PROBLEM TO BE SOLVED: To provide a vehicle cooling/heating system which can cope with cooling request or heating request by usefully utilizing waste-heat of an engine.SOLUTION: A vehicle cooling/heating system 100 comprises: an absorption type heat pump device 20 which generates cold heat (creates cooling water 45) by using absorbent (LiBr solution) and using waste-heat of exhaust gas from a vehicle 90 as a heat source; a compression type refrigerator 10 which performs air cooling of a vehicle 90 by using coolant (R134a); a heater core 54 which is arranged capable of connecting with a circulation path 57 where engine cooling water 55 cooling an engine 91 is flown through so as to heat the vehicle 90; and a cooling water heat recovery device 58 which is arranged to bridge over the path 57a in the circulation path 57 and the path 28a of the absorption type heat pump device 20 so as to perform heat delivery between the path 57a and the path 28a. During heating, heat from the absorbent of the absorption type heat pump device 20 recovered from the waste-heat of the vehicle 90 is given through a cooling water heat recovery device 58 to the engine cooling water 55 so that heat is given to the heat core 54.SELECTED DRAWING: Figure 1
【課題】エンジンの排熱を有効に利用して冷房要求にも暖房要求にも対応することが可能な車両用冷暖房システムを提供する。【解決手段】この車両用冷暖房システム100は、吸収液(LiBr水溶液)を用いるとともに車両90の排気ガスの排熱を熱源に利用して冷熱を発生させる(冷却水45をつくる)吸収式ヒートポンプ装置20と、冷媒(R134a)を用いて車両90の冷房を行う圧縮式冷凍機10と、エンジン91を冷却するエンジン冷却水55が流れる循環経路57に接続可能に配置され、車両90を暖房するためのヒータコア54と、循環経路57における経路57aと、吸収式ヒートポンプ装置20の経路28aとに跨るように配置され、経路57aと経路28aとの間で熱の受け渡しを行う冷却水熱回収器58とを備える。そして、暖房時には、車両90の排熱から回収した吸収式ヒートポンプ装置20の吸収液の熱を冷却水熱回収器58を介してエンジン冷却水55に付与することにより、ヒータコア54に熱を付与する。【選択図】図1
