<p>In the present invention, a vehicle heat management system is provided with: a heat medium-heating heat exchanger (15) for exchanging heat between a heat medium discharged by a second pump (12) and a high pressure-side refrigerant of a refrigeration cycle (31), and heating the heat medium; a heat medium-cooling heat exchanger (14) for exchanging heat between a heat medium discharged by a first pump (11) and a low-pressure refrigerant of the refrigeration cycle (31), and cooling the heat medium; temperature regulated machines (18, 19, 20), the temperatures of which are regulated by the heat medium; a first changeover valve (21) and second changeover valve (22) for changing over, with respect to the machines subject to temperature regulation, between a cooling state in which the heat medium is circulated with the heat medium-cooling heat exchanger (14) and a heating state in which the heat medium is circulated with the heat medium-heating heat exchanger (15); and a compressor controlling means (70d) for increasing the refrigerant discharge capability of a compressor (32) of the refrigeration cycle (31) either while the first changeover valve (21) and second changeover valve (22) are in the midst of changing over between the cooling state and the heating state, or before said changeover is made.</p> |
