1results about How to "Solve effective use" patented technology

The utility model relates to energy utilization technical field, concretely relates to a cold quantity utilization system of liquid nitrogen vaporization. The cold quantity utilization system includes: liquid nitrogen vaporization mechanism, total heat exchange mechanism, cold quantity utilization mechanism, be suitable for with first heat exchange side connection, supplementary heat exchange mechanism, be suitable for with cold quantity utilization mechanism carries out heat exchange, auxiliary heat exchange mechanism, be suitable for with first heat exchange side connection, the cold quantity utilization system has first state that first heat exchange side with cold quantity utilization mechanism connects, second state that first heat exchange side, supplementary heat exchange mechanism simultaneously with cold quantity utilization mechanism connects, and third state that first heat exchange side simultaneously with cold quantity utilization mechanism, auxiliary heat exchange mechanism connects. When cold quantity normally provides, adopts first state, when cold quantity is insufficient, adopts second state, when cold quantity is too much, adopts third state, thereby can effectively utilize the cold quantity of liquid nitrogen vaporization time variable condition.
