The authors present a study on the reduction of electric energy consumption in the process of preserving agri-food products. Refrigeration facilities used to cool various easily perishable agri-food products were examined in order to establish solutions for increasing energy efficiency in the storage process. The proposed solution provides for the combination of the refrigeration installation with step cooling, with the in-flow cooler with fan installed in the outside environment, which during the cold period of the year supplies the installation with artificial cold. The experimental results have shown that this system allows the reduction of approximately 27% of the electric energy consumption consumed annually by the existing installations.
Autorii prezintă un studiu privind reducerea consumului de energie electrică in procesul de păstrare a produselor agroalimentare. Au fost examinate instalaţiile frigorifice utilizate la răcirea diferitor produse agroalimentare ușor alterabile in vederea stabilirii soluţiilor cu privire la sporirea eficienţei energetice in procesul de păstrare. Soluţia propusă prevede combinarea instalaţiei frigorifice cu răcirea in trepte, cu răcitorul in flux cu ventilator instalat in mediul exterior, care in perioada rece a anului suplinește instalaţia cu frig artificial. Rezultatele experimentale au demonstrat că acest sistem permite reducea cu cca 27% a consumului de energie electrică consumată anual de instalaţiile existente.
