Abstract
A system includes a refrigeration circuit, low-temperature circuit and controller. The refrigeration circuit includes: a tiller for absorbing heat from a colling water to a refrigerant; and a condenser for releasing heat from the refrigerant to an outside, and realizes a refrigeration cycle by circulating the refrigerant therethrough. The low-temperature circuit includes the tiller and an external heat exchanger for absorbing heat from an outside to the first heat medium, and circulate the cooling water therethrough. The controller can change a heat absorption amount of the refrigerant at the tiller. The controller controls the device so that a change in the heat absorption amount of the refrigerant at the first heat exchanger in accordance with a change in a temperature of the first heat medium is reduced, if the temperature of the cooling water flowing through the first heat exchanger changes by a reference value or more.
