Abstract
- In adsorption refrigeration, one of the key factors is the choice of the working pair. Therefore, the adsorption and desorption equilibrium data are very useful for designers and also for the analysis of the thermodynamic performance. In this paper, R-123 (2,2-dichloro- 1,1,1 -trifluoroethane) refrigerant with activated carbon adsorption cooling working pair is investigated. The adsorption is carried out with a thermogravimetric balance, and the equilibrium data are obtained. The Dubinin-Astakhov modified model is used to calculate the adsorption equilibrium parameters. The maximum adsorption capacity is obtained. The standard estimate error (SEE) between the experiment and the model result is evaluated. The results give a good agreement with the experiment data. The influence of the heterogeneity coefficient n to the adsorption capacity is presented. Desorption also is carried out to calculate the thermodynamic performance (refrigeration capacity) at different regeneration temperatures.
