Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent …
Simulering av lagerutformning och konsekvensen av adderade uppvärmningsbehov motsvarande en pool och ett atrium
… supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest. Today's existing plants are mainly in Europe and particularly in Germany. These facilities are …
… to investigate and describe the circumstances for the spare parts stored in storage facilities within the area of operation. Even new facilities which could serve as storage rooms and their opportunities for storing spare parts were an important part of the investigation. This …
… is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol …
Storage of biomass is often associated with problems such as heat development, dry matter losses and reduction of fuel quality. The rise in temperature can potentially cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles can cause health …
inverkan av lagringstemperatur, lagringstid och vattentillgång
This thesis is a part of the project "Sustainable harvesting and storage of sugar beets, more sugar to practice". The work has included a large part of practical experimental work with weight measurement, graduation and storage planning. The aim of the project is to be able to …

… the main reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a …

… sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic …

Kombinerar användning och förvaring av bits
… and handheld screwdrivers in a greater spread. For these different types of storage, from pure storage boxes to complex tools with storage built in, exist. The professional craftsmen commonly use some kind of box where the bits can be stored. Even so they tend to store their …
effect of pH, carrageenan and storage time
… of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product’s …
… heat, something which could be achieved through integration of a seasonal heat storage in the energy system. The purpose of the Master’s thesis is therefore to explore the economic and technical potential for a seasonal heat storage in Tekniska verken’s energy system. The …
… in the aquifer and to some extent in the groundwater. Application of aquifer storage for the use of geothermal energy is mainly used in large scale facilities and is limited to sites with suitable aquifers in the form of ridges, sandstone and limestone aquifers. Löwenströmska …
… had on the mineralisation of the substrate as well as the stability during storage of the product. Laboratory experiments were performed, with seven trails where the temperature was set to 37°C, 55°C or 70°C. The rate of drying was varied by letting water either evaporate, or …
