Definitions

  • the present invention relates to a refrigeration plant structure for supplying pressurized refrigerant which is expanded at refrigeration stations.
  • the present invention is particularly applicable to refrigeration systems used in department stores.
  • stations or groups of stations to be refrigerated there are generally, on one level, several stations or groups of stations to be refrigerated: cold rooms placed out of reach of the public, bins and freezer cabinets arranged in the sales area, and various bins refrigeration at temperatures above 0 ° C, for example for butcher's, fishmonger's, fruit and vegetable, cheese, fresh produce, etc. stalls.
  • FIG. 1 very schematically and incompletely shows an example of a building arrangement serving as a big box store.
  • This building includes a sales area 1 accessible to customers in which there are numerous display shelves 2 carrying goods offered for sale.
  • the sales area includes cold zones 3, for example display cases, cabinets or refrigerated containers containing frozen products accessible to customers.
  • the building of a big-box store also generally comprises on one of its long sides a service area 10 comprising for example a storage region and cold rooms 11. It is often found at the border between the service area and the sales area of the fresh produce sales outlets such as a butcher counter 12 and a cheese counter 13.
  • a centralized engine room containing a refrigeration plant serving as a source of refrigerant for all regions is used. cool.
  • This machine room or technical room 15 is shown by way of example in a corner of the building. This technical room is also for reasons of economy of space often arranged halfway up the store, supermarkets commonly comprising a single level in the sales area and two levels in the service part, the second level comprising for example offices.
  • This technical room 15 includes the means necessary to supply a pressurized refrigerant, for example a compressor 16 with its motors and supply means.
  • This compressor is associated with a condenser 17 generally arranged outside the technical room, for example on the roof and associated with ventilation means for cooling it, this condenser returning the fluid under pressure to a reservoir 18 from which it is transmitted by pipes 19 to the various stations to be cooled, each of which is associated with a pressure reducer 20 of which only one is shown at the entrance to one of the cold rooms Pipes 21 for the return of the refrigerant to the compressor 16 possibly via d 'an evaporator are also provided.
  • the various pipes 19 for refrigerant under pressure possibly come from several separate refrigeration machines arranged in the engine room.
  • the present invention relates to a new structure of central refrigerant supply particularly suitable for large sales areas on one level.
  • the present invention provides a refrigeration plant according to claim 1.
  • the present invention makes it possible to solve practically all of the aforementioned drawbacks of prior machineries and their establishment in large sales areas.
  • the tunnel boxes constituting the refrigeration unit according to the invention can easily be placed above the roof, at the level of the support posts of the building structure, the refrigerants being brought to the places of use by pipes. verticals extending along these posts. If you want to change the location of the various refrigeration stations in a large store, it will be enough to move the refrigeration unit placed at the roof level to another pole of the structure to adapt it to the new location of the stations refrigerators.
  • the present invention provides for bringing together all the elements of a refrigeration unit in a box 30 made up of elementary modules 31, 32, 33, 34 assembled by assembly means 36, 37, 38.
  • the first module 31 contains only an air filter 40.
  • the second module 32 comprises electrical cabinets 41, compressors 42, and a reservoir of compressed refrigerant fluid 43.
  • the third module 33 comprises a condenser 44.
  • the fourth module 34 comprises an air extraction turbine 45 next to which a drive motor 46 has been shown.
  • all of the modules once assembled form a transportable box in one piece if desired.
  • This can be useful for moving the refrigeration unit according to the invention, for example as indicated above in the case where it is desired to reshape the layout of the sales area of a department store.
  • each of the modules 31 to 34 can be associated with a gripping element such as a ring 48 or any other equivalent means to allow each of these modules or all of the modules to be moved, for example by means of a crane.
  • the various modules comprise, as shown in the figure, upper and lower walls, front and rear, but no side walls between the modules which all communicate once assembled and constitute a box-tunnel.
  • a single air circulation caused by the turbine 45 at a variable rate as a function of atmospheric conditions simultaneously makes it possible to cool the engine room itself, that is to say the compressors 42, and the condenser (s) 44
  • flaps for orienting the air flow for example, in module 32, to cool more particularly the cylinder head heads of the compressors 42.
  • Two centrifugal turbines can be used as extractor.
  • One, with variable flow, is controlled so that the internal temperature of the box remains constant, in particular at the level of the condenser or condensers, whatever the external temperature.
  • the internal condensing pressure will be constant and the refrigerants will be sent at constant temperature and pressure regardless of the external temperature.
  • the second turbine serves as a backup in the event of a breakdown or abnormally high outside temperature.
  • the air rejected by the extractors can be returned to the store to heat it, the air introduced into the box can come, at least partially from inside the store.
  • module 32 electrical cabinets 41, compressors 42 and a storage tank 43
  • these various elements could be arranged separately in independent modules or be assembled with other components of the system. Assembly will be dictated by considerations of mounting convenience, maximum tolerable weight for individual modules, ease of access, etc.
  • a refrigerant supply unit 30 can advantageously be arranged on the roof of the building of a department store, for example in connection with the support posts of the roof, the refrigerant entering and leaving by pipes going down and going up along these posts.
  • the heat released by the compressors and the condenser can optionally be recovered to allow circulation of hot air or a heated fluid for heating the sales premises or the distribution of domestic hot water.
  • a box will be associated with each group of stations to be refrigerated to avoid horizontal transfers at ground level of the refrigerants.
  • the installation in addition to its advantages of flexibility of use and assembly also makes it possible to reduce the lengths of pipeline between the places of use and the refrigeration unit and therefore to reduce the quantity of refrigerant to be provided as well as the losses thermal.
  • a monochlorodifluoromethane (R22) can be used as the refrigerant rather than a fluid of the type (R502) more commonly used but which has harmful characteristics for the environment.
