Analiza procesa adsorpcije glede na dolžino nasutja adsorbenta

Jocić, Anastasija (author), Stritih, Uroš (mentor)

V diplomskem delu obravnavamo področje termokemičnega shranjevanja toplote, in sicer adsorpcijsko shranjevanje. V zadnjih letih je bilo za termokemično shranjevanje energije veliko zanimanja in povpraševanja. Trenutne raziskave se v večini osredotočajo na adsorpcijsko shranjevanje, tj. testiranje novih adsorpcijskih materialov in konfiguracijskih sistemov. Napredek le-teh kaže, da bi bilo adsorpcijsko shranjevanje toplote dokaj realistična in trajnostna možnost za sezonsko shranjevanje toplote. V drugem sklopu naloge je prikazana zasnova eksperimentalne proge, kjer je bilo izvedenih 48 meritev za različne dolžine nasutja adsorbenta. Material, ki smo ga preizkušali, je bil Zeolit 13X, dolžine nasutja pa so bile v razponu od 3 do 10 cm. Na podlagi meritev smo potem izvedli energijske in masne bilance s pomočjo parametrov, ki so bili izmerjeni na eksperimentalni progi. Iz dobljenih rezultatov smo opazili, da sta akumulirana toplota in gostota shranjevanja pri daljših nasutjih precej manjši.

Abstract

The thesis deals with the field of thermochemical heat storage, namely adsorption storage. In recent years, thermochemical energy storage has gained a lot of interest. Most of the current research focuses on adsorption heat storage; testing of new adsorption materials and system configurations. The progress of these alone shows that adsorption heat storage would be a fairly realistic and sustainable option for seasonal heat storage. In the second section, the design of the experimental setup is presented, where 48 measurements were conducted for various lengths of adsorbent bed. The material tested was Zeolite 13X, with bed lengths ranging from 3 cm to 10 cm. Based on the measurements, we conducted energy and mass balances using parameters obtained from the experimental setup. From the obtained results, we noticed that the accumulated heat and storage density were significantly lower for longer bed lengths.
