ABSTRACT:
Sorption cooling system of the present invention comprises a transportable cooling unit and a stationary charging (i.e. desorption) station. The transportable cooling unit includes an adsorption container containing an adsorption medium, a cooling container containing a liquid operating medium, and a heat exchanger contained within the cooling container and being surrounded by the liquid operating medium. An operating medium vapor conduit connects the adsorption container and the cooling container, and includes a shut off device which renders the operating medium vapor conduit selectively closable. The stationary charging station is detachable from the cooling unit, and includes a temperature controlled heating box having an opening for receiving the adsorption medium container of the transportable cooling unit, so that a discharged adsorption medium container can be selectively heated to desorb the operating fluid therefrom to form vapor which is condensed to liquid form and stored in the cooling container. After desorbing the operating medium from the adsorption medium using the charging station, the shut off device is closed and the cooling unit is removed from the charging station and allowed to cool, thereby charging the cooling unit for a new use.
