Refrigerant R134a (tetrafluoroethane) is widely used
in automotive air conditioners and has a good performance. However, since
refrigerant R134a still has a high global warming potential (GWP), this
refrigerant must be replaced with environmentally friendly refrigerants such as
R600a (isobutane), which is a natural fluid, no effect on the climate,
inexpensive and readily available. In this study, thermodynamic analysis of a bus
air conditioner working with refrigerant R600a was performed. Adana province of
Turkey was chosen as the study region. Firstly, a bus used for inter-city
passenger transportation with a passenger capacity of 56 persons was selected.
Cooling Load Hourly Analysis Program (HAP) was used to determine the hourly
cooling load capacity of the selected inter-city bus model. Useful and
reversible works of compressor, coefficient of performance (COP), exergy
efficiency and exergy destructions of the bus air conditioning system were
obtained and evaluated in detail.
