Definitions

  • the invention relates to a method for ventilating and tempering a provided with a window space, in which an elongated, parallel to and extending in the horizontal direction in front of the window distribution channel supplied via at least one primary air connection primary air and through a large-area outlet cross-section of the distribution channel in the room Supply air is discharged, wherein the primary air is divided into a first partial volume flow and at least a second partial volume flow, and the first partial volume flow of the distribution channel is passed through a first space facing partial outlet cross-section into the room and the second partial volume flow is controlled by a heat exchanger and by a second the part-exit cross-section facing the window is led into the room.
  • the invention also relates to a corresponding device.
  • Such a device is sold for example by the company KRANTZ TKT as so-called Banlauslass for base mounting with integrated heater and is known from DE 44 42 918 A1.
  • the source outlet here serves the supply of air and room heating in the comfort area.
  • the advantages are mainly its compact design, which requires relatively little installation space, and a relatively short assembly time.
  • the Banlauslass is usually arranged in the base area of a window sill.
  • the air connection is generally from below, e.g. via a raised floor or floor duct. In cooling, air is blown out horizontally as well as obliquely and vertically upwards in such a source outlet.
  • the change of the blow-off characteristic is done exclusively by the thermodynamic forces of the cool supply air or by the heated air from the heat exchanger. Movable guiding devices are not required.
  • the described source outlet KRANTZ TKT is not readily suitable for underfloor installation, since the structural design of the source outlet with its lateral outlet cross-section can not be adjusted accordingly.
  • a disadvantage may also be the air blown up vertically, since the insulation is now so high quality in living rooms that the blown up air in cooling does not necessarily after the emergence of the ground, but rather space-centered, and thus in space located persons is made disturbing.
  • the air discharged vertically from the source outlet is sucked in directly by the ceiling extraction, thus generating a disadvantageous short-circuit for the room climate.
  • the object of the invention is to prevent short circuits of air flows between devices for ventilation and temperature control and Deckenabsaugungsvortechnischen even with well-insulated rooms, as well as exclude room-centrally incoming cooling air.
  • An underfloor installation should also be possible.
  • the object of the invention is achieved in a procedural manner in that the entire volume flow is passed in non-active heat exchanger through the first part of the outlet cross-section into the room.
  • the solution is characterized in that the flow through a second sub-channel can be interrupted by means of a shut-off device.
  • the invention can be further developed in that the distribution of the volume flow of the primary air takes place automatically when the heat exchanger is activated.
  • the automatic distribution of the volume flow makes the process particularly easy.
  • the direct coupling to an activity of the heat exchanger requires no measurement and control technology further processing of other parameters, such as temperature in certain parts of the room, etc., and forms a particularly favorable possibility for the control of the distribution of the volume flow.
  • the invention can be configured in that the division of the volume flow of the primary air takes place by means of a shut-off element actuated by a Dehnstoffantrieb, which is activated by the energy supplied by the heat exchanger or dissipated.
  • the Dehnstoffantrieb can be so-called thermoactive wax, thermal wax or the like, and has long been known as a temperature-dependent control element.
  • the drive medium is in its extent dependent on the temperature of the heat exchanger and can accordingly bring the obturator of a closing via intermediate positions in a shut-off, in which no partial volume flow of the volume flow is passed through the first part of the outlet cross-section into the room.
  • One advantage is that there is no wear in such a configuration and thus the inventive method is also suitable for decades of use.
  • the uncomplicated configuration of the drive as a stretch material drive makes the process particularly reliable and absolutely maintenance-free.
  • the second partial volume flow is passed through nozzles on the heat exchanger, can be achieved in a particularly advantageous manner a targeted flow of the heat exchanger at an increased speed and deliver the output from the heat exchanger heat or cold directly to the guided through him on the nozzles air flow.
  • the entire process can thereby take place in particularly compact devices, since the surface of the heat exchanger is covered, without exception, completely by the air passing through the nozzles and the efficiency of the heat exchanger is particularly well utilized.
  • the method according to the invention can also be configured by supplying the first partial volume flow to the space at an angle to the vertical and / or the second partial volume flow to the space in the vertical direction. This is particularly useful in the case of heating, since the second partial volume flow is reheated by the heat exchanger, but the first one is not. If the first partial volume flow is supplied to the space in an oblique direction, turbulences can advantageously be minimized and an increase in the penetration depth of the source air into the room can be achieved, so that an improved room climate with increased comfort also results. Since the second partial volume flow is supplied to the space in the vertical direction, there is also no mutual influence of the two partial volume flows here.
  • the obturator can be z. B. be designed as a rotatably mounted and extending in the longitudinal direction of the distribution channel flap.
  • an advantageous development of the invention is that the obturator of the device automatically from a closed position in which the entire volume flow of the primary air is feasible through the first subchannel, into an open position in which the volume flow of the primary air can be divided, is convertible when the heat exchanger is activated.
  • the division of the primary air into a warm and a cold air flow, which is guided once approximately vertically and once substantially horizontally over the room floor, or the sole horizontal guidance of the air flow in the form of the entire primary air, is a particularly advantageous choice, since the air is performed according to the temperature difference to the room, ie particularly turbulence-free at every election.
  • the vertical or angled orientation of the slats makes it possible to selectively introduce the air into the room at an optimum angle, without having to achieve any special air velocities under which the discharge takes place.
  • the device according to the invention can also be configured in that the expansion material drive, by means of which the obturator can be actuated, is connected in a thermally conductive manner to the heat exchanger.
  • the obturator Due to the expansion of the Dehnstoffantriebs the obturator is opened or closed either directly or by means of an actuating rod from Dehnstoffantrieb, depending on the temperature, if desired, all intermediate positions between the opening and the shut-off of the obturator are ingestible.
  • Such type serve obturator and Dehnstoffantrieb as a switch with which the first part of the outlet cross section for a warm or cold air flow can be opened or closed.
  • the invention will be further developed in that the nozzles are arranged one behind the other in an extending in the longitudinal direction of the distribution channel nozzle plate.
  • the successive arrangement of the nozzles ensures that the primary air introduced via the nozzles is targeted to the heat exchanger, which is also located in the longitudinal direction of the distribution channel, and thus can experience a particularly high heating.
  • a particular embodiment of the obturator should be that this is a rotatably mounted, extending in the longitudinal direction of the distribution channel flap.
  • the invention can be advantageously configured by the obturator is coupled by means of an actuating rod with the Dehnstoffantrieb, wherein the actuating rod is guided through an opening cross-section of a nozzle such that a free residual cross-section remains.
  • This arrangement of nozzle, actuating rod and Dehnstoffantrieb is therefore advantageous because the air introduced through the nozzle avoids prolonged heat storage in the range of Dehnstoffantriebs that distort the mediated by the Dehnstoffantrieb to the obturator position us would lead to a sluggish switching characteristic.
  • a resistance component in particular a perforated plate or fleece, between the primary air connection and the outlet cross section, in particular the first partial outlet cross section is arranged.
  • the device 1 shown in Figure 1 is intended for underfloor installation, in such a way that the device 1 forms with its upper edge 2 'with the floor of a room, not shown, a plane.

  • the entire surface of the outlet cross-section 7 is occupied by a step-resistant grating 8 of vertically aligned slats, which is shown only partially in the figure 1.
  • the first sub-channel 3 has a resistance component 9 in the form of a perforated plate provided with a plurality of equidistant holes and an overlying and the first part-exit cross-section 5 engaging Beerleitstoff 10, which consists of a plurality of lamellae, which are aligned at an angle to the vertical are pointing us to the center of the room.
  • the sub-channels 3, 4 are separated by a channel separation plate 11th
  • a shut-off device 12 in the form of a rotatably mounted and in the longitudinal direction of the distribution channel 1 'extending flap of the sub-channel 4 can be shut off.
  • the obturator 12 is shown in a closed position 14 and an open position 15, wherein the open position 15 is shown in Fig. 1 by a dashed line.
  • the obturator 12 is arranged so that the sealing seam 13 having a side opposite the hinge 16 having a side is pulled down. Thereby, in the open position 15, the penetrating primary air can be conducted by means of the obturator 12 into the second sub-channel 4, without causing any particular turbulence.
  • the second sub-channel 4 has a over the entire length of the device 1 extending heat exchanger 17 with heating tube 18 and fins 19.
  • the actuating rod 21 is guided by a nozzle 22 such that neither in the opening nor in the closed position nor in any of the transition positions, the actuating rod 21 comes into contact with the obturator 12.
  • the nozzle 22 are still more nozzles 23 on a nozzle plate 24, which blocks the partial channel 3 except for the opening cross sections of the nozzles 22, 23.
  • the fins 19 of the heat exchanger 17 also act as an air guide, which direct the air entering through the nozzles 22, 23 in the sub-channel 4 vertically through the partial outlet cross-section 6 upwards.
