To prevent a shortage in a refrigerant flow rate to a cooling section for cooling a cooling object from .SOLUTION: A refrigerant cycle system comprises: a refrigerant bifurcation section 13e which bifurcates a flow of refrigerant discharged from an outdoor heat exchanger 16; an indoor evaporator 18 which cools air, before the same is heated at a heating section, through evaporation of one of the flows of refrigerant bifurcated by the refrigerant bifurcation section; cooling sections 19 and 50 which cool a cooling object 80 through the evaporation of the other of the flows of the refrigerant bifurcated by the refrigerant bifurcation section; a refrigerant confluence section 13f which joins the flow of the refrigerant discharged from the indoor evaporator and the flow of the refrigerant discharged from the cooling sections and sends the joined flow of the refrigerant to an intake of a compressor; and a control section 60 which controls refrigerant discharge capacity of the compressor on the basis of a physical amount related to a target cooling amount of the indoor evaporator when a target cooling amount of the cooling object is less than the target cooling amount of the indoor evaporator or on the basis of the physical amount related to the target cooling amount of the cooling object when the target cooling amount of the cooling object is larger than that of the indoor evaporator.SELECTED DRAWING: Figure 15
【課題】冷却対象物を冷却する冷却部側への冷媒流量が不足することを抑制する。【解決手段】室外熱交換器16から流出した冷媒の流れを分岐する冷媒分岐部13eと、冷媒分岐部にて分岐された一方の冷媒を蒸発させて、加熱部にて加熱される前の空気を冷却する室内蒸発器18と、冷媒分岐部にて分岐された他方の冷媒を蒸発させて冷却対象物80を冷却する冷却部19、50と、室内蒸発器から流出した冷媒の流れと冷却部から流出した冷媒の流れとを合流させて、圧縮機の吸入口側へ流出させる冷媒合流部13fと、冷却対象物の目標冷却量が室内蒸発器での目標冷却量よりも小さい場合、室内蒸発器での目標冷却量に関連する物理量に基づいて圧縮機の冷媒吐出能力を制御し、冷却対象物の目標冷却量が室内蒸発器での目標冷却量よりも大きい場合、冷却対象物の目標冷却量に関連する物理量に基づいて圧縮機の冷媒吐出能力を制御する制御部60とを備える。【選択図】図15
