Techno-Economic and Environmental Assesment of Compressor Retrofitting Procedure
Keywords:Energy saving, carbon emission, greenhouse gas, variable speed compressor, retrofitting compressor.
In this study, retrofitting of a fixed speed refrigeration system to a variable speed refrigeration system isinvestigated. Economical and technical benefits of the retrofitting procedure are also studied. Refrigeration systems areusually designed to overcome maximum load conditions. However, they work under partial load in most of their life cycle.Hence, in this study a variable speed compressor that equalizes the cooling load to the demand that assures significantenergy saving is considered. As a result of this study, the retrofitted variable speed compressor performed 17%decreased energy consumption versus the thermostatic controlled fixed speed system. Also, the retrofitting procedureprovided considerable payback time. From the result, 10750 kilograms less carbon emission per year as anenvironmental benefit within retrofitting procedure is obtained.
