Abstract: A cooling device is in the form of a refrigerator or a point-of-sale display cabinet that is open on one side and is used to store and present perishable goods. The device is fitted with a unit for lowering the interior temperature in relation to the ambient temperature. The inner wall is constructed in two stages, the outer layer consisting of a thermal insulation layer having a heat conductivity <1 Watt/K, and the inner layer consisting of an at least partially coated mixture consisting of a phase transition material and graphite, which covers at least part of the inner wall and is used as a cold accumulator layer.
