液化天然气接收站中的冷能在冷库设计中的利用

Cold energy utilization of liquefied natural gas terminal in refrigerating house design

简介了液化天然气(LNG)冷能的利用原理及其在冷库设计中的实例和节能效果,阐述了通过LNG冷能的介入可以简化冷库设计工艺流程,节约成本,通过分析LNG冷能与载冷剂的逆流热交换,得出LNG和库房热交换负荷,以得到冷能利用的性能系数。最后指出了冷库设计中利用LNG冷能可以达到减少投资成本,维护方便,提高经济效益的目的。

The utilization principle of liquefied natural gas（LNG） cold energy, the application of principle in refrigerating house design and the energy conservation were introduced. The LNG cold energy can simplify the processes of energy refrigerating house design and save the cost. By analyzing the countercur- rent heat exchange of LNG cold energy and secondary refrigerant, heat load of LNG and storehouse was got, and coefficient of performance can be got. It is poined out that LNG cold energy can reduce investment cost, maintain conveniently and improve economic returns in the energy refrigerating house design.
