  1. 1. Normalization of Cooling Demand in Buildings, development, and evaluation of methods

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Xingtong Wu; [2022]
    Keywords : ;

    Abstract : Because of the increasing demand for indoor thermal comfort and the better insulation performance of building envelopes, cooling demand is an increasingly important part of building energy consumption despite the cold climate in Stockholm. Finding a way to normalize cooling demand to climatic conditions will help better energy audits to improve the building performance to achieve energy-saving. READ MORE

  3. 2. A Quantitative Microbial Risk Assessment Associated with Cross-Connections in the Drinking Water Network in Combination with Hydraulic Modeling

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fatin Alzuhairi; [2022]
    Keywords : EPANET; QMRA; Water distribution network; Health risk analysis; Cross-connections and backflow; Low pressure; Water quality; Simulation; Pathogen; EPANET; QMRA; vattendistributionsnät; hälsoriskanalys; korskoppling; lågtryck; vattenkvalitet; simulering; patogen;

    Abstract : Drinking water companies have the technology and responsibility to deliver safe and high-quality drinking water to the water distribution systems network (WDN). However, many events within the WDN, such as cross-connections and backflow, might degrade water quality and pose public health risks to consumers. READ MORE

  4. 3. Design and Development of an Experimental Test Rig for Heat Sinks

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Gabriel Kaduvinal Abraham; [2020]
    Keywords : Cooling; Experimental Setup; Flow rate; Heat sink; Plumbing; Sensors; Thermal Efficiency; Kylning; experimentell installation; flödeshastighet; kylfläns; VVS; sensorer; värmeeffektivitet;

    Abstract : Heat sinks are used mainly to take away the excessive heat which are produced in a component. This transfer of heat enables a smooth operation of the system with the heat generating component. The efficiency of heat sink is often dependent on the amount of heat it can take away within the smallest duration of time. READ MORE

  5. 4. Techno-economic analysis of demand flexibility from heat pumps for multi-family buildings in Sweden based on two case studies

    University essay from KTH/Energiteknik

    Author : Hsin-Ting Ko; [2020]
    Keywords : Demand flexibility; Heat pump; IDA ICE; Smart grid; Thermal comfort; Thermal inertia; Bottom-up simuleringsmodell; efterfrågeflexibilitet; Demand response; energiteknologi; slutanvändarbeteende; grön byggnad; VVS-systemkontroll; värmepump; IDA ICE; smart nät; termisk komfort; termisk tröghet;

    Abstract : Sweden is undergoing energy transition to become a zero-carbon economy with electricity production aims at 100% from renewable resources by 2040. Sweden also has a national goal to have fossil-free vehicle fleet by 2030. The increasing share of intermittent renewable resources creates growth in mismatches between electricity supply and demand.

  6. 5. Comparison of a hybrid ventilation system and a mechanical ventilation system with heat recovery through life cycle assessment : A case study of a modern Danish office building

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Josefine Nilsson Willkomm; [2020]
    Keywords : life cycle assessment; ventilation system; environmental impact; hybrid ventilation system; mechanical ventilation system with heat recovery; livscykelanalys; ventilationssystem; miljöpåverkan; ventilation; hybrid ventilationssystem; mekaniskt ventilationssystem med värmeåtervinning;

    Abstract : The building sector is responsible for 36% of the energy usage and 39 % of all CO2- emissions in European union (EU). Therefore, it is of great interest to investigate how the building sector can become more energy efficient and lower the environmental impact. READ MORE
