  1. 1. The Energy Savings Potential of a Heat Recovery Unit and Demand Controlled Ventilation in an Office Building

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Fagernäs Martin; [2021]
    Keywords : Demand Controlled Ventilation; DCV; Heat Recovery Unit;

    Abstract : The building sector is responsible for approximately 40 % of the total energy usage in Sweden. In office buildings the heating, ventilation and air conditioning system can account for up to 55 % of the energy usage. In order to reduce the energy usage of the heating, ventilation and air conditioning system different control methods are often used. READ MORE

  2. 2. Machine Learning Implementation for Curing Carbon Fibers using Microwave Technology

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Srivijay Manjunath; [2021]
    Keywords : ;

    Abstract : Curing of carbon fibers using microwave technologies was shown to improve ove rprocesses based on thermal heating, both by reducing time and energy cost. However, realization of the full potential of the approach is hampered by the non-even distribution of the energy during curing. READ MORE

    Keywords : Carbonate Materials; Porous Materials; Carbon Dioxid Sorption; Point Sources; Amorphous Calcium Carbonate; Mesoporouse Magnesium Carbonate; Calcium Magnesium Carbonate Composite;

    Abstract : During the past decades, emission of greenhouse gases has accelerated to unsustainable levels. This is a serious issue that can have a devastating impact on everything from global economy to the terrestrial or marine ecosystem. A method for reducing the emission is named carbon capture and storage, which this project is based on. READ MORE

  5. 5. Simulation Validation with Real Measurements of an Intelligent Home Energy Management System.

    University essay from Högskolan Dalarna/Energiteknik

    Author : James Jose Panangat; [2021]
    Keywords : Intelligent home energy management iHEM ; TRNSYS validation; Solar thermal validation; Space heating SH validation. Domestic hot water DHW validation.;

    Abstract : This thesis's main objective is to conduct a comparison study between measured values and simulated results of a demonstrator, of the intelligent home energy management (iHEM) project. The comparison helps to validate the simulation. TRNSYS software is used for the design. In this study, only the thermal energy side of the project is considered. READ MORE
