オープンシヨーケース。[Scope of Claim for Utility Model Registration] A cold air circulation duct is formed inside the case body, the circulating air is cooled by a cooler disposed within the cold air circulation duct, and the circulating air is blown out from the air outlet to open the case opening. In the refrigeration/refrigeration open case that is configured to form a cold air curtain, at least a portion of the cold air circulation duct is divided into two-layer passages, a cooler is provided in each passage, and the cooler is connected to a refrigerant. In addition to connecting each cooler in parallel to the circuit, each cooler can be defrosted independently by introducing high-temperature gas, and after defrosting, the liquefied high-temperature gas is reused for cooling via capillary tubes to reduce pressure. A freezing/refrigerating open case featuring a defrosting mechanism.
