Abstract This paper discusses the mathematical formulation for various heats involved during different processes of a simple vapour adsorption refrigeration cycle having activated carbon and methanol as the active working pairs. This formulation is further used and a detailed analysis of the cycle’s performance is studied based on a steady-state model prepared on the FORTRAN77 platform compiler. The analysis includes effects of the input parameters of the cycle such as temperature at the end of desorption (T3), the minimum temperature in the cycle or temperature at the end of adsorption (T1), condenser and evaporator temperatures (TC, TE) over a suitable range, on the performance parameters of the cycle such as desorbed mass ratio (ΔX), heats of adsorption and desorption, refrigeration effect, total heat supplied for desorption, and the coefficient of performance (COP).
