Definitions

  • the present invention relates to devices for heating or cooling interiors by means of radiators, convectors, fan coils and combinations thereof and which are traditionally used to heat rooms during the cold season and cool the same rooms during the summer season.
  • the technological apparatus presently used to exchange heat with an indoor environment traditionally include:
  • fan coils composed of finned pack heat exchangers in which the circulation of heated air is achieved by means of a fan installed in the cabinet containing the heat exchanger.
  • Cooling fan coils can work with a hot circulating fluid, in place of a cold one, so that they can also be used for winter heating.
  • the problem to be solved is to develop a single terminal unit capable of satisfying different room thermal load requirements both when the fan is on and off.
  • the device of the present invention provides an optimal solution with the application of two series-connected finned packs supplied by a single circuit that may carry, alternatively, a hot liquid for heating or a cold liquid for cooling the surrounding room. Furthermore, the device in question features a solution that permits heating through both natural and forced convection, whereby convection heating and fan cooling may be obtained from a single unit.
  • Figure 1 shows the device in the operating configuration for daytime winter heating, with the fan (4) on and hot water circulating through the heat exchange circuit (3).
  • Figure 2 shows the device in the operating configuration for convection with the fan (4) off. It may be noted that opening the front panel (5) will cause air to be circulated inside the room by means of natural convection.
  • Figure 3 illustrates the device in the summertime cooling configuration with the circulation of cold air in the heat exchange circuit (3) and the fan (4) on. It may be noted that ambient air is blown by the fan (4) across both finned packs (2; 1). In the figures each individual part is marked as follows:
