  • the present invention relates to a compact refrigeration module based on the compression of refrigerant and integrated by at least one compressor, at least one evaporator, at least one condenser, at least one refrigerant expansion device.
  • This compact refrigeration module differs from compact refrigeration modules belonging to the current state of the art in that it has a general composition especially suitable for installation in refrigeration equipment of restricted dimensions.
  • modules or refrigeration units based on refrigerant compression are of particular interest, that is, modules or refrigeration unit consisting of at least one refrigerant compressor, at least one condenser , at least one expansion device and at least one evaporator. Even more punctually, compact refrigeration modules are of particular interest.
  • Patent document US7703295 describes a modular refrigeration unit integrated by a coolant compressor, a condenser, a expansion, an evaporator and fans associated with the condenser and evaporator.
  • Patent document US7874168 also describes a modular refrigeration unit integrated by a refrigerant compressor, a condenser, an expansion device, an evaporator and fans associated with the condenser and evaporator.
  • the evaporator if the evaporator is arranged, they are separated and delimited by means of a horizontally arranged thermally insulating wall. This means that the "hot side” and the “cold side” are arranged in different horizontal planes and, more particularly, it is observed that the "cold side” is arranged on the "hot side”.
  • a compact refrigeration module comprising a first portion which, in turn, comprises at least one hermetic compressor, at least one condenser associated with a ventilation medium and at least one expansion device; a second portion comprising at least one evaporator associated with a ventilation means; said first portion being disposed between a base and an intermediate assembly structure, and said second portion being disposed on the opposite side of said intermediate assembly structure.
  • the compact refrigeration module in which said intermediate assembly structure is made of thermally insulating material and comprises at least two front openings and at least one latero-posterior wall that define the circuit of the main air flow; at least two frontal projections that define the evaporator mounting seat associated with the ventilation medium and at least one recess provided with an orifice that define the drainage medium of the second portion.
  • the present invention provides for a compact cooling module in which the recess provided with a orifice is centrally arranged in the evaporator mounting seat defined by the two frontal projections.
  • this invention provides a compact cooling module that comprises a thermal protection structure disposed in the front region of the first portion and a thermal protection structure contouredly disposed in the second portion.
  • a compact cooling module is provided in which the thermal protection structure has front openings aligned with the front openings of the intermediate assembly structure.
  • the compact refrigeration module has a dimensional relationship between the base thickness and height of the compact refrigeration module, less than 0.3.

  • Figures 5 and 6 illustrate, in detail, the assembly and spatial division between the second portion and the first portion that integrate the compact cooling module
  • Figure 7 illustrates, in particular detail, the positioning of the components that integrate the second portion in the intermediate assembly structure
  • Figures 8, 9 and 10 illustrate, in detail, said intermediate assembly structure that integrates the compact refrigeration module
  • Figure 11 illustrates, in schematic section, the general topology of the compact refrigeration module.
  • a compact refrigeration module 1 comprising a first portion, said first portion comprising at least one hermetic compressor 2, at least one capacitor 3, this condenser 3 associated to a ventilation means 31 and at least one expansion device 4. Furthermore, the compact cooling module 1 comprises a second portion, this second portion which, in turn, comprises at least one evaporator 5 associated with a ventilation medium 51 .
  • Said first portion which, for the case of a compact cooling module 1, can be commonly called “hot side", since the constituent elements of it generate a noticeable heat.
  • the second portion can be commonly called the “cold side” since the constituent elements remove heat from the surroundings, which leads to the sensation of a drop in temperature. This fact denotes the importance of adequate thermal insulation between these portions.
  • Figure 1 shows the general structure of the compact refrigeration module 1 in its assembled configuration, that is, operation configuration.
  • the module's housing has a protective and aesthetic function and can be made of different materials, such as plastic or metal.
  • openings in the said housing which are preferably positioned close to the ventilation means (detailed later in this report) to facilitate air circulation and thermal exchanges with the environment.
  • the thermal protection structure 72 has front openings 721 aligned with the front openings 8 of the intermediate assembly structure 62.
  • the front openings 721 are specially positioned to structure a "channel" "of air passage, this because this structure aims at maximum efficiency in the thermal changes that must be carried out by the evaporator component 5.
  • said intermediate assembly structure 62 is preferably made of thermally insulating material. It can be seen, mainly in figures 2, 5 and 6 that said intermediate assembly structure 62 separates said first portion of module 1 from the second portion thereof, that is, structure 62 is responsible for thermally insulating the "hot side "of module 1 on the" cold side "of it.
  • the intermediate assembly structure 62 presents geometry composed of walls and openings that aim at saving space, coupling components, adequate air circulation and insulation capacity between the portions of module 1.
  • the intermediate assembly structure 62 comprises at least two front openings 8 and at least one latero-posterior wall 81 that define a circuit of the main air flow.
  • Said intermediate assembly structure 62 also comprising at least two frontal projections 82 that define the mounting seat of the evaporator 5 associated with the ventilation means 51 and at least one recess 9 provided with an orifice 91 that define the drainage means of the second portion, "cold side”.
  • thermal protection structure 71 With regard to the thermal protection structure 71, it is seen that this is arranged in the front region of the first "hot side” portion and the thermal protection structure 72 is contourably arranged in the second "cold side” portion of the module refrigeration compact 1. Both thermal protections 71 and 72 aim to adequately isolate regions with different temperatures, even module 1 having dimensional restrictions.
  • the recess 9 is provided with an orifice 91 and is centrally arranged in the mounting seat of the evaporator 5.
  • the evaporator 5 is securely coupled in the orifice 91 region, which region it features an assembly seat defined by two frontal projections 82. It is worth noting that the shape of the frontal projections 82 can vary according to the dimensions of the evaporator 5.
  • the evaporator 5 is positioned between the frontal projections 82 over hole 91 provided in the recess region 9. In this way, any leakage of fluid is directly directed to hole 91 , preventing this fluid from reaching other components of the module.
  • FIG 11 a view of the recess 9, which also shows the evaporator 5 and the ventilation means 51 in section.
  • the extension of the duct 92 which connects the orifice 91 to the lower portion of the module 1.
  • Means of storage of leaked fluid can be provided at the opposite outlet of the orifice 91.
  • the relationship between the base thickness 61 and height of the compact cooling module 1 has values between 0.2 and 0.3.
  • the thickness of the base 61 of the module 1 is 120mm and the height of the module 1 is 445mm, and for these specific dimensions, the relationship between the thickness of the base and the height of the module is 0.27.
