Abstract(s)
This paper reports the results of experimental tests performed according to ISO 23953 in vertical
open and closed refrigerated display cabinets (VORDC vs. VCRDC). Tests were performed at a
mild climate class (n. º 3: T=25°C; φ=60%) and a tropical one (n. º 6: T=27°C; φ=70%). The direct
energy consumption is 46% higher at VCRDC due to the heated glass doors frame and defrost
heaters. The product simulator temperature is higher and more stable at VORDC. The highest
product simulator temperature is lower (-1.4°C) at the VCRDC and less stable (+2.7°C variation)
due to the opening doors period. The total mass of condensed water at the evaporator is reduced
87% and the total heat load is 77% lower at the VCRDC. Thus, the estimated total energy
consumption is reduced 42%. Given the current concerns with energy consumption and
sustainability of the heat exchange processes, the VCRDC provide the best solution.
