1. A sorption system, comprising:
an evaporator structured to contain a working fluid, and operable to evaporate the working fluid to produce a working fluid gas in the evaporator;
a sorber structured to contain a sorption material to sorb the working fluid gas during a sorption phase;
a flow channel extending between the evaporator and the sorber to provide a gas pathway connecting the evaporator and the sorber;
a vapor control valve positioned to control the rate of vapor flow between the evaporator and the sorber through a flow channel, and being selectively operable to permit the flow of working fluid gas through the flow channel, to next stop the flow of working fluid gas through the flow channel, and after stopping the flow to then permit resumption of the flow of working fluid gas through the flow channel; and
a plunger operable to control the rate of vapor flow between the evaporator and the sorber through the flow channel; and
a vacuum barrier material positioned about the sorber, evaporator, and flow channel to provide a reduced pressure therewithin to promote evaporation of the working fluid at a reduced temperature compared to the temperature required at ambient pressure, the vacuum barrier material being a flexible material; and
a temperature controller to adjust the position of the plunger to control the rate of vapor flow through the vapor control valve.
