الملخص EN
Adsorption cooling technology is one of the effective means to convert low grade thermal energy in to effective cooling, which improves energy efficiency and lowers environmental pollution.
'Ihe main objective of this study is to investigate the thermal performance of an adsorption refrigerator theoretically The working adsorbent/adsorbate pair used is Granular Activated Carbon, GAC/R134a pair.
The effect of different design parameters and operating conditions on the system performance is studied and interpreted.
Some assumptions and approximations are also considered.
A computer program is written using Matlab.
Results show that the equilibrium adsorption capacity is highly affected by the driving temperature and equilibrium pressure.
Increasing equilibrium pressure leads to a corresponding increase in the equilibrium adsorption capacity whereas it is value is decreased as the driving temperature increases.
Moreover, increasing the driving and evaporator temperatures raise the values of the Specific Cooling Effect (SCE) and Coefficient of Performance (COP).
The maximum values of SCE and COP are 60 KJ/kg and 0.4 cor responding to driving and evaporator temperatures of 100 “C and 20 °C respectively.
However, increasing the condenser temperature leads to a remarked decrease in SCE and COP of the cooling system.
SCE and COP values are 32 KJ/kg and 0.22 at driving and condenser temperatures of 100 °C and 40 “C respectively.
When comparing the present study results with literature, there is a good agreement in general.
It is clear that the adsorption cooling system can be driven effectively by low grade heat sources such as, solar energy, waste heat energy, geothermal energy...etc.
