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 rotary vane motor adapted to operate at low rpm with a source of cryogenic pressurized gas. The rotary vane motor includes a housing having a cylindrical opening connected to a primary inlet assembly and an outlet assembly, a first and second end plate attached at opposite sides of the cylindrical opening, a rotor having a plurality of radially oriented, a plurality of vanes movable within the slots and a shaft for rotatably mounting the rotor in an eccentric position within the cylindrical opening. The first end plate includes a slot positioned for fluid communication with at least one of the rotor slots so as to direct pressurized fluid from a secondary inlet assembly. In the preferred embodiment, each of the plurality of vanes includes grooves for facilitating release of trapped fluid. During use, pressurized gas from the secondary inlet assembly forces the vanes radially outward relative to the rotor slots upon communication with first end plate slot such that any friction-causing problems are overcome.

摘要： A two-stage rotary vane motor is provided that is particularly efficient for use in cryogenic refrigeration systems where the mass flow rate of the drive fluid (which may be expanding cryogen gas) varies substantially. The two-stage rotary vane motor includes a housing enclosure having first and second fluid chambers, each with their own inlets for receiving pressurized cryogen, and first and second rotors rotatably mounted within the chambers by means of a shaft assembly having an output end. In operation, when the mass flow of the drive fluid is high (350 pounds per hour), fluid is admitted through the inlets of both the chambers of the housing enclosure to drive both of the rotors. However, when the mass flow of the drive fluid drops to a low level (i.e., 100 pounds per hour), expanding cryogen is admitted only through the second chamber of the housing enclosure to drive only the second rotor. An overrunning clutch may be used to engage and disengage the first rotor from the shaft assembly in coordination with the admission of drive fluid through both or only one of the housing inlets.
摘要翻译：提供了两级旋转叶片电动机，其特别有效地用于低温制冷系统，其中驱动流体（其可膨胀的致冷剂气体）的质量流量基本上变化。两级旋转叶片马达包括具有第一和第二流体室的壳体壳体，每个流体室具有用于接收加压制冷剂的各自的入口，以及通过具有输出端的轴组件可旋转地安装在腔室内的第一和第二转子。在操作中，当驱动流体的质量流量高（350磅/小时）时，通过壳体外壳的两个腔室的入口允许流体驱动两个转子。然而，当驱动流体的质量流量下降到低水平（即每小时100磅）时，仅通过壳体外壳的第二腔室仅允许扩张的冷冻剂仅驱动第二转子。可以使用超越离合器来将第一转子与轴组件接合并且与驱动流体通过两个或仅一个壳体入口协调地脱离啮合。

摘要： A transport refrigeration system including a compressor, a prime mover for the compressor, a condenser, and an evaporator blower assembly. The evaporator blower assembly includes a shaft driven by the prime mover, a first blower fixed to the driven shaft, a second blower journaled for rotation about the driven shaft, and a clutch for coupling and decoupling the first and second blowers. The volume of air moved through the evaporator and into the conditioned space or cargo area is thus selectable based upon need of the transport refrigeration system, without the necessity of changing the speed of the prime mover. The resulting savings in power realized when only one blower is being driven is automatically translated into fuel savings and/or increased cooling capacity.

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.
