Definitions
- the present invention relates to a refrigeration unit which comprises a housing compartment for at least one compressor unit, this compartment being delimited by a frame capable of supporting several units ventilation modules juxtaposed together above the compartment.
- ventilation unit should be understood to mean batteries heat exchange system and any corresponding forced ventilation systems which, associated with the compressor unit, constitute the refrigeration unit, that the latter works in a refrigeration installation proper or in a heat pump.
- the invention relates to a group of the type defined above, characterized in that said frame comprises support means to support all of the modular units that project overhang on this built.
- part of the ventilation unit protrudes from the frame has advantageous effects on the functioning of the group, in the sense that the circulation of air through the protruding units is improved, since the air flow at through these units arranged in overhang is not hampered by the presence of the frame.
- the invention makes it possible to improve the distribution of the weights of the refrigeration units.
- the barycenter of the structure is substantially centered relative to the plane, typically located in the lower part at the level of the compartment that houses the compressor units.
- all of the units modular ventilation projects in a substantially symmetrical overhang on either side of the frame.
- Group 1 comprises, in position lower, a frame 3 which delimits a compartment 4 for group accommodation motor-compressors 5 of the installation.
- the frame 3 has a substantially rectangular shape and is normally produced by joining together metal profiles formed by folding under sheet metal pressure.
- the frame 3 comprises a rectangular base frame 6 formed a pair of longitudinal elements 9 and a pair of transverse elements end 11 connected together, preferably formed by section profiles transverse in C.
- section profiles transverse in C.
- the section of these profiles may be different, with appropriate calculation of dimensions, although this section in C represents a choice prefer.
- the length of the longitudinal elements 9 is advantageously chosen to so as to take advantage of the length of the profiles achievable by folding under pressure of sheet metal, which typically corresponds to about three meters, so that each is composed of a single piece.
- the profiles which constitute the elements 9 do not require the execution of cutting operations or the assembly of profile parts, so they are optimized in terms of structural strength, weight and Cost.
- profiled elements auxiliaries 10 for example with an omega cross section, which extend parallel to the transverse elements 11 and make it possible to fix the groups motor compressors 5 so as to rigidly connect them to the frame 3.
- each of the longitudinal elements 9 are also rigidly connected several vertical uprights 13, for example three uprights 13 for each element 9, advantageously made using box profiles.
- a frame 20 intended to support several modular units of ventilation 24, juxtaposed together above compartment 4.
- the assembly constituted by the modular units 24 projects in overhang with respect to the frame 3, preferably in a substantially symmetrical manner on either side of the frame 3.
- a group 1 control panel designated by the reference number 26 in Figure 1.
- the support frame 20 comprises several crosspieces 28, rigidly connected by their opposite ends to a pair of respective uprights 13, each cross member 28 being produced, for example using a profile which has a cross section in C. Above the crosspieces 28, and in line with their ends, are then fixed two parallel beams 30, intended for the assembly of the units ventilation modules 24.
- each spar 30 has a cross section of the general shape of an S, so as to present a folded wing 30 a , for fixing the lower part of a battery or of a vertical ventilation unit 32 of the condensers, and another folded-down wing 30 b , inclined with respect to the wing 30 a , used for fixing the lower part of an inclined battery 34.
- the two inclined batteries 34 are fixed to each other at their upper ends using a pair of profiles 36 juxtaposed between them, and having a substantially L-shaped cross section, so that the batteries 34 take an inverted V configuration.
- the L 36 profiles are in turn connected to the top of the batteries vertical 32 using cover and group support elements ventilation, known per se.
- respective section reinforcement profiles transverse in C are fixed to the upper ends of each battery 32, 34, of so that these batteries are connected to the rest of the structure through these profiles.
