Study of Micro-porous Characteristics of Activated Carbon

Refrigeration technique on account of its multidimensional approach is obligatory to meet the need for daily life. This mechanism virtually encompasses the transfer of heat from the low temperature region (source) to the high temperature region (sink) by means of a working fluid called refrigerant. Conventional refrigeration, air conditioning and heat pump systems have been employing halogenated refrigerants such as CFCs, HCFCs and HFCs over many decades due to their excellent thermodynamic and thermo-physical properties. But these refrigerants have potent negative impact on the environment. In view of this alarming problem, the exploration of alternative and promising refrigerant having zero ODP and GWP with a suitable refrigeration system for the replacement of halogenated refrigerants is the need of the hour. In this regard, adsorption refrigeration system could be a unique solution. Because, it is well established that activated carbon developed from matured coconut shell has an excellent gas adsorption properties and the process is exothermic, which becomes endothermic during desorption of gases.
