Patent ID: 8601825

Claim:
An integrated absorption refrigeration and dehumidification system comprising: a compressor including a first stage and a second stage; an absorber containing an absorption solution that is a mixture of a refrigerant and a secondary solution; an after-cooler including a first flow path to receive the absorption solution from the absorber and a second flow path to receive the first warm fluid, the first and second flow paths being thermally coupled such that the first warm fluid heats the absorption solution to separate a first portion of refrigerant from the absorption solution; an auxiliary heat exchanger separate from the after-cooler and including a third flow path to receive the absorption solution from the after-cooler and a fourth flow path to receive the second warm fluid, the third and fourth flow paths being thermally coupled such that the second warm fluid heats the absorption solution to separate a second portion of refrigerant from the absorption solution; a condenser positioned to receive the first portion of refrigerant and the second portion of refrigerant from the auxiliary heater and cool the refrigerant; an expansion valve positioned to receive the refrigerant from the condenser; an evaporator positioned to receive a cool refrigerant from the expansion valve and the first warm fluid from the after-cooler, the evaporator configured to cool the first warm fluid with the cool refrigerant to discharge a cool fluid; and a separator positioned to remove condensate from at least one of the first warm fluid from the after-cooler and the cool fluid from the evaporator, wherein the first warm fluid and the second warm fluid are compressed air from the compressor, and wherein compressed air from the first stage is the second warm fluid having a first stage pressure and compressed air from the second stage is the first warm fluid having a second stage pressure that is greater than the first stage pressure, the second warm fluid flowing to the second stage and being discharged from the second stage as the first warm fluid.
