摘要:
A system for cooling one or more discrete superconducting devices wherein a primary refrigerator subcools cryogenic liquid for desubcooling in the devices and subsequently resubcools this liquid in a recirculation loop, and additional cryogenic liquid is maintained in a subcooled condition within a reserve storage container by diversion of some of the refrigeration generated by the primary refrigerator into the reserve storage container.
摘要:
A system for providing cooling to cable such as superconducting cable which employs at least one cryocooling station or consolidated cryocooler/pumping station which processes coolant involving multiple cable lengths.
摘要:
A cryogenic tank system wherein cryogenic liquid from a primary cryogenic liquid storage tank is subcooled by refrigeration generated by a cryocooler, passed into an auxiliary tank, pressurized, and returned to the primary storage tank, preferably by way of the cryocooler, thus cooling the storage tank contents and reducing the pressure within and the vapor losses from the storage tank.
摘要:
A superconducting cable cooling system, wherein coolant continually provides cooling to superconducting cable, comprising a plurality of nodes within a superconducting cable network and a plurality of legs of superconducting cable which interconnect each of the nodes of the superconducting cable network.
摘要:
A system for the cryogenic preservation of biological material having a dedicated cryocooler integrated with an insulated vessel and preferably a membrane separator which processes feed air for supplying gaseous nitrogen into the insulated vessel for condensation by refrigeration provided by the dedicated cryocooler.
摘要:
A pulse tube system for generating refrigeration for uses such as in magnetic resonance imaging systems wherein an oil-free compressor operating at a higher frequency generates pulsing gas which undergoes a frequency reduction and drives the pulse tube system at a more efficient lower frequency.
摘要:
An air compression system and method for an air separation plant in which air is compressed in a series of compression stages and a temperature swing adsorption unit adsorbs water vapor and carbon dioxide. The temperature swing adsorption unit is situated at a location of the compression stages such that air pressure upon entry into the adsorbent beds is between about 400 psia and about 600 psia. Each of the adsorbent beds of the unit have a minimum transverse cross-sectional flow area that will set the air velocity of the air to a level below that at which adsorbent bed fluidization would occur. Such operation allows fabrication costs of the adsorbent beds to be reduced because less adsorbent and smaller adsorbent beds are required while power consumption will be at a minimum.
摘要:
A system for cooling a power transformer wherein cryogen in liquid or solid form is sprayed into a vaporizer or directly onto a power transformer radiator and the vaporizing and/or sublimating cryogen cools a cooling fluid within the vaporizer or cools the radiator directly to provide cooling to the power transformer.
