Energy, Exergy, Environmental and Economic Analysis of Heavy Duty Vapor Compression Chiller with Alternative Fluids in District Cooling

A district cooling system (DCS) is superior to conventional air conditioning as it helps to reduce energy consumption and protect the environment by reducing carbon dioxide emissions. The investigation of the actual/existing vapour compression refrigeration (VCR) system used in the DCS has not been...
