Definitions

  • the invention relates to a system for the air conditioning of rooms, consisting of a heating / cooling unit, distribution pipes and discharge units.
  • the optimal value for the temperature and / or humidity of the supplied, conditioned air is from room to room Space different.
  • the invention has for its object to provide a system for air conditioning of rooms, which has maximum flexibility in terms of its Adaptation to the respective existing requirements in the air-conditioned rooms and in individual areas of the same. Despite the high flexibility, the air conditioning system should be inexpensive to manufacture and easy to set up or arrange for maintenance.
  • the system is modular, that it has a maximum vertical extension of 22 cm, which allows the installation of the system in a suspended ceiling, and that the flow of conditioned air through each outlet unit is individually adjustable .
  • the air conditioning system according to the invention thus combines all the features that are important for an advantageous high degree of flexibility in use: the modular design of the air conditioning system according to the invention means that the production costs can be reduced to such an extent that the installation of one heating / cooling unit per room is included reasonable cost is possible, whereby the condition of the air supplied can be selected individually for each room.
  • the arrangement of the entire system in the suspended ceiling prevents the use of other usable space.
  • the distribution pipes can be made particularly short.
  • the modular structure of the invention Systems, its individual parts can be combined with one another as required. This is particularly advantageous in connection with the design of the system, which allows it to be installed in a suspended ceiling. In this way, the individual parts of the air conditioning system are accessible at all times and can therefore also be adapted to changing requirements at any time. For example, when changing the use of the room (e.g. equipping with heat-emitting machines) or changing the room layout (e.g. moving the partition walls in an open-plan office), the previous heating / cooling unit can easily be replaced with one with a different output.
  • the modular structure also allows the air conditioning system to be manufactured at a relatively low cost because of the large-scale production involved, so that the air conditioning system according to the invention is competitive with conventional central systems.
  • the outflow units By designing the outflow units in such a way that the air throughput through each of them can be individually adjusted, different areas of a room can be supplied with different amounts of conditioned air according to the respective requirements.
  • the outflow units each have a pair of pivotable flaps which, depending on their position, release a more or less large flow cross section.
  • the flaps are articulated with their outer longitudinal edges on supports and their inner longitudinal edges cooperate with at least one link, which can be moved vertically, whereby the flaps are opened or closed.
  • the air supply can be adjusted individually at each individual workstation within the room; furthermore, the total flow conditions within the air-conditioned room can be influenced with a suitable setting of the flow through the individual outflow units.
  • the vertical position of the link can be adjusted by means of a regulating screw accessible from below.
  • a regulating screw accessible from below.
  • Nylon can be used as an advantageous material for the backdrop and the regulating screw.
  • the flaps have projections on at least one end face in extension of the inner longitudinal edges, which engage in the - at least one - link.
  • the outer longitudinal edges of the flaps advantageously have a bead with a circular cross section, which cooperates with a correspondingly shaped recess in the outlets of the outflow units in a hinge-like manner.
  • a perforated plate can be arranged above the flaps between the supports, which serves to even out the flow over the entire length of the outflow unit. Otherwise, a stronger and / or more uneven flow through the outflow unit can possibly occur in the vicinity of the junction of the distribution pipes in the outflow units than in the areas away from the distribution pipes.
  • the outflow units expediently have devices which ensure that the flow of the exiting conditioned air is not directed vertically but at an angle downwards.
  • a device advantageously consists of a diffuser which has a plurality of flow channels separated by baffles, the outlets of which are directed obliquely downward into the room to be air-conditioned.
  • a diffuser preferably has two groups of three flow channels, through which the air is blown out obliquely in two different directions. This considerably reduces the risk of "drafts" occurring.
  • the inclination of the oblique air outlet direction to the vertical is preferably about 45 ° to 60 ° C.
  • connection of the diffuser to the supports is advantageously carried out by means of intermeshing guides, because this type of connection permits particularly problem-free installation.
  • a particularly suitable material for the manufacture of the diffusers is denilen (registered trademark of Deniplast).
  • a maximum adaptation of the air conditioning system to the local requirements is possible in that the direction of the outflow of air from the outflow units can be influenced and individually adjusted.
  • This setting of the outflow direction is advantageously carried out by a horizontally pivotable partition which is arranged in a downward outflow slot of the outflow unit.
  • the outflow direction can be set in a simple manner, as can the flow rate; with a suitable shape of the partition and / or the outflow slot, no tools are required for this either.
  • the partition preferably has an approximately triangular, downwardly widening flow deflector at its lower end.
  • the greatest width of the flow deflector is almost equal to the clear width of the outflow slot.
  • the horizontal pivotability of the partition can preferably be achieved in that the partition has at its upper edge at least two arcuate fork elements which are received in a trough which has the outflow slot and forms the lower end of the outflow unit; for this purpose the trough suitably has an arcuate cross-sectional shape adapted to the fork elements.
  • the fork elements and the areas of the trough interacting with them preferably have a tooth-shaped latching mechanism, which holds the partition securely in the set position. This prevents unintentional adjustment of the position of the partition, for example by flow effects.
  • the trough and the supports are also preferably connected to one another by means of interlocking guides in order to simplify assembly.
  • a preferred material for the manufacture of the carrier and flaps as well as the trough and the partition is flame retardant ABS plastic because of its good workability.
  • the heating / cooling unit of the air conditioning system has a heating battery and a cooling battery, which are preferably arranged one behind the other in the direction of flow. In this way, a particularly flat overall height of the heating / cooling unit can be achieved, which gives the possibility of in installation in a suspended ceiling favors. Due to the arrangement of the cooling battery in the flow direction upstream of the heating battery, the heating / cooling unit can also be used to dehumidify the ambient air that is drawn in, by first cooling the ambient air below the saturation temperature with the aid of the cooling unit, whereby the moisture contained condenses out; the dehumidified air is then heated to the desired temperature using the heating battery.
  • the air flow is advantageously controlled by means of two two-way control flaps, which each reduce the flow cross section of the respective bypass channel to the extent that they release the flow cross section through the cooling or heating battery.
  • the two-way control flaps can - depending on the desired condition (temperature and / or humidity) of the air entering the room - be controlled so that the air through the cooling battery, through the Heating battery or both batteries flows or is bypassed by both batteries.
  • a filter plate for removing particulate air pollution is advantageously installed in the heating / cooling unit for cleaning the sucked-in air.
  • the filter plate can be removed from the bottom in the heating / cooling unit, so that the exchange of a loaded filter plate for a regenerated filter plate is very simple.
  • a lamp for irradiating the air flowing through with UV light can also be arranged in the heating / cooling unit in order to kill germs contained in the air flowing through.
  • FIG. 1 shows the air conditioning system consisting of a heating / cooling unit 1, a distribution pipe 2 and an outflow unit 3, which is installed above a suspended ceiling 4.
  • the heating / cooling unit 1 has a blower 5 in the form of a roller fan, which sucks in the unclimated ambient air through an intake line 6. Between the intake line 6 and the blower 5, the intake air passes through a filter 7 and is irradiated with ultraviolet light from a UV lamp 8.
  • the filter 7 is formed by a filter plate, which can be removed downwards for replacement (arrow A) from the housing 9 of the heating / cooling unit 1.
  • a cooling battery 10 and a heating battery 11 are arranged in the heating / cooling unit 1; the cooling and heating batteries 10, 11 have a vertical extent which corresponds to approximately half the value of the height H of the heating / cooling unit 1; in this way, bypass channels 12 are formed in the interior of the heating / cooling unit 1 parallel to the cooling or heating battery.
  • Two two-way control flaps 13, 14 pivotable about horizontal axes serve to adjust the flow through the cooling battery 10, the heating battery 11 and the bypass channels 12. In the case of the position of the two-way control flaps 13, 14 according to FIG the air bypasses the cooling battery 10 through the bypass channel 12 and then flows through the heating battery 11.
  • the conditioned air is supplied to the outflow unit 3 through the distribution pipe 2.
  • a pair of flaps 17 is arranged so that they can be pivoted about their outer longitudinal edge 18.
  • the inner longitudinal edges 19 have projections 20 which are guided in a link 21.
  • the flaps 17 are closed or opened by vertical displacement of the link 21 (arrows B, C). In this way, the amount of air emerging through the outflow unit 3 is adjusted.
  • a channel 22 has an insulating coating 23 on its inside and has a connection piece 24 for connection to the distribution pipe 2 according to FIG. 1.
  • the channel 22 is U-shaped and is provided on its lower longitudinal edges 25 by means of interlocking guides 26, 27 with two Carriers 28, 29 connected.
  • the carriers 28, 29 have recesses 30 in their longitudinal direction which describe approximately two thirds of an arc of a circle.
  • the flaps 17 have on their outer longitudinal edges 18 beads 31 with a circular cross-section such that the beads 31 cooperate with the recesses 30 in the supports in a hinge-like manner.
  • the setting 21 can be adjusted in its vertical position by means of a regulating screw 32, the regulating screw 32 being fixed in the axial direction.
  • the regulating screw 32 is axially fixed by means of a bearing (not shown) in the diffuser 33, which cooperates with the bearing section 34 of the regulating screw 32, which is delimited by the head 35 and a collar 36 of the screw.
  • the diffuser 33 is connected to the carriers 28, 29 by means of interlocking guides 37, 38.
  • the diffuser 33 has baffles 39 through which Flow channels 40 are limited. By angling the guide plates 39 in their lower regions, the flow channels are inclined in their lower section, which results in an outward flow of air.
  • a perforated plate 41 is arranged between the carriers 28, 29, which brings about an equalization of the emerging air flow.
  • the perforated plate 41 is also connected to the supports by means of interlocking guides.
  • the panels 42 of the suspended ceiling have openings 43 which extend transversely to the longitudinal direction of the panel and through which the air emerging from the outflow units enters the room.
  • the diffuser 33 according to FIG. 2 is replaced by a device which enables the outflow direction to be influenced.
  • This device is formed from a trough 44 which has an outflow slot 45 in its longitudinal extent.
  • the Outflow slot 45 is formed by two parallel walls 46 of the trough 44 in its lower section. In its upper section, the trough 44 has concavely curved walls 47 which have guides 48 on their upper edges for connection to the supports 28, 29.
  • a partition 49 which has fork elements 50 on its upper edge.
  • the fork elements 50 have a curvature which corresponds essentially to that of the concavely curved walls 47 of the trough 44, so that the fork elements 50 rest in the trough 44, but they can be pivoted with respect to the longitudinal axis of the trough. In this way, the position of the partition 49 within the outflow slot 45 can be influenced.
  • a triangular, downwardly widening flow deflector 51 on the lower edge of the partition 49 provides for a deflection of the air emerging from the outflow slot 45 in a direction inclined to the vertical.
  • the regulating screw 32 is included their bearing section 34 axially held in a (not shown) bearing in the trough 44.
  • the parallel walls 46 delimiting the outflow slot 45 are arranged between two diaphragms 42 of the suspended ceiling, so that the diaphragms can be designed without openings.
  • the outflow unit according to FIG. 3 corresponds to that according to FIG. 2, so that the corresponding explanations for FIG. 2 also apply to the embodiment according to FIG. 3.
