Adsorbent bed with new structure based on solar adsorption refrigerator

In this study, a new solar solid adsorption ice maker with honeycomb adsorbent bed and activated carbon-methanol pair was developed and examined. Experimental results showed that the directly solar-irradiated adsorbent bed could effectively increase the bed temperature, and a maximum bed temperature of 117℃ was measured. Results also indicated that the temperature difference between the front and back surface of the bed was less than 5℃, and this result showed that the adsorbent bed was excellent in the heat transfer. Experimental results also indicated that the COP of the system was related to climatic conditions as observed by other researchers, and maximum COP of 0.157 was found during the period of experiments.
