GAS STORAGE APPARATUS

摘要

A gas storage apparatus comprises a pressure vessel in the form of a cylinder (2), closed by a valve (4), containing a non-permanent gas having under its storage conditions a gas phase and a liquid phase. A jacket formed of plastics sachets (6) surrounds and is in heat transfer relationship with the outer surface of the cylinder (2). The sachets define closed compartments containing a heat release substance which is liquid at 20°C. On opening the valve (4), the non-permanent gas is delivered from the cylinder (2). The liquid phase of the non-permanet gas absorbs heat from the heat release substance which undergoes fusion. The heat release substance may be water.
