Here, too, takes place within the bottom inflow chamber 32c a change in the direction of flow of the air, but in particular a change in direction by 180 °. 13 comprises two grilles 9a for the Air inflow Z, which is on both sides of the air outlet opening 5 of the heat transfer profile 1 are arranged. A grille for the air outlet opening 5 is not shown or provided.
  • the cover grilles 9a for the air inflow Z are like the grilles 9, 11 in the embodiment according to FIG. 12 laterally on the outer wall 42 and on the Raised access floor 47, but serve here in addition to a hanging attachment of the heat transfer profile in the floor cavity 48.
  • FIG. 14 shows - similar to FIG. 6 - an arrangement of the room temperature control element according to the invention, in which this is arranged on a facade support 27.
  • the Air inflow Z is perpendicular to the facade from the room.
  • the Air flow A from the room temperature control element, which - as shown - a lateral air duct directed towards the window (glazing 29) and then guided in parallel causes should prevent the cold air from falling on the windows. This takes place in summer cooling the warm glass surfaces and thus increasing the efficiency Cooling load discharge before cooling air flows into the room.
  • spacing profile 49 is on the one hand Attachment of the room temperature control element to the facade support 27, on the other hand a spacing with sufficient space for the air flow A at simultaneous flow direction change - by about 90 ° - guaranteed.
  • the invention is not limited to the exemplary embodiments shown, but rather also includes all embodiments having the same effect in the sense of the invention.
  • other fans are also used come.
  • the use of another suitable heat-exchanging contact element 7 as a lamella register 7 is possible.
  • An embodiment as shown in Fig. 7 could also be inserted vertically into a wall.
  • At a Parallel connection - as shown in Fig. 11 - can also have more than two room temperature control elements to be combined into a block B.
  • the invention is not limited to the combination of features defined in claim 1, but can also be determined by any other combination of certain Characteristics of all of the individual characteristics disclosed can be defined. This means, that basically every single feature of claim 1 is omitted or by at least one individual feature disclosed elsewhere in the application can be replaced. In this respect, claim 1 is only a first attempt at formulation to understand for an invention.
