Abstract
An adsorption refrigeration system (ARS) working on silica-gel/methanol pair has been investigated analytically and experimentally. By applying the mass balance in the adsorber bed the mechanism of adsorption in the thermal compressor with respect to time and bed length was determined. An experimental analysis was performed using a thermal gravimetric analyzer (TGA) to evaluate the mass transfer coefficient and optimum cycle time for silica-gel/ methanol pair at different working temperatures. The Diffusion coefficient Ds and Activation energy Ea for silica-gel/methanol pair were found 2.55 × 10–4 m2/s and 83.08 KJ/mol. Further, the results of variation of regeneration temperature on the performance of the system in terms of COP (Coefficient of Performance) and SCP (Specific Cooling Power) was evaluated; the maximum average theoretical COP and SCP achieved by the system was 0.5 and 102 W/kg near about 127°C regeneration temperature.
Highlights
The adsorption refrigeration technology uses a low grade of energy (Heat) instead of a high grade of energy (Work) for refrigeration purposes
Figure (4) shows the variation in adsorption with bed length (z), the adsorption (n) is higher at the entering side of methanol and lowers at the end of the adsorber bed which is due to the layer by layer phenomenon of adsorption
A continuous vapour adsorption refrigeration system (ARS) with two adsorber beds powered by the exhaust gases of the I.C. engine has been described
Summary
The adsorption refrigeration technology uses a low grade of energy (Heat) instead of a high grade of energy (Work) for refrigeration purposes. Debris resulting from the corrosion fouls narrow down the openings in the system.
