Using liquefied gas, it is possible to reliquefy low-temperature liquefied gas with a high saturation temperature. Therefore, less power is required to maintain a constant pressure in the low temperature liquefied gas storage tank, and the operating cost of the device is reduced. Furthermore, since the refrigeration equipment 5 is not required for low-temperature liquefied gas with a high saturation temperature, the equipment cost is also reduced.
