Abstract
The first experience in the operation of intensified heat transfer adsorption bed reactor designed for low-pressure adsorption processes is presented in this paper. This work aims to assess the possibility of fluidizing the porous media bed induced by the pressure difference between the evaporator and the adsorption reactor. The conducted experimental research allowed indicating the type of silica gel recommended to use in fluidized beds of adsorption chiller. The fixed bed of silica gel was observed for the lower pressure differences, while fluidization appeared in the case of the pressure difference between the evaporator and the adsorption chamber higher than 1000 Pa. The most significant differences in the adsorption process between the fixed bed and the fluidized bed are revealed in the changes of sorbent temperatures. The silica gel bed was fluidized with water vapor generated in the evaporator.
Highlights
The first one presented the fixed adsorption bed and is called a fixed state and the second case corresponds to the fluidized bed and is called a fluidized state
The experimental results from the first experience of the intensified heat transfer adsorption bed (IHTAB) facility were presented in this paper
The fixed or fluidized state in the bed of adsorption material was induced by changes in pressure differences between the adsorption chamber and the evaporator
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. The optimal conditions of the proecological endeavors have been discussed internationally for several decades [1]. According to the concluded global climate regulations, economic growth in the 21st century has to comply with the sustainable development concept [2]. The increasing electricity demand led to excessive exploitation of natural resources, justified by higher production efficiency. In the face of global warming, many actions are taken to improve the industry’s energy efficiency. One of the critical tasks in this area is the diversification of energy sources. Low-carbon technologies are currently being implemented in many industries, including heating and cooling technologies [3,4]
