Refrigerated super-showcases are used for displaying and preserving food products at places such as supermarkets_ It is important that trouble occurring in showcases is anticipated in advance. However, there exist difficulties due to the existence of numerous types of units, inconsistent characteristics, and too few sensors, all of which make it hard to develop a standardized method of evaluation for determining if a showcase is operating correctly. In this paper, we propose a new method of occurrence-forecast of trouble for showcases by using criteria adapted to environmental conditions. This method is based on the characteristics of showcases that their operating state is influenced by environmental conditions. We have evaluated this method from field data of a supermarket. The result leads us to convince that this method can be put to practical use.
