<p>The present invention relates to a method of filling a canister with propellant gas by performing the steps of providing a canister having a specific volume filled with activated carbon, the activated carbon having a first temperature and providing a volume of liquefied propellant gas at a second temperature and a first elevated pressure preventing the liquefied propellant gas from evaporating. The invention further relates to the step of evacuating the canister for creating a state of vacuum within the canister, thereby cooling the activated carbon to a third temperature, preferably lower than the second temperature, the step of injecting the volume of liquefied propellant gas into the canister at a second elevated pressure preventing the liquefied propellant gas from evaporating, and the step of allowing the liquefied propellant gas to evaporate and in doing so consuming energy as evaporation heat, the energy being generated due to the propellant gas being adsorbed by the activated carbon, thereby reducing the heating of the activated carbon.</p> |
