80 K Centrifugal Compressor for Helium Refrigeration System

80 K Centrifugal Compressor for Helium Refrigeration System

A centrifugal compressor for a completely lubricant free helium refrigeration system is now being developed using magnetic bearings. The compressor has four compression stages and each stage is independently driven by a 25-kW built-in motor at the speed of 100, 000 rpm. The inlet of the compressor is maintained at a temperature of 80 K during ...

Low-pressure chillers are typically centrifugal chiller type refrigeration systems operating under a vacuum in the evaporator section of the system. The condenser and compressor sections could be at a slightly negative pressure or up to 15 psig of positive pressure. High head pressure is a sign that there is air in the system’s refrigerant.
