The invention relates to a Raumtemperierungselement consisting of

• at least one heat transfer profile, which is designed in particular in the form of a pole or bolt to be fastened in an interior and encloses with its wall a cavity which is designed as an air duct and has at least one air inlet opening and at least one air outlet opening,
• at least one duct running within the cavity in the longitudinal direction of the profile and permeable by a temperature control medium,
• at least one of the heat exchange with the air serving contact element which has a predetermined length, width and depth and is thermally conductively connected to the duct, and
• at least one fan for generating a forced convection in the air duct.

Furthermore, the invention relates to an arrangement of such a Raumtemperierungselementes.

To cover the heat demand of rooms or a cooling load from a room dissipate, can be achieved with various types of heat transfer elements become. So has a heat transfer over radiation surfaces the advantage of only one very low air movement, which, however, with disadvantageously necessary large active Heat transfer surfaces must be bought. Such large-area heat transfer surfaces disturb the optical transparency especially on facades. Furthermore can thermal load changes in heat transfer systems with radiation preference time only very delayed to come into effect, for example the fabrics of clothing of persons represent heat transfer resistance, which react slowly in preferred radiant heat transfer. In the case of cooling are the Transmittable thermal power in radiation systems for heat exchange often too low.

A heat supply or removal for an interior can also be convective with air as flowing medium can be achieved. Purely convective systems have to be larger Circulate air volumes to a comparable with radiation and Konvektionskombinationen Transfer power.

German utility model DE 201 06 951 U1 describes a room temperature control element of the aforementioned type. This known Raumtemperierungselement consists of at least one heat transfer profile, the heat transfer profile is formed in the form of a hollow support or a hollow bolt, and with its wall encloses a profile extending in the longitudinal direction cavity. Within the cavity extends in the profile longitudinal direction of a Tempering medium permeable duct. The cavity is as Air duct formed and has at least one air inlet opening and at least one offset in the flow direction arranged air outlet opening on. The duct is thermally conductive with at least one contact element connected, which in turn connected to the wall of the heat transfer profile thermally conductively connected. On the wall inside the cavity are to increase the thermal effective inner wall surface in the Cavity protruding contact profiles formed. To create a forced Convection can be a fan in the area of the air inlet and / or outlet be provided. With this known Raumtemperierungselement can overcome the aforementioned disadvantages. However, there is a limit of transportable through the Temperierungselement air volume flow in Profile inside through the profile cross-section, for example, on a facade aligns. Also, the heat transfer profile must have a certain minimum length have enough power to transfer to the air flowing through.

The invention is based on the object, a Raumtemperierungselement the to create the aforementioned type, the compact design and universal possibility its arrangement in building interiors, e.g. in the area of a facade, has a high efficiency and high reliability.

According to the invention, this object is achieved in that over the length of the contact element a plurality of fans are arranged, each having an effective flow area have, whose width is about the same size as the width of Contact element, and which have a maximum distance from each other, the approximately is four times a length of the effective flow cross-section of the fan.

The invention thus preferably relates to the heat transfer mechanism by means of forced convection, whereby by a series of fans along the contact profile, in particular a fin heat exchanger, a substantially rod-shaped Raumtemperierelement arises. In the simplest case, the air flow can without diverting from the suction by means of the fan through the one Slat register and the channel through which temperature control medium can flow made lamellar heat exchanger into the room into it. The total pressure loss is very small.

As a fan commercially available micro fans, in a preferred embodiment, in particular axial fans, used and operated at half speed, which makes the system very quiet. The air becomes so to speak "segmental" compressed over the micro fans, when flowing through the contact element tempered (heated or cooled) and supplied to the room. A through the Heat exchanger fins effected only very small flow pressure loss allows Single fan powers of less than 20 W, and preferably of less than or equal to 1 W, in particular in the case of an immediate oncoming flow of the heat exchanger fins Through the fan high air turbulence can be generated. Especially in the inlet part the heat exchanger fins thus provide very high heat transfer rates a, and - based on the heat exchanger dimensions - are very high thermal Services transferable.

The space temperature element according to the invention can be advantageously without Arrange difficulties arbitrarily in a room, e.g. on a facade, on one Wall, ceiling, parapet, etc. Another advantage is that at one minimum distance between the fans and the contact element for the invention Room tempering element as a whole a high function redundancy, i. Operational safety, can be achieved, since in case of failure of a fan only the only associated segment of the contact element has a performance-reducing effect and no failure the entire device occurs.

As in the room temperature control element according to the invention necessarily neither Flow deflections still constrictions are present and thus smooth Penetrations exist, with the fans in the air transport a high turbulence cause hardly any risk of contamination at comparatively low pressure loss and it can be deliberately omitted filtering the air. A Bacterial accumulation in a filter and associated hygienic disadvantages can not come up like this.

By juxtaposing a certain number of fans is the air power and thus the thermal bar capacity linear over the length of the invention Room tempering element determinable. Should due to the required thermal Performance only a few fans will be necessary, so that they are not flush with the housing, but spaced from each other, so the fans can also from Move the air inlet area in the contact element, so that the fan no longer almost gap-free in front of the contact element, in particular in front of the slat register, are arranged. As a result, before the contact element, a pressure compensation chamber or formed a vortex chamber. An air admission of the contact element, in particular the heat exchanger fins, thus takes place in places where no Fans are directly upstream. The distance fan / slat entry can be especially with the aim of setting a maximum air turbulence at the slat entry varies and depends on the length of the invention Room tempering element related number of fans.

The room temperature control element according to the invention advantageously also allows an external air supply and thus a simultaneous temperature control of outdoor and recirculated air in one and the same device. Air deaeration or humidification can also be beneficial take place within the Raumtemperierungselementes invention.

Further advantageous embodiments of the invention are in the dependent claims and the included in the following specific description.

With reference to several embodiments shown in the accompanying drawings the invention will be explained in more detail.

Cross-sectional views of room temperature control elements according to the invention in various other mounting arrangements according to the invention.

In the various figures of the drawing, the same parts are always with the the same reference numerals, so that they usually only once to be discribed.

As initially shown in FIGS. 1 and 2, there is an inventive Raumtemperierungselement from at least one heat transfer profile 1, which in particular in the form of a pole or bolt to be fastened in an interior is and surrounds with its wall 2 a cavity 3, which serves as an air duct is formed and at least one air inlet opening 4 and at least one Having air outlet opening 5 for room air.

Furthermore, the room temperature control element according to the invention consists of at least a within the cavity 3 in the profile longitudinal direction X-X (Fig. 2) extending, from a temperature control medium, in particular water, through-flow conduit 6 and at least one heat exchange with the air serving contact element 7, which is designed as a lamellar register and a predetermined Length L7, width B7 and depth T7 and with the duct 6 thermally conductive connected is. The slat register fills the air duct with its width B7 completely in terms of its width.

Finally, the room temperature control element according to the invention consists of several Fans 8 for generating a forced convection in the air duct. The air flow directions are with the arrows Z as air flow to Raumtemperierungselement and A marked as corresponding airflow.

The air flows as in Fig. 1 for a first embodiment and in Fig. 2 for a second Embodiment of the invention is shown, in particular by a grille 9 for the Air inlet 4, is compressed by means of the fan 8 and passes according to the first Execution in a pressure equalization chamber downstream of the fans 8 in the flow direction or in a vortex chamber 10. In the second embodiment is no provided such chamber, that is, that the fan 8 almost gap-free before the Contact element / lamella register 7, are arranged.

According to the invention over the length L7 of the contact element 7 more fans. 8 arranged. These fans 8 have an effective flow cross-section, whose Width B8, as shown in FIG. 1, is about the same size as the width B7 of the contact element 7, and which have a maximum distance A8 (see Figures 4 and 8) from each other can be up to about four times a length L8 (FIG Flow cross-section of the fan 8 may be. According to the one shown in FIG However, this distance A8 is zero, i. the fans 8 are flush with the housing arranged to each other.

The heat transfer profile 1, as shown in FIG. 2, in particular rod-like be formed, wherein a length L1 (Fig. 2) of the heat transfer profile 1 in a ratio to a width B1 (FIG. 1) of the heat transfer profile 1 of FIG at least 2: 1, preferably at least 10: 1. By mounting a specific Fan number is - as already mentioned - the air flow and thus the thermal rod power linear over the length L1 fixable.

The air flows from the fans 8, in particular with a high degree of turbulence, in the lamellar heat exchanger formed from the lamellar register 7 and the duct 6 6/7, is tempered when flowing through the slats 7a and the room through a cover grille 11 for the air outlet opening 5 again fed (arrow A). The extending between the slats 7a in the slat register 7 formed air gaps 7b between the air inlet opening 4 and the air outlet opening. 5 straight in profile transverse direction and in particular axially parallel to the center axis Y-Y preferably designed as an axial fan fan 8. As a result, the flow resistance the air gaps 7b and thus the occurring pressure loss of the air low held.

In Fig. 1 are two in the longitudinal direction X-X (Fig. 2) of the Raumtemperierungselementes extending lines 6, 12 shown. On the one hand, this is the duct 6, which is a water-bearing flow pipe, and on the other hand, a return passage 12 for the Water. The arrangement of these two water-carrying pipes 6, 12 - flow and Return - is chosen so that between the flowing air and the water one the greatest possible temperature difference exists. Especially when using a Raumtemperierungselementes invention simplified as vertical supports Thus, the room temperature control considerably compared to known technical Solutions. By a suitable control device can be an outside temperature-dependent water-side central pre-regulation done, and the fan 8 can alone by their connection and disconnection, in particular in all embodiments of the invention can also be customized, take over the setting of the room temperature.

The fans 8 can, as shown particularly in FIG. 1, mounted on a mounting plate 13 be, as part of the wall 2 of the heat transfer profile 1 in places without fan 8 forms a room-side conclusion. The mounting plate 13 is in the shown representation of a guide rail 14 to particular plate-like Side walls 15 of the wall 2 of the heat transfer profile 1 attached. These Fan mounting is very easy to install, since the mounting plate 13 is equipped separately and then assembled as a whole. Insulating elements 16 separate the Contact element 7 heat-insulating of the plate-like side walls 15. This Insulating elements 16 not only prevent the heat flow through the wall 2 of the Heat transfer profiles 1 to the environment, but also assume a sound insulation function.

The fans 8 may be in particular small or micro fan, the a power consumption of preferably less than 20 W, more preferably of less than or equal to 1 W, exhibit. Small or micro fan also means that the Width B8 and the length L8 of the effective flow area of each fan 8 each maximum about 300 mm, preferably at most about 50 to 80 mm.

It is assumed that the width B8 and the length L8 of the effective Flow cross-section of each fan 8 each minimally by the size of the Diameter D8 of a fan 8a of the fan 8 and a maximum about by the Size of the width GB8 (shown only in FIG. 1) or the length GL8 (only in FIG. 2) shown) of a housing 8b of the fan 8, optionally plus one up to 15 Percentage of this size GB8, GL8 mounting distance MA8 to be considered (only in Fig. 1) for the respective fan 8, is fixed.

Each fan 8 should in each case generate a maximum volume flow of about 0.5 m ³ min ^-1 , preferably of about 0.1 m ³ min ^-1 .

As already mentioned, in the first embodiment of the invention (FIG. 1), the fans 8 are downstream of the air a vortex chamber 10 in the inflow direction. This is also true Further embodiments of the invention to (Fig. 3, 4, 7, 8). The depth T10 of the Vortex chamber 10, d. H. the distance fan 8 - slat input depends on the Number of single fans 8 relative to rod length L1. With the increase of this Number of fans is a reduction of the distance fan - slat input (Whirl chamber depth T10).

Due to a deliberate, high turbulence in the vortex chamber 10 and in the Slat register 7 is formed in the cooling case, a cooling performance maximizing sub-cooling effect with dew point shift, so that the heat exchanger fins 7a under the nominal dew point of the air can be operated, thus increasing the cooling capacity becomes. Conversely, in the case of heating, the heating power is generated by high turbulence maximizing effect.

An additional option of Raumtemperierungselementes invention provides an outdoor air connection 17 (FIG. 3). During the room temperature control element according to the second embodiment of the invention be referred to as a "pure convection bar" is, is for the third, fourth and seventh embodiments of the invention (Fig. 3, 4, 8) such an outside air connection 17 is shown. In rooms with outside air requirement can thus also the outside air supply via the room temperature control elements according to the invention respectively. The formed as a separate unit outdoor air connection 17 can - as shown - an outside air filter 18, and an outside air fan 19 with Outdoor air duct feed 20 include. The outside air connection 17 may be, for example with advantage for a room temperature element or as a unit for several Tempering z. B. housed in a parapet.

The heat transfer profile 1 can be used to guide outdoor air AL and their summer pre-cooling or winter preheating a first, on one Inflow the contact element 7 fluid upstream upstream inflow 21 to the outside air distribution, on a downstream side of a contact element. 7 fluidly downstream deflection chamber 22, from which a return flow of the Outside air AL to the inflow side, as well as on the inflow side, preferably with vortex chambers 10 formed between the fans 8 and the contact element 7 in associated, outflow chamber 23, wherein in the outflow chamber FIG. 23 shows a mixture of the outside air AL with the room air drawn in by the fans 8 (Arrow Z) takes place.

In the embodiments with supply of outside air AL is - as in the second Embodiment of the invention - the finned heat exchanger 6/7 as a single pipe element only with the water-bearing flow 6 shown.

The fourth embodiment of the invention (Figure 4) differs from the third Embodiment of the invention (Fig. 3) in that the fans 8 from each other are spaced apart (distance A8). Such a design also shows that Seventh embodiment of the invention (Fig. 8). To serve the spacing Ventilordistanzanzstücke 24, which are arranged between the fans 8.

The number of fans 8 is determined by the required thermal performance the room temperature control element according to the invention. For a given number of fans 8 should be carried out to optimize the distances A8. With this Distance optimization can be pursued in particular the goal, a high To achieve turbulence at the lamellar inlet, but also other geometric and the operating condition characterizing boundary conditions are observed.

From this point of view, it is particularly extremely advantageous if the Fan 8 generate such a volume flow, so spaced from each other (Distance A8) and spaced from the fin register 7 (distance T10) arranged are and / or the geometry of the air gaps 7b between the slats 7a selected such is that in the air gaps 7b over at least a quarter, preferably at least over a third, their depth T7 between the air inlet opening 4 and the air outlet opening 5, a flow is formed by Reynolds numbers Re in the range of over 2500, preferably of over 5000, is characterized.

The Reynolds number Re represents a variable characterizing the flow state of a fluid. It is assumed that at a Reynolds number Re of less than about 2300 there is a purely laminar flow, and then at a value of greater than 2300 a transitional region between laminar flow and flow turbulent flow and finally an area of pure turbulent flow. The Reynolds number is calculated according to the formula re = w * 1 v where w is the flow velocity of the fluid (in m / s), v is the kinematic viscosity of the fluid (in m ² / s) and l is a characteristic length (in m) of the flow channel. For a circular cross section of the flow channel, the characteristic length l is equal to the diameter of the channel. For non-circular cross-sections - as in the present case of the lamellar register 7 - the characteristic length l results l = 4 * F U where F is the area and U is the circumference of the cross-section of the flow channel. For an air gap 7b in the lamellar register 7, therefore, the characteristic length l results l = 2 * B7 * W7 B7 + W7 wherein B7 - as already stated - the width of the louver register 7 and the lamella 7a and W7, the gap width of the gap 7b between two lamellae 7a.

As a result of such optimizations, it has been found that the preferably usable, with regard to their main characteristics, such as dimensions and flow rate, already specified fan 8 then an optimal distance A8 from each other, if its size is minimized by a flush with the housing Arrangement of the fan 8 and a maximum of about the size of the length L8 of the effective Flow cross-section of the fan 8 is limited.

The air gaps 7b formed between the slats 7a in the slat register 7 can optimally have a gap width W7 of about 2 mm to 15 mm. The distance W7 between the heat exchanger fins 7a also follows an optimization at to be considered as opposite tendencies, the distance W7 in the sense of a minimum pressure loss across the depth T7 of the slats 7a as large as possible, in the sense However, a maximum heat transfer capacity of the louver register 7 should be chosen as small as possible (as many slats 7a).

As numerical values for a maximum distance T10 (depth of the vortex chamber 10) the fan 8 of the fin register 7 are about 10 cm, preferably about 2 cm, considered.

The fifth embodiment of the invention shown in Figs. 5 and 6 shows an inventive Room tempering element, for wall or facade mounting Mounting bracket 25 are provided. At the same time in Fig. 5 is an electrical connection 26 for the fan 8 shown. The heat transfer profile 1 is with its transverse axis (This corresponds in their direction of the center axis Y-Y of the axial fan trained fan 8) arranged at right angles to the wall or facade level, wherein the air inlet opening 4 facing the wall or facade. This also goes from the Sectional view in Fig. 6 shows the arrangement of the room temperature control element according to the invention on a facade support 27 shows. Between facade support 27 and Raumtemperierungselement is doing an air space 28 through which the from an optional glazing 29 or facade construction influenced air flow can be sucked off and tempered.

The element arrangement is not limited to vertical supports. Horizontal bars are as conceivable as an arrangement in the ceiling, as for the sixth Embodiment of the Invention FIG. 7 is shown. The advantage of a invention Raumtemperierungselementes consists in a ceiling arrangement in a very low required height and the possible concentration on small areas or stripes. In this, as a finished element, in particular as a grid element, formed, for a ceiling installation suitable embodiment of the invention Raumtemperierungselementes is one of the plate-like side walls 15 to a horizontally in a ceiling cavity 30 a lying upper foreclosure of Room tempering element converted. The air inflow Z, e.g. as warm Room air is carried out by a lower screen element 31, which has a high degree of perforation and both have the function of one in the other embodiments plate-like side wall 15 and the functions of the grille 9, 11 for the Air inlet opening 4 and outlet opening 5 takes over, in a Deckenanströmkammer 32. From there, the compaction and promotion of indoor air is again in the above described manner with a selected according to the power requirement Number of consecutive fans 8. After e.g. a cooling of the air in the Slat register 7 and a deflection in a Deckenabströmkammer 33 completes the outflow A of the cooled air through the lower screen element 31st back in the room. A plate-like side boundary 34 secures the Lamellenzwangsdurchströmung and is advantageous to a ceiling element 30b fixable.

In Fig. 8 is an embodiment of a Raumtemperierungselementes invention shown, in contrast to the other remarks between the Slats 7a formed in the slat register 7 air gaps 7b between the air inlet opening 4 and the air outlet opening 5 obliquely to the profile transverse direction (turn characterized by the course of the center axis Y-Y of the trained as axial fan Fan 8) extend.

As a result of the inclination of the slats 7a is formed in the cavity 3 a Schachtwirkung, which in analogy to a convector by convection in the heating and Cooling case power can be transferred. In case of heating and with vertical supports thus heat without the use of the fan 8 transferable. One also in Fig. 8 shown, located in the cavity 3 under the fin register 7 condensate tray 35 can by cooling humid air, especially outdoor air AL accumulating Take up condensation, which then via a condensate drain connection 36th can be derived.

By additional introduction of an air humidifier, such as a Humidifying lance 37, in the outflow chamber 23 of the cavity 3 is also a Humidification in case of too dry winter outside air AL possible. The control of Humidifier performance can take place by means of the solenoid valve 38.

In the case of the further embodiment of a room temperature control element according to the invention shown in FIG it is an arrangement in which the fan 8 between two in the axial direction Y-Y of the fan 8 successive lamellae 7 are mounted. A lamellae register 7 is with the in the cavity 3 as Advance trained duct 6, the other with the trained as a return Conduit 12 structurally combined to each a finned heat exchanger 6/7, 12/7. Compared to the arrangement of FIG. 1, the fans 8 have a in this embodiment increased mechanical protection, since they are embedded in the lamellar register 7. There also side of the slat register 7 insulation elements 16 are arranged, is also ensures a highly effective soundproofing. Compared with Fig. 6 occurs in the in Fig. 9 variant thus a significant noise reduction. The protected arrangement of the fan 8 also allows a very light, elastic and thus structure-borne noise-insulated suspension of the fan 8 on the side walls 15 of the Heat transfer profile 1, which contributes to a further noise reduction.

In a parallel arrangement of two in the flow direction of the air in a row lying slat register 7 or fin heat exchanger is also advantageous a separate supply of registers with cooling or heating water feasible. For one Such supply can both pipes located in the cavity 3 as a flow be formed, which in Fig. 9 by the parenthesized reference numeral 6th is indicated. In the presence of two fin heat exchangers 6/7 can at horizontal arrangement of the room temperature control element of the upper fin heat exchanger 6/7 for heating and the lower finned heat exchanger 6/7 for cooling be used. In this case, then in the sense of further increase the Cooling capacity of the lower finned heat exchanger 6/7 with water temperatures below be operated at the dew point and the condensation over a condensate water tank 35, as shown in Fig. 8, are collected and derived.

If it should be provided that - as mentioned above - the temperature of the Conduit 6 flowing through Temperierungsmediums, in particular in dependence is set from an outside temperature, so can advantageously below Use of the embodiment of the invention shown in Fig. 9 when using a Vierleiteranordnung two changeover valves can be saved.

Similar to the first embodiment of the invention (Fig. 1) is in the in Fig. 9 illustrated embodiment the fans 8 in the flow direction of the air a vortex chamber 10 downstream, which has the depth T10. A similar chamber 10a with the depth T11, d. H. Distance slat exit - fan 8, in this version is the Fans 8 upstream. Also in this chamber 10a can Luftverwirbelung and a pressure equalization take place, and with the increase in the number of individual fans. 8 Based on the rod length L1, a reduction of the depth T11 can be provided become.

The embodiment shown in Fig. 10 of a Raumtemperierungselements invention has in extension to the embodiment in Fig. 6, two heating / cooling elements, which are inserted in an intermediate wall 39 with facade connection. The facade connection the intermediate wall 39 is a on the facade support 27th attached longitudinally to this extending facade connection plate 41 realized. The arrangement of the room temperature control elements is chosen such that the heat transfer profile 1 is fixed in each case in a wall cavity 39a. It is the formed as a rear wall side wall 15, which - similar to the embodiment according to Fig. 7 - the cover grids 9, 11 opposite and with these on the side boundaries 34 is connected to be designated as a partition wall transition piece Wall element 40 attached. The partition transition piece has a compared to the thickness D39 of the wall 39 reduced thickness D40 and is in vertical Oriented towards the facade connection plate 41, so that thereby the wall cavities 39a formed by the heat transfer profiles 1 with flush termination be filled to the partition 39.

Also in analogy to the room temperature control element according to FIG. 7 is in the respective heat transfer profile 1 in the flow direction in front of the fans 8 a Wandanströmkammer 32 a and in the flow direction behind the contact element 7 a Wandabströmkammer 33 a formed. As in the Deckenanströmkammer 32 and the Deckenabströmkammer 33 takes place in the Wandanströmkammer 32 a and in Wandabströmkammer 33a a flow direction change of the air, in particular a Change of direction by 90 °.

Using the illustrated arrangement is also a prevention or Reduction of sound transmission from the room on one side of the partition wall 39 achievable to the room on the other side. Additionally, you can - as shown - Also insulating elements 16 on the wall element 40 (partition wall transition piece) be applied, with which the sound reduction is enhanced. As room tempering element can also be the embodiment of FIG. 9 are used.

In the example of installation according to FIG. 11, there are two schematized Raumtemperierungselemente the type of FIG. 9 in parallel at a distance to a Outside wall 42 shown. Due to the parallel arrangement of the with their side walls 15th abutting heat transfer profiles 1 form the room temperature control elements a common block B with increased power. A parallel to the Outside wall 42 or to a window (glazing 29) moving exhaust air flow AS the room air can by the spaced arrangement to the outer wall 42 between Outside wall 42 and windows and Raumtemperierungselement fall down and from the Room tempering elements sucked from below and then heated as air outflow A from Temperierungselement or as air inflow with respect to the Space be supplied to the room. In addition - as shown - under the room tempering elements if required, external air AL can be supplied. Via an outside air grille 44 and an adjustable outside air damper 43, and - as already with reference to FIG. 8 described - the outside air filter 18 and the outside air fan 19, the can in the winter cold outside air flow AL before entering the room temperature control with the sucked indoor air (exhaust air flow AS) are mixed before the air after the Temperature control is returned to the room. In summer, the process is analogous for cooling. An additional dew point sensor prevents condensation. By the reference numeral 45 is a building ceiling and by the reference numeral 46 denotes a room-side inflow grating. Through the room-side, the outer wall 42 facing away, in the longitudinal direction of the heat transfer profile 1 in front of the room temperature control elements arranged inflow grid 46 passes another air flow Z to the room temperature elements, which is before entering the air with the Can mix exhaust air flow AS and the outside air flow AL. Through the illustrated Arrangement is thus at one through the building ceiling 45 and the outer wall 42nd formed space edge a space chamber R formed by the outer wall 42, the Building ceiling 45, the inflow grille 46 and the Raumtempenerungselement limited is. A gap between the heat transfer profile 1 of the Raumtemperierungselementes and the outer wall 42 forms a flow channel K for the Exhaust air flow AS and an inflow channel to the space chamber R. Der Flow channel K can also be provided with a wall-side inflow grating 46a be, with this Zuströmgitter 46a and the room-side Zuströmgitter 46 also for Attach the wall transfer profile 1 can serve.

FIGS. 12 and 13 show variants of the arrangement of the room temperature control elements according to the invention in floor double-floor cavities. Also in these representations the room tempering elements are shown schematically. The raised floor is designated by the reference numeral 47. He has a wall-side bend 47 a, which is supported on the building ceiling 45, whereby a bottom cavity 48 is formed, each receiving the Raumtemperierungselement, in both Figures according to the design of FIG. 9 is executed.
