PREPARATION OF REFRIGERANT MATERIALS

摘要

Portable refrigeration devices (1) including methods for preparing sorbents (24) for use in such devices, and the sorbents (24) prepared in this way. The methods relate to the substantially complete degassing for the maximization of receiving refrigerant vapor from the evaporator chamber (10) of such refrigeration devices (1), and the maximization of heat transfer to heat sink materials (40) in such refrigeration devices (1).
