THERMAL MANAGEMENT SYSTEM FOR VEHICLE
First Claim
1. A thermal management system for a vehicle, comprising:
- a first pump that draws and discharges a heat medium;
a compressor that draws and discharges a refrigerant in a refrigeration cycle;
a high-pressure side heat exchanger that exchanges heat between a high-pressure side refrigerant in the refrigeration cycle and the heat medium circulated by the first pump;
a heat medium-outside air heat exchanger that exchanges heat between the heat medium circulated by the first pump and outside air; and
a pump control unit that controls an operation of the first pump such that the operation of the first pump is continued even after the compressor is stopped whereinin a case where the operation of the first pump is continued after the compressor is stopped, the pump control unit stops the first pump when a difference obtained by subtracting a temperature of the outside air from a temperature of the heat medium is determined to be equal to or less than a first predetermined value.

Abstract
A thermal management system for a vehicle includes a high-temperature side pump that draws and discharges a heat medium, a compressor that draws and discharges a refrigerant in a refrigeration cycle, a high-pressure side heat exchanger that exchanges heat between a high-pressure side refrigerant in the refrigeration cycle and the heat medium circulated by the high-temperature side pump, a heat medium-outside air heat exchanger that exchanges heat between the heat medium circulated by the high-temperature side pump and outside air, and a pump control unit that controls an operation of the high-temperature side pump such that the operation of the high-temperature side pump is continued even after the compressor is stopped. Thus, the cycle efficiency exhibited when restarting the compressor can be improved.
