District community cooling system using LNG cold thermal energy

摘要

The present invention is a cold heat exchanger, such as air that is configured to convert the cold heat energy generated in the process of converting liquefied natural gas of -162 ℃ into natural gas at room temperature to a low temperature refrigerant medium by heat exchange action with heat medium such as air or cooling water Thermal medium storage tank for purifying and storing the thermal medium, large refrigerant storage tank and storage device for storing and delivering low temperature refrigerant, heat exchanger for vaporizing liquid natural gas into natural gas, and low temperature refrigerant using natural gas. Gas cooler for additional production, medium coolant storage tank for storing low temperature coolant transported along the cold heat pipe in the area near demand, and small coolant circulation tank for efficient supply of low temperature coolant according to the increase or decrease of cooling demand Low by air conditioner, filter and blower installed to measure cold energy consumption By supplying warm cooling medium, noise and vibration generated by indoor air conditioner can be eliminated and installation space can be eliminated, and ozone layer destruction caused by the use of freon refrigerant, greenhouse gas caused by electricity use, and also side effects such as global warming and climate change are fundamental. In particular, the present invention relates to a regional group cooling energy system using liquid natural gas cold heat that can be expected to save resources and protect the environment by recovering the cold heat energy of liquefied natural gas discarded in the sea and using it as a cooling energy resource.
