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.
