Definitions
- the cooling unit (of whichever chosen type) is arranged inside the cold-storage room generally proximate to the ceiling and one or more ventilation apparatuses are connected to it and are arranged so as to convey upward the cooled air, up to the ceiling, to then make it flow on said ceiling due to the Coanda effect until the opposite wall is reached, and then allow it by gravity to move progressively toward the floor, thus ultimately affecting the entire cold-storage room.
- the aim of the present invention is to solve the problems described above, providing a refrigeration apparatus that ensures good temperature uniformity in a cold-storage room.
- Another object of the present invention is to provide an apparatus that allows practical methods for defrosting the cooling unit, i.e., for the periodic activity of melting the ice that indeed tends to form on the unit.
- Figure 1 is a partially sectional lateral elevation view, taken along a vertical plane, of the apparatus and of the cold-storage room according to the invention
- the reference numeral 1 generally designates a refrigeration apparatus of cold-storage rooms 100, which comprise at least one environment 101 to be kept at a predefined temperature.
- the environment 101 is completely thermally insulated and delimited by masonry structures of adequate thickness.
- the windows 3 and 4 (by choosing appropriately the installation site of the chamber 2 and of the apparatus 1 in general) can be arranged so as to be connected (themselves and therefore the space inside the chamber 2) to the environment 101 to be refrigerated, so as to allow the exchange of air between the latter and the chamber 2 itself.
- the windows 3, 4 can face directly the environment 101 (in practice, as in the accompanying figures) or be connected to the latter by means of additional connecting ducts.
- the chamber 2 can be arranged proximate to the ground or in any case at a low elevation, further facilitating the work of operators and maintenance technicians and reducing or eliminating the risk of dangerous falls.
- each window 3, 4 is associated with a respective closure element, which can be activated selectively (automatically or manually) in order to cause the temporary transition to a configuration for thermal insulation of the chamber 2 (with respect to the environment 101 of the cold-storage room 100) in order to allow the execution of periodic defrosting procedures.
- each closure element comprises a door 11 which is made of thermally insulating material, preferably of the fanlight type. It is specified in any case that each door 11 can be arranged horizontally or in another manner and/or be of another type (a gate that is operated in various manners and optionally even by the air stream, a curtain made of more or less heavy fabric, which acts as a thermal insulator, etc.), without thereby abandoning the protective scope claimed herein.
- the autonomous apparatus can be activated temporarily at the thermal insulation configuration so that the frame can heat the corresponding gaskets arranged along the perimeter of the respective windows 3, 4, preventing their freezing.
