Varvtalsstyrning till utvalda pumpenheter på Blekeri 4
… efficient as possible to reduce the amount of energy used. About 10 TWh of electricity used annually to pump drives in Swedish industry. Therefore, pumping system has great potential for energy savings. The objective of this report was to determine how much energy and money that …
Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for …
Simuleringsstudie kring energiförsörjning av vitvaror med hjälp av värmepump & ackumulatortank
… option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source. This is where the heat pump shines being an excellent way of removing excess heat where it is not needed to somewhere where it is put to good use. The goal of this …
… The building itself has an inadequate building shell and direct acting electric radiators are currently installed as heating system. These factors lead to high energy costs. Our mission is to analyze which measurements can be taken to increase the hostels energy efficiency. A …
- Ett initiativ till utveckling av bränsleceller i Sverige
… continue to use fossil fuels at the rate we do. When it comes to generating electricity we are constantly trying to come up with cleaner and more efficient solutions. The fuel celltechnology is one such alternative and has been around for over 100 years. Yet, it is not until now …
En fallstudie av ett flerbostadshus, Kv. Fyrtornet
… reviews has been initiated in order to be able for showing how the house electricity could be carried out even more efficiently. The work was initiated through a literature study to clearly increase the reliability on the energy subject. Different concepts of low-energy …
… and converting the thermal energy of a combustion engine to mechanical/electric power the efficiency of the combustion engine can be increased. In this work the performance of a truck engine has been investigated with the aim to increase its efficiency by decreasing the heat …
… used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy …
… discussed.According to the modelling it takes 90 to 105 seconds to reduce the electrical outputfrom a power plant with CCS with one percentage point, depending on whichload the change is made from. A coal fired power plant without the CCS technologyis approximately eight times …
En beskrivande litteraturstudie
… in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower …
Studie om arbetsrelaterad stress och faktorer som påverkar psykosocial arbetsmiljö inom human service organisationer i offentlig sektor
