  1. 1. Heat Export from Supermarkets : Refrigeration Systems Field Measurements and a Techno-economic Analysis

    University essay from KTH/Energiteknik

    Author : Julia Linnea Hildur Almebäck; Rebecka Magnius; [2022]
    Keywords : Heat Recovery; Heat Export; Supermarkets; Refrigeration Systems; CO2 Transcritical Booster Systems; Energy Efficiency; Värmeåtervinning; värmeexport; livsmedelsbutiker; kylsystem; CO2 transkritiskt boostersystem; energieffektivitet;

    Abstract : Supermarkets have a high energy demand where almost half of the energy is used within the refrigeration system. The refrigeration system utilises a cycle where heat is taken and rejected. The rejected heat could be recovered and utilised for other purposes, such as covering internal heating demand or be exported to other facilities. READ MORE

  3. 2. Field Measurements and Modelling Analysis of Integrated Ice Rink Energy Systems

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

    Author : EMIL BERG-LUNDFELDT; [2020]
    Keywords : Heat recovery; energy efficiency; ice rink energy systems; trans-critical CO2; Värmeåtervinning; energieffektivitet; energisystem i isrinkar; transkritiskt CO2.;

    Abstract : Behrn Arena in Örebro, Sweden, is an ice rink facility where the company is interested in ways of improving their current energy system in terms of energy efficiency. Currently, district cooling is purchased to reclaim the waste heat from the ice rink refrigeration system, which is further used as a heat source for local district heating distributor. READ MORE

  4. 3. Evaluation of CO2 Ice rink heat recovery system performance

    University essay from KTH/Energiteknik

    Author : Sotirios Thanasoulas; [2018]
    Keywords : Ice rinks; CO2 as refrigerant; Heat recovery; Efficient systems; Operation control; Warm climate; Isrinkar; Koldioxid som kylmedel; Värmeåtervinning; Effektiva system; Driftstyrning; Varmt klimat;

    Abstract : Ice rinks are the largest energy consumers in terms of public buildings due to their simultaneous need of cooling, heating, ventilation, and lighting for different parts of the building which means that these facilities also have a lot of potential for energy saving. Due to the size of the cooling unit in an ice rink the refrigerant charge can become quite high, which potentially has a big impact on the environment. READ MORE
