5. 4. 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
