Abstract
An apparatus for supplying liquid nitrogen for a decompression device: includes a liquid nitrogen supply line extending such that high-temperature, high-pressure liquid nitrogen is introduced to a decompression device; a bypass pipe diverging from the liquid nitrogen supply line; and an expansion unit installed at the bypass pipe to evaporate the liquid nitrogen into nitrogen gas. The expansion unit is disposed to absorb heat from the liquid nitrogen in the liquid nitrogen supply line before being introduced to the decompression device.
