Claims

[Scope of utility model registration request]

The interior of the main body, which has an opening for entering and exiting products on the front side, is divided by a duct board into a product display room and a cold air circulation path in which a blower and a cooler are installed. In a refrigerated open air case in which an air outlet and an inlet facing the upper and lower ends of an opening are formed and the opening surface is closed with a cold air curtain, the cold air circulation air passage is divided into a plurality of sections in the longitudinal direction by an air passage partition plate. , for each compartment, there are multiple refrigerant pipes that span the coolers of other compartments, and in the case of two refrigerant pipes, the cooler is formed with pipes of different lengths, and the cooling A blower corresponding to the container is provided, a solenoid valve is provided on the inlet side of the refrigerant flow path of each refrigerant pipe, and the product display room is divided in the longitudinal direction with internal partition plates corresponding to the divisions. A refrigerated open case.
