing appropriate temperature regulation of on-board equipment.　A heat management system comprises: a heat pump unit (10) in which a first heat medium circulates; and a heat medium circuit (20, 30, 40) in which a second heat medium circulates, the second heat medium having been subjected to heat exchange with the first heat medium in a heat exchanger provided to the heat pump unit. The heat medium circuit comprises: an interior heat exchanger (4, 9) which carries out heat exchange between the second heat medium and air supplied to a vehicle interior; a battery heat exchanger (42) which carries out heat exchange between the second heat medium and an on-vehicle battery; a series flow passage to which the interior heat exchanger and the battery heat exchanger are connected in series, and through which the second heat medium that has passed through a heat exchanger circulates; a bypass flow passage through which the second heat medium that has passed through a heat exchanger for heat absorption bypasses the battery heat exchanger and circulates to the interior heat exchanger; and a switching means that switches between the series flow passage and the bypass flow passage.
