A review on adsorption cooling systems with adsorbent carbon

Abstract. Economic reasons and quest for new solutions based on recovering the energy have provoked an increase of interest in the adsorption technology in the refrigeration industry. The confirmation can be the fact that number of published research is on rise. Adsorption appliances may turn out to be an alternative to compression-type coolers. They use ecological chemical agents instead of substances which are aggressive and harmful to the environment. For regeneration of adsorptive refrigeration systems one can use cheap energy in a form of: industrial waste heat, energy of solar radiation and cheap electric power. The paper presents principles of operation as well as advantages and disadvantages of adsorptive refrigeration systems. Basing on literature the most frequently used adsorbentadsorbate systems -which are employed in refrigeration industry -have been characterized. A review of construction solutions of systems on both laboratory and industrial scale has been made.

“…Activated carbon with methanol as a working pair is broadly used in adsorption refrigeration due to the large adsorption quantity and low desorption heat, which is about 1800-2000 kJ kg À1 [4]. The adsorbent (solid porous material) properties indicate that the activated carbon is a good choice for adsorption cooling because of its high capacity for desorption and adsorption reaches 0.45 kg kg À1 [6].…”

Adsorption Capacities of Ammonia‐Activated Carbon Pairs in a Single‐Bed Adsorption Cooling System

In this study, the adsorption capacities of activated charcoal‐ammonia working pairs at room temperature, at which waste heat is supplied, were studied in a tube‐in‐tube adsorption bed in the pressure range of 0.4–10 bar. A double‐pipe adsorption bed was designed, constructed, and utilized for sequential adsorption and desorption of ammonia at 27 °C. Three types of granular activated carbons (GACs) with different particle size distributions were used as adsorbents. Experimental observations showed that the highest adsorption capacity for ammonia was shown by GAC‐2 with broader particle size distribution. The adsorption behaviors of all three adsorbents closely followed the Langmuir model under the operating conditions used in the study.
