Active latent heat storage using biowax in a central heating system of a ZEB living lab
Sevault, Alexis; Næss, Erling (Chapter, 2020)The Zero Emission Building (ZEB) lab in Trondheim (Norway), owned by SINTEF and NTNU, provides a structure to develop and test innovative solutions in a living laboratory. An innovative latent heat storage (LHS) unit using ... -
CFD modeling of ice formation and melting in horizontally cooled and heated plates
Selvnes, Håkon; Allouche, Yosr; Sevault, Alexis; Hafner, Armin (Chapter, 2019)This paper investigates the ice formation and melting processes in a novel CTES unit using the commercial CFD software ANSYS Fluent 19. The storage unit is designed to operate as a peak shaving device integrated into the ... -
Cold thermal energy storage with low-temperature plate freezing of fish on offshore vessels
Verpe, Espen Halvorsen; Tolstorebrov, Ignat; Sevault, Alexis; Hafner, Armin; Ladam, Yves (Chapter, 2019)This paper presents the results of a numerical and experimental study of freezing time for fish in plate freezers, and the potential for improvement by altering fish block thickness and lowering evaporation temperature. ... -
Design av en PCM-basert varmelagrinsenhet for ZEB Flexible Laboratory
Bøhmer, Fabian (Master thesis, 2019) -
Experimental design and testing of a PCM-based heat storage unit for wood stoves
Mathisen, Henning Hvål (Master thesis, 2019)Bruken av vedovner har lange tradisjoner i Norge, både når det gjelder oppvarming og hygge. Moderne hus er gjerne godt isolerte med lite varmetap og siden vedovner typisk har høy varmeavgivelse, kan dette føre til overoppheting ... -
Investigation of an Innovative Latent Heat Storage Concept in a Stovepipe
Sevault, Alexis; Soibam, Jerol; Haugen, Nils Erland L; Skreiberg, Øyvind (Journal article; Peer reviewed, 2018)Latent heat storage (LHS) is a promising concept for small-scale batch combustion. One example is wood stoves, which rely on a batch combustion process that yields a transient heat production with high peak effect. A ... -
