摘要： An apparatus and method for spraying a cryogen in which a heat load is sprayed with a cryogen from one or more spray nozzles within a spray zone. A heat conductive element is positioned below the article and is provided with a surface sized to catch the liquid content of the cryogen that has been oversprayed, thereby to vaporize the overspray through direct heat transfer with the conductive element. In another aspect the present invention provides an apparatus and method in which a flow network a flow of a liquid cryogen is divided into first and second subsidiary streams. The second subsidiary stream is vaporized within a branch of the network and then mixed back into the first subsidiary stream to produce a two phase flow of the cryogen. The cryogen is then sprayed as the two phase flow. The flow rate of the second subsidiary stream can be controlled with a proportional valve to adjust the quality of the cryogen being sprayed so that pooling of overspray on said heat conductive element is inhibited.

摘要： A refrigeration device in which a heat load is refrigerated within a refrigeration chamber. Refrigerant is supplied, preferably, from a supply of turboexpanded air employing a compressor to compress the air and a turboexpander to expand the compressed air to a low temperature. A venturi-like device such as an ejector circulates the refrigerant within a circulation path within the refrigeration chamber so that heat is transferred from the heat load to the refrigerant. An incoming mass flow rate of the refrigerant is delivered to a high pressure inlet of the venturi-like device and a recirculation mass flow rate of the refrigerant is received within the low pressure inlet from the circulation path after the refrigerant has heat transferred thereto. A high pressure outlet discharges a mixture of the refrigerant that comprises the incoming and recirculation mass flow rates to the circulation path and prior to the heat load. Controls are provided to either control the recirculation mass flow rate of the refrigerant or a by-pass flow of refrigerant in a by-pass line communicating between the high pressure inlet and outlet. Such control acts to control circulation within the circulation path.

摘要： An article is formed in a mold by blowing a hot plastic material with a blowing gas. A cooling fluid is introduced into the article to cool the article and allow its removal from the mold. A warmed gaseous form of a cryogen is added to a pressurized liquid form of the cryogen to form the cooling fluid by introducing the pressurized form of the cryogen into a jet pump and drawing the warmed gaseous form of the cryogen in the pressurized liquid form of the cryogen. The resultant cooling fluid circulates through the article by being introduced into the article and discharged from the article by two or more blow pins. Part of the discharged cooling fluid is then recovered in a storage tank. The cooling fluid, which after cooling the article is composed of the warmed gaseous form of the cryogen, is then drawn from the storage tank into the jet pump during formation of the cooling fluid. Additionally, the blowing gas can comprise cooling fluid formed in the manner outlined above. Alternatively, the blowing gas can comprise the warmed gaseous form of the cryogen recovered from the article.

摘要： The present invention relates to a cryogen delivery apparatus and method for delivering a flowing cryogen with a regulated cooling potential. The apparatus includes a pressure vessel for receiving a liquid form of the cryogen. A liquid-vapor interface is maintained within the pressure vessel so that a gaseous form of the cryogen having a low cooling potential is situated above the liquid-vapor interface and a liquid form of the cryogen having a high cooling potential is situated below the liquid-vapor interface. An outlet conduit is provided for delivering the gas and liquid forms of the cryogen from the pressure vessel. The conduit has a moveable end section located within the pressure vessel. When the moveable end section is oscillated above and below the level of a liquid-vapor interface, a two-phase flow of cryogen is delivered comprising the pure gaseous and liquid forms of the cryogen. A timing control circuit is provided to selectively regulate the time intervals that moveable end section is above and below the liquid-vapor interface during each period of oscillation. Such regulation in turn regulates the proportions of the gaseous and liquid forms and thus, the cooling potential contained in the delivered cryogen.

摘要： The present invention relates to an apparatus for delivery of pure gaseous and liquid forms of cryogen. The apparatus includes a pressure vessel for receiving a liquid form of the cryogen. A liquid-vapor interface is maintained within the pressure vessel by a liquid level detector and a cut-off valve connected to the level detector to vent the gaseous form of the cryogen to the atmosphere when the liquid form falls below a predetermined level. A heated overflow tube projects into the pressure vessel and is positioned at the predetermined level of the liquid. When the liquid rises above the predetermined level, it flowws into the overflow tube and is heated to vapor to add to the gaseous form of the cryogen within the pressure vessel. An outlet conduit is provided for delivering the gas and liquid forms of the cryogen from the pressure vessel. The conduit has a moveable end section located within the pressure vessel. When the movable end section is moved above the level of a liquid-vapor interface, the gas form of the material is delivered from the conduit; and when the moveable end section is positioned below the liquid-vapor interface, a pure liquid form of the cryogen is delivered from the pressure vessel. Movement of the moveable end section of the conduit is preferably controlled by a solenoid connected to a timing circuit.

摘要： A method and apparatus for fueling the onboard storage tank of a vehicle with liquefied natural gas. A liquid cryogen such as liquid nitrogen is fed to a condensing unit to condense natural gas present in a fueling system. Liquefied natural gas is fed into the fueling system and natural gas vapor is recovered from the onboard storage tank of the vehicle and fed to the condensing unit. When the pressure of the onboard storage tanks is sufficient, the liquefied natural gas is fed from the fueling system to the onboard storage tanks.

摘要： An apparatus for storing a multi-component cryogenic liquid in which headspace vapor in a storage tank is condensed in an external condensation tank through indirect heat exchange with liquid being vented from the storage tank. The resulting condensate can then be re-introduced into the storage tank through a pressure building circuit applied to the external condensation tank. In such manner, the pressure within the storage tank is regulated and the composition of the liquid stored within the storage tank is held with some degree of consistency. The use of an external condensation tank allows prior art cryogenic storage tanks and dewars to be retrofitted to store a multi-component cryogenic liquids.
