Abstract

PURPOSE: To prevent a vapor condensation of a glass wall, to save power expenses and to reduce an operating cost by diffusing warm air heated by a condenser to a front surface of the wall under the guidance of an air supply duct. CONSTITUTION: At the time of operating the open showcase, a glass wall 21 exposed with cold air diffused from a cold air outlet 5a is cooled. Meanwhile, the atmosphere fed toward a condenser 8 by a fan 13 derives heat of the condenser 8 to become warm air, which is guided from an air outlet 16b toward the wall 21 to heat an outside glass plate 21a. Accordingly, the plate 21a receives the cold air at the wall 21. Thus, even if a heater is deleted, its surface is not vapor condensed, but a commodity can be held in an easily observed therethrough and, the case can save much power dissipation amount by deleting the heater.
