Zeolites in Heat Recovery

Adsorption heat pumps (or refrigerators) and heat transformers are possible application modes for heat recovery purposes. The primary energy efficiency is higher for them; they have many other advantages over the conventional heat pump systems, if proper adsorbent-adsorbate pairs are used they become a very effective device for utilization of waste heat, solar energy, geothermal energy and peak electricity. Theoretical and experimental work for different zeolite-water pairs, active carbon-methanol pair, silicagel-water pair were performed. The variation of energy requirements, heating and cooling loads with the available energy source temperature are given. Comparison of the theoretical and experimental results were done for local clinoptiolite. © 1989, Elsevier Science & Technology. All rights reserved.
