  • Publication number: 20060000222
    Abstract: Liquid nitrogen is filled in a low temperature vessel; an ejector that sucks liquid nitrogen by blowing a cooling agent (liquid or gas) such as low temperature helium gas or liquid helium of pressure higher than in the space within the vessel is disposed in the vessel; the liquid nitrogen blown with the cooling agent is cooled by the cooling agent to become fine particles of solid nitrogen which fall down; and gas in a space of the vessel is discharged out of the vessel so as to maintain the pressure of the space higher than the atmospheric pressure. A gaseous phase of liquid nitrogen in an adiabatic vessel is depressurized to vaporize nitrogen in a liquid phase so that a temperature of the nitrogen is reached to the triple point of nitrogen by lowering temperature thereby and solid nitrogen is produced by keeping at the triple point, and that the produced solid nitrogen is transformed into slush by stirring the content of the adiabatic vessel.

  • Patent number: 6889520
    Abstract: The object of the invention is to provide a thermal complementary (combination of heat supply and heat discharge) system which can complement heat without the restriction of area of a region to be supplied with heat. An endless multiplex helical loop is formed to complement the heat produced in a region such as plants and regional facilities on a reciprocal basis, and the water is not circulated forcibly but achieves heat transfer in the helical loop. Liquid or slurry-like water is sealed in the annular endless channel (endless loop) without forcibly circulated. Therefore, loop diameter of the annular endless channel, that means the area of the region, is not limited. The water forms temperature zones in the endless helical loop, the temperature being different per each component loop. Distributed cryogenic sources and thermal sources are thermally connected to said multiplex helical loop so that heat (i.e. water) can be taken in or discharged to or from said cryogenic or thermal sources.
