[0059] FIG. 1 shows a system 100 according to the invention for treating air 91 in a building interior 90 of a building (not shown in greater detail) in an operating state 1. The system 100 can be used, for example, in newly constructed, renovated or dilapidated buildings or parts of buildings and serves, in particular, to create an ambient climate suitable for drying building parts, such as a building floor 93, a building wall 94 or a building ceiling 95. In particular, in the case of new buildings extending over a plurality of floors, for example, a high-rise building, the system 100, which is particularly suitable for an autonomous operation, can be used particularly advantageously.

[0060] In the application shown in FIG. 1, in particular a floor application in which the system components are operated as floor-standing devices on a floor, the system 100 is provided, for example, for drying a floor 93 of the room 90, in particular the screed. In the present case, the system 100 comprises, in particular, a separately operated first ventilator module 10a, a second ventilator module 10b coupled to a first air treatment unit 20, a third ventilator module 10c coupled to a second air treatment unit 30, a first auxiliary module 40 and a second auxiliary module 50.

[0061] In the present case, the ventilator modules 10, 10a, 10b, 10c, which are each also referred to as the ventilator device 101, are always constructed and designed in the same way, in particular as shown in detail in FIG. 4. Due to their structural design, in particular with an optimized soundproof housing, all modules, in particular the ventilator module 10, 10a, 10b, 10c and the air treatment unit 20, 30, are particularly quiet when in operation.

[0062] The separately operated first ventilator module 10a is used in the present case exclusively to generate a uniform and homogeneous air circulation in the entire room 90. The use of a separately operated ventilator module 10 is therefore advantageous, particularly in the case of particularly large rooms 90. The ventilator module 10a can, in this case, be viewed as a device in the system 100 which supports the drying effect, for example, the drying of a newly produced building floor 93, in particular a screed floor.

[0063] The second ventilator module 10b coupled to the first air treatment unit 20 is used in the present case, in particular to convey an air flow through the air treatment unit 20. The air treatment unit 20 as such is shown in more detail in FIG. 5. The air treatment unit 20 comprises a housing 24 which forms a flow channel having a flow center line S. The air treatment unit 20 is designed, in particular, as a cooling module 25, which comprises a condenser 27 along which the air flow generated by the second ventilator module 10b can flow, in particular a cooled condenser, as well as a cooling device 26 that serves to cool the condenser 27. As a result, moisture can be removed from the air 91 when it flows along the cooled condenser 27, in particular due to a corresponding condensation of the moisture on the condenser 27. The cooling device 26 can, in particular, be designed as a heat pump known per se. The air flow is guided through the air treatment unit 20, in particular from an upper face 28 to a lower face 29. For this purpose, at least one air inlet opening 21 is advantageously provided on the upper face 28, and at least one air outlet opening 22 is provided on the lower face 29, which is shown, in particular, in FIG. 5. The air flow is particularly preferably conveyed through the air treatment unit 20 in a rectilinear manner, i.e., without loops. On the lower face 29, the air flow is conveyed from the air treatment unit 20 into the ventilator module 10b through at least the one outlet opening 22, which is correspondingly arranged with the inlet opening 11a, 11b of the ventilator module 10b. The air dried in the air treatment unit 20 can then be released again into the room 90 through corresponding outlet openings 7 by means of the second ventilator module 10b. The water absorbed or deposited in the air treatment unit 20 during the dehumidification and collected by means of a trough 23 is not permanently collected in the air treatment unit 20 but instead is conveyed to the auxiliary module 40 via a water hose 42. For this purpose, for example, a water hose 42 can be connected to a connection 42a on the air treatment unit 20. Furthermore, a pump 42a for conveying the water through the water hose 42 can be provided on the air treatment unit 20.

[0064] The auxiliary module 40 comprises, in the present case, a liquid tank 41, in particular a water tank, in which the water supplied by one or more air treatment units 20 and via one or more water hoses 42 can be collected. The auxiliary module 40 is therefore advantageously set up on a centrally located building corridor, in the case of multi-level buildings optimally in each case on one level of the building. For a better overview, FIG. 1 only shows a single water hose 42 connected to the auxiliary module 40, but, in principle, a plurality of water hoses 42 can be connected to the auxiliary module 40 at the same time. In principle, the water hose 42 can also have means for an electrical connection, for example, for the transmission of data signals, for example, through a cable duct running parallel to the water hose. The auxiliary module 40 comprises a water extraction point 43 on one side, via which the water temporarily stored in the water tank 41 can be removed as needed. The water extraction point 43 is designed, for example, as a water faucet from which the water stored in the water tank 41 can be tapped. The tapped water can be used, for example, on construction sites to mix mortar or concrete. As a result, the long supply hoses and/or long work paths usually provided for this purpose of making water available to a respective work location are no longer required. Furthermore, an autonomous operation is made possible over a particularly long period of time. The auxiliary module 40 also comprises a display and input device 63, which is described in more detail below.

[0065] The third ventilator module 10c coupled to the second air treatment unit 30 is used in the present case, in particular to convey an air flow through the second air treatment unit 30. The air treatment unit 30 as such is shown in more detail in FIG. 6. The air treatment unit 30 comprises a housing 34 with a flow channel having a flow center line S and is designed, in particular, as a heating module 35, comprising, in particular, a heatable heating element 37 through which and along which an air flow generated by the third ventilator module 10c flows, as well as a heating device 36 for heating the heating element 37, in particular a mini burner. As shown in FIG. 6, the heating element 37 can, for example, be designed as a combustion chamber 33. As a result, heat can be supplied to the air 91 when the air flows through or over the heated heating element 37. The air flow is guided through the air treatment unit 30, in particular from an upper face 38 to a lower face 39. For this purpose, at least one air inlet opening 31 is advantageously provided on the upper face 38, and at least one air outlet opening 32 is provided on the lower face 39. The air flows particularly preferably in a straight line, i.e., it passes through the air treatment unit 30 without any reversing or meandering of the air flow. On the lower face 39, the air flow is guided from the air treatment unit 30 through the at least one outlet opening 32 correspondingly arranged with an inlet opening 11a, 11b of the ventilator module 10c into the ventilator module 10c. The air heated in the air treatment unit 30 can then be released again into the room 90 through corresponding outlet openings 7 by means of the third ventilator module 10c.

[0066] In principle, the heating device 36 can be operated electrically, with gas or with oil. In the present case, the heating device 36 is operated by means of heating oil, which is supplied from the auxiliary module 50 to the heating device 36 via a heating oil hose 52 that can be connected to the air treatment unit 30, in particular to a connection 54. The supply of heat by means of an oil-operated burner is particularly advantageous in that the air to be heated is not supplied with moisture, as is the case with gas firing, so that the overall drying efficiency for the room 90 is not adversely affected. The exhaust gases produced during the combustion in the heating device 36 can be removed from the room 90 or from the entire building in a particularly simple manner via an exhaust hose 53 that can be connected to the air treatment unit 30, in particular to a connection 55.

[0067] The auxiliary module 50 comprising a heating oil tank 51 is advantageously arranged outside the building, preferably in a secured region of a construction site that is easily accessible by a tanker. If the construction site comprises a plurality of individual buildings, the auxiliary module 50 is preferably arranged centrally to these buildings so that the air treatment units 30 located in each building are particularly advantageously supplied with heating oil. For this purpose, a plurality of individual heating oil hoses 52 can, of course, be arranged on the auxiliary module 50, which is not shown here for clarity purposes. In principle, the heating oil hose 52 can also have means for an electrical connection, for example for the transmission of data signals, for example through a cable duct running parallel to the heating oil hose. The auxiliary module 50 can also comprise a display and an input device 63, which is not shown here.

[0068] As can be seen, in particular from FIG. 1, each of the system components 10, 20, 30, 40, 80 comprises, with the exception of the heating oil tank 50, a coupling device 17 or 61 and a counter-coupling device 18. The coupling device 61 is constructed in the same way as the coupling device 17; accordingly, what is stated below for the coupling device 17 likewise applies to the coupling device 61. Due to the design of the coupling device 17 and the counter-coupling device 18, in particular, the ventilator module 10 can be fastened to the respective air treatment unit 20, 30. With the exception of the heating oil tank 50, it is also possible to fasten all system components 10, 20, 30, 40 to one another, for example, for application purposes or for transport purposes. In particular, this allows for a quick and uncomplicated exchangeability of the component that is frequently subjected to the highest stress on a construction site, in particular the ventilator module 10. Furthermore, a plurality of individual system components 10, 20, 30, 40 can, for example, be transported at the same time in a safe and convenient manner.

[0069] In the present example, the coupling device 17 comprises a total of four first coupling elements 17a and at least two second coupling elements 17b. The coupling elements 17a, 17b are preferably each arranged in a corner region of an upper face 12, 28, 38, 44 of a respective system component 10, 20, 30, 40. The coupling device 17 in the ventilator module 10 is arranged on the upper face 12, in the air treatment unit 20 designed as a cooling module 25 on the upper face 28, in the air treatment unit 30 designed as a heating module 35 on the upper face 38 and on the auxiliary module 40 on the upper face 44. The first coupling elements 17a are used, in particular, for a mechanical coupling or fastening and the second coupling elements 17b for an electrical connection. It can be provided that the first coupling part 17a and the second coupling part 17b are realized by a common component, for example, a protruding pin or web made of an electrically conductive material.

[0070] The counter-coupling device 18 is correspondingly arranged on a lower face 13, 29, 39 of a respective system component 10, 20, 30, 40 and, in the present example, comprises a total of four first counter-coupling elements 18a and at least two second counter-coupling elements 18b. In the ventilation module 10, the counter-coupling device 18 is arranged on the lower face 13, in the air treatment unit 20 designed as a cooling module 25 on the lower face 29, in the air treatment unit 30 designed as a heating module 35 on the lower face 39 and on the auxiliary module 40 on the lower face 45.

[0071] In turn, the first counter-coupling elements 18a serve for a mechanical coupling or fastening and the second counter-coupling elements 18b for an electrical connection. It can be provided that the first coupling part 17a and the second coupling part 17b are realized by a common component, for example, a receptacle made from an electrically conductive material for the coupling device 17 designed as a protruding pin or web. To establish an electrical connection, it is provided, in particular, that, in a coupled state, at least the second coupling element 17b rests against the second counter-coupling element 18b or comes into contact with the same.

[0072] An essential feature of the invention is the electrical interconnection of the individual system components 10, 20, 30, 40, 50 with one another, in particular for control and/or regulation purposes. The ventilator module 10, the air treatment unit 20, 30 and/or the auxiliary module 40, 50 therefore comprises at least one control and/or regulation module 80. In FIG. 1, the control and/or regulation module 80 is arranged on the auxiliary module 40, for example, and in the example shown in FIG. 4, on the ventilator module 10. In FIG. 7, the control and/or regulation module 80 is shown as a separately designed unit that can be coupled to the other system components 10, 20, 30, 40.

[0073] The control and/or regulation module 80 is used, in particular, for the autonomous control and/or regulation of at least one of the system components 10, 20, 30, 40, 50. For this purpose, the control and/or regulation module 80 is electrically connected to each of the system components 10, 20, 30, 40, 50 for the transmission of data signals via electrical connecting lines 42, 52, 83. The connecting line 83 is designed as a conventional cable, and the connecting lines 42, 52 are designed as electrical lines arranged parallel to a respective fluid hose and attached thereto.

[0074] The control and/or regulation module 80 can, in particular, be part of a computer unit 62 and is used, in particular, to record environmental parameters 92 that are prevalent in the current environment. For this purpose, the control and/or regulation module 80 comprises at least one detection sensor 81 for detecting at least one environmental parameter 92. The at least one detection sensor 81 can, for example, be used to detect an ambient temperature, an ambient air humidity, an ambient movement, an intrinsic movement, an ambient brightness, a connection to an external voltage supply, a battery power, a tank fill level, a removal of a water container, a tensile stress on a support device 71, a distance to at least one building wall 94 and/or building ceiling 95, a type of installation and/or an operating mode.

[0075] The control and/or regulation module 80 comprises an evaluation module 82 for evaluating the recorded data. Just like the computer unit 62, the evaluation module 82 serves for storing, calculating and/or outputting data, in particular data signals. As a result, the parameters detected by means of detection device 81 can be evaluated by means of the evaluation module 82, and this resulting data can be used to control and/or regulate the individual system components 10, 20, 30, 40, 50. When used for drying a building wall 94 with a detected decreasing air humidity in the room 90, for example, the output of the drive motor 14a of the fan wheel 14 of the ventilator module 10b coupled to the air treatment unit 20 as well as the heating oil supply into the air treatment unit 30 can be decreased while the output of the drive motor 14a of the fan wheel 14 of the ventilator module 10a can be increased in order to allow for an optimal air circulation in the entire room 90, in particular along the building wall 94, in particular for removing moisture from the building wall 94 into the air 91.

[0076] The display and input device 63 provided by way of example on the auxiliary module 40 in FIG. 1 can, in principle, be arranged on any component 10, 20, 30, 40, 50 of the system 100. In FIG. 4, the arrangement of the display and input device 63 on the ventilator module 10 is shown as an example. The display and input device 63 is used, in particular, to display information about, for example, the respective system component 10, 20, 30, 40, 50 such as an operating state, in the present example in FIG. 1 regarding a fill level of the water tank 41, and/or regarding ambient conditions 92, such as the ambient temperature or the ambient humidity. Preferably, additional data, values or the like, for example, data for controlling and/or regulating a respective system component 10, 20, 30, 40, 50, can be input by means of the display and input device 63. For this purpose, the display and input device 63 can be designed, for example, in the form of a so-called touchpad display. Alternatively, the data can be displayed and/or entered via a mobile device, in particular a smart device such as a tablet, smartphone or the like.

[0077] In principle, the display and input device 63 can be part of a computer unit 62 comprising further electronic modules or components, as shown by way of example in FIG. 4. A communication module 64, a data communication interface 65 and/or a GPS module 66 can also be provided, for example.

[0078] The communication module 64 can, in particular, serve for the forwarding and/or processing of data signals, in particular bus or field bus data, for example, for the control and/or regulation of the individual system components 10, 20, 30, 40, 50. Furthermore, the communication module 64 can be designed to be particularly suitable for transmitting and receiving data via the Internet so that control and/or regulation of the system components 10, 20, 30, 40, 50 is also possible via the Internet.

[0079] The data communication interface 65 is used, in particular, for a connection to a network or a separate external device on site. The data communication interface 65 can, for example, be designed as a USB interface to which an external input/output device such as a mobile phone, tablet or laptop can be connected. This allows for a relatively convenient operation of the system 100, particularly when the system 100 is started up, serviced or repaired, in particular on a construction site. For a particularly convenient operation of the system 100, the data communication interface 65 can be designed as a so-called wireless data communication interface, which, for example, comprises a radio antenna for a Bluetooth or WLAN connection, for example. In particular, it is provided that all system components 10, 20, 30, 40, 50 can be operated, in particular controlled or read, from a single data communication interface 65 by means of a corresponding networking. The networking of the system components 10, 20, 30, 40, 50 can be established, for example, with a Bluetooth or WLAN network connection generated by the data communication interface 65 and/or the communication module 64.

[0080] The GPS module 66 is used, in particular, to locate a respective device, for example, when it is not used and stored in a warehouse, when used on a construction site or when the respective system components 10, 20, 30, 40, 50 having the GPS module 66 are stolen. The GPS module 66 can, in particular, comprise a rechargeable battery in order to be able to transmit/receive signals in the event of a theft.

[0081] To avoid having a large number of separate items in a room 90 of a building under construction, it is provided that a light 67 is arranged on the ventilator module 10, in particular on the upper face side 12, which is suitable for lighting a room 90. For this purpose, the light 67 can have, for example, at least one light source, such as an LED, which, in particular when the ventilator module 10 is arranged on a building ceiling 95, is suitable for lighting a room with a size of approximately 40 m.sup.2. Such a light 67 can, of course, also be arranged on the other system components 20, 30, 40, 50. A circumferential light band can be arranged on the upper face of the heating oil tank 50, for example, in order to increase safety.

[0082] To avoid complex cabling and separate electrical distributors in a room 90, a respective system component 10, 20, 30, 40, 50 can comprise an electrical distribution device 68 with at least one electrical plug connection 69. The system components 10, 20, 30, 40 per se or also other devices, such as construction machines, tools, battery chargers or the like, can be connected to the plug connection 69 for a power supply. Power can be provided to the individual system components 10, 20, 30, 40, for example, by an external power supply or by an accumulator 73, as shown by way of example in FIG. 4 on the ventilator module 10.

[0083] In FIG. 2, the ventilator module 10a, which is also referred to as the ventilator device 101, is shown in an operating state 1 and is used as a wall unit. The ventilator module 10a is arranged on a building wall 94 of a room 90, in particular with the lower face 13 resting against the housing wall 94. The ventilator module 10a can be fasted the wall 94 by means of, for example, a wall mounting device 70—optionally also designed as a module—which can comprise fastening screws (not shown in more detail), or by means of a strap system 71.

[0084] The strap system 71, which is shown, in particular, in the transport state 2 shown in FIG. 3, is used, in particular, to fasten a system component 10, 20, 30, 40 to a building wall 94 or ceiling 95 and also to primarily facilitate the transport of the respective system component 10, 20, 30, 40. FIG. 3 shows a transport state, in particular, for transporting four identically designed ventilator modules 10 or ventilator devices 101, with three additional ventilator modules 3 designed in the same way as the first ventilator module 10 being stacked on the upper face of a first ventilator module 10. The strap system 71, also called a support device, is arranged on a housing wall 9 of one of the ventilator modules 3, 10. The support device 71 comprises two straps 72a, 72b, which are preferably adjustable in length, with each arranged on a holding plate 75. The holding plate 75 can be designed as a metal plate, for example, which can be fixed to the housing wall 9 of the ventilator modules 3, 10 via a fastening system, for example, a rail system, which is preferably arranged on the rear of the metal plate, and which can, in particular, be inserted and locked in a receptacle arranged on the side wall. As a result, according to the present example 4, ventilator modules 10, which are generally relatively lightweight, can be particularly comfortably carried or transported via the strap system 71 by a person in the manner of a backpack.

[0085] The ventilator module 10, 10a, 10b, 10c comprises—as shown, in particular, in FIG. 4—a housing 11 with an upper face 12 and an opposite lower face 13. Between the upper face 12 and the lower face 13, a flow channel 19 formed by the housing 11 extends in which, approximately in the middle M of a height between the upper face 12 and the lower face 13, an impeller 14, which can be rotated about a rotational axis A and set in rotation by a drive motor 14a, is arranged for conveying an air flow 91 through the flow channel 19. The rotational axis A is aligned substantially perpendicular to a stand surface 16 of the ventilator module 10, which is formed on the lower face 13 by a housing base 15.

[0086] In the present case, the upper face 12 and the lower face 13 are not only to be understood as the respective forming end or upper face 12a, 13a of the respective side 12, 13 but rather a region or portion between the respective end surface 12a, 13a and the middle M of the height of the ventilator module 10 extending across a height portion. In FIG. 4, for example, the lower face 13 extends across the region 8.

[0087] In the present case, at least one inlet opening 11a, 11b for taking or sucking in air 91 from the environment 90 into the flow channel 19, which in the present case is, in particular, ring-shaped, is arranged on the upper face 12. The flow channel 19 then extends from the inlet opening 11a, 11b in the direction of the lower face 13, and, in the present case, opens there, among other things, into lateral outlet openings 7, in particular, surrounding the housing 11. As a result, the air 91 taken in at the upper face 12 can be accelerated by means of the impeller 14 and blown out at the lower face 13 in the lateral direction away from the ventilator module 10 into the room 90 so that the blown air can initially flow along the building floor 93 and thus create an air circulation in the entire room 90. In the present case, a plurality of guide bodies 6, in particular arranged in series, are provided between the outlet openings 7 and the impeller 14.

[0088] The guide bodies 6 serve, in particular, to align the air flow blown out of the ventilator module and to close the outlet openings 7 as needed. The air flow 91 can, in particular, flow out of the ventilator module 10 in a plurality of directions in the room, all around, preferably substantially in a spatial plane E, parallel to the stand surface 16. As a result, the air flow can be directed uniformly and homogeneously across a building floor 93 to be dried in a particularly suitable manner. For this purpose, the guide bodies 6, which are preferably arranged in series, can be adjustable, in particular rotatable, with suitable means being provided to ensure that all guide bodies 6 are adjusted to the same extent by an adjustment of a single guide body 6.

[0089] Optionally, lower face outlet openings 5, which can be opened as needed, can be alternatively or additionally provided on the lower face 13, in particular in the region of the stand surface 16, in particular, if necessary. These floor outlet openings 5 make it possible for an air flow to be blown out by the ventilator module 10 directly onto or in the direction of a part of the building against which the ventilator module 10 rests with the lower face 13, in particular a building floor 93, a building wall 94 or a building ceiling 95. Such an air flow can be used, for example, for the drying of screed in which air, which is usually supplied by means of air hoses, is introduced into the sub-floor of the screed through holes or bores made in the screed. To avoid an unwanted secondary flow effect and to improve the stability of the ventilator module 10, sealing bellows 4 can be provided on the lower face 13, as in the present case. The housing base 15 and the stand surface 16 can be formed by the bellows 4. The bellows 4, which are preferably made of rubber, are formed circumferentially on the end face 13a of the lower face 13 and can seal an intermediate space formed between the end face 13a and the building part 93, 94, 95.

[0090] As can be seen, in particular in FIG. 4, a particulate filter 74, in particular a HEPA filter, is provided in the region of the inlet opening 11a, 11b of the ventilator module 10, which is not shown in greater detail for clarity purposes. As a result, suspended substances and larger particles occurring in the air 91 can be filtered, which makes it possible to permanently guarantee the functionality of the ventilator module 10, in particular the impeller 14.

[0091] The control and/or regulation module 80 shown in more detail in FIG. 7 comprises in this example the detection sensor 81, which protrudes between an air outlet on upper face the module 80, which is not shown in more detail at the top of FIG. 7, and a flow channel 84 for by an air outlet, which is not shown in more detail either, with said sensor being connected to an evaluation module 82, which is formed in the present case as a component. Furthermore, the control and/or regulation module 80 comprises, in the present case, a display and input device 63 which is connected to a computer unit 62. In addition, a communication module 64, a data interface 65 and a GPS module 66 are provided for a remote monitoring or data input, for example. In addition, the control and/or regulation module 80 comprises a circumferential light 67 on the upper face for an optional lighting of a room 90. Like the other system components 10, 20, 30, 40, the control and/or regulation module 80 also comprises a coupling device 61 on the upper face and a counter-coupling device 18 on the lower face. The control and/or regulation module 80 can thus optionally be placed as a module on a ventilator module 10 or another system component 20, 30, 40 and attached thereto. In one operation of the system 100, a preferred structure of interconnected and fastened system components 10, 20, 30, 40, 80 in the order from top to bottom is the control and/or regulation module 80, the air treatment unit 20, 30 and the ventilator module 10.

[0092] Of course, the system components not explicitly shown as such in the figures, in particular the evaluation module 82, the display module 63, the communication module 64, the GPS module 66, the light module 67, the accumulator module 73 and the filter module 74, can each be designed as a separate module, which can optionally comprise a coupling and counter-coupling device in order to be coupled to another system component.

[0093] It should be clear that the scope of protection of the present invention is not limited to the embodiments described. In particular, the number of system components to be used, as well as their structure and arrangement, are not subject to any limits and can be modified without changing the core of the invention.
