1. An in-vehicle temperature control system mounted on a vehicle, comprising: a low-temperature circuit having a first heat exchanger and in which a first heat medium circulates through the first heat exchanger; a heat dissipation unit for dissipating heat to an air flowing into an interior of the vehicle; a refrigeration circuit in which a refrigerant circulates and for absorbing heat from the first heat medium to the refrigerant at the first heat exchanger and dissipating heat from the refrigerant at the heat dissipation unit; a ratio adjusting device for adjusting a heat dissipation unit passing ratio which is a ratio of a flow rate of air passing through the heat dissipation unit among air flowing into the interior of the vehicle; and a controller configure to control an apparatus capable of adjusting a heat transfer amount which is absorbed to the refrigerant at the first heat exchanger in the refrigeration circuit and is dissipated from the refrigerant at the heat dissipation unit, and the ratio adjusting device, wherein, when the temperature of the first heat medium flowing through the first heat exchanger decreases by a reference value or more, the controller is configured to control the apparatus so that the heat transfer amount is increased and controls the ratio adjusting device so that the heat dissipation unit passing ratio is decreased, before the temperature of the first heat medium flowing through the first heat exchanger decreases by the reference value or more.
