A vehicular heat management system is provided with: a refrigerant circuit (20); a first heat medium circuit (C1) in which a heat medium for exchanging heat with low-pressure side refrigerant of the refrigerant circuit is circulated; a second heat medium circuit (C2) in which a heat medium for exchanging heat with high-pressure side refrigerant of the refrigerant circuit is circulated; and a switch device (35, 36, 37, 38, 45, 46, 50i, 61, 62) that, on the basis of the temperature of the heat medium of the first heat medium circuit, switches between a link mode in which the first heat medium circuit and the second heat medium circuit are linked, and a non-link mode in which the first heat medium circuit and the second heat medium circuit are not linked. When it is determined that a heat-absorbing heat exchanger (13) for causing the heat medium of the first heat medium circuit to absorb heat is frosted, a heat medium temperature adjustment device (50) increases the temperature of the heat medium of the second heat medium circuit. Thus, the heat medium temperature can be prevented from being decreased more than necessary, whereby the heat for melting the frost attached to the heat-absorbing heat exchanger can be reliably obtained.
