Abstract
A sorption cooling device capable of providing cooling over an extended period of time. The sorption cooling device is particularly useful in a temperature-controlled shipping container that is required to maintain a temperature below ambient for an extended period of time. In one embodiment, the cooling device includes a means for restricting the flow of refrigerant liquid to control the degree of cooling over an extended period of time.
