VEHICLE HEAT MANAGEMENT SYSTEM

Title:

VEHICLE HEAT MANAGEMENT SYSTEM

Document Type and Number:

WIPO Patent Application WO/2015/133083

Kind Code:

A1

Abstract:

This vehicle heat management system is provided with: a high-temperature-side pump (12) that draws in and discharges a heat medium; a compressor (23) that draws in and discharges the refrigerant of a refrigeration cycle (22); a high-pressure-side heat exchanger (15) that exchanges heat between the high-pressure-side refrigerant of the refrigeration cycle (22) and the heat medium circulated by the high-temperature-side pump (12); a heat-medium/ouside-air heat exchanger (13) that exchanges heat between outside air and the heat medium circulated by the high-temperature-side pump (12); and a pump control unit (50a) that controls the operation of the high-temperature-side pump (12) so that the operation of the high-temperature-side pump (12) continues even if the compressor (23) is stopped. Thus, the cycling efficiency when restarting the compressor can be increased.
