  • Air cooled absorption cooling system operable by low grade heat
    Patent number: 9134056
    Abstract: An air-cooled absorption refrigerating system and method is provided An evaporated refrigerant is mixed with a weak refrigerant stream Portions of the evaporated refrigerant are absorbed into the weak refrigerant stream via air-cooled absorber means to form a reconstituted solution which is pumped into heater means in heat exchange relationship with a hot weak refrigerant. The hot weak refrigerant stream is conducted therefrom Refrigerant is evaporated from the reconstituted solution via generator means in heat exchange relationship with a heat transfer fluid The generator means stream is separated into a hot weak refrigerant stream and a main refrigerant vapor stream The main refrigerant vapor stream is condensed via air-cooled condenser means The pressure of a condensed refrigerant vapor stream is reduced and conducted into evaporator means, where it is evaporated to form an evaporated refrigerant stream and conducted therefrom.
