… (district heat) and ”free” energy (heat from humans, electric apparatus, solar energy and lights). The losses include unwanted ventilation, transmission, ventilation, and tap water losses. Calculations have been done with help of collected statistics, measurements and …
en studie av kommunala taxor och avgifter
… The result is ambiguous. For charges on environmental goods such as solar collectors and heat pumps, a counteraction exists between subsidies and local charges but the level of the problem varies substantially. The charge for a heat pump may differ from 0,3 percent to almost 20 …
… walls and upgrading the ventilation systems to recover heat. Alternatives for solar electricity and heat generation have also been presented. Results show that both solar heat and electricity can be economically viable. The viability of the solar electricity alternatives are …
… Agricultural Research Trust premises in Batoka, Zambia, with 40 broilers and solar lamps (HiLights from HiNation). The broiler chickens were divided into two groups, both had free access to feed and water and the experimental group received two and a half hours of extra light …
a Cost Benefit Analysis of the socio-economic effects from implementing new clean drinking water technologies in rural India
… an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in …
… of the sun onto a receiver. The receiveris equipped with mono crystalline solar cells and is cooled by a circulating liquid media. The electricity is supplied to the local grid and the heat is supplied to a local heating system. In this master thesis, the author has developed a …
… through the buildingenvelope and to take advantage of the passive heat from solar radiation,installation and heat sources like people living in the house.This project has been made with help of Anebyhus and one of their model houseshave been examined from the report’s issues …
Hållbara uppvärmningsalternativ för vandrarhemmet på Finnhamn
… energy. The alternative system that this project focuses on is a system of solar collectors combined with a wood chip boiler. Information for the project is collected from a literature review. Also persons with good knowledge of renewable energy systems, or Finnhamn and the …
… and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground. The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of …
Även i symbios med solfångare
Rapporten handlar om ett examensarbete omfattande 20 p som är utfört för Thermia AB i Arvika. Uppdragsgivaren ville få fram förslag på möjliga åtgärder som kan minska ljudnivån från en luftvärmeväxlare. För bra helhetsbild av projektet, läs även kapitel: 6. Värmeväxlaren ingår …
… heat and electricity to the house I decided to use a wind turbine and a solar water heater. The most difficult part of designing a house that is energy independent is that the produced energy must be stored somehow. Storing the heat is relatively easy beacuse the heat can be …
… the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be …
Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the …
Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher …
… out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the …
