IR Thermography has been widely used to measure air temperature in many application fields. Usually screens or targets are located in the region of interest in such a way to minimize the perturbation of the flow under investigation. In this work, this technique is applied to map the air distribution inside the cold curtain of an open refrigerated display cabinet (ORDC). The performances of the commonly used black cardboard and a net-screen are studied in different conditions by a CFD analysis.
