  • Patent number: 5921091
    Abstract: A cryogenic freezing method uses a mixture of liquid nitrogen and liquid oxygen in amounts approximating the composition of atmospheric air to freeze food products. The mixture preferably includes 18% to 25% oxygen and the balance nitrogen, with small amounts of residuals which are commonly found in air. The present invention involves replacing a liquid carbon dioxide or liquid nitrogen cooling medium which is used in known cryogenic freezers with a liquid nitrogen and liquid oxygen mixture. The liquid nitrogen and oxygen mixture can be used according the present invention in many of the known freezers using liquid carbon dioxide or liquid nitrogen as a cooling medium, including tunnel freezers, spiral freezers, and immersion freezers. The use of a liquid nitrogen and liquid oxygen mixture improves the efficiency of a freezer because the cold vapors are not exhausted from the freezer. In addition, the leakage of vapors from the freezer into the room air will not create unsafe conditions for workers.

  • Patent number: 5706663
    Abstract: Mixed refrigerants provide refrigeration at cryogenic temperatures with throttling cycles operating with a one-stage compressor. The refrigerants include noncondensable gases such as helium, neon, or hydrogen to increase the overall cooling capacity of a refrigeration system at the same refrigeration temperature which is attainable without such noncondensable gases. More refrigeration can be produced with existing systems at temperatures above the normal boiling point of nitrogen or argon by adding, for example, helium, than for refrigerant blends without helium. By increasing the return pressure value of the refrigeration cycle in relation to the molar percent of helium present in the refrigerant, a constant refrigeration temperature may be maintained which exhibits greater stability than prior systems operating at the same temperature without helium enrichment.

  • Patent number: 5419156
    Abstract: A regenerative sorption compressor assembly for use in a sorption compressor/refrigerator system. The regenerative sorption compressor assembly of the present invention comprises a series of sorption compressor elements connected to a flowing loop of heat transport fluid. The compressor elements are heated and cooled by the heat transport fluid. At some point in the loop the fluid path is broken and the fluid is diverted to a heat source. At another point in the loop the fluid path is broken and the fluid is diverted to a heat sink. The points at which the heating and cooling flows are diverted are switched from compressor element to element in the direction of fluid flow at such a rate that the thermal capacity rate of the fluid in the heat transport loop relative to the moving switch point is equal and opposite to the thermal capacity rate of the compressor assembly relative to the switch point.

  • Patent number: 5339649
    Abstract: First and second refrigerating circuits respectively cause first and second adsorbing bodies to alternately adsorb and release first and second coolants. In the first refrigerating circuit, when the first adsorbing body is heated, it releases the first coolant. The released first coolant is cooled, and discharged through an expansion valve so that a part of the first coolant is liquefied. The resultant latent heat of vaporization can be utilized to cool an object to be cooled. Thereafter, the first coolant is adsorbed when the first adsorbing body is cooled. In the second refrigerating circuit, when the second adsorbing body is heated, it releases the second coolant. The released second coolant is cooled by a liquefied-gas-type cooler, and discharged through an expansion valve so that a part of the second coolant is liquefied. The resultant latent heat of vaporization is utilized to cool the first adsorbing body of the first refrigerating circuit.

  • Patent number: 5255525
    Abstract: The present invention produces a cold gas stream having a constant temperature and pressure. The gas stream is obtained from two initial streams, one being a liquefied gas and the other being a gas at ambient temperature. The liquefied gas stream is combined with the warm gas stream, causing the liquid to vaporize. The two streams are combined in proportions that yield a cold gas mixture having a desired temperature. The resulting cold gas mixture is directed into an insulated container having a volume significantly larger than the volume of the conduits through which the streams flow. The container therefore acts as a buffer to reduce pressure fluctuations in the stream. A temperature equalization coil is located in the interior of the container. The coil has one open end which communicates with the interior region of the container, the other end of the coil being connected to an outlet line.

  • Patent number: 5063747
    Abstract: The present invention relates to a cryogenic Joule-Thomson refrigeration capable of pumping multicomponent gases with a single stage sorption compressor system. Alternative methods of pumping a multicomponent gas with a single stage compressor are disclosed. In a first embodiment, the sorbent geometry is such that a void is defined near the output of the sorption compressor. When the sorbent is cooled, the sorbent primarily adsorbs the higher boiling point gas such that the lower boiling point gas passes through the sorbent to occupy the void. When the sorbent is heated, the higher boiling point gas is desorbed at high temperature and pressure and thereafter propels the lower boiling point gas out of the sorption compressor. A mixing chamber is provided to remix the constituent gases prior to expansion of the gas through a Joule-Thomson valve. Other methods of pumping multicomponent gas are disclosed.
