1. 1. Energy analysis between traditional hot water circulation system and an innovative pipe-in-pipe system

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Alejandro Abellán Guallarte; [2022]
   Nyckelord :Hot water circulation; pipe-in-pipe; energy saving; buildings; heat losses; warm water;

   Sammanfattning : We are at a time when energy efficiency and the reduction in the use of non-renewable energy is an important objective in all aspects and will continue to be so, therefore it is necessary to try to reduce energy and heat losses in the systems used in homes and, in particular, in the domestic hot water (DHW) system. This study aims to find out the advantages and disadvantages of an innovative pipe-in-pipe (PIP) system for DHW circulation with respect to the conventional system of two separate pipes. LÄS MER

3. 2. Investigating the possibility of Jakobsgårdarna district in Borlänge, Sweden becoming a Positive Energy District (PED)

   Magister-uppsats,

   Författare :Rayan El Sawalhi; [2022]
   Nyckelord :Positive Energy District PED ; Building energy Modeling; IDA ICE; urban scale; district heating; heat pumps; photovoltaic panels; energy demands; energy production;

   Sammanfattning : Climate change is a global phenomenon that strongly affect cities and urban areas. Due to the intensive industrial activities and global population growth leading to more fossil energy demands for the last century, the global warming effect appeared to have been significantly exacerbated.

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

   Master-uppsats, Högskolan Dalarna/Energiteknik

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

   Sammanfattning : 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. LÄS MER
