摘要： A system of parallel compressors for compressing fluids miscible with oil. Means are provided for internally separating each compressor connected in parallel into a discharge chamber, a suction chamber, and a crankcase chamber, the chambers of each compressor being independent of one another. The crankcase chambers are connected in oil and gas flow communication with one another. A suction manifold is connected to the suction chambers, and each crankcase chamber is equalized with suction pressure. A discharge manifold is connected to the discharge chambers. Means for separating the oil from compressed fluids leaving the discharge chambers and returning the oil so separated to the crankcase chambers are also provided.

摘要： An improvement in a recirculating refrigeration system which includes an "economizer" compressor. The economizer compressor is in a flash gas handling sub-system which receives flash gas from the primary system at a substantially higher input pressure than the primary compressor. As a result the load on the primary system compressor is reduced. The overall effect is a more efficient system, using less power.

摘要： In a refrigeration system comprising a refrigerant circuit, a heat exchanger, an expansion element which, in the active state, cools the entire mass flow of the refrigerant by expansion and thereby produces a main mass flow consisting of liquid refrigerant and an auxiliary mass flow consisting of gaseous refrigerant which enter an intermediate pressure accumulator, at least one normal refrigerating stage which expands a normal refrigerating mass flow in at least one normal refrigerating expansion unit to a low pressure and thereby makes refrigerating capacity available for normal refrigerating purposes, a refrigerant compressor unit which compresses the normal refrigerating mass flow from low pressure to high pressure, and a parallel compressor which, in a parallel compression mode of operation of the refrigerant circuit, sucks in refrigerant from the intermediate pressure accumulator and compresses it to high pressure, it is proposed that, in order to increase the efficiency, the power of the parallel compressor be controlled by a control system, that the control system determine at least one reference variable representing a load state of the refrigerant circuit, that the control system determine a set intermediate pressure value on the basis of the at least one reference variable at least in a parallel compression mode of operation, and that the control system regulate the intermediate pressure in accordance with the set intermediate pressure value at least in the parallel compression mode of operation.

摘要： A cooling system has a cabinet and a plurality of separate cooling stages including an upstream cooling stage and a downstream cooling stage. At least the upstream cooling state is a variable capacity cooling stage. Each cooling stage has a cooling circuit. Evaporators of the cooling circuits are arranged in the cabinet so that air passes over them in serial fashion. A controller when a Call for Cooling first reaches a point where cooling is needed, operating the upstream cooling circuit to provide cooling and not the downstream cooling circuit. When the Call for Cooling has increased to a second point, the controller additionally operates the downstream cooling circuit to provide cooling. The cooling capacity at which the upstream cooling circuit is being operated is less than its full capacity when the Call for Cooling reaches the second point.

摘要： An expander-integrated compressor is provided and includes: a motor; a compressor connected to an output shaft of the motor; an expander connected to the output shaft of the motor; a non-contact bearing disposed between the compressor and the expander; a casing; and an extraction line being in communicated with a region between the compressor and the expander in the internal space of the casing and extracts, from the region, the leakage fluid from the compressor side toward the expander side in the casing and to send the leakage fluid to a fluid line connected to the intake side or the discharge side of the compressor outside the casing. The casing seals the region from outside of the casing, thus the flow of the at least a part of the leakage fluid through the extraction line is the only flow of fluid between the region and the outside of the casing.

摘要： The present invention provides a capacity-control refrigeration cycle device capable of efficiently vary capacity, and in any of a full operation mode in which capacity of the refrigeration cycle device is not controlled and an operation mode in which the capacity is controlled, all of refrigerants are discharged into a hermetic container 1 and then, the refrigerants pass through a discharge path 11 and are guided to outside of the hermetic container 1. After a refrigerant and oil are sufficiently separated in the hermetic container 1, the refrigerant is discharged to outside of the hermetic container 1. Therefore, efficiencies of a condenser 300 and an evaporator 600 are not deteriorated. Since it is possible to reduce an amount of oil taken outside of the hermetic container, it is possible to stably secure oil in an oil reservoir 22, and to prevent bite of parts of a compressing mechanism and to prevent abnormal wearing.
