Patent ID: 7143589

Claim:
A closed-loop sorption cooling system for providing cooled air to the cabin of a vehicle, the sorption cooling system comprising: an evaporator; a condenser adapted for fluid communication with said evaporator; and a plurality of adsorbent beds adapted for fluid communication with said condenser and said evaporator, each adsorbent bed comprising: i. a fluid impermeable casing comprising a refrigerant inlet, a refrigerant outlet, a coolant inlet and a coolant outlet; ii. a first desiccant sheet comprising a first aperture therethrough and a first adsorbent side; and iii. a second desiccant sheet comprising a second aperture therethrough and a second adsorbent side; iv. a refrigerant flow path for flowing a refrigerant fluid between said refrigerant inlet and refrigerant outlet, said refrigerant path being at least partially defined by said first and second adsorbent sides; and v. a coolant flow path for flowing a coolant fluid between said coolant inlet and said coolant outlet, said coolant flow path being fluidly isolated from said refrigerant flow path and being adjacent to at least one of said first and second desiccant sheets; wherein said first and second apertures are a portion of one of said refrigerant flow path and said coolant flow path.
