摘要： Efficient two-phase refrigerant mixture distribution is accomplished in a falling film evaporator by use of a refrigerant distributor disposed internal of the evaporator shell which overlies the evaporator tube bundle and which internally causes said two-phase refrigerant mixture to be made available along essentially the entire length and across essentially the entire width of the tube bundle prior to the delivery of the refrigerant out of the distributor.

摘要： A falling film evaporator for use in a vapor compression refrigeration chiller preferably employs a two-phase refrigerant distributor that overlies the tube bundle in the evaporator shell. The tube bundle defines at least one vapor lane which facilitates the conduct of refrigerant vapor from the interior of the tube bundle to the exterior thereof in a manner which does not substantially affect the vertically downward flow of liquid refrigerant through the tube bundle and across the vapor lane.

摘要： Oil cooling is accomplished in a refrigeration chiller by flowing hot oil into heat exchange contact with liquid refrigerant which is sourced from the chiller's condenser and returned thereto. The rejection of heat from the oil to the refrigerant in an oil-cooling heat exchanger causes vaporization of the refrigerant and, in turn, creates a density difference in the refrigerant flowing from the condenser and refrigerant in and downstream of the oil-cooling heat exchanger. This density difference is responsible for inducing and maintaining refrigerant flow through the heat exchanger for oil cooling purposes.

摘要： Compressor lubricant in a screw compressor-based refrigeration system is cooled by directing the lubricant from the system oil separator to an oil-cooling heat exchanger disposed in the lower portion of the system condenser where it is bathed in condensed system refrigerant. Parasitic capacity losses with respect to the compressor lubricant cooling process are thereby avoided.

摘要： A liquid/gas bypass line bypasses an expansion device of a refrigeration apparatus. An inlet of the bypass line is connected slightly above the bottom of a condenser so that it can pass either liquid refrigerant or vaporous refrigerant, depending on the level of liquid refrigerant in the condenser. The other end of the bypass line is connected to discharge into the evaporator, bypassing the expansion device. The bypass line functions as a conventional hot gas bypass during low load conditions when the level of liquid refrigerant is below the line's inlet. When the level rises above the inlet, often occurring when the condenser coolant temperature is low and the compressor is fully loaded, the bypass line returns excess accumulated liquid refrigerant to the evaporator. Maintaining the proper levels of liquid refrigerant in both the condenser and the evaporator not only provides the most effective use of their heat transfer surfaces, but also promotes the proper return of oil to the compressor.
摘要翻译： 液体/气体旁通管线绕过制冷装置的膨胀装置。 旁路管路的入口稍微高于冷凝器的底部，使得其可以通过液体制冷剂或蒸汽制冷剂，这取决于冷凝器中的液体制冷剂的水平。 旁路管线的另一端连接到排放到蒸发器中，绕过膨胀装置。 当液体制冷剂的液位低于管线入口时，旁路管线在低负荷条件下用作传统的热气旁路。 当水平高于入口时，通常在冷凝器冷却剂温度低并且压缩机满载时发生，旁路管线将多余的液体制冷剂返回到蒸发器。 在冷凝器和蒸发器中保持适当水平的液体制冷剂不仅提供了它们的传热表面的最有效的使用，而且还促进了油到压缩机的适当返回。

摘要： A vehicle suspension has axle end portions each pivotally coupled to an associated leaf spring and thereby to an associated supporting vehicle frame rail. Control rods are pivotally coupled to the axle at locations below the leaf spring pivots. Desirably, one of such control rods is pivoted to the axle at a location above the wheel axis and the other of such control rods is pivotally coupled to the axle at a location below the wheel axis. A steering mechanism for steering the steerable wheels of a tandem axle includes first and second steering gears mounted to a common frame rail and driven by a single mechanical coupling such as a T-miter box. These steering gears may control respective steering gears at the opposite side of the vehicle.

摘要： A falling film evaporator includes a flow distributor for uniformly distributing a two-phase refrigerant mixture across a tube bundle. The flow distributor includes a stack of at least three perforated plates each of which are separated by nearly full-width, full-length gaps or chambers. The flow distributor may also include a suction baffle and/or a distributor baffle. The distributor baffle extends downward to provide a hairpin turn past which refrigerant travels before exiting the evaporator. This directional change helps separate liquid from a primarily gaseous refrigerant stream. The suction baffle has various size openings to ensure that the flow rate of refrigerant through the hairpin turn is generally uniform and is maintained low enough to ensure liquid disentrainment over and along the length of the tube bundle within the evaporator.

摘要： A spring movement limiting device that limits lateral shift of a spring in a vehicle suspension along a vehicle axle direction includes a first element and a second element. The first element is coupled to the axle and to the spring. The second element is separate from and engageable with the first element. The second element is fixed at a predetermined position relative to the vehicle axle. Engagement between the first element and the second element limits the first element and spring from movement in the vehicle axle direction.

摘要： Liquid refrigerant produced in the condenser of a refrigeration system is directed into an expansion device. The expansion device throttles the high pressure liquid refrigerant into the compressor drive motor housing of the compressor assembly within the refrigeration system. Upon entering the motor housing a first portion of the liquid refrigerant flashes into gas at a pressure intermediate compressor suction and discharge pressure. The portion of refrigerant which remains in the liquid state is directed into a jacket surrounding the stator of the compressor drive motor. As the jacket fills with liquid refrigerant, a portion of the refrigerant is directed through passages in the motor stator into contact with the motor rotor. Liquid refrigerant overflowing the jacket and flowing out the ends of the motor through the gap between the rotor and stator drains to the lowermost portion of the motor housing from where it is directed to a second expansion device. Flash gas within the drive motor housing, together with gas generated by motor cooling, is directed out of the motor housing and into the compression chamber of the compressor assembly in order to increase the capacity and efficiency of the refrigeration system.
