Definitions

  • the invention relates to a heat-exchange system of sectional, modular type with limited overall dimensions, which is particularly suitable for room air conditioning.
  • Modular heating systems are known, so-called radiant floor heating, formed of flat and thermally insulated modules facing towards the floor, provided with means for quick and removable reciprocal connection, so as to form a coating or panel with the required dimensions and shape.
  • Such modules have an upper face made of a material with a good ,heat conductivity, usually metallic material, and is such as to be coated with a material which has good heat dissipating properties, providing a surface that can be walked on and has suitable mechanical resistance and aesthetic features .
  • the radiant floor heating manufactured in this way has modules arranged for producing heat by exploiting incorporated electrical resistances, supplied at low voltage for reasons of safety.
  • the modules comprise internally channels or conduits provided on an upper metallic coating that are then covered by the walk-on surface, pipes of the type used for indoor- floor heating, in which a fluid, for example glycolated water, is circulated at low pressure and at a temperature no higher than 40 0 C, coming, for example, from a heat exchanger and a heat pump which in the summer can be used also for cooling the room via fan coil and/or dehumidifying systems.
  • a fluid for example glycolated water
  • the aforesaid radiant floor heating systems are, for example, intended for conference halls, trade-fair stands or open-air events or for places of particular artistic, cultural and daunting interest, for example churches, museums, historic buildings, art galleries and other places, where the spaces to be conditioned often involve extensive horizontal and vertical areas and in which there is the need to limit to a few metres the height of thermoconvective movements which could convey aerial pollutants upwards.
  • Radiant floor heating systems with electrical resistances involve high electrical energy consumption, inasmuch as the heat is produced by the Joule effect.
  • electrical transformers are necessary that are intended to produce low voltage and very high electrical currents in order to be able to deliver the power necessary for supplying even very large surfaces.
  • the liquid circulation pipes In order to limit the thickness of the modules, the liquid circulation pipes generally have a reduced diameter, thus determining modest conditioning liquid flow values, and, vice versa, great load losses. Further, both, the known radiant floor heating systems are not suitable for being located other than on the floor, for example on vertical walls or on ceilings.
  • An object of the present invention is to improve the modular heat-exchange systems for conditioning buildings, in particular by increasing the versatility and flexibility of use thereof .
  • Another object is to obtain a modular heat-exchange system the heat exchanger modules of which can be assembled together and be subsequently dismantled in a rapid, simple and easy manner, separately and independently of one another.

  • the connecting means comprises a connecting element having a shape that is complementary to and is insertible into, said housing and is provided with through openings for flowingly connecting corresponding openings of said two adjacent heat exchanger modules .
  • the locking means When, the locking means is arranged inside the housing it is drivable so as to reversibly lock together said two heat exchanger modules.
  • the locking means comprises, in particular, a locking bush that is rotatably housed in a central recess of the connecting element and is provided with abutting means arranged for engaging, in a locking position, further abutting means of said seats.
  • the abutting means and/or the further abutting means are shaped in such a manner that as said locking bush rotates from an inserting position, in which said abutting means is disengaged from said further abutting means, to the locking position, the adjacent heat exchanger modules are progressively clamped together and to said connecting element .
