The present invention relates to a refrigerating system using liquid nitrogen. The objective of the present invention is to facilitate a low-temperature storage of food by having the refrigerating system for spraying liquid nitrogen through the spraying nozzles have a quick cooling effect when an internal temperature of a refrigerating car, a refrigerating ship, or a cold storage rises at a set temperature or higher. The refrigerating system to refrigerate goods stored in a refrigerating room of the refrigerating car, the refrigerating ship, or the cold storage comprises: a pressure container installed in one side of an inside or an outside of the refrigerating room, and charged with liquid nitrogen; an opening and closing valve installed in an outlet of the pressure container, opened and closed by an on-off control to spill or block the charged liquid nitrogen; a pipeline fixated on the inner ceiling and wall of the refrigerating room from the opening and closing valve at a predetermined pattern; the spraying nozzles installed in the pipeline at a constant interval, spraying the liquid nitrogen spilt via the opening and closing valve from the pressure container by the on-control of the opening and closing valve into the refrigerating room; one or more temperature detection sensors installed inside the refrigerating room to detect the internal temperature of the refrigerating room; and a control part to control the on and off of the opening and closing valve in accordance to the internal set temperature of the refrigerating room through signals detected by the temperature detection sensors.

    본 발명은 액화질소를 이용한 냉동시스템에 관한 것으로, 냉동탑차나 냉동선박 및 냉동보관창고 등의 내부 온도가 설정 온도 이상으로 올라가는 경우 분사노즐을 통해 액화질소를 분사하는 냉동시스템을 구성함으로써 보다 빠른 시간에 냉각효과가 이루어질 수 있도록 하여 식품의 저온 보관이 용이하도록 함에 그 목적이 있다. 이를 위해 구성되는 본 발명은 냉동탑차나 냉동선박 또는 냉동창고의 냉동실에 보관되는 물품을 냉동시키는 냉동시스템에 있어서, 냉동실의 내부 또는 외부 일측에 설치되어지되 내부에는 액화질소가 충진되는 압력용기; 압력용기의 출구단에 설치되어지되 온/오프(on/off) 제어에 의해 개폐되어 충진된 액화질소를 유출 또는 차단시키는 개폐밸브; 개폐밸브로부터 냉동실의 내부 천장과 벽면에 일정 패턴으로 설치 고정되는 배관라인; 배관라인에 일정 간격으로 설치되어 개폐밸브의 온(on) 제어에 의해 압력용기로부터 개폐밸브를 경유하여 유출되는 액화질소를 냉동실의 내부에 분사하는 분사노즐; 냉동실의 내부에 설치되어 하나 이상 설치되어 냉동실 내부의 온도를 감지하는 온도감지센서; 및 온도감지센서에 의해 감지된 신호를 통해 냉동실 내부의 설정 온도에 따라 개폐밸브를 온/오프(on/off) 제어하는 제어부를 포함한 구성으로 이루어진다.
