  • Refrigeration, heating and air conditioning system for vehicles
    Patent number: 5383341
    Abstract: An absorption system for heating, refrigerating and conditioning air for use in vehicles is disclosed. The refrigerant-absorbent mixture, presenting a coefficient of performance of around 0.9, is heated by the waste heat of exhaust gases from the vehicle which has a fuel-driven internal combustion engine. The absorption system is based on the principle of evaporation at relatively low pressure and temperature followed by absorption of refrigerant vapor by the absorbent and then evaporation of the refrigerant from the absorbent when heated by an external heat source.
