For global warming prevention, energy saving is called for also at the supermarket or the convenience store. In this research, the visualization model of the same size as the system and form was manufactured. It changed and experimented in internal and external double air curtain velocity. The Ar+ laser light sheet was illuminated from the front of a showcase, and the flow in an air curtain and a shelf space was visualized with using dry ice mist for the tracer. PIV was used for the analysis of a flow. The swirl in a leakage and shelf space of an air curtain wore evaluated synthetically. As a result, the air curtain leakage has been reduced by making inner side wind velocity increase. Inflow on the shelf of the upper row of an air curtain was one of the causes of a leakage. It became clear that the conditions of the air curtain of a system are satisfactory.
