… can be seen in the four next bullets. Waste heatGeothermal heatSolar heatHeat pump Other advantages obtained with lower temperature levels in heat distribution are. Lower distribution lossesHigher electrical power efficiency in CHPIncreased efficiency in flue gas …
… is therefore the additional cost of the cooling machine. The geothermal heat pump is designed to cover 60-70 percent of the maximum heat demand of the facility. The additional 30-40 percent will be covered by additional heating. A geothermal heat pump of 40 kW who require a 30 …
Beräkning av utnyttjningstid för en uppvärmd konstgräplan med alternativa rörplaceringar
… to heat the plan is a type of a geothermal heating system without a heat pump. The brine, which is water with 30% ethanol, collects heat from the borehole and discharges it to a coil in the field. There is at position 11 boreholes but it is planned to increase the number to 31 …
… case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios. Net …

… is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments …
… Efficiency concerning heat exchangers, their fouling resistance and also pumps. This thesis also relates to the industry in the big picture as heat exchangers and pumps are widely used and these has a great energy and environmental efficiency. This thesis presents an algorithm …
… att beskriva ungdomar med diabetes och deras erfarenhet av att använda insulinpump. Uppsatsen baseras på narrativa intervjuer med sex ungdomar tre flickor och tre pojkar i åldrarna 12-18 år (md=14,5). Kriterier för deltagande i studien var att ungdomarna skulle ha haft …
… ut och jämfördes. En Denilränna visade sig ha flest positiva egenskaper. Återpumpning av vatten för att bibehålla nivån trots flödet genom Denilrännorna skulle endast kräva en pump på 500 w och en energikostnad per år på mindre än 400 kr. Då Denilrännan är en billig och …
… be assumed that there are more built-in frequency converters without filter in pumps, compressors and machines in the whole net. After a number of measurements one can suppose that some parts of the FHP power net is unstable. In an unstable weak power net frequency converters …
