    摘要： A centrifugal heat pump system includes a steam system with a steam supply, a steam turbine and a steam condenser connected in a steam loop; and a refrigerant system including a first compressor and a second compressor, a refrigerant condenser, and an evaporator connected in a refrigerant loop. The steam turbine includes a rotary drive shaft disposed axially and extending from a first end and a second end of the steam turbine. A sump system collects and redistributes oil or other lubricating fluid. The first compressor is coupled by a first coupling device to the first end of the steam turbine drive shaft and the second compressor is coupled by a second coupling device to the second end of the steam turbine drive shaft. The first and second compressors are connected in parallel in the refrigerant loop and controlled to share a cooling load equally.

    摘要： The normal path for the flow of oil/refrigerant being reclaimed from the cooler (12) is changed during periods of low load operation such that the oil/refrigerant mixture flows directly from the cooler (12) to the ejector (40) rather than by way of normal suction housing pass. This is accomplished by valve means (27, 28) responsive to either a pressure differential or the guide vanes position, either of which is indicative of the load condition.

    摘要： A chiller according to the present invention comprises: a compressor for compressing a refrigerant; an oil separator for separating oil and the refrigerant discharged from the compressor; a condenser for condensing the refrigerant passing through the oil separator; and expander for expanding the refrigerant condensed in the condenser; an evaporator for cooling cold water with the refrigerant expanded in the expander and connected to a demanding place via cold water pipes; an ejector for partially passing the refrigerant compressed in the compressor and connected to the evaporator via an evaporator oil recovery path; an oil recovery path of the oil separator connected in such as manner that the oil leaked out of the oil separator passes through the oil recovery path so as to be recovered to the compressor; and an ejector outlet path connected in such a manner than the oil and the refrigerant leaked out of the ejector passes through the ejector outlet path so as to be recovered to the compressor. The oil recovery path of the oil separator and the ejector outlet path are disposed to be able to exchange heat. Therefore, it is possible to lower the temperature of the oil which has been recovered at high temperature via the oil recovery path of the oil separator is lowered. In addition, the liquid refrigerant which has been recovered via the evaporator oil recovery path is gasified in the evaporator. Therefore, it is possible to prevent the damage to the compressor and increase the efficiency of the compressor.

A horizontal type rotary compressor of a multistage compression system comprises a driving element and a compression mechanism section driven by the driving element in a horizontal type airtight container. The compression mechanism section is constituted of first and second rotary compression elements. A refrigerant compressed by the first rotary compression element is discharged into the airtight container, and the discharged refrigerant of intermediate pressure is further compressed by the second rotary compression element to be discharged. An oil separation mechanism is disposed to centrifugally separate oil from compressed refrigerant and passages are provided for cirulation of the oil.
