Accurate adsorption isotherms of R134a onto activated carbons for cooling and freezing applications.

Author(s) : SAHA B. B., SHARKAWY I. I. el-, THORPE R., et al.

Type of article: Article, IJR article

Summary

The objective of this article is to improve the performance of thermally powered adsorption/cooling systems by selecting a new adsorbent/refrigerant pair. Adsorption equilibrium data of R134a onto granular activated carbon (AC) and Unitika activated carbon fiber (ACF) of type (A-20) have been measured experimentally using Rubotherm ISOSORP 2000 within evaporation temperatures range between -20 and 40°C and adsorption temperatures range from 30 to 80°C. Experimental data have been correlated using various popular isotherm models. The isosteric heat of adsorption of the assorted adsorbent/refrigerant pairs has also been extracted from the present experimental data.
