Nýtingarmöguleikar á borholum sem varmaskiptar fyrir seiðaeldisstöðina Tungufell
Markmið þessa lokaverkefnis var að kanna möguleika á að nýta borholur sem boraðar voru við jarðhitaleit í Breiðdal í kringum bæinn Tungufell sem varmaskipta. Þar er rekin seiðaeldisstöð fyrir laxa sem sleppt er í Breiðdalsá. Á svæðinu er nú þegar ein hola nýtt sem varma- skiptir með lokuðu …

Upphitun ferskvatns með jarðsjó í gashitara
Mikið er af heitum jarðsjó sem fellur til við rekstur jarðvarmavirkjana. Mikill varmi er í jarðsjónum sem hægt væri að nýta í að hita upp ferskvatn, en ef jarðsjór fer beint í varmaskipti verða miklar kísilútfellingar sem geta valdið neikvæðum áhrifum á varmaskiptinn og afköst hans. Markmið …

Feasibility of supercritical CO2 coaxial heat exchanger geothermal well conversion with ECO2G technology
The feasibility of converting non-producing geothermal wells to closed loop supercritical CO2 coaxial heat exchanger using ECO2G technology was analyzed for two heat exchanger scenarios. The first scenario, Case A, utilizes the existing production casing as the heat exchanger and plugs the well at …

Evaluation of energy demand and energy use of an existing single family building, with special emphasis on energy efficiency of heat exchanger in ventilation
Energy modelling of houses and other buildings helps the designers to determine the energy performance of the building at an early stage. It furthermore gives the advantage of altering the building’s design early in the planning phase to ensure that it fulfils requirements of increasing energy …

Furnace offgas waste heat utilization
The project investigates a heat exchanger design concept for a furnace offgas pipe from an industrial furnace at Elkem. The goal is to develop a heat exchanging concept for harvesting exhaust heat using a numerical model. The proposed heat exchanger duct goes around a 3,2 m diameter pipe, and its …
