Definitions

  • the invention relates to a device for air conditioning of rooms according to the preamble of claim 1 or 9.
  • Devices of the type discussed here are used for decentralized heating or cooling of rooms.
  • the devices also serve for ventilation, by outdoor air or circulating air.
  • the devices can work on ventilation with outside air and recirculating air or with either outside air or circulating air.
  • the decentralized arrangement of such devices is preferably carried out in the floor or ceiling area.
  • Each room has at least one device.
  • Efforts are made to keep such devices as compact as possible, so that they only need a relatively small section in the floor or in the ceiling, which is covered by a single or multi-part grid.
  • Especially those devices that fulfill several air conditioning tasks and thus are universally applicable have several individual components that need appropriate space, especially when the device is placed in the bottom area where it must be accommodated in a relatively shallow space.
  • the extension or retrofitting of existing devices is difficult because of the additional components of the air conditioning device space must be created, which makes additional cutouts in the false floor or in the ceiling panel necessary.
  • the invention has for its object to provide a device for air conditioning of rooms, which manages with a relatively small section in the false floor or in the ceiling panel, is easily expandable and easy to assemble and service.
  • the secondary housing accessible through a secondary opening in the housing provides additional space for further components of the air-conditioning device which can not be accommodated in the housing.
  • the sub-housing does not require its own cutout in the floor or in the ceiling, because it is accessible through the opening serving as a passage opening from the housing. It can be equipped with additional components of the air conditioning device so the sub-housing by the coverable by at least one grid opening of the housing and a passage to the sub-housing creating secondary opening. This facilitates the assembly and allows an equally simple disassembly especially for repair and maintenance purposes.
  • the sub-housing can also be retrofitted with additional components of the air conditioning device to expand the device. The device thus allows an extension of an existing air conditioning device, without requiring additional cutouts in the floor, in particular an intermediate floor with the floor covering laid thereon, or in a ceiling panel are required.
  • the housing and the sub-housing form a stable unit for receiving all provided components of the air conditioning device.
  • the housing and the sub-housing attached thereto form a substantially rigid unit. This simplifies the alignment of the device, wherein optionally the housing may partially support the sub-housing, namely preferably one side of the sub-housing. Alternatively, it would also be conceivable to install the housing and the secondary housing separately and then to connect both.
  • the secondary opening is arranged in that wall of the housing and / or the secondary housing, with which the secondary housing is connected to the housing.
  • the secondary opening is thus surrounded by the secondary housing.
  • the secondary opening is preferably in a longitudinal side wall of the housing.
  • the secondary housing may have a corresponding secondary opening.
  • the sub-housing has on the housing pointing side over no wall, in particular no longitudinal side wall, so that with a correspondingly large secondary opening in the longitudinal side wall of the housing, the entire side of the secondary housing is open and thereby fully accessible for assembly and disassembly.
  • the base area of the secondary housing is preferably somewhat smaller than the base area of the housing.
  • the base of the secondary housing is at least narrower than the base of the housing. This makes it possible to use a component of the air-conditioning device which fills the entire base area of the secondary housing, optionally several components already connected to one another, through the larger opening in the housing and to insert it through the secondary opening out of the housing into the secondary housing.
  • the sub-housing is slightly shorter than the housing, whereby a part of the surface of the longitudinal side wall of the housing is released from the sub-housing. This residual surface of the side housing facing the longitudinal side surface of the housing is available for connections, both liquid-carrying lines or hoses and cables available.
  • the height of the secondary housing is less than the height of the housing, wherein preferably a top or bottom of the secondary housing relative to the plane of the coverable by the at least one grid opening in the housing is set back.
  • the lower sub-housing may be arranged below a floor covering, for example a double floor, a cavity floor or other flooring, or over a ceiling panel or false ceiling.
  • the sub-housing can be inserted before the assembly of the housing through the cutout for the housing in the bottom surface or ceiling surface in the space below the raised floor or above a ceiling panel. It can be used as the cutout for the coverable by at least one grid housing to mount the sub-housing. A separate from at least one separate grid coverable cutout for the secondary housing is unnecessary.
  • the secondary housing is preferably provided to associate the secondary housing with guides for inserting at least one part of the air-conditioning device or individual components thereof. This facilitates the lateral insertion of parts or components of the air-conditioning device into the sub-housing from the housing.
  • the housing has at least one passage opening and at least one connection carrier corresponding thereto, which are formed corresponding to one another in such a way that the connection carrier with mounted connections and / or cables can be passed through the passage opening.
  • the passage opening and the connection carrier can be designed such that the latter can be pushed or pushed through the housing and can preferably also be fastened to the passage opening or into the passage opening.
  • the at least one connection carrier can be provided with connections or cables and subsequently used as a prefabricated connection unit in the housing and / or connected to the same.
  • the assembly of the device is thereby simplified.
  • the connections can be mounted on the connection carrier before the housing and other components of the air conditioning unit are mounted.
  • cables can be provided with plugs before the installation of the air-conditioning device in the housing and optionally the secondary housing and the plug can be mounted on the connection carrier.
  • connection carrier in an extension direction is the same, preferably slightly smaller than the corresponding dimension of the passage opening of the housing. Then the dimension of the connection carrier in a different extension direction may be greater than the passage opening. In spite of this, the connection carrier can still be pushed through or inserted into the passage opening of the housing, even with mounted connections or cables.
  • connection carrier with a U-shaped cross-section.
  • connection carrier receives two parallel legs and a web connecting them.
  • the two parallel legs make it possible to fasten cable connectors on the one hand in the connection carrier and on the other hand provide a strain relief for the respective cable.
  • the connection carrier thereby fulfills all the necessary installation tasks, in particular for cables. After all connections are mounted on the connection carrier, only the connection carrier needs to be connected to the housing in order to have all the connections for supplying the air conditioning device with at least electrical energy to the housing, in particular in the housing available. After the required components of the air conditioning device have been inserted into the housing and the sub-housing, only need the plugs of the cables of the air conditioning in the corresponding plug of the connection carrier to be plugged in to complete the installation of the air conditioning device.
  • connection carrier is provided according to a preferred embodiment of the invention with opposite cuts in the web, which adjoin the legs holding the cable connector.
  • An incision may serve for the insertion of the connection carrier into the housing for the entry of an edge region of the connection carrier receiving through opening of the housing.
  • the connection carrier is in this way for passing through the opening back and forth in the same.
  • the leg, behind which the notches in the web are located can have a dimension in the direction of the cuts which exceeds the dimension of the passage opening in the corresponding direction.
  • the leg of the connection carrier carrying the cable connectors is wider than the passage opening for the connection carrier in the housing. Then the height of the leg is equal to or slightly smaller than the height of the passage opening. Despite the fact that a larger area than the passage opening having leg of the wider connection carrier can be pushed through the passage opening.
  • the incisions make it possible to move the connection carrier, which is inserted through the inlet opening of the housing with the leg, in front of the passage opening and to place it centrally in front of the passage opening.

  • the heat exchanger 56 and the cross-flow fan 57 are juxtaposed longitudinally in the tub insert 53, wherein the cross-flow fan 57 is located on the outside air fan unit 50 in the side housing 17 facing side of the housing 10 ( Fig. 4 ).
  • a recirculating air flow is generated. In this case, room air is sucked in and conducted past the heat exchanger 56. Above the heat exchanger 56 passes from this heated or cooled circulating air back into the room.
  • the cross-flow fan 57 thus serves as a circulating air fan.
  • fresh air can also be conducted past the heat exchanger 50 by the outside air fan unit 50 in the secondary housing 17 and thereby cooled or heated. Fresh air can also flow into the room without cooling or heating.
  • connection carrier 34 For this purpose, not shown cable connector, in particular the centrifugal fan 51, the cross-flow fan 57 and the drive 54 for the outside air damper 27 and the controller with the cable connectors 44 of the connection carrier 34 are connected.
  • the lines of the heat exchanger 56 are connected to the valves 48 by the couplings 47, preferably in the form of quick-release closures.
  • the device is then basically ready for use. It is only the opening 16 in the housing 10 still by a grate 58, for example, a transverse or a longitudinal grid to close. It can also be provided several separate grates.
  • a cover 59 and a filter web 60 lying thereon are provided above the heat exchanger 56 and the crossflow fan 57.
  • the cover 59 is preferably supported in or on the housing 10 to serve as a support for the grate 58.
  • the heat exchanger 56 and the crossflow fan 57 left-side compartment of the housing 10 by the cable connector 44 on the connection carrier 34 and the couplings 47, the valves 48 and the shut-off valves 49 are still a control 61 is arranged ,
  • the spaces in opposite end portions of the housing 10 for receiving the outside air damper 27 with the drive 54 on the one hand and cable connector 44, couplings 47, valves 48, shut-off valves 49 and the controller 61 on the other hand are by top from the opening 16 of the housing 10 used covers 62, 63 closed.
  • the cover 62, 63 are loosely placed on the opening 16 of the housing 10, so that they can be removed in particular for maintenance purposes.
  • the grate 58 extends, thereby closing the entire opening 16 of the housing 10 upwards.
  • the top of the grate 58 preferably terminates flush with the surface of the false floor.
  • the invention is suitable not only for the air conditioning device shown in the figures, but for any configured and constructed air conditioning devices, including those that do not serve for ventilation, cooling and heating, but only meet some of the above air conditioning tasks. It is also conceivable that the device or the air conditioning device has only a single fan, so that the cross-flow fan 57 serving as a recirculation fan is omitted. It is also conceivable that the device has no ventilation option with outside air. Such a device requires no outside air connection. The air conditioning device is then formed from a pure recirculation unit, which preferably has a greater cooling capacity than the device described with an outside air unit.
  • the invention is also suitable for suspended under a ceiling ceiling devices for air conditioning of rooms. Such devices are arranged between a floor slab and a false ceiling.
  • the housing is provided on the undersides with a ceiling grid, the sub-housing is located in the room above the false ceiling and is covered by this.
