This technology focuses on recovering the cold energy (approximately 883 kJ/kg) released during the regasification of LNG to improve utilization efficiency and reduce energy consumption. Following the principle of cascade utilization, the cold energy from LNG regasification (-162 ℃ to 27℃)is applied in stages to fields such as low-temperature quick-freezing storage (-60℃), frozen storage (-35℃ to -18℃), fruit and vegetable pre-cooling, and air conditioning systems. It can also be applied to temperature difference power generation, air separation, and dry ice production.
