Abstract

CFC (ChloroFluoroCarbon) and HCFC (HydroFluoroCarbon) refrigerants, which are used for vapour compression refrigeration cycles cause serious environment problems. So research is going on solar refrigeration (producing cooling effect using solar energy is a promising way to achieve sustainable development, since the energy used is free and not harmful for the environment) and also used for environment friendly refrigerants. In this paper, heat and mass transfer analysis of adsorption refrigeration system is done in which solar energy as well as environment friendly refrigerant is used. The proposed adsorption refrigeration system is based on silica-gel–water adsorption pair. The heat source is waste heat from diesel engine and solar energy simultaneously. The performance of the proposed cycle is evaluated with the help of the mathematical model at equilibrium condition, is compared with the performance of the basic two-bed adsorption refrigeration cycle. This makes the system a continuous process. It is seen that the cooling effect as well as COP of the proposed cycle is superior to the basic cycle. The system is developed for cold storage in rural area where availability of electricity is very less.
