Abstract
A system includes: a low-temperature circuit having a chiller and in which a cooling water circulates therethrough; a heat dissipation unit for dissipating heat to an air; a refrigeration circuit in which a refrigerant circulates and for absorbing heat from the cooling water to the refrigerant at the chiller and dissipating heat from the refrigerant at the heat dissipation unit; a ratio adjusting device for adjusting a heat dissipation unit passing ratio; and a controller for controlling an heat transfer amount adjusting apparatus capable of adjusting the heat transfer amount in the refrigeration circuit and the ratio adjusting device. If it is predicted that the temperature of the cooling water decreases, the controller controls the apparatus so that the heat transfer amount is increased and controls the ratio adjusting device so that the ratio is decreased, before the temperature of the cooling water flowing through the chiller decreases.
