| Summary: | Detail experiments and analyses have been made on the solar refrigerator
using activated charcoal and methanol adsorption cycle. A test rig was designed to
study adsorption and desorption capability of activated carbon. A comparison has
been made between adsorbability of six Malaysian commercial activated carbons. To
improve the adsorbability of the carbon a simple method was tested.
Base on Dubinin equation, some them10dynamic properties of adsorbent
adsorbate necessary for refrigeration calculation had been obtained. In this
experiment methanol is used as the refrigerant medium. The amollnt of methanol
adsorbed by the activated carbon was measured as a function of temperature of the
activated carbon. During the experiment, the temperature of the unadsorbed
methanol was kept constant. From Dubinin-Astakhov equation, parameters of
adsorption data were determined using graphical analysis. A Claperyon P-T-X
(pressure, temperature and concentration) diagram was then constructed. |
