This paper aims at the study of heat transfer coefficient, effectiveness and capacity of trans critical CO2 for plain fin and tube gas cooler to investigate the effect of fin density, fin thickness, transverse and longitudinal tube spacing, gas cooler width and air inlet temperature. For this purpose, the Indian climate conditioned condenser model was used which have 40 °C DBT and the condenser pressure 90 bar. The thermo-physical and transport properties of CO2 have a monitor for the physical behavior at state point of the fluid or mixture using REFPROP software. Refrigerant and air side heat transfer coefficients were estimated and compared with the available correlations. It has been observed that the heat transfer coefficient and effectiveness for 830–1030 m3/h flow rate shows intimacy with rich correlation compared with other correlations.
