Description

Heating module for integration into a shell of a house

The invention relates to a heating module for integration into a shell of a house, as described in the preamble of claim 1.

From AT 008 552 Ul a device for a biomass heating device, a buffer memory, a solar collector, a cooling device and a fuel storage is known. The device is used for the optimal automatic supply of a building with heating, for cooling and / or for heating domestic water. Due to its design, the device is a mobile heating and air conditioning for building close assembly. For this purpose, a stable floor element is assembled via at least three supporting wall elements with a ceiling element to a power supply chamber. A wall forms a solar collector village. This results in an isolated space for the inclusion of fuels from biomass, for heating or cooling devices, a buffer memory and the control and regulating devices. In addition, power generators may be provided for the power supply. Between fuel storage and equipment room a partition or a false ceiling is provided. A transport device provides for the controlled supply of fuel to the heater.

The disadvantage here is that the large space requirement and close to the building makes it impossible to use the transmission losses. Another disadvantage is the weather-exposed installation, which can cause damage by storm, frost and / or power failures. Furthermore, heat losses occur through long connecting lines between the device and the heat dissipation system (house).

Furthermore, from DE 196 02 869 A an assembly that forms a surrounding core of walls for a building, preferably for a residential building, known. For this purpose, supply devices, in particular heating devices, are arranged in the core, wherein the walls are designed for the release of heat into spaces which adjoin the core.

The disadvantage here is that here no compact and self-tuned heating system is provided, but heating devices are arranged only in the walls, the heating system is installed to supply the heating in a separate boiler room. The core is also used for installations, staircases, etc., but not as a boiler room with fuel storage. From DE 202 19 041 Ul a heater for heating a building can be seen, which is designed for burning solid biomass fuels, and is installed in a heater housing. The heater housing is buried in the ground outside the building to be heated.

The disadvantage here is that it is not integrated into a residential building and thus transmission losses occur.

A heater for heating a building is also known from DE 102004 007 705 B4, wherein the heater is designed for burning solid biomass fuels and is installed in a heating housing arranged outside the building to be heated, in which a fuel storage reservoir is integrated and which is in a roof wall has a closable roof opening. The heating housing has a closable entry opening in a side wall, wherein it can be arranged such that, after opening the entry opening and the roof opening, it can be driven by a transport vehicle and the fuel storage store can be filled by tilting the transport vehicle.

The disadvantage here is that due to the nature of the fuel feed vehicles must drive directly to the fuel storage to this infestation, so installation in a house is not possible.

The invention has for its object to provide a heating module, with a compact and faster construction and a self-matched unit for supplying a house is achieved. Another object of the invention is to ensure the well-being of the homeowner and a pleasant living comfort.

The objects of the invention are achieved in that a viewing window is arranged on a side wall of the energy box and that the window disposed in the energy box heating system is assigned such that during operation of the heating system through the viewing window, a fireplace is visible.

In this case, it is advantageous that a portion of the heat energy flows via the viewing window to the living space adjacent to the viewing window; is discharged and thus a faster heating is achieved. At the same time, the heating capacity of the central heating system can be reduced in this living room. Another advantage is that for the user the fireplace is visible, but no noise is perceptible, since all components in the power box, which is designed to sound, water and smoke-tight, arranged, unlike in the prior art known stoves with windows that are placed in the living room, and where the user must accept noise (fan, screw conveyor, etc.). Such a power box combines the advantages of a free-standing in the living room stove through the window with regard to well-being and direct heat dissipation with those of a closed boiler room, which ensures the fire safety and energy supply for the entire house over a longer period. A significant advantage is that the energy box is integrated into the house, so that the heat generated in the energy box, which is also partially discharged through the walls, not lost, but is better used, thus increasing the overall efficiency of the heating module, this also in terms of energy supply and protection of the environment. Another advantage is that the high degree of prefabrication of the heating system avoids errors at the construction site. It is also advantageous that all inspection work, such as ash discharge, not on the window (living room), but are performed by the interior of the power box. This will not cause pollution of the adjacent living space.

An advantage is an embodiment in which the viewing window is attached to or in the side wall and the heating system is positioned on the opposite side airtight to the side wall or connected to the side wall, as a result of very different possible variations in the design of the viewing window and thus a Adaptation to the subsequent housing device both visually and in the strength and size of the viewing window, and thus the heat through the viewing window, is possible.

But it is also an embodiment of advantage in which the viewing window is connected to the heating system via a connecting web to a unit and the connecting web, a flange is arranged, with which the side wall is connected, as a self-contained commercial furnace with window in the energy box can be installed.

Also advantageous is an embodiment in which a liquid-carrying hot water tank is arranged in the energy box, which is connected to the heating system for heating the arranged in the hot water tank liquid, as is achieved by the fact that a hot water supply to the house is possible through the power box.

Another advantage is also an embodiment in which a fuel storage for the heating system is arranged in the energy box, as a compact, space-saving design, without further storage space is achieved.

But it is also an embodiment of advantage in which the fuel storage is separated by a partition wall of the heating system and the other components and for filling has a connection piece, as a spatial separation between fuel and the individual components is achieved in case of fire or water leakage ,

In an embodiment in which the fuel storage is dimensioned such that the heating system is usually supplied with fuel for a year, is achieved in an advantageous manner that only once a year, a filling is required without dirt and dust pollution for the surrounding living spaces ,

However, it is also an embodiment of advantage, in which further components such as a power storage and / or a self-sufficient power supply with PV system and inverter, etc. are arranged in the power box, as characterized in case of power failure, the individual components over a certain period of time can be operated as well as an emergency power supply for the whole building is given.

Another advantage is also an embodiment in which the energy box is equipped as a watertight trough and preferably a floor drain for connection to the house channel is equipped, as it can not escape into the adjoining living spaces in a water damage in the energy box, the liquid.

Advantageously, an embodiment in which the power box is airtight and has corresponding supply and exhaust ports, as this no toxic gases can escape into the living room and in the event of fire due to the built-in security measures the fire can be reduced as quickly as possible.

But it is also advantageous that the heating system is formed by a pellet heating and / or firewood heating in order to achieve a cost-effective and environmentally friendly and crisis-proof fuel supply.

But is also an embodiment in which the heating system is in addition to the central heating still equipped with an air heater for rapid heating of certain rooms, including corresponding outlets are arranged in the side walls and in the power box one or more fans are arranged over Pipes conveyed by the heating system or the hot water storage air through the outlets in the adjacent room, as a targeted and rapid heating of various living spaces is achieved.

Advantageous is an embodiment in which a hot water heater is installed in the power box, which allows a self-sufficient healthy cooking / cooking and heating of the hot water this is connected to the hot water tank, as this cost-effective cooking and cooking on the heating system is possible.

But it is also an embodiment in which the air heating is connected to a controlled living space ventilation, advantage, since the heating of the house on the living room ventilation is made possible without additional installations.

An advantage is an embodiment in which the interior is equipped with a draft regulator, which dissipates the warm air in the interior of the energy box in the summer and the cool incoming air can flow on the supply air, is equipped, as this overheating of the power box is prevented. Finally, a configuration of advantage in which the air heating, preferably in the summer, for gently dehydrating vegetables, fruits and herbs is connected to a box, as this the air heating, which operated over the hot water tank, the cost and environmentally friendly on the solar system can be used to dehydrate.

7 shows a further detailed view of the energy box, in particular the integration of a heating system in the energy box, in a simplified, schematic representation;

Fig. 8 is a perspective view of the use of the energy box in a house, in a simplified, schematic representation. In FIGS. 1 to 8, a heating module, in particular an energy box 1, is shown, which is closed all around and is accessible via a door 2. That is, the power box 1 has a bottom plate 3, four side walls 4 and a ceiling 5, wherein on a side wall 4, the door 2 is arranged, via which one can get into the interior 6 of the power box 1. The heating module or the energy box 1 is used for heat supply of houses 7, preferably of single-family homes, with visible fire in the living space 8. For this, the energy box 1 can be placed by means of a crane in the shell on the foundation plate or the bare ceiling of the house 7. For example, the energy box 1 for the supply of a low energy house dimensions with a width of 160 cm, length of 220 cm and a height of 275 cm.

The bottom plate 3 is preferably equipped as a watertight trough 9 and has a bottom drain 10 for connection to the house channel, which ensures that leaking liquids from the interior 6 of the energy box 1 can not escape to the outside.

Inside the power box 1 now different components are included. In particular, a functional heating system 11 together with associated lines and power supply is arranged therein. Here, a viewing window 12 is disposed on a side wall 4 of the power box 1 and arranged the viewing window 12 in the power box 1 heating system 11 such that during operation of the heating system 11 through the viewing window 12, a fireplace 8 is visible, i. that through the viewing window 12 of the heating system 11, the fireplace 8 in the combustion chamber 13 of the heating system 11 is visible.

In this case it is possible, as can now better be seen from FIG. 6, to integrate the viewing window 12 directly on the outer surface or in the wall, wherein the viewing window 12 is designed such that it can be opened from the outside, ie outside the energy box 1 , This has the advantage that, with appropriate sooting of the viewing window 12, the user can clean it by opening the viewing window 12. At the same time it is achieved that by opening the viewing window 12, the heating system 11 can be filled with logs. The heating system 11, in particular the combustion chamber 13, is assigned to the side wall 4 in such a way that it rests airtight against the side wall 4, so that a closed combustion chamber 13 is formed. This is necessary insofar as it prevents toxic fumes from escaping from the combustion chamber 13 into the interior 6 of the energy box 1 or a living space of the house 7. Such an airtight design also has the advantage that in new low-energy houses and passive houses that have a living space ventilation, the operation of living space ventilation and the simultaneous operation of solid fuel heating in the living room is only allowed if a 100% Verbremiungsluftzuführung and tightness of the fireplace 8 to the living room given is.

Furthermore, however, an embodiment is possible such that in the side wall 4 of the power box 1, a known from the prior art heating system 11 is integrated with viewing window 12. For example, a heating system 11 of the "Evo Aqua" type from the company "SHT" can be installed. In this case, the viewing window 12 is connected via a connecting web 14 with the combustion chamber 13 of the heating system to be installed 11 and thus forms an airtight combustion unit closed, that is, from the front, so the viewing window 12 no air can flow into the combustion chamber 13.

By such a structure of the heating system 11, it is now possible to integrate by appropriate extensions, the heating system 11 in the side wall 4, including, as shown in Fig. 7, to the connecting web 14, a flange 15 is welded to the then the side wall. 4 is fixed or this flange 15 is walled or incorporated into the side wall 4. This achieves an airtight design in the region of the viewing window 12.

The air supply and -Rauchgasabfuhr via a special intake / exhaust pipe 16 which is arranged in the interior of the energy box 1, as better seen in Fig. 4 can be seen The intake / exhaust pipe 16 consists of an inner tube 17, which the exhaust air from the combustion chamber 13 leads, and an outer tube 18, sucked through the air and the heating system 11, in particular the combustion chamber 13, is supplied. In this case, the flue gas-carrying inner tube 17 is connected directly to a pipe of a chimney 19, so that the flue gas is safely guided through the chimney 19 to the outside. The outer tube 18 terminates on the side wall 4 of the power box 1 and the chimney 19, wherein within the power box 1 openings 20 are arranged on the outer tube 18 for sucking the air for the combustion chamber 13. Preferably, the openings 20 are arranged at the greatest possible distance from the heating system 11, as long as possible for a distance the heating of the supply air and at the same time cooling the exhaust air, so the exhaust gases to reach. In this case, it is possible for the openings 20 to be associated with closure flaps, so that regulation of the amount of the supplied supply air into the combustion space 13 can take place via a controller 21. In the illustrated embodiment, the supply air for the combustion of the heating system 11 is obtained from the interior 6 of the power box 1. Since the power box 1 airtight, in particular smoke-tight and in F90, so fireproof for 90 minutes, is executed and thus can not pass through the door 2 and the window 12 air into the interior 6 of the power box 1, the interior 6 via a corresponding supply air pipe 22 supplied from the outside with fresh air, which preferably takes place via a further pipe or via a further shaft of the chimney 19. This supply air pipe 22 may in turn be provided with a closure flap, so that the supply of fresh air is prevented via the closure flap in case of fire. Of course, it is also possible to connect the openings 20 of the outer tube 18 directly with the Zuluftrohr 22 and another tube of the chimney 19. The formation of the air supply by means of intake / exhaust pipe 16 is achieved in an advantageous manner that heated by the warm exhaust air, the colder supply air and thereby better combustion and better efficiency of the heating system 11 is achieved and at the same time heating the interior of the energy box 1 via 1 the warm exhaust air is prevented or reduced by the heat exchange with the supply air. Furthermore, it is also possible to suck in the supply air via suitable chimneys 19 via an annular gap, ie a double tube, and thus also to use the waste heat in the chimney 19 for preheating the supply air.

Furthermore, a fuel bearing 23 for the heating system 11 is arranged in the energy box 1. The fuel bearing 23 is separated by a partition wall 24 of the heating system 11 and the other components and has a connection piece 25 for filling. Here, the fuel bearing 23 is dimensioned such that the heating system 11 can usually be supplied with fuel for one year. In the above-mentioned dimensioning of the energy box 1 (width 160 cm, length 220 cm, height 275 cm), a storage volume of 3 m ^{3 is} integrated. This is achieved in such a way that the dividing wall 24, as can be seen in more detail in FIG. 5, extends obliquely over the entire surface of the energy box 1 in the upper area and when reaching a certain height extends perpendicularly to the base plate 3, so that between the side wall 4 and partition wall 24 in the region of the bottom plate 3 also a storage space is formed. Such a design of the fuel bearing 23 is preferably used for a pellet heating system, including the fuel bearing 23 via a screw conveyor 26 is connected to the heating system 11. The fuel bearing 23 can be filled with pellets via a ground line or by means of a hose from the building interior. Since the fuel bearing 23 is designed to be airtight, a possible smoldering fire in the fuel bearing 23 extinguishes by itself due to lack of oxygen.

The minimum design of the energy box 1 thus has a heating system 11 with associated fuel bearing 23, wherein preferably still listed below components for the energy supply of a house 7 in the interior 6 of the power box 1 are arranged.

These are shown in FIG. 8. The heating system 11 serves as a central heating for the house 7, that is, in the interior of the heating system 11 via the combustion chamber 13, a heat transfer medium, in particular liquid, is heated. Thus, in the power box 1 corresponding heat spreader 43 for connection to pipes to the radiators 27 and underfloor heaters 28 or wall heaters 29, etc. are arranged. For this purpose, a liquid-carrying hot water tank 30 is arranged in the energy box 1, which is connected to the heating system 11 for heating the arranged in the hot water tank 30 liquid. The individual heating circuits are also connected to the hot water tank 30, which is coupled to a surge tank 31, wherein the heating circuits are controlled via a central control unit 21 via corresponding valves and pumps. It is also possible that corresponding heat spreaders 43 are arranged. In addition, the power box 1 connections, in particular to the hot water tank 30, for connection to other heat energy sources, in particular a solar system 32, on. Thus, a parallel heating of the liquid in the hot water tank 30 of the heating system 11 and the solar system 32 can be achieved, the control of the energy supply due to the external weather conditions can be taken over by the central control unit 21. Furthermore, the hot water tank 30 is connected to a hygienic fresh water treatment 33, which in turn is connected to the lines for the service water, such as shower 34, sink, etc. Of course, it is possible that the hot water tank 30 is divided and has a range for the hot water, so that such a hygienic fresh water treatment 33 can be omitted. In addition, the hot water tank 30 may be equipped with a Heißwassergarbox 41 for gentle solar cooking / heating food. Furthermore, in the power box 1, for example, a power storage 35 and / or a self-sufficient power supply, etc. may be arranged, which is connected to a photovoltaic system 36, so that the components in the power box 1 can be powered even in case of power failure over a period of time with energy, that is, by the power storage 35, a self-sufficient operation of ignition, combustion fan, controller 21, circulating pumps, hot water and emergency lighting the power box 1 or a living room for several days is possible.

In order to achieve a rapid heating at least one subsequent to the power box 1 living room, the heating system 11 in addition to the central heating still an air heater 37, including corresponding outlets 38 are integrated in the side walls 4. Furthermore, one or more fans are arranged in the energy box 1, which convey the heated air from the heating system 11 via the outlets 38 in the adjacent room via pipelines, ie, that sucked in the illustrated embodiment according to FIG. 8 via an outlet 38, the room air is heated via the pipes or a heat exchanger 39 in the hot water tank 30 and discharged through the other outlet 38 into the living room. In this case, therefore, the sucked air is heated by the medium in the hot water tank 30, but it is also possible, the heat exchanger 39 spirally around the hot water tank 30, i. on its surface, to lead.

In addition, it is possible that the heating system 11 in addition to the central heating has an air heater 37, so heated directly over the combustion chamber 13, the sucked air from the living room and can be returned to the living room. With such a design of the heating system 11, the controller 21 can perform a control between central heating and air heating 37, ie that the user activates, for example on a control panel 40, a switching element, so that the controller recognizes that now a living room to be heated faster via the air heater. Then, the central heating is lowered by the controller 21, that is to say the flow rate of the heat transfer medium is reduced, and the fan for the air heater 37 is activated, so that now the energy generated via the fireplace 8 is supplied primarily to the air heater 37. Basically, it should be mentioned that the user via the control panel 40 other settings or inputs and information, such as room temperature setting, fan power, night setback, timer, level of the warehouse, etc., make or remove. The control panel 40 is preferably arranged on the outside of the power box 1.

Of course, it is also possible to provide additional connections in the power box 1 for the air heating 37 and rapid heating various other rooms, so that even rooms can be heated, which do not connect directly to the power box 1. Furthermore, it is possible to combine the controlled domestic ventilation 42 with it. The control is again via the control panel 40. The arrangement of the fan in the power box 1, the noise level is reduced to a minimum. It is also possible to transmit the combustion noise from the heating layer 11 to the outside in the living room by arrangement of speakers. Furthermore, in the interior 6 a Sprenkelanlage and smoke detector can be provided. In order to limit the temperature inside the box, heat can be dissipated via the draft chimney 19 via a draft regulator 44 and cool supply air can be supplied via the supply air pipe 22. It is also possible to use the air heating in the summer for dehydrating vegetables, fruits and herbs for drying. Of course, it is also possible to install a wall heating in the side walls 4.
