摘要： A refrigeration system of the type having an economizer cycle is provided with a null cycle, in addition to heating and cooling cycles, without shutting a compressor prime mover down, to preserve air flow in a conditioned space. First, second and third controllable valves respectively: (1) select main and auxiliary condensers, (2) open and close a liquid line, and (3) open and close a line which provides a warm liquid to an economizer heat exchanger. The valves are controlled in at least one predetermined open/close pattern during a null cycle, and preferably in a plurality of selectable predetermined open/close patterns, to provide a null cycle at any instant which substantially matches the net heat gain or loss taking place in the conditioned space. Thus, the temperature of the served space will be more apt to remain in a null temperature range close to set point, providing smoother and more accurate control over the temperature of the conditioned space for longer shelf life of perishables stored therein. The system achieves the latter by controlling cooling circulation in the compressor oil cooler.

摘要： A refrigeration system, and method of operating same, in which an economizer heat exchanger, normally used in conjunction with an intermediate port of a refrigerant compressor to cool the main refrigerant flow from a receiver to an evaporator to enhance the refrigerant cooling cycle, is caused to function as an evaporator during a hot gas heating cycle. The economizer heat exchanger is caused to function as an evaporator by adding heat thereto during a heating cycle, and by establishing an alternate liquid line, effective during a heating cycle, which includes the economizer heat exchanger. When the compressor is driven by an internal combustion engine, engine coolant may be used to add the necessary heat to the economizer heat exchanger during a heating cycle.

摘要： A method of operating a transport refrigeration system having a six cylinder compressor and a prime mover operable at a selected one of low and high speeds, to control the temperature of a served space by cooling and hot gas heating modes. Below a set point temperature 100, system heating capacity is controlled at the low compressor speed by the step 127 of unloading compressor cylinders and the step 129 of reloading compressor cylinders. A temperature rise of the served space above a set point temperature 106 controls cooling capacity by a combination of alternative steps 135, 137, 139, 141, and 143 which may or may not change the number of loaded compressor cylinders, and may or may not change compressor speed, based upon two predetermined trigger events which relate to what the temperature of the served space does relative to time 136 and 142, a set point temperature 106, and a temperature 108 above set point which is normally associated with a change in compressor speed.

摘要： A cooling and sealing arrangement in a gas turbine engine comprises a seal assembly extending between nozzle guide vanes and combustion chamber discharge nozzles. The nozzle guide vanes have platforms having extensions which in one embodiment overlap the downstream ends of the discharge nozzles. Cooling air is supplied to the upstream edge portions of the platforms through holes in flanges on the discharge nozzles. The seal assembly defines a chamber adjacent the platform extensions which is supplied with cooling air through metering holes in the seal assembly which provides part of a boundary for a cooling air chamber, the boundary of the chamber having cooling air holes for metering cooling air into the chamber to cool the upstream portion of the nozzle guide vane outer platforms. Cooling air exits the chamber through holes in the platform extensions to film cool them.

摘要： A cooling and sealing arrangement in a gas turbine engine comprises a seal assembly (42,30) extending between nozzle guide vanes (20) and combustion chamber discharge nozzles (22). The nozzle guide vanes (20) have platforms (34,36) having extensions (34A,36A) which in one embodiment overlap the downstream ends of the discharge nozzles (22). Cooling air is supplied to the upstream edge portions of the platforms through holes (26,28C) in flanges (24,28) on the discharge nozzles (22). The seal assembly (42,30) defines a chamber (58,70) adjacent the platform extensions which is supplied with cooling air through metering holes (56,68) in the seal assembly. Cooling air exits the chamber (58,70) through holes (34B,36B) in the platform extensions to film cool them.

摘要： This invention relates to a compression refrigeration system having means for removing some of the oil refrigerant foam which is formed in a crankcase at startup. The removal of foam with entrained oil from the crankcase is to reduce the amount of oil pumped with the refrigerant through condenser and evaporator and at the same time rapidly return oil to the crankcase during startup. In one embodiment of the invention, oil refrigerant foam goes from the crankcase to a foam trap where the foam collapses, the oil drains back to the crankcase, and the refrigerant vapor is drawn to an intake of the compressor. In another embodiment, oil refrigerant foam passes to a suction accumulator where the foam collapses, refrigerant vapor is drawn to an intake of the compressor and the vapor carries droplets of separated oil to a point where they drain back to the crankcase.
摘要翻译： 本发明涉及一种压缩式制冷系统，其具有用于去除启动时在曲轴箱中形成的一些油制冷剂泡沫的装置。 从曲轴箱中去除具有夹带油的泡沫是通过冷凝器和蒸发器减少用制冷剂泵送的油量，同时在启动期间迅速将油返回到曲轴箱。 在本发明的一个实施例中，油致冷剂泡沫从曲轴箱流到泡沫陷阱，泡沫破裂，油排出回到曲轴箱，并且制冷剂蒸气被抽吸到压缩机的入口。 在另一个实施方案中，油制冷剂泡沫通过吸收储存器，其中泡沫破裂，制冷剂蒸汽被抽吸到压缩机的入口，并且蒸汽携带分离的油的液滴到它们排回到曲轴箱的点。
