Abstract: A chilling machine includes a refrigerant circuit through which refrigerant circulates; a compressor, a condenser, a first expander, an evaporator and an accumulator that are provided on the refrigerant circuit; a coolant circuit including a first supply path and a second supply path to which coolant is supplied at different temperatures; and a chiller that cools the coolant. The coolant circuit includes a first supply path through which low temperature coolant is supplied to the first supply destination, and a second supply path through which high temperature coolant is supplied to the second supply destination. The refrigerant circuit includes a first reheater that increases temperature of the coolant supplied through the second supply path by heats of the refrigerant discharged from the compressor, a first selective path that supplies the refrigerant discharged from the compressor to the condenser by bypassing the first reheater, a second selective path that supplies the refrigerant discharged from the compressor to the condenser through the first reheater, and a controller that adjusts quantity of the refrigerant passing through the first selective path and quantity of the refrigerant passing through the second selective path.
