“…Chile, on the other hand, is facing increasing energy demands in order to respond to the expected social, environmental and economic welfare of the population. Its primary energy mix depends on oil (32.9%), coal (24.4%), wood and biomass (23.7%) and hydroelectricity (6.4%) [77]. The industrial and mining sectors consume 64% of total electricity consumption [78].…”

“…An extensive review of PCMs in terms of material properties, encapsulation and heat transfer enhancement was carried out by Li et al [32,33]. There is a number of studies focusing on ice [34][35][36] and the outcomes are positive, meaning that the inclusion of ice brings energy savings [37,38]. However, PCMs with higher melting temperatures are more suitable to work with standard air-conditioning systems because they are able to work with heat transfer fluid (HTF) temperatures above 0 • C. Thus, according to [39], PCMs with a melting/solidification temperature around 8 • C are suitable materials for these applications.…”

Phase-Change Materials in Hydronic Heating and Cooling Systems: A Literature Review

et al. 2020

When considering the deployment of renewable energy sources in systems, the challenge of their utilization comes from their time instability when a mismatch between production and demand occurs. With the integration of thermal storages into systems that utilize renewable energy sources, such mismatch can be evened out. The use of phase-change materials (PCMs) as thermal storage has a theoretical advantage over the sensible one because of their high latent heat that is released or accumulated during the phase-change process. Therefore, the present paper is a review of latent thermal storages in hydronic systems for heating, cooling and domestic hot water in buildings. The work aims to offer an overview on applications of latent thermal storages coupled with heat pumps and solar collectors. The review shows that phase-change materials improve the release of heat from thermal storage and can supply heat or cold at a desired temperature level for longer time periods. The PCM review ends with the results from one of the Horizon2020 research projects, where indirect electrical storage in the form of thermal storage is considered. The review is a technological outline of the current state-of-the-art technology that could serve as a knowledge base for the practical implementation of latent thermal storages. The paper ends with an overview of energy storage maturity and the objectives from different roadmaps of European bodies.
