。[Claims for Utility Model Registration] (1) A compressor, a condenser, an expansion valve, and a water/refrigerant heat exchanger constitute a refrigerant circuit in which a refrigerant circulates, and between the water/refrigerant heat exchanger and a cooling load. In the chiller device, the cooling water is circulated between the outlet part of the water/refrigerant heat exchanger and the suction part of the compressor, depending on the temperature of the cooling water supplied to the cooling load. A chiller device, characterized in that a refrigerant flow rate adjustment valve for adjusting the flow rate of refrigerant is connected thereto, and a bypass passage is provided in parallel with the refrigerant flow rate adjustment valve. (2) A low-pressure pressure regulating valve is connected between the discharge section of the compressor and the outlet section of the refrigerant flow regulating valve to return the refrigerant discharged from the compressor to the suction section in response to a decrease in the suction pressure of the compressor. The chiller device according to claim 1.
