[0006] The obj ective of the present invention is to provide a refrigeration unit with articulated rods that avoids the drawbacks of the prior art .

[0007] This obj ective is achieved by means of a refrigeration unit , comprising a bottom cold side , an upper hot side and an insulation between said hot and cold sides ; said cold side comprising at least two cold side fans mounted on a base plate and at least two evaporators disposed on opposite sides of the bottom cold side ; a structural support disposed below the insulation; side plates disposed above the base plate , each side plate further disposed transversally between the evaporators , wherein between the base plate and the side plates there are at least two articulated rods .

[0008] Additionally, the refrigeration unit according to the present invention consists of the fact that the base plate comprises lower receiving portions , and each of the at least two articulated rods comprises a lower intermediated portion mounted to one of the lower receiving portions by means of a screw .

[0009] In addition, the refrigeration unit according to the present invention consists of the fact that the side plates comprise upper receiving portions , and each of the at least two articulated rods comprises an upper intermediated portion mounted to one of the upper receiving portions by means of a screw .

[0010] Further, the refrigeration unit according to the present invention consists of the fact that the lower intermediate portion and the upper intermediate portion are j oined by an articulation, said articulation provided inthe upper end of the lower intermediate portion and in the lower end of the upper intermediate portion .

[0011] The advantage of the present invention lies in the fact that the articulated rods between the plate and the structural support allow to open the refrigeration unit without having to disassemble it . Hence , by using such articulated rods , the maintenance operation of the refrigeration unit becomes much simpler and faster .BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 illustrates a perspective view of the refrigeration unit 100 in a closed state according to the present invention. This refrigeration unit 100 is preferably installed at the roof of cold rooms and walk-in chambers located, for example, in supermarkets, pharmacies, and other places that need to refrigerate products. According to Figure 1, said refrigeration unit 100 comprises a bottom cold side 200 and an upper hot side 300. Preferably, the refrigeration unit 100 is installed at the roof in a way that the cold side 200 remains inside the cold room or walk-in chamber and the hot side 300 remains outside .

[0019] Figure 2 illustrates a perspective exploded view of said cold side 200 according to the preferred embodiment of the present invention.

[0020] According to Figure 2, there is an insulation 210. The insulation is disposed between the cold 200 and hot 300 sides.

[0021] Still according to Figure 2, the cold side 200 further comprises a structural support 220 disposed below the insulation 210.

[0022] Further according to Figure 2, the cold side 200 comprises evaporators 230 disposed on opposite sides of the bottom cold side, and side plates 250 disposed above a base plate 240, each side plate 250 further disposed transversally between the evaporators 230. According to a preferred embodiment of the present invention, two evaporators 230 and two side plates 250 are used.

[0023] According to Figure 2, the cold side 200 further comprises cold side fans 240A mounted on the baseplate 240 . According to a preferred embodiment of the present invention two cold side fans 240A are used .
