Description

[0001] The invention relates to a housing for accommodating components and a system for supplying energy and / or ventilating a building. State of the art

[0002] When modernizing buildings to improve their energy performance, especially when converting a building to a low-energy or zero-energy building, it is usually necessary to expand or install new thermal insulation, a heating system, a ventilation system, an air conditioning system, a photovoltaic system, or a solar thermal system. This is difficult and time-consuming. Installing the new components required and the necessary air, water, and fuel lines often requires extensive construction work and structural modifications to the building. Disclosure of the invention Advantages

[0003] According to the present invention, a housing for accommodating components having the features of claim 1 is proposed.

[0004] Furthermore, according to the invention, a system for energy supply and ventilation of a building with the features of claim 14 is proposed.

[0005] Preferred embodiments of the housing and the system are defined in the subclaims. According to the invention, the system comprises at least two components of an energy supply system and / or ventilation system for a building, as well as a housing for accommodating the at least one component, wherein the at least one component is operable in the housing. According to the invention, the housing can be mounted outside the building. The term "energy supply system" refers to a system comprising at least one device intended to supply energy to a building and / or to remove energy from the building. The energy can be, in particular, thermal energy and / or electrical energy or electric current. The thermal energy can be transported, in particular, convectively with the aid of air and / or water and / or a heat transfer medium and / or a coolant.According to the invention, the energy supply system comprises a heating system, a solar thermal system, an air conditioning system, or a photovoltaic system. Certain components can be assigned to several different systems; for example, a heat pump can be assigned to both a ventilation system and a heating system. Therefore, the general term "energy supply system" is used.

[0006] A "ventilation system" is understood to mean a system comprising at least one device for ventilating and / or de-ventilating a building or a part of a building. In particular, a ventilation system is intended to supply fresh air to a building. A ventilation system is intended, in particular, for ventilating a building or for exchanging air within a building. A ventilation system may also include a component designed to recover heat from exhaust air. For example, the ventilation system may include a heat exchanger in which part of the thermal energy of the exhaust air is transferred to the supplied fresh air. A ventilation system may also include a heat pump for recovering heat from exhaust air.

[0007] A "heating system" is understood to mean a system comprising at least one device for generating and / or receiving thermal energy, in particular a heating device or heating burner, for example a condensing boiler, particularly for use in building heating and / or for generating hot water, preferably by burning a gaseous or liquid fuel or by electrical heating. A heating system can also consist of several such devices for generating thermal energy as well as other devices supporting heating operation, such as a water or fuel storage tank, a water or fuel pump, or an expansion tank. A heating system should also be understood to mean a heat pump heating system, which uses thermal energy from the environment, particularly for heating the building.A heating system is understood to mean devices for utilizing geothermal energy, in particular with the help of geothermal probes or geothermal collectors, and / or outside air and / or exhaust air and / or wastewater. Examples of components of a heating system are a heat pump for a geothermal system or an outdoor unit of a heat pump and / or an indoor unit of a heat pump for extracting heat from the outside air. The thermal energy obtained with a heat pump can, for example, be used to heat domestic water and / or heating water. A component of a heating system is also understood to mean a device for utilizing district heating. For example, a component of a heating system can be a heat exchanger for utilizing district heating.

[0008] The term "air conditioning system" refers to a system comprising at least one device for generating and / or ensuring a desired indoor air quality in a building or part of a building. In particular, an air conditioning system can regulate temperature and / or humidity. Examples of components of an air conditioning system include an air conditioning system and / or a chiller and / or an outdoor unit or indoor unit of a decentralized air conditioning system. A heat pump or heat pump heating system operated in reverse for cooling is another example of a component of an air conditioning system.

[0009] A "photovoltaic system" is understood to mean a system comprising at least one device for converting sunlight or ambient light into electrical current.

[0010] Examples of components of a photovoltaic system are a solar cell, a power storage device, in particular an accumulator, a charge controller, a solar inverter or an inverter for converting direct current into alternating current or a device for feeding power into the power grid.

[0011] A "solar thermal system" is understood to mean a system consisting of at least one device for generating heat from sunlight or ambient light. Examples of components of a solar thermal system include a solar collector, a pump or pump system for a heat transfer medium, a heat exchanger, or a storage or tank for the heat transfer medium.

[0012] A "housing" is understood to mean a solid, largely dimensionally stable shell that largely protects the at least one component from environmental influences, in particular from rain, snow, wind, and / or extreme temperatures. The housing can, for example, be made at least partially of metal. Elements for securing the at least one component are preferably located within the housing. A housing height is preferably greater than a base area of ​​the housing or than a diameter of a base area of ​​the housing. A heating system, ventilation system, air conditioning system, photovoltaic system, and / or solar thermal system of the building can be largely fully operated with components accommodated in the housing.

[0013] The system makes it possible to modernize a building particularly easily and quickly to improve its energy performance. Housing components of a building's energy supply system and / or ventilation system in a single enclosure allows for quick and cost-effective installation. Structural work on the building is largely unnecessary. The system has the additional advantage that the required components do not require any space within the building.

[0014] The features listed in the subclaims enable advantageous further developments of the system.

[0015] The system is particularly advantageous when the energy supply system includes a heating system and / or an air conditioning system. Heating and air conditioning systems can require a lot of space and / or generate noise, at least occasionally. This increases living comfort in the building.

[0016] According to the invention, the housing can be attached to an exterior wall of the building, particularly by means of a screw connection. This has the advantage that the system or housing can be installed particularly stably. Potential wind influences on the housing are reduced. This ensures safe and trouble-free operation of the system.

[0017] The system is particularly convenient to operate if it has a modular design. If, in particular, at least one component has a modular design, then at least one component can be easily replaced or attached within the housing. "Modular design" or "modular construction" should be understood to mean that at least one component intended for installation in the housing has a standardized or specified design and / or geometry and / or standardized or specified connections and / or fastening means, so that it fits into the housing and, if necessary, can be connected and / or attached within the housing. The at least one component with a modular design can be accommodated or attached within the housing at virtually any desired height or position.

[0018] A modular system allows the system to be adapted to technical requirements by selecting suitable components from a set of at least two components. For example, the housing can contain a solar inverter if the building includes a solar cell. If the building has a solar collector instead of a solar cell, the housing can contain a pump system for a heat transfer medium of the solar thermal system instead of the solar inverter. A modular system has the additional advantage that it can be easily retrofitted or upgraded at any time. This means that the system's performance can be improved; for example, a condensing boiler can be replaced with a new, more efficient condensing boiler; and / or the system's range of functions can be changed; for example, a condensing boiler can be exchanged for components of a photovoltaic system.

[0019] If the housing has a base area dimensioned such that a component base area of ​​the at least two components can be covered by the base area (72), this has the advantage that the at least two components can be accommodated largely completely within the housing. In this way, the at least two components are particularly well protected from external influences. The fact that the component base area can be "covered" by the base area means that an arrangement of the components exists in which the component base area, or a projection of the component base area onto the base area of ​​the housing, is located entirely within the base area.

[0020] If the housing has a largely rectangular footprint, where the housing is designed to be arranged along the width of a building largely parallel to an outer wall of the building, this has the advantage that the at least two components fit particularly well into the housing. This enables the use of standard components of an energy supply system and / or ventilation system for a building, which usually have a largely rectangular component footprint. If the housing width is at least 1.1 times the housing depth, this enables a wind-stable or wind-insensitive housing geometry, particularly if the housing is enclosed in a thermal insulation layer of the building. If the housing width is at most 0.9 times the housing depth, this has the advantage that the at least two components and the piping or lines required for their operation can be arranged particularly conveniently in the housing.If at least two components have a largely square component base area or a component width that is greater than a component depth, the components can be installed particularly space-efficiently.

[0021] For example, the at least two components can be mounted in a front area of ​​the housing and the piping or lines can be mounted in a rear area.

[0022] The designations or position specifications "front," "rear," "left," "right," "bottom," and "top" in this document refer to a designated standard position of the housing relative to the building. Rear refers to an area of ​​the housing near a rear housing wall. A "rear housing wall" or rear housing wall refers to a housing wall of the housing that is closest to the building; in particular, the "rear housing wall" refers to the housing wall that abuts the building. Front refers to an area of ​​the housing opposite the rear area or an area of ​​the housing near a front housing wall. A "front housing wall" or end face of the housing refers to a housing wall of the housing that is opposite the rear housing wall. The front housing wall and the rear housing wall are preferably arranged largely parallel to one another.

[0023] Left refers to an area of ​​the enclosure that is located on the left side when the front or front housing wall is viewed from the front. In the left area of ​​the enclosure, there is a "left housing wall" of the enclosure. Right refers to an area of ​​the enclosure that is located on the right side when the front or front housing wall is viewed from the front. In the right area of ​​the enclosure, there is a "right housing wall" of the enclosure. The right housing wall and left housing wall are "side housing walls."

[0024] In this document, "depth" refers to a length in the front-to-rear direction. If the rear enclosure wall lies largely in one plane, the depth is perpendicular to this plane or to the rear enclosure wall. The depth can alternatively be defined perpendicular to the front enclosure wall and / or parallel to the right enclosure wall and / or parallel to the left enclosure wall and / or perpendicular to the exterior wall of the building. "Width" in this document refers to a length that is largely perpendicular to the depth and largely perpendicular to the height.

[0025] If a housing height of the housing is greater than a component height or standard component height of the at least one component, this has the advantage that the at least two components can be accommodated largely completely within the housing.

[0026] In this way, the at least one component is particularly well protected from external influences. According to the invention, the housing height or standard component height is between 2 and 6 times, in particular approximately 2.5 times, the component height. This has the advantage that multiple components can be mounted one above the other in the housing.

[0027] A "standard component height" is a defined length that relates to the height of at least one component. For example, the standard component height can be a predetermined height that the at least one component must largely have and / or not exceed. It is also conceivable for at least one component to have a component height that is largely equal to a multiple of the standard component height and / or that the component height is largely equal to an integer multiple of a predetermined fraction of the standard component height, for example, a quarter of the standard component height. The standard component height or a relationship between the component height and the standard component height enables a modular design of the system or the at least one component.

[0028] If the housing height largely corresponds to the building's height or depends on the building's height, this has the advantage of making the system particularly easy to connect to all floors of the building. In particular, cables from the building can be routed directly into the housing.

[0029] According to the invention, the housing has a rail system that runs largely along the height of the housing for attaching the at least one component. This enables a particularly simple and user-friendly implementation of a modular structure. Because the rail system runs largely along the height of the housing, a particularly precise adjustment of the height at which a component is mounted is possible. This enables efficient use of space within the housing.

[0030] A bracket that can be attached to the rail system and to which at least one component can be attached, particularly for a modular component, allows the use of standard components that do not need to be adapted to the rail system. This makes the system particularly flexible and can be extensively equipped.

[0031] If the rail system has mounting holes for attaching the holder and / or the at least one component, the holder or the at least one component can be attached particularly securely. At least one component can be attached to at least one mounting hole, preferably to at least two mounting holes. It is conceivable for at least one component to be screwed, plugged, clipped, and / or suspended from the mounting holes.

[0032] If the housing is at least partially thermally insulated, particularly in a sandwich construction, the at least two components can be particularly well protected against temperature fluctuations. This allows components intended for indoor use to be used in the system. If the housing is enclosed in a thermal insulation layer of the building, this also enables good thermal insulation of the building. It is conceivable, for example, that the thermal insulation is attached in such a way that at least one component is not protected by the thermal insulation. This can be advantageous, for example, for an outdoor unit of a heat pump and / or an air conditioning system.

[0033] If the housing has at least one opening and / or at least one connection for at least one line which connects the at least one component to the building, for example a line for an air supply and / or at least one outlet for air and / or a power line and / or a water line and / or a fuel line, this has the advantage that the system can be installed on the building particularly easily. This can speed up the installation process and make it less prone to errors. The opening is in particular an opening on a side of the housing which is connected to the building, preferably the rear housing wall. Preferably, the building or a wall of the building has suitable openings at the corresponding locations.For example, the opening may be a vent for an air conditioning or ventilation system for introducing and / or discharging air into an adjacent room of the building or an opening for the passage of wires, pipes or cables.

[0034] If the housing has a shaft that runs largely along the housing height, particularly within the housing, this enables particularly efficient and secure installation of lines or pipes, and in particular cables. The shaft can be located inside or outside the housing. For example, the shaft can be formed by a sheet metal that is arranged parallel to the rear of the housing or rear housing wall and is attached to the two adjacent sides of the housing, dividing the housing into two spatial areas largely separated by the sheet metal. The shaft can be a pipe that runs along the housing height.

[0035] If the shaft has a shaft depth corresponding to one-fifth to one-third, preferably substantially one-quarter, of the housing depth, the housing is particularly strongly reinforced. This is particularly advantageous if the shaft rests against, or is attached and / or fastened to, the housing wall of the housing along the shaft depth, which runs along the housing depth. In preferred embodiments, the shaft is attached within the housing to at least one of the side housing walls or to the right housing wall and / or left housing wall.

[0036] If the housing has a holding device for securing at least one line, for example an air line and / or a power line and / or a water line and / or a fuel line, in particular by snapping and / or clipping, the at least one line is securely, clearly, and stably mounted. This is particularly advantageous during maintenance work and / or system expansions.

[0037] A valve, in particular a safety valve, for at least one line, in particular a water line and / or heat transfer line and / or fuel line, has the advantage that one or more of the at least two components can be replaced and / or maintained particularly easily. In particular, the building does not need to be entered to perform maintenance or replace a component. For example, lines for a gas supply and for domestic and heating water can be closed from the housing using the corresponding valves. For example, a repair to the condensing boiler can be carried out directly on the housing.

[0038] If the housing has at least one opening for exhaust air and / or exhaust gases and / or fresh air, the system can be installed even more easily. For example, it is not necessary to channel the exhaust gases into a chimney located in the building. The opening can be an opening leading to the outside, which is preferably attached to a housing wall that is not in contact with the building, for example on the underside of the housing or lower housing wall or top side of the housing or upper housing wall or front side of the housing or front housing wall. An opening leading to the outside can, for example, be a chimney for discharging the exhaust gases from a condensing boiler and / or a grille opening for drawing in fresh air for a ventilation system and / or for discharging used air and / or for a heat pump.

[0039] The system is further improved if the housing has at least one drain, particularly for rainwater and / or wastewater and / or condensate. A drain is understood to be a pipe or pipe system that directs rainwater and / or wastewater and / or condensate from the housing, for example, into a building's drainage system. This allows unwanted water to be removed from the housing, for example, water that has penetrated the housing during maintenance during rain.

[0040] This enables safe and trouble-free operation of the system. Preferably, the drain directs rainwater and / or wastewater and / or condensate out of the bottom of the housing.

[0041] A drain can also conduct rainwater and / or wastewater and / or condensate through the building. For example, wastewater from each floor of the building can be directed into the housing's drain. This has the advantage that no central, vertical drain line needs to be installed in the building. It is also conceivable for water collected in a gutter on the roof of the building to be directed through the housing's drain into the drainage system and / or into a water reservoir arranged next to the housing and / or in the housing. In particular, one or the shaft of the housing can have a drain or be connectable to a drain. If the housing has at least one openable and closable cover device for at least one opening in the housing, for example a flap, in particular a door, the maintenance, care, repair, testing or upgrading of the system is simplified.

[0042] Preferably, the cover device and the corresponding opening in the housing are arranged in such a way that access to the components that require regular inspection and maintenance, for example changing air filters in the ventilation system, is guaranteed. Preferably, the cover device and the corresponding opening in the housing are arranged in such a way that a valve, in particular a safety valve, is particularly easy and quick to access. In the event of a malfunction in the system, the system can be separated from the building quickly and easily. This increases the safety of the system. Preferably, the cover device is sealed watertight and / or windtight. In this way, the at least two components are protected when the cover device is closed, in particular from environmental influences. Preferably, the cover device has thermal insulation, in particular in a sandwich construction. In this way, the at least two components are protected from temperature fluctuations.If the housing is enclosed in a thermal insulation layer of the building, this also enables good thermal insulation of the building. Preferably, the at least one opening or the at least one covering device is located on the front side of the housing or on the front housing wall.

[0043] The present invention also discloses a housing for accommodating the at least two components of an energy supply system and / or ventilation system for a building.

[0044] The housing is intended for use in a system according to the preceding invention. It is intended that the at least two components are operable within the housing. The housing is mountable outside the building.

[0045] The housing according to the present invention provides the additional advantage of reducing noise pollution from the energy supply system and / or ventilation system in the building. Because the at least two components can be operated in the housing, which is located outside the building, the noise emissions of the at least one component in the building are significantly reduced. This is particularly advantageous for the outdoor unit of the heat exchanger and / or for a heat recovery unit of the ventilation system. These components may include a compressor, which can generate disruptive noise emissions. Drawings

Description

[0047] In the different versions, identical parts have the same reference numbers.

[0048] Figures 1 and 2 show an embodiment of a system 10 for energy supply and ventilation of a building 12. Figure 3 shows a section through System 10. System 10 is installed outside Building 12. Figure 3 schematically shows lines 13 which connect the system 10 to the building 12.

[0049] The system 10 comprises a ventilation heat pump 14. The ventilation heat pump 14 is mounted in a housing 15. The ventilation heat pump 14 is a component 17 of a ventilation system of the building 12. The ventilation system is part of an energy supply system. The ventilation heat pump 14 is intended to recover thermal energy from exhaust air 16 from the building 12 and to make it available for heating domestic water and / or heating water for a building heating system. The system 10 is connected to domestic water lines 18 and heating water lines 20. The domestic water lines 18 have at least one supply line for supplying domestic water from the building 12 to the system 10 and at least one discharge line for discharging domestic water from the system 10 into the building 12.The heating water lines 20 comprise at least one supply line for supplying heating water from the building 12 to the system 10 and at least one discharge line for discharging heating water from the system 10 into the building 12. In the exemplary embodiment, exhaust air 24a from a first floor of the building 12, exhaust air 24b from a second floor, and exhaust air 24c from the rear of the building are supplied to the system 10 via ventilation lines 22. The ventilation heat pump 14 is supplied with electrical energy from the building 12 via a power line 36. The ventilation heat pump 14 can be operated largely entirely within the housing 15.

[0050] The system 10 includes a solar inverter 30. The solar inverter 30 is mounted in the housing 15. The solar inverter 30 is a component 17 of a photovoltaic system of the building 12. The photovoltaic system is part of the energy supply system. The photovoltaic system has a solar cell (not shown) on a roof 32 of the building 12. The solar cell is connected to the solar inverter 30 of the system 10 via a photovoltaic power line 34. The solar inverter 30 is provided to convert a direct current provided by the solar cell into an alternating current. The alternating current is fed into the building 12 via a power line 36. The power line 36 is connected to an electricity meter box 38 in the building 12. The alternating current provided by the solar inverter 30 can be used to operate electrical devices in the building 12.In alternative embodiments, it is conceivable that the power generated by the solar inverter 30 is made available to the components 17 of the system 10, for example the ventilation heat pump 14. The solar inverter 30 can be operated largely in its entirety in the housing 15.

[0051] The system 10 comprises a gas condensing boiler 40. The gas condensing boiler 40 is mounted in the housing 15. The gas condensing boiler 40 is a component 17 of a heating system of the building 12. The heating system is part of the energy supply system. Fuel gas is supplied to the gas condensing boiler 40 via a gas line 42 from the building 12. By burning the fuel gas, the gas condensing boiler 40 generates heat energy, which can be used to heat domestic water or heating water. In the exemplary embodiment, it is provided that a basic heat requirement for the domestic water or heating water can be covered by the ventilation heat pump 14. An additional heat requirement for the domestic water or heating water can be generated, if necessary, by the gas condensing boiler 40. A domestic water system orThe heating water system is connected to the ventilation heat pump 14 and the gas condensing boiler 40 via internal lines 44 located in the housing 15. The gas condensing boiler 40 is supplied with electrical energy from building 12 via the power line 36. The gas condensing boiler 40 can be operated largely in its entirety within the housing 15.

[0052] The system 10 includes an expansion tank 46. The expansion tank 46 is mounted in the housing 15. The expansion tank 46 is a component 17 of the heating system of the building 12. The expansion tank 46 is provided for pressure equalization of the domestic water or heating water. This prevents damage to the pipes 13 or domestic water pipes 18 or heating water pipes 20 and / or corresponding safety valves. The expansion tank 46 can be operated largely to its full extent within the housing 15.

[0053] The housing 15 is located outside the building 12. In the exemplary embodiment, the housing 15 is attached to an exterior wall 48 of the building 12. The housing 15 is secured to the exterior wall 48 using screw connections 50.

[0054] In Figure 1 or Figure 2 the housing 15 is shown in an open state. The Figure 4 shows the closed housing 15 from the front. Figure 5 shows a perspective view of a variant of the housing 15. It is intended that the system 10 is typically operated with a closed housing 15. The housing 15 can be fully or partially opened, for example, for inspections and / or repairs and / or for upgrading or converting the system 10.

[0055] The system 10 has a modular design. The components 17 installed in the housing 15 have a modular construction. In the exemplary embodiment, the components 17 are the ventilation heat pump 14, the solar inverter 30, the gas condensing boiler 40, and the expansion tank 46. The housing 15 is largely cuboid-shaped. The housing 15 is largely hollow on the inside so that the components 17 can be accommodated inside. The components 17 can be fastened in the housing via a rail system 58. The components 17 have suitable means for fastening to the rail system 58. The components 17 can be arranged as desired in the housing 15, in particular with regard to the spatial position of the component 17. The rail system 58 allows the height at which a component 17 is mounted to be largely freely selected. The lines 13 running in the housing can be adapted to virtually any arrangement of the components 17.The arrangement of components 17 in the exemplary embodiment is selected such that components 17 requiring regular maintenance and / or inspection are particularly easy to reach. Furthermore, it is advantageous if components 17 with a high weight are arranged lower than lighter components 17. This increases the mechanical stability of system 10. This makes system 10 particularly secure.

[0056] Due to the modular design of the system 10, the positions of components 17 can be interchanged. A component 17 can also be replaced by another component 17. Figures 6 and 7 show an alternative embodiment of the system 10. The system 10 of the Figures 6 and 7 The variant shown has the same housing 15 as the system 10 of the Figures 1 , 2 and 3The system 10 of the illustrated embodiment. Figures 6 and 7 The variant shown has different components 17 than the system 10 of the Figures 1 , 2 and 3 The example shown in the Figures 6 and 7 The housing 15 shown comprises an outdoor unit 60 of an air-water heat pump 62, an indoor unit 64 of an air-water heat pump 62, a solar inverter 30, a ventilation unit 66 and water storage 68. The use of other components 17 than in the exemplary embodiment is in the Figure 6 The variant shown is possible due to the modular design of the system 10.

[0057] In particular embodiments, it is conceivable for the housing 15 to have at least one mounting block or a quick-assembly system to which the at least one component 17 can be connected particularly quickly. A mounting block has all the connections or lines 13 necessary for the operation of the component 17, in particular power lines 36, as well as means for fastening the component 17.

[0058] The Figure 6The system 10 shown comprises the air-to-water heat pump 62. The air-to-water heat pump 62 is a component 17 of the heating system of the building 12. The air-to-water heat pump 62 is intended to extract thermal energy from the ambient air and use it to heat the domestic water or heating water. The air-to-water heat pump 62 has an outdoor unit 60 and an indoor unit 64. The outdoor unit 60 is arranged in an upper region of the housing 15. The housing 15 has an opening grille 70 in the region of the outdoor unit 60. The outdoor unit 60 is supplied with outside air through the opening grille 70. The outdoor unit 60 is intended to extract thermal energy from the ambient air.

[0059] In the example and in the Figure 6 In the variant shown, there is an opening grille 70 on a housing front side 26 and an opening grille 70 on a right housing side 27 (see Figures 3 and 4for definitions of the position information relative to the housing 15). In variants, the arrangement of the opening grille 70 is based on the technical requirements, in particular on a position of an aerial photograph of a component 17 arranged near the opening grille 70. For example, it is possible that the housing front 26 and / or the right housing side 27 and / or a left housing side 28 and / or a housing top 31 have at least one opening grille 70. In Figure 5 an alternative embodiment is shown in which the housing 15 does not have opening grilles 70.

[0060] The outdoor unit 60 is connected to the indoor unit 64 via internal lines 44 of the housing 15. The outdoor unit 60 transmits the thermal energy to the indoor unit 64 via an internal line 44. The indoor unit 64 is arranged in a lower region of the housing 15. The indoor unit 64 is designed to transfer the thermal energy to the domestic hot water or to the heating water. The indoor unit 64 is connected to the domestic hot water line 18 and to the heating water line 20. The air-water heat pump 62 is supplied with electrical energy from the building 12 via the power line 36. The air-water heat pump 62 can be operated largely to its full extent within the housing 15.

[0061] The indoor unit 64 is connected to the water tank 68 via the internal lines 44. The water tank 68 is a buffer tank. The water tank 68 improves the efficiency of the heating system. The water tank 68 stores warm water for the heating system or for the domestic hot water system. The water tank 68 ensures a fast and reliable hot water supply. In this way, the system 10 can provide hot domestic hot water and / or heating water almost immediately.

[0062] The Figure 6The system 10 shown comprises the ventilation unit 66. The ventilation unit 66 is a component of the ventilation system of the building 12. The ventilation unit 66 is intended to recover heat energy from the exhaust air 16 from the building 12 and to make it available for heating fresh air 69 supplied to the building 12. The system 10 is connected to the ventilation ducts 22 of the building. The exhaust air 16 from the building 12 is fed into the ventilation unit 66 via the ventilation ducts 22. The ventilation unit 66 has a heat exchanger which transfers the heat energy of the exhaust air to the sucked-in fresh air 69. The fresh air 69 heated in the ventilation unit 66 is supplied to the building 12 via the ventilation ducts 22.

[0063] In Figure 8 An empty, open housing 15 without components is shown. Figures 9 and 10show the empty, closed housing 15 in a view from the front ( Figure 9 ) or from the right side ( Figure 10 ). Figure 11 shows a horizontal section in a lower part of the housing 15 along line XI-XI in Figure 9 The housing 15 has a largely rectangular base area 72. In the exemplary embodiment, the components 17 each have a component base area that fits into the base area 72. The components 17 can be completely accommodated in the housing 15.

[0064] The housing 15 is aligned along the housing width 54 largely parallel to the outer wall 48 of the building 12. In the exemplary embodiment, the housing width 54 is 90 cm. The housing depth 52 is 80 cm. In the exemplary embodiment, the housing width 54 is 1.125 times the housing depth 52. In alternative embodiments, the ratio of the housing width 54 to the housing depth 52 is between 1.1 and 1.5, preferably between 1.15 and 1.25, particularly preferably largely 1.2. In further embodiments, the ratio of the housing width 54 to the housing depth 52 is between 0.5 and 0.9, preferably between 0.75 and 0.55, particularly preferably largely 0.8. It is conceivable that in these embodiments the components 17 are arranged in at least two rows. A first row is arranged in the front region of the housing 15, a second row is arranged in the rear region of the housing 15. For example, low-maintenance ormaintenance-free components 17 are arranged in the rear area of ​​the housing 15.

[0065] In the exemplary embodiment, the housing width 54 is 90 cm. In the exemplary embodiment, the housing depth 52 is 80 cm. In alternative embodiments, the housing width 54 of the housing 12 and / or a housing depth 52 of the housing 12 is between 60 cm and 120 cm, preferably between 75 cm and 105 cm, particularly preferably between 85 cm and 95 cm. If the housing width 54 of the housing 15 and / or the housing depth 52 of the housing 15 is between 60 cm and 120 cm, preferably between 75 cm and 105 cm, particularly preferably between 85 cm and 95 cm, a particularly favorable ratio of housing volume to housing surface is possible in this way, so that the housing 15 is particularly wind-stable or wind-insensitive. In addition, the at least one component 17 accommodated in the housing 15 is particularly well thermally protected in this way.

[0066] The housing depth 52 and / or housing width 54, or the ratio of the housing width 54 to the housing depth 52, is advantageously selected such that virtually all of the intended components 17 and cables 13 can be accommodated in the housing. In particular, the selection of the housing width 52 and / or housing depth 54 is based on the dimensions or external dimensions of the components 17.

[0067] A housing height 56 ​​of the housing 15 is 500 cm in the exemplary embodiment. In alternative embodiments, the housing height is between 400 cm and 600 cm, in particular approximately 500 cm. If the housing height 56 ​​is between 4 meters and 6 meters, in particular approximately 5 meters, two to four standard components 17 can be mounted in the housing 15. This enables comprehensive energy supply and ventilation of the building 12. A housing 15 with such a housing height 56 ​​has the additional advantage that it can be used in buildings 12 with two or more floors.

[0068] The housing depth 52 or the housing width 54 are each significantly smaller than the housing height 56. In the exemplary embodiment, the ventilation heat pump 14 has a component height of 110 cm. In the exemplary embodiment, the ventilation heat pump 14 is the largest component 17. The housing height 56 ​​is approximately 4.5 times the component height. In alternative embodiments, the ratio of the housing height 56 ​​to the component height is between 1.5 and 6, in special embodiments between 2 and 5, particularly preferably substantially 2.5.

[0069] The housing height 56 ​​of the housing 15 is determined by the height of the building 12. In preferred embodiments, the housing height 56 ​​largely corresponds to a height of the outer wall 48. Advantageously, the housing height 56 ​​is selected such that the housing 15 is located largely below the roof 32 of the building 12. In buildings 12 with a flat roof 32, the housing height can largely correspond to the height of the building 12. In Figure 3A building 12 with a sloping roof 32 is depicted. The housing 15 ends below the roof 32 or below an eave of the roof 32. The housing height 56 ​​largely corresponds to the height of the exterior wall 48. In alternative variants, the housing height 56 ​​is selected to be greater than the height of the building 12 and / or the roof 32 and / or an eave of the roof. In particular, the housing height 56 ​​can be selected such that a component 17 is located completely or at least partially above the building 12 and / or above the roof 32. This enables better noise protection. Noise emissions from the component 17 arranged at the top of the housing are no longer as noticeable in the building 12.

[0070] In the exemplary embodiment, the housing 15 is enclosed in an outer cladding 74 of the building 12 (see Figure 11). Between the outer wall 48 of the building 12 and the outer cladding 74, an insulation material (not shown) is attached for thermal insulation of the building 12. In this way, buildings can be renovated to improve energy efficiency. During renovation, insulation material is attached to an outer wall 48 and covered with an outer cladding 74. In the exemplary embodiment, the outer cladding 74 is at a distance of an insulation layer depth 76 from the outer wall 48. In the exemplary embodiment, the insulation layer depth 76 is 28 cm. In preferred embodiments, the insulation layer depth 76 is 0.2 times to 0.5 times the housing depth 52, particularly preferably 0.3 times to 0.4 times the housing depth 52. In this way, the part of the housing 15 protruding from the outer cladding 74 is particularly stable against the effects of wind.

[0071] In the exemplary embodiment, the components are mounted in the housing 15 using a rail system 58. Figure 13shows a view of a section of the opened housing 15, which has only a solar inverter 30 as a component. To better visualize the rail system 58, Figure 13 Only the left half of the housing 15 is shown, the rail system 58 is shown in its entirety. The rail system 58 consists of two rails 78. The rails 78 have a largely square cross-section. The rails 78 are attached to the right housing side 27 and the left housing side 28, respectively (see also Figure 11 ). The rails 78 have mounting holes 80. The mounting holes 80 are aligned with the front of the housing 15 or the front side 26 of the housing. This allows for particularly convenient mounting of the components to the rail system 58.

[0072] The solar inverter 30 is attached to the rail system 58 by means of a bracket 82. In the exemplary embodiment, the bracket 82 is largely made of bent or folded sheet metal. The geometry of the bracket 82 is selected such that a component 17 can be inserted into the bracket 82. The bracket 82 has a bracket depth 90. In the exemplary embodiment, the bracket depth 90 is 20 cm. The bracket depth 90 is advantageously based on the depth of the component 17 to be accommodated. It is particularly advantageous if the bracket depth 90 is selected such that a component 17 can be mounted as close as possible to the housing front 26 or to an opening in the housing 15. In this way, the component 17 can be operated and / or maintained particularly conveniently. This has the additional advantage that there is sufficient space for cables 13 or internal cables 44 in an area behind the bracket 82 in the housing 15.The holder 82 has a holder height 92. In the exemplary embodiment, the holder height 92 is 40 cm. The holder height 92 is advantageously based on the height of the component 17 to be accommodated. Preferably, the holder height 92 corresponds to the component height.

[0073] The solar inverter 30 has a Figure 13 invisible wall bracket. The wall bracket is intended for attaching the solar inverter 30 to a wall, preferably within a building. In the exemplary embodiment, the wall bracket has receptacles for screws so that the component 17 can be screwed to the wall. The bracket 82 has fastening openings 85 on its rear side 84 that match the wall bracket so that a component 17 can be screwed to the bracket 82. Figures 17 and 18An alternative embodiment of the bracket 82 together with the rail system 58 of the embodiment is shown from two different perspectives. Figures 17 and 18 The illustrated variant of the bracket 82 has two types of mounting holes 85, each of different sizes. Both types of mounting holes 85 are largely round. A component 17 can be suspended in the larger mounting holes 85. A component 17 can be screwed into the smaller mounting holes 85.

[0074] It is advantageous if the holder 82 has fastening openings and / or further receptacles which are adapted or adaptable to typical or customary fastening systems for components 17. The holder 82 has two tabs 86 on its front side, which can be placed on the front side of the two rails 78. The tabs 86 have a Figure 18The bracket 82 has the illustrated mounting hook 87, with which the bracket 82 can be hooked into the mounting holes 80. The bracket 82 has mounting holes 80 on the tabs 86, which fit into the mounting holes 80 of the rails 78. In this way, the bracket 82 can be attached to the rail system 58 using bolts, clip elements, clamps, and / or screws that can be inserted into the mounting holes 80.

[0075] In the exemplary embodiment, the rails 78 have fastening holes 80 with three different geometries. The fastening holes 80 are arranged in groups 88, each with three fastening holes 80 with different geometries. A group 88 has one elongated hole 80a, one rectangular hole 80b, and one round hole 80c (see Figure 13). In the exemplary embodiment, the elongated hole 80a is arranged above the rectangular hole 80b. The rectangular hole 80b is arranged above the round hole 80c. In the exemplary embodiment, the elongated hole 80a has a height of 5 cm. The elongated hole 80a has a width of 2.2 cm. The rectangular hole 80b has a height of 3.5 mm. The rectangular hole 80b has a width of 1.6 mm. The round hole 80c has a diameter of 4 mm. The groups 88 of fastening holes 80 have a hole spacing 94. In the exemplary embodiment, the hole spacing 94 is 20 cm. In the exemplary embodiment, the hole spacing 94 is half a standard component height. In the exemplary embodiment, the standard component height is a minimum height for components 17 that can be installed in the housing 15.

[0076] In alternative variants, the fastening holes 80 and / or groups 88 of fastening holes 80 largely have a hole spacing 94 from one another that is between one eighth and one half, preferably largely one quarter, of a component height of the at least one component 17 or of a standard component height. If the fastening holes 80 and / or groups 88 of fastening holes 80 largely have a hole spacing 94 from one another that is between one eighth and one half, preferably largely one quarter, of the component height of the at least one component 17 or of the standard component height, this is a particularly advantageous implementation of a modular system. The at least one component 17 can be installed in the housing in a particularly variably manner. A group 88 of fastening holes 80 is understood to mean a set of holes that have a specific, predetermined arrangement and / or geometry within the group 88.It is advantageous if the rail system 58 has a plurality of groups of fastening holes 80 which are largely similarly constructed or structured. For example, a group 88 of fastening holes 80 can each have a rectangular fastening hole 80 and a round fastening hole 80 arranged horizontally next to it. In this way, for example, different fastening methods can be used, for example for different components 17. This group 88 of two fastening holes 80 can now be arranged multiple times on a largely vertical rail system 58, each with a vertical distance of, for example, a quarter of the standard component height from the next group 88 of fastening holes 80. In this way, the at least one component 17, in particular at least two components 17, can be arranged in the housing 15 in a particularly space-saving manner and the volume of the housing 15 can be used particularly efficiently.

[0077] In the exemplary embodiment, it is provided that the holder 82 can be hooked into the elongated hole 80a via at least one holder hook 87. A sheet metal nut can be inserted through the rectangular hole 80b. If a sheet metal nut is inserted into the rectangular hole 80b, a screw can be screwed onto the sheet metal nut and passed through the round hole 80c. The holder 82 has at least one round hole 80d (see Figure 17 ), through which a screw can be passed. The round hole 80d of the bracket 82 lies above the round hole 80c of the rail system 58 when the bracket 82 is suspended in the elongated hole 80a. In the illustrated embodiment, the round hole 80d has a diameter of 8 mm. If a sheet metal nut is inserted into the rectangular hole 80b, the bracket 82 can be screwed to the rail system 58 with a screw.

[0078] It is conceivable that further components 17 have means for direct attachment to the rails 78. For example, it is conceivable that a component 17, such as a gas condensing boiler 40, has hooks or retaining hooks 87 for attachment to the attachment holes 80 of the rail system 58.

[0079] The housing 15 has a thermal insulation 96 (see Figure 11). In the exemplary embodiment, the thermal insulation 96 is composed of rigid foam insulation panels. The thermal insulation 96 largely has a thickness of 6 cm. In alternative embodiments, the thickness of the thermal insulation 96 can assume values ​​between 3 cm and 10 cm, preferably between 5 cm and 8 cm. The thermal insulation 96 is at least partially enclosed with metal plates 98. In the exemplary embodiment, the metal plates 98 are powder-coated steel sheets. The metal plates 98 largely have a thickness of 1.5 mm or largely 2 mm. In alternative embodiments, the metal plates 98 have a thickness between 0.5 mm and 3 mm, particularly preferably between 1 mm and 2 mm. Along the insulation layer depth 76, the thermal insulation 96 is enclosed on the inside and outside with metal plates 98.In the exemplary embodiment, the metal plate 98 on the inside has a thickness of approximately 2 mm, and the metal plate 98 on the outside has a thickness of approximately 1.5 mm. A door 100 has a thermal insulation 96, which has a metal plate 98 on its inside and outside. The metal plates 98 of the door 100 each have a thickness of approximately 1.5 mm. The thermal insulation 96 has a sandwich construction in the door 100 and along the second width 76.

[0080] In the exemplary embodiment, the housing 15 is designed to be enclosed in an outer cladding 74 of the building 12. A layer of insulating material (not shown) applied between the outer cladding 74 and the outer wall 48 for thermal insulation of the building 12 is interrupted at the location of the housing 15. The insulation 96 of the housing 15 is advantageous for ensuring the best possible thermal insulation of the building 12. The housing 15 is part of the insulation for thermal insulation of the building 12.

[0081] An upper portion 102 of the housing 15 is not thermally insulated. Figures 12 , 14 and 16the upper sub-area 102 is illustrated. Behind the upper sub-area 102 is a rear sub-area 104, which has thermal insulation 96. The rear sub-area 104 has the insulation layer depth 76. The rear sub-area 104 is located between the outer wall 48 and the outer cladding 74. The uninsulated upper sub-area 102 is located outside the outer cladding 74. The upper sub-area 102 is intended for components that do not require thermal insulation 96 and / or that benefit from extreme outside temperatures or at which extreme outside temperatures enable advantageous operation. In particular, the upper sub-area 102 is intended to house an outdoor unit 60 of an air-water heat pump 62 (see Figure 6) and / or an outdoor unit of an air conditioning system. Advantageously, the housing 15 has openings in the upper portion 102. This allows for a particularly high temperature exchange. Figure 6 In the embodiments shown, the housing 15 has large-area opening grilles 70 in the area of ​​the upper portion 102.

[0082] On the right housing side 27 and left housing side 28, outside the outer cladding 74 and below the upper portion 102, the thermal insulation 96 is covered by outer panels 106. The outer panels 106 are attached to retaining clips 108. The retaining clips 108 extend through the thermal insulation 96 and are connected to the internal metal plates 98. In the exemplary embodiment, the outer panels 106 are made of a high-pressure laminate (HPL). In the exemplary embodiment, the outer panels 106 have a thickness of 1 cm. In alternative embodiments, the outer panels 106 can have any desired thickness. It is also conceivable for the outer panels 106 to be made of different materials. It is intended that the outer panels 106 are easily replaceable. In this way, it is possible to individually adapt the appearance of the system 10.It is also conceivable that the housing 15 can be adapted to external conditions using the outer panels 106. For example, it is possible for the outer panels 106 to comprise additional thermal insulation material. In this way, the housing 15 can be adapted to regions with particularly cold climates or weather. Furthermore, it is conceivable for the outer panels 106 to have a special geometry. For example, the outer panels 106 can be wedge-shaped and / or have the shape of a quarter circle and / or be curved. In this way, it is possible, for example, to adapt the aerodynamics of the housing 15. Outer panels 106 with a special geometry can be less sensitive to wind influences than flat outer panels 106.

[0083] In further variants, it is conceivable that spacer elements are provided for attachment to the rear of the housing 29. In this way, it is possible to compensate for any unevenness of the outer wall 48 of the building 12. The rear of the housing 29 can thus be adapted to the outer wall 48. This is particularly advantageous for length or depth compensation. In older buildings 12, it is possible that the outer wall 48 has bulges or dents or depressions or indentations along its height. It is particularly possible that an outer wall 48 is not sufficiently flat. The spacer elements can be individually adapted to the building 12 or the outer wall 48. It is also conceivable that a kit of spacer elements, in particular with adjustable spacer elements, is provided, which enables adaptation to different outer walls 48.

[0084] Figure 19shows an exploded view of a variant of the housing 15. Figure 19 illustrates the arrangement of the thermal insulation 96 and the metal plates 98. The internal metal plates 98 of the right housing side 27, left housing side 28, a housing back 29, a housing top 31 and a housing bottom 33 (see also Figures 3 and 4 ) form a housing 107 which has two openings for the doors 100 only on the front side 26 of the housing.

[0085] In the exemplary embodiment, the housing 15 has internal lines 44. The internal lines 44 connect the components 17 to the lines 13. The housing 15 has connections (not shown) to which the lines 13 can be connected. The lines 13 can be connected to the lines 44 via the connections. In the exemplary embodiment, the connections are located on the rear side 29 of the housing. The position of the connections is adapted to the position of the lines 13 in the building 12. It is conceivable that the housing 15 has connections for further lines 13 for an energy supply system and / or ventilation system, for example for a piping system for a heat transfer fluid of a solar thermal system.

[0086] In alternative embodiments, the housing 15 has one or more openings through which one or more lines 13 of the building 12 can be passed. In these embodiments, the lines 13 run within the housing 15 and at least partially replace the internal lines 44. It is conceivable that the housing 15 has openings for additional lines for an energy supply system and / or ventilation system, for example, for a line system for a heat transfer fluid of a solar thermal system.

[0087] It is also conceivable for the housing 15 to have openings for direct air supply and / or direct air removal, in particular without the use of an air duct system. For example, the building 12 can have a ventilation opening on its outer wall 48. The housing 15 has an opening on its rear side 29 that matches the ventilation opening, through which used exhaust air 16 is directly extracted through the ventilation opening or through which fresh air 69 is directly introduced into the building 12. The position of the at least one opening in the housing 15 is adapted to the position of the ventilation lines 22, service water lines 18, heating water lines 20, and the gas line 42.

[0088] In particular embodiments, it is conceivable for the housing 15 to be completely or largely completely open at its rear side 29. In these embodiments, the housing 15, in particular, has no metal plate 98 on the rear side. In this way, lines 13 of the building 12 can be guided into the housing 15 particularly easily and flexibly. In these embodiments, the housing 15 is preferably provided to be attachable to the outer wall 48 of the building, so that the outer wall 48 largely closes the open rear side of the housing. Particularly preferably, the housing 15 can be attached to the outer wall 15 in a sealed manner.

[0089] In the exemplary embodiment, the housing 15 has two shafts 110 (see Figures 11 to 13). The shafts 110 run vertically along the housing height 56. A shaft 110 consists of a sheet metal folded once and has, on average, largely an L-shaped profile. In the exemplary embodiment, both shafts 110 are located in the rear region of the housing 15, in particular also in the rear partial region 104. The two shafts 110 are each connected to the housing rear side 29 and the right housing side 27 or the left housing side 28. In the exemplary embodiment, the shafts 110 are welded to the internal metal plates 98. In alternative embodiments, the shafts 110 or a shaft 110 is connected to the housing 15 by gluing and / or screwing and / or riveting and / or soldering and / or joining, in particular clinching.

[0090] In alternative embodiments, at least one shaft 110 comprises a metal sheet and is attached to at least one housing wall of the housing 15, in particular to a housing rear side 29. If the at least one shaft 110 comprises a metal sheet and is attached to a housing wall of the housing 15, in particular to a rear housing rear side 29, the housing 15 is stiffened and thus mechanically stabilized.

[0091] In the exemplary embodiment, the two shafts 110 are provided to mechanically stabilize the housing 15. In alternative embodiments, one or more shafts 110 can carry at least one line 13 and / or internal lines 44, in particular an air line and / or power line and / or water line and / or fuel line. It is conceivable that one shaft 110 serves as an air line.

[0092] If the shaft 110 has at least one line 13 or carries at least one line 13 and / or serves as an air line, the volume of the housing 12 is utilized particularly efficiently. Furthermore, the lines 13 are protected from damage. This is particularly advantageous when repairs and / or maintenance work is being performed on the at least one component 17.

[0093] In the exemplary embodiment, the shafts 110 have a shaft width 112 of 5 cm. Any other shaft widths 112 are conceivable in alternative embodiments. The value of the shaft width 112 depends on the technical requirements, in particular the desired stability of the housing 15 and / or the size or volume of devices or objects to be accommodated in the shaft 110, for example, pipes and / or lines 13.

[0094] In the exemplary embodiment, the shafts 110 have a shaft depth 114 of largely 22 cm. The shafts 110 are delimited along the shaft depth 114 by the metal plate 98 of the housing rear 29 and the internal metal plate 98 of the thermal insulation 96, which separates the rear partial region 104 from the upper partial region 102. In the exemplary embodiment, the shaft depth 114 is largely constant along the housing height 56. In alternative embodiments, the shaft depth 114 can assume any desired other values; in particular, the shaft depth 114 can vary along the housing height 56. For example, the shaft depth below the upper partial region 102 can be greater than at the level of the upper partial region 102. The value of the shaft depth 114 depends on the technical requirements, in particular on the desired stability of the housing 15 and / or on the size or volume of devices orObjects that are to be accommodated in shaft 110, for example pipes and / or cables.

[0095] In the exemplary embodiment, the shaft depth 114 is approximately 0.275 times the housing depth 52. The ratio of the shaft depth 114 to the housing depth 52 is between one-fifth and one-third. In the exemplary embodiment, the shaft 110 has a particularly stabilizing effect on the housing 15.

[0096] In the Figure 12In the illustrated embodiment, the housing 15 has a holding device 116. The holding device 116 is intended to fasten lines 13, in particular power lines 36 and internal lines 44. In the embodiment shown, the holding device 116 has five clamps 118. The clamps 118 each have a largely round inner profile with an opening or perforation. The clamps 118 are intended to accommodate lines 13, in particular pipes and / or cables with a largely round cross-section. A respective radius of the inner profiles of the clamps 118 is adapted to the radii of the lines 13, in particular the internal lines 44 and power lines 36. In the exemplary embodiment, the clamps 118 have four different radii of the inner profiles.

[0097] The clamps 118 are partially made of an elastic plastic. The lines, in particular pipes and / or cables, can be clipped or plugged into the clamps 118. The holding device 116 of the embodiment shown has the advantage that lines 13 can be attached and detached easily and quickly. The use of tools is not necessary. In alternative embodiments, other fastening mechanisms are used to implement the holding device 116. For example, it is conceivable that lines 13 can be snapped into the holding device 116. It is also conceivable that the holding device 116 has clamps or hose ties. The clamps or hose ties can have a largely annular band, in particular made of metal or plastic, at least one wire, or a fabric. The clamps orHose ties can have a closure element, for example a worm thread, a tensioning screw or a tensioning belt closure, in particular with a ratchet.

[0098] The holding devices 116 of the embodiment shown are arranged at substantially uniform intervals along the housing height 56 ​​of the housing 15 (see Figures 14 and 15 ). In the embodiment shown, the holding devices 116 are attached to the housing rear 29 as well as to the right housing side 27 and the left housing side 28. In further embodiments, the positioning of the holding device 116 depends on the technical requirements, in particular on the desired routing of air lines and / or power lines and / or water lines and / or fuel lines. For example, it is conceivable for a shaft 110 to have a holding device 116.

[0099] In the Figure 6In the embodiment shown, the housing 15 has safety valves 120. The safety valves 120 are shown in the detailed illustration in Figure 16shown. All water lines leading to the indoor unit 64 can be closed off with the safety valves 120. In this way, the indoor unit 64 can be completely separated from the water lines 18, 29, 44 in the housing 15. This has the advantage that the indoor unit 64 can be separated from the system 10 particularly easily. This enables quick and convenient maintenance and / or replacement of the indoor unit 64. In further variants, other components of the system 10 can be separated from the system 10 by valves or safety valves 120. In particular, it is advantageous if lines 13, in particular water lines and / or lines for heat transfer medium and / or fuel lines, can be separated by valves or safety valves 120. It is also conceivable for the housing 15 to have a valve assembly which, with the aid of a switch or switching element, in particular a lever, and / or a control command, largely separates the system 10 from the building 12 orthrough which virtually all lines 13 leading into the building 12 can be interrupted. The valve assembly enables a particularly rapid emergency shutdown or emergency disconnection of the system 10. In the embodiment shown, the internal lines 44 have the safety valves 120. In variants in which lines 13, in particular water lines and / or heat transfer lines and / or fuel lines, are led into the housing 15, in particular from the building 12, the lines have one or more valves or safety valves 120.

[0100] In the Figure 7In the embodiment shown, the housing 15 has an outside temperature sensor 122. The outside temperature sensor 122 is mounted in the upper portion 102. The upper portion 102 is not thermally insulated and has a large-area opening grille 70. In this way, the outside temperature sensor 122 can reliably determine an outside temperature. The outside temperature determined using the outside temperature sensor 122 can be used to control the heating system of the building 12. In the embodiment shown, the outside temperature sensor 122 is connected to a room control unit 126 via a communication link 124. The room control unit 126 is mounted within the building 12. The room control unit 126 detects an interior temperature. The room control unit 126 has means for receiving user inputs. In particular, a user can set a desired interior temperature.In the embodiment shown, the room control unit 126 is connected to the outdoor unit 60 and the indoor unit 64 of the air-water heat pump 62 via the communication link 124. The room control unit 126 is provided for controlling or regulating the heating system.

[0101] In further variants, the housing 15 has at least one sensor, in particular for use with the energy supply system and / or ventilation system of the building 12, for example a temperature sensor, in particular a temperature sensor for monitoring an insulated interior region of the housing 15, and / or a vibration sensor and / or a microphone and / or a water sensor. A vibration sensor or a microphone can be used, for example, to detect defects or malfunctions and / or suboptimal operation of components. A vibration sensor or microphone is also suitable for monitoring noise development or noise pollution caused by the system 10. With the help of the water sensor, it can be determined whether water has penetrated the housing 15. Water can penetrate into the housing 15, for example, through damage to the housing 15 or incorrectly closed openings.Water in the housing 15 may also indicate damaged water pipes or damaged internal pipes 44.

[0102] It is conceivable that, in special variants, the housing 15 may include a smoke detector. The smoke detector may be designed to detect smoke development within the housing. This enables safe and trouble-free operation, and potential defects and / or malfunctions in the system 10 can be detected early. The smoke detector may be designed to detect smoke development or a fire in the building 12. This has the advantage of increasing safety in the building 12, particularly the safety of the residents of the building 12.

[0103] It is conceivable that the system 10 is connected to at least one further sensor outside the housing 15 via a communication connection 124. For example, the system 10 can be connected to an air quality sensor, in particular a CO2 sensor inside the building 12, a temperature sensor in the building 12, or a temperature sensor of a solar cell of the photovoltaic system. In this way, the components of the system 10 can be operated more safely and efficiently.

[0104] In the Figures 1 to 3In the exemplary embodiment shown, the housing 15 has a chimney 128. The chimney 128 is provided for directing exhaust gases from the gas condensing boiler 40 to the outside. In the exemplary embodiment, the chimney 128 leads into the upper partial area 102. The upper partial area 102 has the opening grille 70. The exhaust gases from the gas condensing boiler 40 can escape to the outside via the opening grille 70. In variants of the exemplary embodiment, it is conceivable for the chimney 128 to be attached to an outer shell of the housing 15, in particular to the upper side 31 of the housing. In this way, exhaust gases can be directed directly to the outside. The chimney 128 is an opening in the housing 15 for exhaust gases.

[0105] In the exemplary embodiment, the housing 15 has an exhaust air opening 130. The exhaust air opening 130 is an opening in the housing 15 for exhaust air. The exhaust air opening 130 is provided for directing exhaust air cooled by the ventilation heat pump 14 to the outside. In the exemplary embodiment, the exhaust air opening 130 is a rectangular recess in the outer panel 106. The exhaust air opening 130 is arranged on the right-hand side 27 of the housing. The rectangular recess in the outer panel 106 has horizontal slats. The slats are inclined downwards or are arranged such that a surface of the slats is at an angle of approximately 45° to a surface of the outer panel 106. This makes it more difficult for rain to penetrate the exhaust air opening 130. The ventilation heat pump 14 is connected to the exhaust air opening 130 via an exhaust air duct 132. The exhaust air duct 132 is flush with the outer panel 106.The thermal insulation 96 has a recess in the area of ​​the exhaust air opening 130, allowing the exhaust air duct 132 to pass through. In the exemplary embodiment, the exhaust air duct 132 has thermal insulation.

[0106] The housing 15 of the Figure 7The embodiment shown has a fresh air opening 134. The fresh air opening 134 is an opening in the housing 15 for fresh air. The fresh air opening 134 is intended to direct fresh air to the ventilation unit 66. In the embodiment shown, the fresh air opening 134 is a rectangular recess in the outer panel 106. The fresh air opening 134 is arranged on the right-hand side 27 of the housing. The rectangular recess in the outer panel 106 has horizontal slats. The slats are inclined downwards or are arranged such that a surface of the slats is at an angle of substantially 45° to the surface of the outer panel 106. In this way, the penetration of rain into the fresh air opening 134 is made more difficult. The ventilation unit 66 is connected to the fresh air opening 134 via a fresh air duct 36. The fresh air duct 136 is flush with the outer panel 106.The thermal insulation 96 has a recess in the area of ​​the fresh air opening 134, allowing the fresh air duct 136 to pass through. In the embodiment shown, the fresh air duct 136 has thermal insulation. The exhaust air cooled by the ventilation unit 66 is guided via an exhaust air duct 132 to an exhaust air opening 130 in the housing 15. In the embodiment shown, the exhaust air opening 130 is located in the upper section 102.

[0107] In particular variants of the system 10, the housing 15 has an outlet 138, in particular for rainwater and / or wastewater from the building 12 and / or for condensate. For example, it is conceivable that a downpipe for rainwater present on the building 12 can be accommodated by the housing 15. The housing 15 can have openings and / or holding devices 116 provided for this purpose. In particular embodiments, the shaft 110 forms a downpipe for rainwater and / or wastewater.

[0108] In the exemplary embodiment, the housing 15 has a drain 138. The drain 138 is located on the housing underside 33. The drain 138 directs, in particular, the condensate into a drainage system of the building 12. In variants, it is conceivable for components 17 of the system 10 to be connected to the drain 138 via lines 13, in particular internal lines 44. In particular, the outdoor unit 60 of a heat pump and / or an air conditioning system and / or a condensing boiler can be connected to the drain 138 via lines 13. In this way, condensate forming there can be directed out of the housing 15 particularly safely and efficiently.

[0109] In the exemplary embodiment, a base 140 inside the housing 15 is curved in a funnel shape, so that a height of the base 140 decreases towards an opening (see Figure 3). The opening of the base 140 is connected to the drain 138. In this way, liquids flow from the base 140 via the drain 138. In this way, in particular, water that has undesirably penetrated into the housing 15 can be automatically drained away. It is also conceivable for the housing 15 to have additional funnel-shaped water collection elements, in particular below components 17, which are connected to the drain 138 via lines 13. The funnel-shaped water collection elements can be designed as intermediate floors in the housing 15.

[0110] In the exemplary embodiment, the housing has two doors 100. The doors are an example of covering devices 141 for openings in the housing 15. The doors 100 have the thermal insulation 96 (see Figure 11). The thermal insulation 96 is sandwiched between two metal plates 98. The doors 100 close the housing 15 almost completely. In the exemplary embodiment, the doors 100 are arranged one above the other along the housing height 56. The doors 100 have a seal 142. In the exemplary embodiment, the seal 142 has a dart profile (see Figure 20 ). In the exemplary embodiment, the housing 15 has an additional seal 142 for sealing the door or doors (see Figure 16 ). In special variants, the seal 142 of the housing 15 has a D-profile (see Figure 21 ). The seals 142 are preferably made of rubber and / or a deformable plastic, in particular PVC. In the exemplary embodiment, magnets are attached to the door 100 in the area of ​​the seal 142. The door 100 can be pressed or pressed against the ferromagnetic housing 15 with a magnetic force. In this way, the housing 15 is particularly well sealed.

[0111] In the exemplary embodiment, the doors 100 each have a damper 144. The damper 144 is connected to the housing 15. In this way, the speed at which the door 100 is opened can be controlled. The damper 144 also controls the force with which a door 100 is opened or closed. In this way, an unintentional closing of the door 100 or an unintentional opening of the door 100, for example due to wind, can be prevented. In the exemplary embodiment, the damper 144 is a pneumatic damper. The door 100 can be fixed at an opening angle of approximately 120° in the exemplary embodiment. This facilitates maintenance work on the components in the housing 15 (see Figure 22 ).

[0112] In the exemplary embodiment, the doors 100 have hooks 146 on their inner sides. The hooks 146 are provided for hanging covers and / or other parts of components 17 that are removed during inspection and / or maintenance. The hooks 146 are also suitable for hanging tools. This further simplifies inspections and / or maintenance. It is conceivable that the doors 100 have other fastening devices, for example, magnetic holders, clamps, or elements for latching or clipping.

[0113] In the exemplary embodiment, the upper door 100 is partially insulated and is firmly connected to a cover of the housing top 31, the housing front 26 and the right housing side 27 in the upper section 102. If the upper door 100 is opened, the cover of the housing top 31, the housing front 26 and the right housing side 27 in the upper section also opens (see Figures 1 , 2and 19 ). Figure 22 shows a variant in which the upper portion 102 remains closed when the upper door 100 is opened. It is conceivable that the upper portion 102 has its own door 100, which, for example, largely closes the housing front 27 in the upper portion 102.

[0114] In the exemplary embodiment, the housing 15 has two doors 100. One door 100 is a cover device 141. In other embodiments, any number of doors 100 or cover devices 141 is conceivable. The number of cover devices 141 is determined in particular by the building height 56. The number, shape, and arrangement of the cover devices 141 are advantageously determined by the arrangement of components 17 in the housing 15, in particular so that easy access to the components 17 is ensured, especially for components 17 that require regular inspection or maintenance.

[0115] In preferred embodiments, at least two cover devices 141 are arranged one above the other along a housing height 56 ​​of the housing 15. Arranging at least two cover devices 141 one above the other along the housing height 56 ​​of the housing 15 has the advantage that the at least one component 17 of the housing is particularly easy to reach. This simplifies inspections and maintenance work.

[0116] In alternative embodiments, the covering device 141 can be designed in any desired manner. For example, the covering device 141 can be a cover that can be completely separated from the housing 15 and / or a rolling grille and / or a sliding door and / or an at least partially deformable top, in particular elastically deformable, in particular made of a fabric.

[0117] In the exemplary embodiment, the doors 100 have a door lock 148. The door lock

[0118] 148 is an example of a locking device 150. In the exemplary embodiment, the door lock 148 can be locked with a key. In this way, only authorized persons have access to the components 17 of the system 10. In variants, alternative locking devices 150 are conceivable, in particular electronic locking devices 150, particularly preferably contactless electronic locking devices 150, for example via a chip card or an NFC system. If the cover device 141 can be locked with a locking device 150, in particular by a door lock 148, access by unauthorized persons is excluded. Intentional or accidental disruptions to the system as well as vandalism are thus largely restricted. In this way, safe and trouble-free operation of the system 10 is ensured.

[0119] In further embodiments, it is conceivable for the housing 15 to have a compartment system. The compartment system is intended for storing objects in the housing 15. It is advantageous if the compartment system is lockable, in particular with a different locking device 150 than the covering devices 141 that grant access to the other components 17 of the system 10. It is conceivable for the compartment system to have its own covering device 141. In this way, it is possible, for example, for a postal service provider to deposit a parcel in the compartment system of the housing 15, to which only authorized persons have access. It is also conceivable for the compartment system to have means for cooling, for example a refrigerator and / or an icebox. In this way, it is possible to store perishable foodstuffs in the compartment system, at least temporarily.

[0120] In further variants of the system 10, the housing 15 has an internal heating system. The internal heating system is provided to heat at least one component 17 in the housing 15, if necessary, to the required minimum temperature. This is advantageous when the housing 15 has to be opened for extended periods at low outside temperatures, for example, for maintenance. The heating system can be an electric heating system. It is conceivable that the heating system is arranged in a shaft 110.

[0121] In further embodiments, intermediate floors are provided in the housing, which divide the housing 15 largely horizontally. In particular, the intermediate floors are intended to prevent air or gas exchange between different heights along the housing height 56. In this way, a chimney effect is prevented. The chimney effect can intensify or accelerate fires. It is conceivable that the intermediate floors are at least partially funnel-shaped so that they can collect water that has penetrated into the housing 15. The at least partially funnel-shaped intermediate floors are advantageously connected to the drain 138 by lines 13.

[0122] Examples of further components 17 of the energy supply system and / or ventilation system for a building 12 are a heating device, in particular a condensing boiler, a heat pump, a ventilation device, a ventilation unit, a heat transfer tank, in particular for a solar thermal system, a heat exchanger, in particular for district heating, or a pump.
