HEAT MANAGEMENT SYSTEM FOR VEHICLE

To provide a heat management system for a vehicle capable of heating a heating object or cooling a cooling object, and capable of enhancing heating capacity and cooling capacity.SOLUTION: A heat management system for a vehicle includes: a refrigerant circuit 1 which has a first compressor 10A and a second compressor 10B, a condenser for performing heat radiation to a heating medium or to the outside air by a refrigerant R, a first evaporator 4 for performing heat absorption from the inside air by the refrigerant R which is expanded by a first expansion valve 11 via the condenser 5, and a second evaporator 6 for performing heat absorption from a cooling medium or the outside air by the refrigerant R which is expanded by a second expansion valve 12 via the condenser 5; and at least one medium circuit out of a heating medium circuit 2 having a radiator 61 for performing heat radiation to a heating object by a heating medium pump 16 or a heating medium H, and a cooling medium circuit 3 having a heat absorber 62 for performing heat absorption from a cooling object by a cooling medium pump 36 and a cooling medium L. At least one of heat radiation to the heating medium in the condenser 5 and heat absorption from the cooling medium in the second evaporator 4 is performed.SELECTED DRAWING: Figure 1 【課題】加熱対象の加熱、あるいは冷却対象の冷却をすることができ、しかもその加熱能力や冷却能力を高めることができる車両用熱マネジメントシステムを提供する。【解決手段】第１圧縮機１０Ａ及び第２圧縮機１０Ｂ、冷媒Ｒで加熱用媒体又は外気に放熱を行う凝縮器と、凝縮器５を経由し第１膨張弁１１で膨張された冷媒Ｒで内気から吸熱を行う第１蒸発器４及び凝縮器５を経由し第２膨張弁１２で膨張された冷媒Ｒで冷却用媒体又は外気から吸熱を行う第２蒸発器６を有する冷媒回路１と、加熱用媒体ポンプ１６及び加熱用媒体Ｈで加熱対象に放熱を行う放熱器６１を有する加熱用媒体回路２と、冷却用媒体ポンプ３６及び冷却用媒体Ｌで冷却対象から吸熱を行う吸熱器６２を有する冷却用媒体回路３との少なくとも一方の媒体回路とを備える。凝縮器５における加熱用媒体への放熱及び第２蒸発器４における冷却用媒体からの吸熱の少なくとも一方を行う。【選択図】図１
