Title: REFRIGERATION CYCLE DEVICE
Abstract:
A refrigeration cycle device is connected to a load-side via a water return-side header pipe and a water supply-side header pipe connected by bypass piping provided with a bypass valve, wherein the refrigeration cycle device has: a compressor that compresses refrigerant and discharges same to refrigerant piping; an air heat exchanger by which heat is exchanged between the air and the refrigerant flowing in the refrigerant piping; an expansion valve that regulates the pressure of the refrigerant flowing in the refrigerant piping; a water heat exchanger that feeds water supplied from the water return-side header pipe to the water supply-side header pipe after heat is exchanged between the water and the refrigerant; an outlet pressure sensor that is provided on the water outlet side of the water heat exchanger and that measures the water pressure; and a control device. The control device controls the opening of the bypass valve so that the value of the water pressure measured by the outlet pressure sensor is a predetermined target value.
