VEHICLE Russian patent published in 1995 - IPC

FIELD: vehicle saloon heating and conditioning equipment. SUBSTANCE: vehicle has engine 2 with cooling system having pump 3 and radiator 4, which are interconnected through pipelines 5,6,7. Saloon heating system has radiator 11 connected with cooling system via pipelines 8 and 9 through cock unit. Radiator 11 and fan 12 are disposed adjacent to air duct (branch pipe) 14. Conditioning of saloon is provided by specific arrangement of radiators. Additional radiator 17 positioned proximate to radiator 4 is connected with pump 22 and cock unit 10 via pipelines 18, 19 to form additional main. Radiator 11 is provided with thermoelectric bar battery with one junctions interacting with heat-exchanging surface of radiator 11 and other junctions contacting with cooling air. In cold time hot heat carrier is transferred from engine 2 via pipeline 9 through cock unit 10 to radiator 11, where it transmits heat to air supplied by fan 12. Air is conducted through air duct 14 into vehicle saloon. Heat carrier is returned into cooling system. In hot time cock unit 10 is changed over for main formed by pipelines 18,19. Pump 22 pumps heat carrier through cock unit 10 and radiator 11 withdraws heat by Peltier effect from air supplied into saloon and transmits it to heat carrier, which is cooled by air in radiator 17. EFFECT: increased efficiency and enhanced reliability in operation. 7 cl, 6 dwg
