Definitions

• the invention relates to a container cooling rack.
• Such container refrigerated shelves are technologically very similar in technology to conventional refrigerated shelves, which are equally intended in particular for commercial use in the food industry, such as for sale of meat, vegetables, fruit or dairy products.
• Such refrigerated shelves, as well as container refrigerated shelves comprise a goods space that is open to at least one user side for access to goods.
• refrigerated shelves can have glass doors or the like here, which, however, is naturally not provided for in container refrigerated shelves.
• Other refrigerated shelves are in themselves open during the opening hours of corresponding stores that hold such refrigerated shelves, so that customers can directly and directly take out goods. For energy-related reasons, it may be provided that energy losses are minimized by covers, such as roller blinds and the like, outside of business hours.
• the conventional refrigerated shelves comprise a framework surrounding the goods space with a ceiling element and a wall, wherein in the ceiling element along the open or apparent user side a cold air supply for the goods space or in conventional refrigerated shelves is provided for a cold air curtain.
• the cold air supply is provided with a cold air supply comprising a arranged at least partially in the conversion and in the ceiling element main air duct with an air intake and arranged in the main air duct fan and arranged in the main air duct cold point of a cooling unit.

• CONFIRMATION COPY Container refrigerated shelves do not have floor trays, such as those found in conventional refrigerated shelves.
• the invention is based on the basic knowledge that in order to increase the energy efficiency of container refrigerated shelves, a suitable air curtain that forms on the user side of the goods, is advantageous, in particular for this purpose, a corresponding intake, which, if possible, the cold Air of the cold air curtain with as little warm room air sucks in this regard is an advantage.
• a bottom plate with a support for the container and with the air intake is provided in the bottom region of the container cooling shelf, wherein the air intake extends parallel to the cold air supply.

This avoids that the corresponding wheels must be moved up to get to the bottom plate, so that a loading of the receptacle for operators over conventional container refrigerated shelves is not difficult.
• a header in front of the bottom plate may be provided with a continuous or with a widened air intake similar to the front end, which can be removed from the assembled and reassembled after loading. In practice, however, a continuous floor slab has proven to be relatively efficient and reliable.
