Provided is a heat source unit capable of demonstrating sufficient capability by stable regulation of the valve opening of motor-operated valves provided in corresponding fashion to each of a plurality of heat exchangers mutually connected in parallel. A first heat exchanger (24) and a second heat exchanger (25) are mutually connected in parallel, and a first heat-source-side flow-rate-regulating valve (26) and a second heat-source-side flow-rate-regulating valve (27) for regulating flow rate are provided on an upstream side when each function as an evaporator. A heat-source-side controller (20) specifies a total valve opening of the first heat-source-side flow-rate-regulating valve (26) and the second heat-source-side flow-rate-regulating valve (27) on the basis of the discharge refrigerant temperature of the compressor (21), and a relationship between the valve opening of the first heat-source-side flow-rate-regulating valve (26) and the valve opening of the second heat-source-side flow-rate-regulating valve (27) is regulated on the basis of the temperature of refrigerant flowing from the first heat-source-side flow-rate-regulating valve (26) toward the first heat exchanger (24), and the temperature of refrigerant flowing from the second heat-source-side flow-rate-regulating valve (27) toward the second heat exchanger (25). |
