Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a van type refrigeration vehicle suitable for transporting flowers and the like.

[0002]

[Prior art]

 As shown in FIG. 1, a conventional van-type refrigeration vehicle has an evaporator a provided at the front of the refrigerator, and cool air from the evaporator a is blown from a ceiling duct b by a forced fan to cool the refrigerator. After that, the temperature was maintained at a predetermined set temperature by the forced circulation system in which the air was returned to the evaporator a through the floor ventilation rail c. In such van type refrigeration vehicles, in order to improve transportation efficiency, if a shelf is installed in the middle of the storage room and flowers are stacked on the shelf and on the floor surface for transportation, the flowers are dried. However, there is a problem that the vitality of flowers on the floor is lost. This is because the circulation of cold air is not evenly distributed in each room divided by the shelves, and the cold air directly hits the flowers. In view of such a problem, the present applicant has proposed one solution in Japanese Patent Application No. 3-110464. With this, cold air is blown out only to the vicinity of the wall surface of the refrigerated vehicle, and this is also sucked in from the vicinity of the wall surface to forcibly circulate the cool air. This structure makes it possible to manage the product temperature softly by avoiding the direct contact of cold air with the cargo such as flowers by keeping the air near the center of the warehouse.
