Optimizaton of fast hydrothermal liquefaction of biomass
(Master thesis, 2016)Fossil liquid oil possesses many properties that have made it one of our primary sources of energy on which modern societies are highly dependent on. With the growing concern of fossil fuels impact on the environment, there ... -
Optimize heat prosumers' economic performance under current heating price models by using water tank thermal energy storage
(Peer reviewed; Journal article, 2021)Due to heat prosumers' dual roles of heat producer and heat consumer, the future district heating (DH) systems will become more flexible and competitive. However, the current heating price models have not yet supported the ... -
Optimized and Cost Efficient Industrial Heat Pumps based on Low Grade Waste Heat
(Master thesis, 2016)The industrial sector is a large consumer of energy. Globally, this sector accounts for over half of the energy used. As anthropogenic emissions increase, and the consequences of these emissions become more evident, the ... -
Optimized industrial cooling of Atlantic salmon
(Master thesis, 2019)Når laks slakter er det nødvendig med rask og effektiv kjøling for å bevare kvaliteten og øke varigheten. Dette kan oppnås med en HeliX-tank, der laks kan både kjøles og renses for blod. Denne masteroppgaven har undersøkt ... -
Optimizing a Small Ammonia Heat Pump with Accumulator Tank for Space and Hot Tap Water Heating
(Master thesis, 2015)The heat pump market offers a wide variety of different residential heat pumps where most of them utilize refrigerant R-410A which has high global warming potential. Considering the fact that global policy ... -
Optimizing design and operation of chilling tank for Atlantic salmon
(Chapter, 2019)Farmed salmon is a large export product from Norway. After the salmon is stunned and killed, it is often transported to large tanks for bleeding, chilling and buffering before gutting and further processing. The temperature ... -
Optimizing Road Gradients Regarding Earthwork Cost, Fuel Cost, and Tank-to-Wheel Emissions
(Journal article, 2020)Emissions reduction has emerged as one of the principal targets in the planning and designing of road alignment today, and intelligent design methods can help optimize road alignment as a response toward more sustainable ... -
Optimizing the Compression/Absorption Heat Pump System at High Temperatures
(Master thesis, 2015)Large amounts of low grade waste heat from industrial processes are not utilized, due to lack of heat integration equipment. Industrial processes tend to have specifications at high temperature lifts, that not are suited ... -
Optimizing the heating and cooling system at Teknostallen
(Master thesis, 2023)For å redusere CO2 utslippet til atmosfæren har det vært forsøkt å implementere ulike energikilder for å møte energibehovet. Siden flertallet av fornybare energikilder kan produsere elektrisitet, har det blitt skapt en ... -
Optimizing the phosphorus resource use and emissions in a growing Norwegian aquaculture industry
(Master thesis, 2021)Fosfor (P) er en begrenset ressurs som også forårsake eutrofiering. Denne studien har ved bruk av en substansflytanalyse kvantifisert utslippene av fosfor (P), nitrogen (N) og karbon (C) fra norsk oppdrett av laks og ... -
