During the daily operation of food stores, consumers and repository personnel pass in front of VORDC and frequently remove or place food products on shelves. This movement is part of the trade, however it has consequences on the thermal performance of the VORDC. Each interference drags or breaks the air curtain of the equipment resulting in the modification of air flow and promoting the ambient air thermal entrainment that consequently changes the equipment's operative conditions. This paper reports the results of experimental tests performed according to ISO 23953 in a VORDC to assess the thermal performance of the air curtain when subjected to the systematic crossing by a solid body simulating people arms. This solid body consists on a moving electromechanical device composed by a set of pneumatic cylinders that allows several patterns of air curtain interference.engVertical open refrigerated - VORDCjournal article
