Resumo: | This paper reports the experimental results with an open multideck display case with dual air curtain. Manufacturers seek during the design phase of the equipment to certify its suitability to the testing standards with the lowest energy consumption and ensuring food safety. The testing standard ISO 23953 is usually followed to determine the thermal cooling load. The thermal cooling load depends on the procedure to set the external air velocity. According to ISO 23953, the mean horizontal air velocity, with the refrigerated display case switched off, shall be 0.2 m s-1. This paper reports experimental test results where the initial procedure of setting the air velocity followed two different methods. Considering that (1) the display case is initially switched off as required by ISO 23953 and (2) the display case is initially switched on and the external air velocity is adjusted to the required level using auxiliary fans. After reaching steady state conditions, the 24-hour tests began with the display case switched on. |
