Abstract

A multistage refrigeration system having a first stage system that circulates a first refrigerant through a first compressor, a first condenser, and a first evaporator. The system also has a second stage system that circulates a second refrigerant through a second compressor, a second condenser, and a second evaporator. The first refrigerant in the first evaporator exchanges heat with the second refrigerant in the second condenser. The first stage system circulates a first lubricant and the second stage system circulats a second lubricant. The first lubricant exchanges heat with the second lubricant and the first lubricant provides lubrication to the first compressor and the second lubricant provides lubricant to the second compressor.
