  • Publication number: 20110232303
    Abstract: A temperature regulation apparatus includes a dry ice module that encloses dry ice so that the module's outside surface is not hazardous to touch. Insulation, breathable material, or a combination of insulating and breathable materials, allows dry ice sublimation at a sufficiently slow rate within the attached dry ice module to control the ambient temperature in the area to be cooled. The dry ice module can be attached in a location that maximizes the dry ice cooling properties, typically at or near the top of the area to be cooled. Since sublimated carbon dioxide is heavier than normal air, it falls to the bottom of the area to be cooled and builds up. The venting placement in the dry ice module is based upon the make up of the dry ice module and the breathable materials inside of it.

  • Patent number: 7841190
    Abstract: Methods and devices for the management of cryogenic agents within analytical systems using freeze thaw valving having an expansion chamber that limits the flow of the cryogenic agent. The expansion chamber is fitted with an expansion nozzle through which a cryogen flows and a porous frit that allows the cryogen to be exhausted. The porous frit initially allows a rapid flow of cryogen into the expansion chamber. This rapid flow lowers the temperature of the expansion chamber causing fluid contents within a freeze thaw segment to freeze. As the cryogen expands into the expansion chamber and turns into a solid, the porous frit is occluded causing the rapid flow to be restricted. The restriction of the cryogen flow by the occlusion of the porous frit allows the freeze thaw valve to use significantly less cryogen. Sublimation of the cryogen trapped within the porous frit provides sufficient cooling to maintain the valve in its closed position.

  • Patent number: 6182458
    Abstract: An apparatus and method is provided for precipitating water ice or CO2 snow downwardly over a load within a shipping container or semitrailer body. The apparatus and method utilize high pressure and high velocity fog-like spray discharges of liquid CO2 and water (for forming water ice) or opposing high pressure and high velocity fog-like spray discharges of liquid CO2 (for forming CO2 snow) for intimate commingling in an elevated area of the container or semitrailer body. The commingling fog-like jet discharges of water and liquid CO2 cause water ice precipitation downward over a load within the container or semitrailer body and are capable of producing ice at a rate (poundage) equal to generally 96% of the rate (poundage) at which liquid CO2 is consumed in forming the water ice. Further, the opposing and commingling high pressure and high velocity fog-like spray discharges of liquid CO2 cause CO2 snow to form and to precipitate downward over an associated load.

  • Patent number: 6067814
    Abstract: The invention concerns a method for cooling containers, wherein cold is generated in a primary circuit containing a cooling medium. Cold is supplied via a heat exchanger to a cold carrier in a secondary circuit. The secondary circuit's cold carrier flows into a container through pipes with releasable couplings, transferring cold to the container through a heat exchanger. Cold is stored in one or more cold stores in the secondary circuit, in or outside the container, for subsequent emission in the event of an interruption in the cold supply. The invention also concerns a cooling system for implementation of the method.

  • Patent number: 5953928
    Abstract: A transportable container for carrying refrigerated products in frozen (sub zero Fahrenheit (below -18.degree. C.) or refrigerated (for example, 40.degree. F. (4.degree. C.) temperatures includes a structural container having an insulated outer shell with an access doorway. The upper portion of the container includes a tray or drawer in which are disposed a pair of spaced apart canisters containing liquid refrigerant (CO.sub.2, for example). A gas or liquid feeder tube penetrates each bottle and communicates with an on/off valve. A feeder tube can draw liquid to dispense for cooling, or it can release gas and pressure within the canister to boil the CO.sub.2. When CO.sub.2 reaches its boiling point, the canister, its bracket, and the cold plate reach very cold temperatures to cool the cargo area through conduction. The gas is released through an injection nozzle into the cargo holding area. A temperature regulator valve dispenses CO.sub.
