Description

[0001] The present invention relates to a supply device for supplying a usage unit with heat, cold, hot water and / or air and the use thereof.

[0002] Furthermore, the present invention relates to the use of a plurality of supply devices according to the invention for the decentralized arrangement and regulation / control of heating systems, cooling systems, heat recovery systems, hot water production systems and / or air duct systems on the facade or outer wall of a plurality of usage units of a building.

[0003] Furthermore, the present invention relates to a method for replacing a supply device in a building that is equipped with one or a plurality of supply devices.

[0004] CO2 emissions must be reduced in residential construction. The greatest savings potential comes from eliminating fossil fuels such as coal (e.g., lignite), oil, or gas for heating buildings or generating electricity.

[0005] The share of renewable energies is growing. 35% of electricity generation in Germany already comes from renewable energy sources. In new single-family home construction, for example, air-water heat pumps have overtaken oil and gas boilers.

[0006] Air, earth, and water are energy sources that are environmentally friendly and free of charge and are incorporated into intelligent heat pump technology. Heat pumps make you independent of fossil fuels and help reduce heating costs. Depending on the energy source, there are various heat pump systems, of which the air-to-air heat pump is the most commonly used.

[0007] Modern residential construction is looking for solutions to utilize more renewable energy. Air (heat from the air) is infinitely available as renewable energy, and a heat pump harnesses this energy to generate heat. Thermodynamics and state-of-the-art frequency-controlled compressors have transformed air-to-air heat pumps into highly efficient heating and cooling systems.

[0008] In today's buildings, supply systems are usually located centrally, usually in the basement or on the roof of a building. This has the disadvantage that supply lines must be routed from these central systems, for example, from the burner of a central heating system or an air conditioning system, to the individual rooms. This increases the effort required for the planning and construction of a building. Expanding a building is often not feasible because already installed supply lines to centrally located supply systems cannot be adapted to a larger usable area.

[0009] In addition, heat loss may occur during the transport of, for example, warm water to the individual rooms, or additional construction measures may be required to insulate the supply lines.

[0010] EP 1 593 915 A1 describes a thermal cooling device for cooling, heating and the preparation of hot domestic water.

[0011] The object of the present invention is therefore to provide a device which makes it possible to ensure self-sufficient, decentralized cooling and / or heating of a room and also a hot water supply to the room.

[0012] The object of the present invention is achieved by a supply device of the type mentioned at the outset, comprising a housing which can be fixed to a facade or an outer wall of a room of the usage unit, wherein at least one external device of a supply unit is arranged in the housing, wherein the housing has one or more fixing means with which the housing can be reversibly fixed to the facade or the outer wall of a room of the usage unit, wherein at the points at which the supply device can be fixed to the facade or outer wall and on the supply device itself interfaces orConnections are arranged which can be connected to one another when the supply device is fixed to the facade or outer wall, and wherein the housing and the facade or the outer wall of the room of the usage unit have openings and connections with which the supply units arranged in the housing can be connected to supply lines which lead through the facade or outer wall into the room.

[0013] The device opens up the possibility for project developers and building owners to switch from centralized heating / cooling / hot water / ventilation technology to decentralized systems. Such a decentralized arrangement of supply technology offers numerous advantages. For example, units (apartments, offices, hotel rooms) can be developed, supplied, and operated almost autonomously, as they are independent of central technical systems. Only a reduced infrastructure for water, sewage, and electricity is still required in the building.

[0014] In this way, renewable energies can be used and CO2 emissions are significantly reduced when electricity from renewable sources is used.

[0015] Furthermore, the billing effort for the utility costs of a unit (apartment, office, hotel room) can be reduced, as only electricity and cold water consumption need to be billed. Furthermore, legionella testing is eliminated, as the water volume per unit is kept small. Large storage and storage of hot water is also eliminated.

[0016] With this device, systems that utilize renewable energy "air" can be mounted on or integrated into facades in an architecturally and, above all, technically correct manner. Due to their modular design, the devices adapt perfectly to any building and any type of unit. These technical devices also accelerate the construction process and significantly improve the quality of the pre-installed systems, as the system technology is pre-assembled in the devices in the factory.

[0017] The supply unit (within a usage unit [indoor unit]) is preferably a heating system, cooling system, air duct system, air conditioning system, heat recovery system, hot water system, air purification system, underfloor heating or a combination of these.

[0018] The outdoor unit of the supply unit is preferably a device for generating heat, cold and / or hot water or a device for ventilating a usage unit or a room of a usage unit.

[0019] The outdoor unit is preferably an air-to-air heat pump or air-to-water heat pump.

[0020] The supply line is preferably a control line, power line, supply air line, exhaust air line, condensate line, flow and return line or refrigerant line.

[0021] The housing preferably has an inspection opening or inspection flap that allows access to the supply units.

[0022] The housing (or device) preferably has vibration dampers and / or sound decoupling mounts with which the supply units installed in the device are dampened so that no unwanted noise penetrates into the usage unit.

[0023] In the event of a malfunction, only one unit is affected, not all units, as is the case in buildings with central supply units. To quickly resolve the malfunction, the entire device or just the affected supply unit or its supply lines can be replaced.

[0024] The housing (or the device) preferably has a receptacle for a crane fork or at least one crane eye. This allows the device to be lifted with a crane and removed from the facade / exterior wall, or a new device can be lifted to the desired location on the facade / exterior wall, thus significantly simplifying the replacement of the device, even in tall buildings.

[0025] The housing (or device) preferably has a control unit or an interface to a supply unit in the unit. This increases comfort for each unit, as a user of the supply device can adjust the most comfortable parameters of the unit (heating, cooling, hot water, air supply, air purification, and heat recovery).

[0026] A further advantage is that the user can reduce the additional costs for heating, cooling, hot water production and / or ventilation through his or her own behavior.

[0027] A further advantage of the decentralized device is that in the event of excess electricity production from wind and solar power, the supply units (for example a hot water tank of a heat pump) can store energy in the form of hot water.

[0028] Furthermore, the object of the present invention is achieved by using a plurality of supply devices according to the invention for the (autonomous) decentralized arrangement and regulation / control of heating systems, cooling systems, heat recovery systems, hot water production systems and / or air duct systems on the facade or outer wall of a plurality of usage units of a building.

[0029] Furthermore, the object of the present invention is achieved by using the hot water generated by the supply device to operate an underfloor heating system in the rooms (bathroom, kitchen, living room, etc.) of the usage unit.

[0030] Furthermore, the object of the present invention is achieved by a method of the type described above, in which the housing is released or removed by releasing or removing the at least one fixing means and is replaced by a new housing, which is then reversibly fixed to the facade or the room of the usage unit with at least one fixing means, and by separating and connecting the connections (of the supply lines), whereby the supply units are activated or ready for operation.

[0031] The supply unit preferably connected is a heating system, cooling system, air duct system, heat recovery system, hot water production system (hot water preparation system) or air purification system.

[0032] Further details, features and advantages of embodiments of the invention emerge from the following description of embodiments with reference to the associated figures.

[0033] Show in detail Fig. 1 a schematic representation of the housing of a supply device according to the invention (plan, view, section) for a technical unit, Fig. 2 two three-dimensional representations of the Fig. 1 shown housing from different sides (front, back), Fig. 3 a schematic representation of the housing of a supply device according to the invention (plan, view, section) for two technical units, Fig. 4 two three-dimensional representations of the Fig. 3 shown housing from different sides (front, back), Fig. 5 a schematic representation of the housing of the Fig. 3 and Fig. 4 shown supply device with supply devices and supply connections arranged in the housing, Fig. 6 two three-dimensional representations of the Fig. 5 shown housing from different sides (front, back), Fig. 7 a floor plan of a usage unit with a supply device according to the invention arranged on the facade, Fig. 8 a section through a building with several supply devices according to the invention arranged on the facade and Fig. 9 a three-dimensional representation of the arrangement of several supply devices on the facade / external wall of a building.

[0034] The supply device (the climate box module) 1 is used to accommodate decentralized supply units that, for example, heat / cool, heat water and ventilate based on renewable energies.

[0035] Supply device 1, including the supply units and their supply lines and operating devices, is pre-assembled in series production to improve the technical quality of the installation. The assembly quality of the system technology used (supply units for heating / cooling / ventilation / hot water production) also increases, as supply device 1 allows for a high degree of prefabrication (approximately 90%).

[0036] The supply device 1 can be mounted on (house) walls and facades and can be positioned flush with, protruding from, or recessed from the facade 2. For this purpose, the supply device 1 has a housing 3 having fixing means with which a reversible connection to the (external) wall or facade 2 of the building / room can be established. As fixing means, the housing 3 can have holes, for example on the housing edge, through which screws can be passed, with which the housing 3 can be fixed to the facade 2 or an external wall. However, embodiments are also conceivable in which the housing 3 can be fixed to the facade 2 or external wall of the building 28 by snapping, hooking, or other techniques known to those skilled in the art.

[0037] Suitably, the supply device 1 itself is a facade part that is reversibly inserted into the outer wall / facade 2.

[0038] Suitably, the location of the facade 2 where the supply device 1 is to be reversibly fixed is appropriately prepared to receive the supply device 1, for example, by means of a recess in the facade 2, a support surface, or a frame into which the supply device 1 is fitted / placed. Furthermore, the facade 2 can have devices with which the supply device 1 is snapped, hooked, or screwed into or onto the facade / external wall 2.

[0039] At the points where the supply device 1 is fixed to the facade / exterior wall 2, and on the supply device 1 itself, interfaces or (quick) connectors are arranged, which are connected to each other when the device 1 is fixed to the facade / exterior wall 2. These interfaces / connectors connect, for example, power and / or control lines of the supply devices to the power / control network of the usage unit (an air conditioning system, a heat pump, and / or a hot water storage production system of the supply device 1) and to the refrigerant, air, water, and heating lines in the usage unit 27.

[0040] The housing 3 serves to accommodate supply units that, for example, serve to regulate the temperature (air conditioning) and / or ventilate (fan) of the usage unit 27. However, the supply unit can also be designed to accommodate a domestic hot water heat pump system for supplying the usage unit 27 with hot water.

[0041] Ventilation openings enable smooth operation, while inspection hatches facilitate easy maintenance, ensuring complete inspection of the installed supply units (systems). Supply device 1 ensures ideal supply and exhaust air routing, which is required for the efficient operation of the installed supply units.

[0042] The device 1 provides protection from environmental influences, visual protection from the side-mounted units 27, protection from unwanted noise emissions, and is modularly expandable. For this purpose, the housing 3 can be covered with slats 4 or other surfaces with air openings.

[0043] Housing 3 has at least one supply unit. One to three (self-sufficient) decentralized heating / cooling / service water ventilation systems can be accommodated per housing 3 (accommodating unit or technical unit), which, for example, draw renewable energy from the air.

[0044] The supply device 1 can be coupled and expanded as desired. The basic dimensions of the housing 3, for example, have a height of 250-280 cm, a width of 130-140 cm, and a depth of 70-90 cm, depending on the building height, the building axis, and the size of the supply unit.

[0045] A holder for a crane fork 10 or a crane eye (in the upper area of ​​the device 1) guarantees a smooth installation of the device 1 at the installation location on the facade 2.

[0046] The supply device 1 is fixed to the facade / exterior wall 2 of a building 28 and can be easily removed, relocated, or dismantled. This enables a quick replacement of an entire supply device 1. The supply device 1 simplifies the replacement of defective supply units or the installation of newer, more effective, or more environmentally friendly supply units thanks to the inspection opening(s) and inspection flap(s). This ensures that the building 28 is always equipped with the latest, most effective, and most environmentally friendly supply units.

[0047] The following technologies are intelligently integrated in the supply device 1 (for example): - one air-to-air heat pump or air-to-water heat pump per usage unit for heating and cooling the usage unit / room 27 to which the supply device 1 is attached, - an air-to-air condenser outdoor unit of the domestic hot water heat pump, - Supply and exhaust air connections for decentralized heat recovery ventilation 25 per unit 27 (with filters), - a heatable receiving device 18 for collecting condensate from the outdoor and indoor units (modularly expandable and merging), - a discharge unit with temperature-controlled regulation, - Inspection openings / hatches 22 for professional maintenance of the installed supply units (technical systems), - an emergency switch to switch off the supply units, - a switch box for connection to the power grid (for this purpose, the housing 3 may have an interface for connection to the power grid of the residential unit), - one or more sockets to facilitate maintenance, - a light switch and a light source to enable maintenance or troubleshooting at night or in poor visibility conditions, - at least one (quick) connection / (quick) connector (or one interface and / or plug connection) for the supply and control lines of the installed supply units for easy installation, effective maintenance and troubleshooting, - Brackets and holders for cables, condensate drains, pipe connecting lines, - a receiving device for the supply and exhaust air of the heat recovery ventilation unit, - Vibration dampers and sound decoupling brackets for the installed supply units, - Protective grilles to prevent animals from nesting, - ventilation openings, - Exhaust and supply air devices including brackets and holders, - Fixing means (fasteners) for fixing the supply device 1 to the facade 2, - intelligent routing of the room exhaust air within the supply device 1 in order to increase the efficiency of the system technology, and / or - Mounting for a crane fork / crane eye on the upper frame of the supply device 1

[0048] The supply device 1 is suitable for private or commercial use in a variety of usage units 27, such as in apartments, flats, student housing, micro-apartments, hotels, guest houses, kindergartens, schools, universities, barracks, hospitals, nursing homes and retirement homes.

[0049] Fig. 1 shows a housing (or a basic module) 3 of a supply device 1 for a technical unit as a view (left) and as a section (right) as well as the floor plan of the housing 3 (top).

[0050] In the in the Fig. In the embodiment of the supply device 1 shown in Figure 1, the housing 3 comprises a base plate 5 and a ceiling plate 6, which are spaced apart by laterally arranged struts / supports 7 (which can also be found in the corners of the supply unit); the height is arbitrary and depends on the respective building. On the facade side, there is another strut 7, which has a bore 8 for receiving fixing means, such as screws, with which the housing 3 can be screwed to the facade / exterior wall 2 of a building 28.

[0051] Fig. 2 shows three-dimensional representations of the housing 3 of the supply device 1 from the side facing away from the facade (a) and from the side facing the facade (b).

[0052] Fig. Figure 3 shows a further embodiment of the housing 3 of the supply device 1 for two technical units. In this embodiment, the housing 3 has an intermediate floor 9. This intermediate floor 9 serves as a floor for another technical unit or for accommodating additional supply units and their supply connections.

[0053] Of course, further embodiments of the housing 3 are also conceivable, in which the housing 3 has more than one intermediate floor 9.

[0054] Fig. 4 shows the Fig. 3 shows the embodiment of the housing 3 with an intermediate floor 9 from the side facing the facade 2 (a) and from the side facing away from the facade 2 (b).

[0055] Fig. 5 shows the Fig. 3 and Fig. 4 shows the embodiment of the housing 3 with the supply units arranged in the housing 3 and their supply connections.

[0056] The Fig. Figure 5 shows a floor plan of the supply device 1 with supply units and supply connections. On the left side of the Fig. 5 shows a section along line AA through the supply device 1 and on the right side a section along line BB.

[0057] The Fig. 5 shows an example arrangement of the supply units and supply connections.

[0058] Devices for crane transport (crane hooks 10) are arranged on the cover plate 6, which facilitate the transport to the installation location of the supply device 1.

[0059] The side walls of the housing 3 have an outer panel 23 with air openings for the supply units, for example, louvers 4, as well as protective grilles 12 to prevent animals from nesting. The openings for the inlet and outlet ducts 11 serve to ventilate and extract the room air of the utilization unit 27 and are equipped with filters. The room air can also be used for heat recovery.

[0060] In the in the Fig. In the embodiment of the supply device 1 shown in Figure 5, a control cabinet 13 with an emergency switch, socket(s), light switch(es), and a connection to the power grid are arranged in the housing 3. In addition, the supply device 1 comprises a supply unit for heating and cooling, which is mounted on vibration dampers 15, a (box) interior lighting 16, a connecting part 17 for the optimized exhaust air flow of the supply unit and a heatable and temperature-controlled tray 18 for collecting condensate, as well as a downpipe 19 for condensate and at least one connection or quick-release coupling 20 for power and control lines, supply and return of the refrigerant and condensate to the supply unit (indoor unit 24) in the room.

[0061] The supply unit draws in ambient air on the facade side through the air-permeable outer cladding 23 of the housing 3 and expels it (through the connecting part 17) in the direction away from the facade. For this purpose, the supply unit is positioned at a distance from the facade 2.

[0062] The quick couplings 20 connect the supply unit to the supply lines (control and power lines, flow and return of the refrigerant and condensate) which lead inwards to the supply unit of the usage unit 27 (indoor unit 24).

[0063] Fig. 6 shows the Fig. 5 shows the embodiment of the supply device 1 from the facade side (a) and from the side facing away from the facade 2 (b) with external cladding 23.

[0064] Fig. Figure 7 shows a floor plan of a residential unit 27 in which a supply device 1 is arranged on the exterior wall 2. Accessible from the balcony 21 of the residential unit 27, the housing 3 of the device 1 has an inspection flap 22.

[0065] Supply and exhaust air ducts 26, which are connected to the heat recovery ventilation system 25, run through openings in the facade / outer wall 2. The supply and exhaust air openings 11 ensure efficient operation of the supply unit (the outdoor unit 14). The supply unit is connected to one or more indoor units 24 for heating, cooling, and air purification via ducts 31 and interface 20. The supply device 1 is connected to one or more ventilation units 25 with heat recovery and filters for the supply and exhaust air. To connect the supply device 1 to the ventilation units with heat recovery 25, the supply and exhaust air supply ducts 26 are (reversibly) connected to the supply connections on the supply device 1.

[0066] The indoor unit 24 for heating and cooling and air purification is part of a hermetically sealed coolant circuit in which a coolant is heated or cooled by the outdoor unit 14 and pumped through supply lines 31 to one or more indoor units 24.

[0067] Room ventilation is provided by the heat recovery ventilation unit 25, which has supply air and exhaust air connected via supply ducts 26. This ventilation system can supply and regulate several rooms simultaneously, preventing mold and moisture. For this purpose, the heat recovery ventilation unit 25 is equipped with filters that filter the air. Furthermore, the heat absorbed from the used exhaust air can be transferred to the cold outside air or vice versa. This heated or cooled supply air is then supplied to the rooms via a duct system (supply ducts 26).

[0068] Furthermore, the supply unit (the outdoor unit 14) can be used to heat the water in the usage unit 27, so that the usage unit 27 itself only needs to provide electricity, water (cold fresh water) and waste water.

[0069] Fig. 8 shows the arrangement of a plurality of supply devices 1, which serve for the decentralized supply of a plurality of usage units 27 of a building 28.

[0070] The downpipes 19 of the housings 3 are connected to each other so that the condensate is led through several housings 3 into the sewage system of the building.
