Abstract
A thermal storage device for maintaining the temperature of an article at a desired temperature for a length of time comprises a compartment within which the article may be positioned, an evaporator which is disposed in heat exchange relation with respect to the compartment, a receiver which is fluidly connected to the evaporator, a sorber which is fluidly connected between the evaporator and the receiver and which includes a sorbent that is capable of adsorbing a refrigerant, a desorbing device for desorbing the refrigerant from the sorbent, and a power connection device for releasably connecting an external power supply to the desorbing device. When the desorbing device is connected to the external power supply, the refrigerant is desorbed from the sorbent and communicated to the receiver. In addition, after the desorbing device is disconnected from the external power supply, the refrigerant within the receiver is evaporated in the evaporator and adsorbed onto the sorbent to thereby produce a cooling effect in the compartment.
