Performance of finned adsorber-desorber refrigeration system using activated carbon-methanol pair
Vivek Kumar Gaba
Adsorption refrigeration, being a unique and eco-friendly technology, has gained popularity over conventional refrigeration systems. The present study is aimed at developing an annular finned tube adsorber model which serves as a thermal compressor in adsorption refrigeration systems. The math-ematical model is addressed numerically using finite difference discretization method and explicit scheme was used for the solution. The generalized model has been simulated for activated carbon – methanol working pair. The system has an optimum cycle time of 1800s. It was found to have a highest refrigeration capacity of 260.665 kJ/kg at a regeneration temperature of 393 K and evaporator temperature of 283 K. The highest COP achieved by the system is 0.3706 at a regeneration temperature of 353 K and evaporator temperature of 283 K. A highest SCP of 144.8 W/kg was obtained at an evaporator temperature of 283 K and regeneration temperature of 393 K.
