… in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties. To find possible answers to the higher electricity use a …
… the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the …
… into how the silicon content of an aluminium alloy affects the coefficient of thermal expansion (CTE). The goal of this paper is to better understand and to find a relation between silicon content and the coefficient of thermal expansion. Experiments were carried out using …
… for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells. The work has therefore been focused on verifying …
… effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor …
… in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction of solar energy has been …
Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle …
… thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume. Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first …
Undersökning av temperatur- och luftbeteende intill höga glasfasader och i vistelsezon med golvvärme som en värmekälla
… in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest …
… thesis has been carried out at the Production Tech-nology Centre where the Thermal Spray research group of University West has its work-shop and labs. This research work has been performed in collaboration with the International Advanced Research Centre for Powder Metallurgy and …
… from the production hall leads to high cooling demand to maintain good thermal comfort. Limitations in operation control of the buildings HVAC (Heating, Cooling and Air-conditioning) systems causes high heating and cooling demand and hence the buildings thermal mass is not …
… batteries during charging are examined and the preliminary results indicate a thermal loss of approximately 10% of the energy the battery is charged with. The thermal loss in percent is the same at room temperature as at -10°C and -20°C.
… In addition, tests have been performed to determined the coefficient of thermal expansion for the different compounds. This analysis was made from powders to avoid the interference of stresses. These coefficients have been used to determine the thermal contriribution to the …
… means that there isn’t any cooking involved. The staff receives the food in thermal bags or thermal cabinets from a kitchen that makes the meals. This system involved more transportation, witch means that the food has to be warm for a longer time. The purpose of this project is …
Thermally-insulated balconies
… exists on the market. In the work there is also a short description of thermal bridges concerning balconies. A description of older solutions for balcony connections is given as well as a calculation of the difference in energy costs for a insulated balcony connection compared …
