１項記載の冷蔵オープンショーケース。(1) A refrigerated oven in which a cooling air curtain and a guard air curtain covering the outer surface of the cooling air curtain are formed on the opening surface of the case to block outside air and maintain the inside of the case at a low temperature. In the case, a part of the cold air circulation duct forming the cooling air curtain is divided into two-layer passages, and each passage is provided with a cooler.
- A refrigerated open showcase characterized in that an inlet refrigerant pipe of a cooling device is provided with an expansion valve and a solenoid valve located upstream of the expansion valve. (2) The solenoid valve is controlled by a timer control circuit to automatically open and close at predetermined intervals, alternately interrupting the cooling operation, and performing off-cycle defrosting. Refrigerated open showcase as described in Scope 1.
