Abstract
A gas storage apparatus comprises a pressure vessel in the form of a cylinder, closed by a valve, containing a non-permanent gas having under its storage conditions a gas phase and a liquid phase. A jacket formed of plastics sachets surrounds and is in heat transfer relationship with the outer surface of the cylinder. The sachets define closed compartments containing a heat release substance which is liquid at 20° C. On opening the valve, the non-permanent gas is delivered from the cylinder. The liquid phase of the non-permanent gas absorbs heat from the heat release substance which undergoes fusion. The heat release substance may be water.
Claims18
A gas storage apparatus comprising a pressure vessel containing a non-permanent gas having under its storage conditions a gas phase and liquid phase, a valve closing the pressure vessel, a jacket surrounding and in heat transfer relationship with the outer surface of the pressure vessel, and a heat release substance stored within the jacket, the heat release substance being of a kind that when gas is dispensed from the pressure vessel releases heat to the said liquid phase by undergoing a change of state from liquid to solid, wherein the jacket has a configuration preventing physical contact between the pressure vessel and the heat release substance and the jacket comprises a plurality of closed compartments which enclose the heat release substance and permit thermal currents to be established within the heat release substance when in liquid state.
