摘要： Apparatus and methods for improving efficiency of a temperature conditioning system which employs a cryogenic liquid. A vapor powered ventilation motor is normally powered by vapor from the low pressure end of the evaporation coils. However, supplemental vapor is provided at start-up to provide immediate ventilation. In addition, vapor which bleeds off valves is cycled through the vapor powered motor or used to maintain a slight positive pressure when the system is shut down.

摘要： Both an apparatus and method are provided for vaporizing a liquid cryogen and super heating the resulting vapor into a heated gas. The apparatus includes a combustion-type heat source which may burn a fuel such as propane that generates water-containing combustion gases, and a vaporizer coil having an inlet conduit for receiving a flow of a liquid cryogen, such as liquid carbon dioxide, and an outlet conduit for expelling vaporized cryogen. An annular casing surrounds but is spaced apart from the vaporizer coil. The casing isolates the vaporizer coil from contact with water-containing combustion gases generated by the heat source, thereby preventing the formation of unwanted water and ice on the coil, while at the same time transferring heat from these gases to the coil by thermal radiation. A superheating coil is serially connected to the vaporizer coil to further heat the vaporized cryogen. Both the vaporizer coil and super heater coil are compactly configured and disposed within a heat-insulating housing for minimizing heat losses. The device is particularly well adapted for use as a defroster or a heater in a mobile cryogenic refrigeration system.

摘要： Air conditioning and refrigeration apparatus for controlling the temperature of a conditioned space to a predetermined temperature band adjacent to a predetermined set point temperature via cooling and heating cycles utilizing a supply of pressurized cryogen. A cryogen driven motor drives a fan and an alternator. The alternator provides control voltage for operating electrical control devices which select a heating cycle, or a cooling cycle, as required, and which control the flow of cryogen during the selected cycle. Electrical load on the alternator, and thus a load on the vapor driven motor, is minimized to maintain air delivered by the fan to the conditioned space at a level which provides a substantially uniform air flow and temperature throughout the conditioned space. A cryogen flow control valve is motor controlled and only requires electrical energy when a change in the cryogen flow rate is desired. Heating and cooling cycle selecting valves require no electrical energy during a cooling cycle, and very little electrical energy during a heating cycle, as cryogen pressure is utilized to shift the heating and cooling cycle selecting valves when a heating cycle is desired.

摘要： Both an system and method are provided for transferring liquid carbon dioxide from a storage tank pressurized at 300 psi to a truck-transportable tank pressurized at about 110 psi. The system includes an inlet conduit having a hose portion connected between the storage and transportable tanks for conducting a flow of liquid carbon dioxide therebetween, and a vent hose connected to the transportable tank for venting gaseous carbon dioxide. Pressure regulators are connected to the inlet and vent hoses, respectively. In operation, the pressure regulator connected to the inlet conduit reduces the pressure of the flow of liquid carbon dioxide entering the transportable tank from 300 psi to 175 psi, while the pressure regulator connected to the vent conduit maintains a back pressure of 110 psi in the transportable tank while the allowing the venting of gaseous carbon dioxide. Automatic shut-off and purging mechanisms are provided for shutting off the flow of liquid carbon dioxide when the transportable tank is filled, and purging the inlet hose. A muffler is connected to the outlet of the vent hose for reducing the noise associated with the venting of gaseous carbon dioxide. The system allows an operator to easily and automatically fill a transportable cryogenic storage tank with liquid carbon dioxide with a minimum amount of waste and noise.

摘要： A rotary vane motor for efficiently extracting mechanical energy from an expanding gas at low rotational speeds is provided. The motor includes a housing having a cylindrical enclosure, a rotor having a plurality of radially oriented slots, a plurality of vanes slidably movable in the slots, a shaft for rotatably mounting the rotor in an eccentric position within the housing enclosure, and a slidable connection between the rotor and the shaft for equilibrating close clearances between the rotor and the side edges of the vanes and the inner surfaces of the housing to minimize inefficiencies due to blow-by and friction. Additionally, the materials forming the rotor, the vanes, and the housing are all selected to have the same thermal coefficient of expansion so that the vanes tightly interfit within their respective slots and the sealing surfaces of the housing over a temperature range spanning the cryogenic temperatures associated with the prefeffed drive gas, and maximum ambient temperatures. Finally, gas conducting structures in either the rotor or the vanes are provided for admitting a portion of the drive gas to the inner edges of the vanes to radially push the outer edges into tight sealing engagement with the inner surfaces of the housing.

摘要： A refrigeration system, which conditions the air of a conditioned space via heating and cooling cycles, includes a heat exchanger and, in a first embodiment, heat pipes. A cryogen is circulated through the heat exchanger during a cooling cycle. During a heating cycle the flow of cryogen is terminated and heat is transferred into the heat exchanger via the heat pipes. In another embodiment, the temperature of evaporation of a liquid cryogen in the heat exchanger is selected according to the desired temperature of the conditioned space, via selectable cryogen flow paths which provide different pressures and thus different evaporation temperatures. Vaporized cryogen drives a motor connected to a fan which circulates air between the conditioned space and heat exchanger. In still another embodiment, the mass flow rate of liquid cryogen is controlled as a function of the degree of superheat in evaporated cryogen exiting the heat exchanger, and as a function of a predetermined floor temperature of conditioned air discharged into the conditioned space.

摘要： A refrigeration system associated with a conditioned space to be controlled to a predetermined set point temperature via heating and cooling cycles. The refrigeration system includes a fluid flow path through which a predetermined fluid is circulated. The fluid flow path includes first, second and third heat exchangers. The first heat exchanger is disposed to condition air of the conditioned space, the second heat exchanger is in heat exchange relation with cryogenic cooling apparatus, and the third heat exchanger is in heat exchange relation with heating apparatus. The first and second heat exchangers are interconnected when the conditioned space requires a cooling cycle, and the first and third heat exchangers are interconnected when the conditioned space requires a heating cycle. Cryogen of the cryogenic cooling apparatus is thus not expended to heat the conditioned space, nor used for defrosting purposes.

摘要： Methods and apparatus for controlling the temperature of a conditioned space to a predetermined set point temperature, utilizing a supply of cryogen in liquid and vapor states. The two states are drawn from the supply in two separate flow paths. The liquid cryogen is vaporized in a heat exchanger, and the two flow paths are then combined. The combined cryogen is used to drive a vapor motor connected to a fan, with the fan moving air between the conditioned space and the heat exchanger. Heat is applied to the cryogen as required to hold the set point temperature or to defrost the heat exchanger. In a preferred embodiment, the cryogen is added to a first vessel at the pressure provided by ground support apparatus, and expanded into a second vessel as a function of system conditions, to provide the supply of cryogen in both the liquid and vapor states.
