  1. 11. Optimizing Energy System in a Supermarket : A case study analysis

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Filip Josefsson; [2022]
    Nyckelord :R744; heat recovery; refrigeration system; supermarket; optimization; water-cooled condenser gas cooler; R744; värmeåtervinning; kylsystem; livsmedelsbutik; optimering; vattenkyld kondensor gaskylare;

    Sammanfattning : With more restrictions regarding the use of refrigerants with high GWP-values, refrigeration systems that uses R744 (Carbon dioxide) as a refrigerant increases. Supermarkets are energy intense facilities where the refrigeration system utilize a significant part of the total utilized energy. LÄS MER

  3. 12. Utvärdering av en ny torkningsteknik för diskmaskiner : En parameterstudie som utvärderar torkprocessen i en diskmaskin integrerat med värmepumpsteknologin

    Master-uppsats, Karlstads universitet

    Författare :Adam Ståhlberg; [2022]
    Nyckelord :Energibehov; Torkningsgrad; Torktumlare; Fuktig luft;

    Sammanfattning : Denna studie har undersökt en torkningsprocess för diskmaskiner där värmepumpsteknologin appliceras. I och med den nya energimärkningen som implementerades för vitvaror under 2021, har detta inneburit hårdare krav på energianvändningen för diskmaskinsindustrin. Torktumlare har tidigare genomgått samma problematik som diskmaskinerna. LÄS MER

  4. 13. Development of a Simulation Model for Combined PVT and Ground Source Heat Pump Systems : A TRNSYS Model Created for Commercial Use

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :HANNA OLAUSSON; EMMA WERNIUS; [2021]
    Nyckelord :Electrify everything; Solar assisted heat pump; Solar Energy; TRNSYS; Elektrifiera allt; solassisterad värmepump; Solenergi; TRNSYS;

    Sammanfattning : The Swedish government has set a target of a 100% renewable electricity system by 2040. To reach this goal, many actions have to be undertaken. Electrification of buildings is one action to be undertaken as the residential sector accounts for a large share of greenhouse gas emissions, where the most energy efficient method is to use heat pumps.

  5. 14. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hjörtur Brynjarsson; [2021]
    Nyckelord :Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

    Sammanfattning : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. LÄS MER

  7. 15. Cooperation for Heat Recovery : A Case Study on Heat Utilization From a Supermarket Refrigeration System

    Master-uppsats, KTH/Energiteknik

    Författare :Edwin Andersson; [2021]
    Nyckelord :Heat recovery; cooperation; supermarket; refrigeration system; CO2; Värmeåtervinning; samverkan; livsmedelsbutik; kylsystem; CO2;

    Sammanfattning : The study looks at heat recovery of a refrigeration system in a supermarket where the heat was supplied to apartments in the same building. Such a system requires cooperation between the supermarket owner and the property owner, with both having different motives. LÄS MER
