Thermodynamic Analysis of an Intercity Bus Air-Conditioning System Working with HCFC, HFC, CFC and HC Refrigerants

The purpose of this study is to perform thermodynamic analysis of an intercitybus air-conditioning (ICBAC) system working with hydrochlorofluorocarbon(HCFC), hydrofluorocarbon (HFC), chlorofluorocarbon (CFC) andhydrocarbon (HC) refrigerants. For this aim, an intercity bus with a busload of56 passengers, which is thought to motion in the Adana province of Turkey,was selected. R404A, R410A, R502, R507, R22, R290, R134a, R500 andR600a were selected as different HCFC/HFC/CFC/HC refrigerant types in theICBAC system. Useful and reversible works of compressor, coefficient ofperformance (COP), exergy efficiency and exergy destructions of the entireICBAC system and its each sub-unit were obtained. The results showed thatthe performance of the ICBAC system was significantly influenced bychanging the refrigerants. However, R600a refrigerant based on hydrocarbonwas found as a refrigerant to have minimum total exergy destruction,maximum exergy efficiency and maximum COP compared to otherrefrigerants used in the ICBAC system with the same amount of cooling loadand the same climatic condition.
