Experimental Study on Heat Transfer of Finned Concentric Tube Adsorbers During Desorption Processes
摘要
Abstract
In order to enhance heat transfer in finned concentric tube adsorbers during desorption processes, the heat transfer performance of finned concentric tube adsorbers with different heights of 30 cm, 40 cm and 50 cm were studied with water-bath heating. The results show that the desorption heat of the adsorbate increases with the increase of adsorbent temperature. Under same adsorbent temperature, lower condensing temperature results in higher desorption heat of the adsorbate. The sensible heats of adsorbent and adsorbate increase with the increase of adsorbent temperature in the concentric tube. Moreover, the sensible heat of the adsorbent is much larger than that of the adsorbate under same temperature. The temperature of the mass transfer channel in the finned concentric tube is close to the temperature in the middle of the adsorbent, with temperature difference of 0.1~1.5. Compared with the 30 and 50 cm finned concentric tube adsorbers, the temperature variation ℃coefficient in the mass transfer channel of the 40 cm finned concentric tube adsorber is relatively more stable.关键词
