The invention relates to a cold energy use system and method for LNG power ship cold storage, and belongs to the technical field of LNG power ship cold storage cold energy use. The system comprises astorage tank, a cold energy recycling heat exchanger, a heating heat exchanger and a buffer tank. The buffer tank is connected with an engine through a pipeline, a high-temperature cold storage tank,the cold energy recycling heat exchanger and a low-temperature cold storage tank are mounted, a cold energy recycling circulation is formed, a secondary refrigerant is subjected to cold energy releasing to return to the high temperature cold storage tank from the low temperature cold storage tank, cold energy use circulation is formed, released cold energy in the LNG gasification process is effectively used, through the system control, the temperature of the secondary refrigerant in the low-temperature cold storage tank is always kept within the set temperature range for space cold storage usewhile engine power needs are met, the total system only uses one secondary refrigerant, and the system is clear in design, easy to maintain and low in cost.

    本发明涉及一种LNG动力船舶冷藏用冷能利用系统及其方法,属于LNG动力船舶冷藏冷能利用技术领域,包括储罐、冷能回收换热器、加热换热器和缓冲罐,缓冲罐通过管线连接发动机,通过设置高温储冷罐、冷能回收换热器和低温储冷罐,形成冷能回收循环;通过将载冷剂从低温储冷罐进行冷能释放回到高温储冷罐,形成冷能利用循环,有效利用了了LNG气化过程中所释放冷能,在满足发动机动力需求的同时,通过系统控制使低温储冷罐内载冷剂的温度始终保持在设定的温度范围,以供空间冷藏使用,且全系统只使用一种载冷剂,系统设计清晰,维护简单、成本低。
