Absorption refrigeration systems are compression refrigeration systems that use thermal compressors. Such systems have the advantages of reduced electricity consumption, lower maintenance costs, and the elimination of CFC and HCFC use as refrigerants. They also allow cogeneration and solar energy as an inp...
Unlike the turbine operation, which expands the working fluids in the direction of flow, the compressor works to decrease the air volume in the direction of the flow. Thus, discrete low pressure ratio compression stages, particularly for axial compressors, are helpful in minimizing the tendency to...
