Definitions

  • the present invention relates to a system for refrigeration of perishable goods.
  • the present invention relates to a system for refrigeration of perishable goods, such as foodstuffs contained within an insulating room.
  • Coibentante cells are known in the art within which it is present a cooling member, comprised of a frigorific circuit with the aid of one or more fans suitable to make air circulating so as to increase the convection coefficient within the cell.
  • Applicant has faced up the problem of realising a system for refrigeration of perishable goods, already at optimum preservation temperature, maintaining temperature inside the space wherein goods are provided substantially constant for rather long periods and/or in case many accesses to the space occur.
  • An aspect of the present invention concerns a system for refrigeration of perishable goods contained within a space comprising a refrigeration group, provided inside said space, and comprised of a plurality of modules associated each other, each one of which comprising at least a tubular inner element within which a frigorific fluid is contained, each module being conformed as an outer tubular element realising, along which said at least one inner tubular element, a gap within which a fluid is inserted determining thermal capability of the refrigeration group, characterised in that each module comprises a support in each lower part in which said inner tubular element engages, the refrigeration group being associated with said space in such a way that a sufficient gap is present between the group and a wall of said space.
  • system according to the present invention can be applied to a container body, equivalent to a insulating cell, such as loading space of motor transport means, a container, placed on board a vehicle.
  • Container body has inside a room provided with walls, which are thermally insulated according to the standard techniques, so as to define an inner space permitting the introduction of goods to be preserved.
  • System comprises a refrigeration group 3 that is for example positioned close to the ceiling of said space 2.
  • Refrigeration group can be as well positioned on one of the container walls.
  • said group is fixedly jointed, for example by a pair of brackets 31, to the space or container walls, so as to leave a gap between ceiling and upper surface of the refrigeration group so as to make air to be cooled passing.
  • refrigeration group is associated with said space in such a way that a gap is present between the group surface and a wall of said space.
  • refrigeration group is provided with opposed ends of a pair of shaped supports 32 inserting between said brackets 31.
  • Refrigeration group comprises a plurality of refrigeration modules 33, preferably smooth both on the upper and on the lower portion.
  • each module is provided with a support 35 preferably comprised of plastics.
  • Each refrigeration module is conformed as an outer tubular element, preferably at least an inner tubular element run inside by a frigorific fluid.
  • An embodiment is shown in figure 1, in which tubular elements inside each module and run by a frigorific fluid are two, an upper one 36 and a lower one 37 juxtaposed each other.
  • Said inner and outer tubular elements create a gap 38 within which a fluid (e.g. water) is introduced, determining thermal capability of the heat exchanger.
  • Inner tubular elements have radial fins 39 further promoting thermal exchange.
  • Inner tubes are connected each other by one of said fins and further a radial fin associated with the lower tube introduces within a seat 40 realised on the module base, particularly on the above mentioned support 35, safely and efficiently constraining the tubes to the module.
  • Inner element tubes 36 and 37 are preferably connected each other by a curved portion 41 so as to obtain a passage of the inlet and suction refrigerant gas, as shown in figure 6.
  • Refrigeration group is comprised of a plurality of modules provided side by side and having such a length to correspond to the loading space length or to the height of a wall of said space.
  • System further preferably comprises an air conveyor 5, suitable to force air ventilation inside the gap existing between refrigeration group and wall to which it is associated the same group.
  • Operation function of the system according to the present invention is based on the capability of transferring in thermal accumulators units of refrigeration necessary for autonomous operation for required travel period, obtaining a thermal autonomy of at least five days.
  • function of charging refrigeration group is obtained by a single recharge unit, for example an electrically supplied unit, not provided on board the vehicle.
  • a single recharge unit for example an electrically supplied unit, not provided on board the vehicle.
  • system can have an autonomy even longer than six days at a temperature between 0° and 6°.
  • Figure 5 shows a graph of temperatures within an insulating cell obtained experimentally, said cell being provided with the group according to the present invention, for a period of about ten hours.
