Abstract

A disinfectant, preferably ozone, is blown with the aid of the carrier phases air and water mist into the evaporation chamber (3) of the refrigerated display case (1). These measures permit disinfection of the display case in operation without any expensive dismantling of the evaporation chamber or of the cooling air channels and without having to clear the display area. Correspondingly designed display cases are used, in particular, in food stores. <IMAGE>
