摘要： A method of operating a hybrid temperature control system. The method provides an evaporator, which has a discharge line, a supply line, and a evaporator coil. The evaporator coil is in fluid communication with the discharge line and the supply line. The method also provides a microprocessor, which regulates a supply of a heat absorbing fluid to the evaporator. The method further couples a sensor module to the microprocessor. The sensor module is near the evaporator, senses a temperature of a gas exiting the evaporator, and sends a temperature to the microprocessor. The method also turns off the supply of the heat absorbing fluid to the evaporator when the microprocessor determines that the temperature of the gas exiting the evaporator reaches a predetermined temperature.

摘要： A method of temperature control in a cryogenic temperature control apparatus. The method includes operating the cryogenic temperature control apparatus in a first mode, and delivering a first flow rate of cryogen from a storage tank to an evaporator coil in the first mode. The cryogenic temperature control apparatus is operated in a second mode after operating the cryogenic temperature control apparatus in the first mode for a predetermined time duration. A second flow rate of cryogen that is lower than the first flow rate is delivered to the evaporator coil in the second mode.

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.
