FIELD: protracted storage of liquefied gases. SUBSTANCE: closed nitrogen loop of unit includes Stirling cryogenic machine, Dewar flask, high- pressure pump, condensing coil and throttle valve. Condensing coil is located in heat exchanger made in form of heat-insulated expansion reservoir. Liquefied gas vapor recondensation loops run through heat exchanger. Each loop has heat-insulated reservoir for storage of liquefied gas, safety and throttle valves, adjusting valves fitted before and after heat exchanger and check valve. EFFECT: enhanced efficiency of systems; low expenses required for storage and use of liquefied gases. 1 dwg
