Description

[0001] The present invention relates to a functional unit for a modular energy generation system, comprising a pipe system with at least one fluid inlet and at least one fluid outlet, wherein the length of the pipe system through which a fluid can flow from the at least one fluid inlet to the at least one fluid outlet is greater than a linear distance between the fluid inlet and the fluid outlet. The invention further relates to a modular energy generation system comprising at least one functional unit. Technological background

[0002] Decentralized energy generation systems can make a significant contribution to achieving the goal of CO2 neutrality. The necessary energy transition is leading to a substantial increase in individual and, above all, new technologies. In this context, intelligent solutions with competitive costs are particularly in demand for industry and commerce.

[0003] The construction of decentralized energy generation systems is traditionally carried out as individual projects in separate phases of construction and building services engineering. Therefore, only a small degree of prefabrication is currently possible, resulting in a high proportion of on-site assembly and significant time expenditure for planning, tendering, construction, and commissioning.

[0004] Therefore, there is a need for modular and scalable energy generation systems that can overcome the aforementioned hurdles. Description of the invention: Problem, solution, advantages

[0005] The invention aims to provide a functional unit that reduces the effort and associated costs associated with the planning, construction, and commissioning of modular energy generation systems. Furthermore, the invention aims to provide a modular energy generation system.

[0006] To solve the problem, a functional unit for a modular energy generation system is proposed, comprising a pipe system with at least one fluid inlet and at least one fluid outlet, wherein a length of the pipe system through which a fluid can flow from the at least one fluid inlet to the at least one fluid outlet is greater than a linear distance between the fluid inlet and the fluid outlet, wherein it is further provided that the functional unit includes a holding device, and that the pipe system is attached to and supported by the holding device.

[0007] The functional unit serves for the space-saving and compact integration of functions provided in a modular energy generation system. A modular energy generation system is understood to be a device for generating energy, in particular heat or cooling. Such energy generation systems can be used, for example, to supply residential or commercial buildings or factories with energy, especially heat or cooling. The modular energy generation systems comprise standardized energy generation modules, for example, for energy, cooling, or heat generation, which can be combined as needed depending on the load profile of the facility to be supplied. Standardization enables cost-efficient and rapid planning and construction of the energy generation systems and offers the advantage of prefabrication. The standardized energy generation modules are connected to each other and to consumers via piping.

[0008] The piping system of the functional unit is designed such that the actual flow length is greater than the direct, linear distance between the fluid inlet and outlet. This can be achieved, for example, by a coiled, looped, or otherwise extended pipe routing. Since the length of the piping system through which a fluid can flow from the at least one fluid inlet to the at least one fluid outlet is greater than the actual distance required to bridge the gap between the fluid inlet and outlet, an additional length of pipe is provided. This extra length allows for the space-saving integration of further functions that are advantageous for a modular energy generation system.

[0009] The functional unit is preferably designed so that it can be integrated as a standalone component into a larger, modular energy generation system. The interfaces for the fluid inlet and outlet are designed to allow for easy connection to other modules or the piping of the modular energy generation system.

[0010] The functional unit reduces the piping of a modular energy generation system to its basic connection function. All components with additional functions – preferably with the exception of any safety devices required for energy generation modules – can be concentrated in the functional units, which can be prefabricated and always feature identical, defined interfaces for the piping.

[0011] The holding device serves to mechanically fix and support the pipe system. It can be designed, for example, as a frame, rack, or support structure to which the pipe system is attached. Attachment can be achieved using clamps, brackets, welded connections, or other suitable fasteners. The holding device ensures stable support for the pipe system and allows for easy assembly and disassembly of the functional unit within the modular energy generation system. The functional unit is designed to be self-supporting.

[0012] The pipe system of the functional unit is supported on the floor by means of the holding device.

[0013] Functional units can be provided in various nominal pipe diameters, with the different pipe dimensions being assigned to a specific functional unit using a unique grid dimension. The functional units are dimensioned to match the maximum nominal flow rate of the fluid.

[0014] The fluid is preferably water and also preferably serves as a heat or cold transfer medium in a modular energy generation system.

[0015] Preferably, the functional unit can have an overall length and / or overall width which is less than or equal to the length of the holding device and / or which is less than or equal to the width of the holding device and / or which is less than or equal to the linear distance between the fluid inlet and the fluid outlet.

[0016] This allows for a particularly space-saving and compact design of the functional unit. The compact design of the functional unit can especially facilitate integration into modular energy generation systems and enables flexible arrangement of multiple functional units within an overall system. The reduction in dimensions can be achieved, for example, through clever routing of the pipe system within the functional unit, so that despite a greater flow length through the pipes, the external dimensions of the functional unit remain small.

[0017] Furthermore, the compact design of the functional unit allows multiple units to be accommodated within a given installation space. This is particularly advantageous in the planning and implementation of modular energy generation systems, as it enables efficient use of available space. The pipe system's attachment to the mounting bracket can be designed to ensure the stability and load-bearing capacity of the functional unit even with reduced external dimensions.

[0018] The base area of ​​the functional unit can therefore be limited by the dimensions of the linear distance between the fluid inlet and the fluid outlet and / or the length or width of the holding device.

[0019] The functional unit can therefore be designed compactly and used as a largely standardized unit in modular energy generation systems. This can increase the predictability of energy generation systems and thus reduce their costs.

[0020] Preferably, the functional unit can be pre-configurable and / or prefabricated and / or transportable.

[0021] This makes it possible to fully or partially configure the functional unit before installation in the modular energy generation system. Pre-configuration can include, for example, the selection and arrangement of specific functional elements such as sensors, valves, or pumps. The functional unit can also be prefabricated in such a way that all components, including the piping system and mounting hardware, are already factory-assembled. This significantly reduces on-site installation effort and simplifies the commissioning of the modular energy generation system.

[0022] Furthermore, the functional unit can be designed to be portable. This means that the functional unit is manufactured in a manageable format, which allows for easy transport to the installation site of a modular energy generation system.

[0023] The functional unit can be designed as a universal connection assembly for a wide variety of energy generation modules within a modular energy generation system. This allows for the standardization and pre-configuration of these functional units. Such standardization facilitates integration into different systems and enables efficient series production as well as flexible adaptation to various requirements within modular energy generation systems.

[0024] Preferably, the holding device may be a rack and / or frame with several cantilever arms, with the pipe system attached to the cantilever arms.

[0025] The cantilever arms can be configured in various arrangements and lengths to ensure optimal support and guidance of the pipe system within the functional unit. The frame can be made of metal, plastic, or a combination of these materials and is preferably designed to guarantee high stability and load-bearing capacity. The pipe system can be attached to the cantilever arms using clamps, brackets, screw connections, or other suitable fasteners. By arranging the pipe system on multiple cantilever arms, flexible yet secure support within the functional unit can be achieved. Furthermore, this design allows for easy adaptation to different pipe configurations and lengths, thus meeting various functional requirements within modular energy generation systems.

[0026] The cantilever arms can be arranged at different levels or angles on the rack or frame to support a compact and space-saving integration of the pipe system. Furthermore, the rack or frame can be equipped with additional fixing points or guide elements to ensure secure fixation of the pipe system.

[0027] Optionally, the mounting device can be designed to allow for modular expansion or adaptation of the functional unit. For example, additional cantilever arms or fastening elements can be retrofitted to adapt the pipe system to changing requirements or system configurations.

[0028] Advantageously, the mounting device transforms the functional unit into a self-supporting structure. This eliminates the need for additional attachment of the pipe system to the walls of the modular power generation unit. The frame or support structure with its cantilever arms ensures overall mechanical stability and load-bearing capacity, allowing for flexible placement of the functional unit within the overall system. This significantly simplifies assembly and contributes to the efficient installation and maintenance of modular power generation systems.

[0029] Preferably, the pipe system of the functional unit can include at least one functional element.

[0030] Such a functional element can be, for example, a valve, a filter, a sensor, a flow meter, a temperature sensor, a pressure regulator, or another component used to control, monitor, or influence the flowing fluid. Integrating at least one functional element allows for additional tasks such as filtration, temperature control, pressure monitoring, or flow measurement to be performed within the functional unit. The selection and arrangement of the functional elements can be flexibly adapted to the specific requirements of the modular energy generation system.

[0031] The pipe system may comprise several functional elements arranged in series or parallel to one another. These functional elements can perform different tasks, thus expanding the functionality of the unit. The functional elements can be permanently integrated into the pipe system or designed as interchangeable modules to allow for flexible adaptation and maintenance.

[0032] The selection of functional elements, as well as their number and positioning within the pipe system, can vary depending on the application. It is also conceivable that certain functional units are designed without any functional elements, while others are equipped with a variety of different functional elements.

[0033] In addition, the functional unit can be configured according to requirements and type. Individual functions can be selected and configured accordingly, allowing them to be provided optionally and in different versions. Preferably, the functional elements are located at predefined and standardized positions within the functional units and / or always inserted in the same sequence. This allows for the creation of a standardized catalog of functional units from which suitable units can be selected depending on the configuration of the modular energy generation system. This enables flexible and efficient adaptation of the modular energy generation system to different requirements and simplifies the planning, assembly, and maintenance of the modular energy generation systems.

[0034] Preferably, the at least one functional element can be a shut-off valve, a pump, a temperature sensor, a pressure sensor, a control valve, a mixing valve, a sludge trap, a dirt trap, a heat meter, a check valve or a cold meter.

[0035] These functional elements can be arranged individually or in combination within the piping system to fulfill various tasks in the modular energy generation system. For example, a shut-off valve can be used to interrupt or regulate the fluid flow, while a pump can be used to circulate the fluid. A temperature or pressure sensor can be used to monitor operating parameters. Control valves and mixing valves enable the targeted control and mixing of fluid flows. Sludge traps and strainers remove solid particles from the fluid to increase the operational reliability and lifespan of the system. Heat meters and cold meters can be used to measure and monitor the energy transferred.

[0036] Furthermore, the functional elements can be check valves, temperature indicators, pressure indicators, as well as filling and draining ball valves. Preferably, the functional elements are arranged, sized, and functionally designed so that they can be used equally well for functional units for various energy generation modules, in particular for heat and cold generators.

[0037] It may be preferable that the functional elements are not safety devices, such as safety pressure relief valves, safety pressure limiters, safety temperature limiters, or expansion vessels. Such safety devices vary considerably depending on the energy generation module; for example, a biomass boiler requires different safety devices than a heat pump. In some cases, such safety devices are installed on the energy generation module. It may be possible to install safety devices that are not installed on the energy generation module in the piping between the functional unit and the energy generation module.

[0038] The selection and arrangement of these functional elements can be flexibly adapted to the specific requirements of the modular energy generation system. It is possible to combine several of these functional elements in a single functional unit to fulfill a variety of tasks within the system. The functional elements are preferably integrated at predefined positions within the piping system, ensuring a standardized and maintenance-friendly design of the functional unit. The functional elements can be permanently integrated into the piping system or designed as interchangeable modules to facilitate easy adaptation and maintenance.

[0039] Depending on the intended function of the functional unit, other functional elements may also be included. It is possible to select various functions or functional elements, whereby the selection of certain functional elements can automatically trigger further consequences that cannot be manually influenced, as these are pre-configured and stored. For example, selecting a pump may automatically insert a bypass and a 3-way mixing valve of the appropriate size at a predefined location. Conversely, if no pump is selected, a pipe section may be used instead of the bypass and the 3-way mixing valve. This automatic configuration enables efficient adaptation of the functional unit to different system requirements and simplifies the planning and assembly of the modular energy generation system.

[0040] It is particularly preferred that the at least one fluid inlet and the at least one fluid outlet are arranged vertically above the pipe system.

[0041] This means that the connection points to the piping of a modular energy generation system for the fluid inlet and outlet can be located vertically above the actual course of the functional unit's piping system. Such an arrangement makes it possible to route the piping system within the functional unit below the fluid inlet and outlet.

[0042] Routing the pipe system below the fluid inlet and outlet allows for additional pipe length to be accommodated within the functional unit without significantly increasing its external dimensions. This can be particularly advantageous when multiple functional elements are to be integrated within the unit or when a specific minimum pipe system length is required for the desired functionality.

[0043] The term "vertical" refers to the intended installation position of the functional unit within a modular energy generation system. In the case of piping running along the ceiling of a modular energy system, for example, the functional unit's pipework can extend downwards out of the piping plane. The installation of the functional unit thus creates a downward loop of pipe, which is then routed back upwards to the piping. This creates additional pipe length that can be used for integrating further functions within the modular energy generation system.

[0044] Furthermore, the pipe system can comprise at least one pipe string. It is particularly advantageous for the pipe system to have two pipe strings, in particular a first pipe string and a second pipe string. These two pipe strings can, for example, be arranged parallel or in different planes within the functional unit. It is also possible for the two pipe strings to be fluidically connected to each other via a pipe connection. Such a connection can, for example, be designed as a cross connection, a bridging connection, or a bypass.

[0045] A fluidic connection is understood to be, in particular, a fluid-conducting connection.

[0046] By arranging multiple pipe sections within the pipe system, the functional unit can perform additional tasks, such as implementing supply and return lines, integrating bypass lines, or enabling switching functions between different operating modes. Furthermore, the multi-pipe design allows for the integration of different functional elements into the respective sections, thus further enhancing the functionality of the unit.

[0047] Each pipe string can have its own fluid inlet and fluid outlet.

[0048] Preferably, the pipe system, in particular the first pipe string and / or the second pipe string, can be essentially U-shaped.

[0049] Such a U-shaped design of the pipe system offers the possibility of increasing the length through which a fluid flows within a limited installation space without significantly increasing the external dimensions of the functional unit. It is conceivable that either only one or both pipe strands could have an essentially U-shaped geometry.

[0050] Preferably, the at least one fluid inlet may be arranged in a first plane, and the at least one fluid outlet may be arranged in a second plane, with the first plane being arranged above or below the second plane.

[0051] The first and second levels are horizontally aligned in the installation position of the functional unit within a modular energy generation system. This means that both the fluid inlet and the fluid outlet are arranged in horizontal planes that differ in height. This can be particularly advantageous when integrating the functional unit into systems with ceiling-mounted piping.

[0052] The arrangement of fluid inlet and fluid outlet at different height levels can be particularly advantageous when different connection or piping levels are to be used within a modular energy generation system.

[0053] Furthermore, arranging the fluid inlet and outlet on different levels can help avoid pipe crossings and simplify piping installation within the modular power generation system. Designing the functional unit with fluid inlet and outlet on different levels can also facilitate maintenance, as the connection points are more accessible and a clear separation of flow paths is ensured.

[0054] If the piping system comprises two or more pipe strings, it can be arranged that a fluid inlet of a first pipe string is located in a first plane, and that a fluid outlet of the first pipe string is located in a second plane, and that a fluid inlet of a second pipe string is located in the second plane, and that a fluid outlet of the second pipe string is located in the first plane. The first plane can then be located above or below the second plane.

[0055] Another solution to the problem consists of a modular energy generation system comprising at least one energy generation module and at least one previously described functional unit.

[0056] The energy generation module is designed to provide energy, particularly in the form of heat or cold. The functional unit is preferably fluidically connected to the at least one energy generation module and performs specific tasks and functions within the modular energy generation system, such as controlling, regulating, or monitoring the flowing fluid. As explained above, the functional unit comprises a pipe system with at least one fluid inlet and at least one fluid outlet, wherein the pipe system is attached to and supported by a mounting device. The length of the pipe system through which the fluid flows is greater than the linear distance between the inlet and outlet, thus providing additional pipe length for the integration of functional elements within a compact installation space.

[0057] Compared to conventional energy generation systems, which are often built as individual projects in separate lots within the construction and building services engineering (BSE) trades, the modular energy generation system offers significant advantages. Conventional systems typically involve a low degree of prefabrication and a high degree of on-site assembly, resulting in considerable time expenditure for planning, tendering, construction, and commissioning.

[0058] Integrating at least one functional unit into the modular energy generation system allows for the standardization of the system's design and manufacturing. This leads to cost reductions and significantly shortens the time from planning to completion.

[0059] The connection between the energy generation module and the functional unit is preferably made via standardized interfaces, so that simple and flexible integration of several energy generation modules and functional units within the overall system is possible.

[0060] The modular energy generation system is designed to offer high flexibility and scalability. Its modular construction allows individual energy generation modules and functional units to be combined as needed. The standardized design of the functional units and their interfaces enables efficient planning, assembly, and maintenance of the overall system. The functional units are designed to be preconfigurable, prefabricated, and transportable, which significantly simplifies the installation and commissioning of the modular energy generation system.

[0061] Preferably, the at least one energy generation module of the modular energy generation system can be designed as a combined heat and power plant, as at least one fuel cell, as a heat pump, as a chiller, as an electric boiler or as a bioenergy generation unit.

[0062] The selection of the respective energy generation module(s) can be flexibly adapted to the requirements of the specific application. A combined heat and power (CHP) plant, for example, enables the simultaneous generation of electricity and heat in a coupled process. A fuel cell can be used for the efficient conversion of chemical energy into electricity and heat. A heat pump is particularly suitable for utilizing ambient heat for heating purposes, and a chiller is suitable for providing cooling. A bioenergy generation unit can be used for the energetic utilization of biomass and thus contribute to a sustainable energy supply.

[0063] The aforementioned energy generation modules can be used individually or in combination within the modular energy generation system. This makes it possible to adapt the system to different supply requirements and conditions. The integration of various energy generation technologies within a modular system enables high flexibility and scalability, as well as the use of different energy sources.

[0064] The bioenergy generation unit can be designed, for example, as a pellet boiler, wood chip boiler, or wood chip boiler. These designs allow the use of various biogenic fuels and thus offer a wide selection of sustainable energy sources.

[0065] Furthermore, the modular energy generation system can optionally include hydraulic assemblies for grouping different energy generators or chillers. Similarly, routing modules can be provided for piping, enabling flexible and efficient connection of the individual energy generation modules and functional units. Space modules, tailored to the functional units and energy generation modules, can also be part of the system, supporting optimal space utilization and easy integration of the energy generation modules and functional units.

[0066] Furthermore, the modular energy generation system may also include modules that are not water-based. Examples include batteries for storing electrical energy, compressed air generators for providing compressed air, or steam generators for producing steam. Such modules expand the application possibilities of the modular energy generation system and enable even more versatile use in different fields.

[0067] Furthermore, the modular energy generation system can include piping, wherein the at least one functional unit and the at least one energy generation module are fluidically connected to each other via the piping.

[0068] The piping can be designed as a network of pipes that enables the transport of a fluid, such as water, between the various components of the system. It is conceivable that the piping consists of metallic or non-metallic materials and includes both rigid and flexible pipes.

[0069] Furthermore, the piping can be designed to allow for the modular and flexible connection of additional functional units or energy generation modules. The connection between the functional units and the energy generation modules or the piping can be achieved, for example, via standardized couplings, flanges, or quick-connect fittings to facilitate easy assembly, disassembly, or expansion of the system. In a further embodiment, the piping can be configured with separate lines for the supply and return, enabling targeted control and regulation of the fluid flows within the modular energy generation system.

[0070] Furthermore, the piping can be equipped with additional components such as shut-off valves, check valves, measuring points, or venting devices to facilitate system operation and maintenance. It can also be designed to run on multiple levels or at different heights to ensure optimal space utilization and a clear, organized installation.

[0071] Furthermore, it may be stipulated that at least one energy generation module has predefined standard dimensions and / or standard connections.

[0072] For example, the energy generation modules can be designed to meet specific, predefined dimensions, thus enabling easy integration into the modular energy generation system. The use of standard dimensions can, in particular, facilitate the interchangeability and combinability of different modules and simplify the planning and assembly of the overall system.

[0073] The energy generation module can be equipped with standardized connection points. These standard connections can include, for example, standardized pipe fittings, electrical connectors, or interfaces for control signals. Providing standard connections allows for quick and easy connection of different modules without the need for complex modifications. This contributes to the high flexibility and scalability of the modular energy generation system.

[0074] It is also conceivable that the standard dimensions and / or standard connections are aligned with industry-standard norms, allowing modules from different manufacturers to be easily integrated into the system. Establishing such standards can help shorten delivery times and reduce the costs of planning, manufacturing, and assembly.

[0075] Furthermore, the standard dimensions and / or standard connections may be selected to enable optimal space utilization within the modular energy generation system. For example, the energy generation modules may be dimensioned to fit into predefined grid dimensions of room modules.

[0076] Designing energy generation modules with predefined standard dimensions and / or standard connections thus represents an advantageous way to further increase the modularity, flexibility and efficiency of modular energy generation systems.

[0077] Furthermore, one solution to the problem consists of providing a storage medium on which a large number of data records are stored, wherein at least two of the data records relating to configuration data each comprise a previously described functional unit.

[0078] The storage medium is, in particular, an electronic and / or digital storage medium. The storage medium can be volatile or non-volatile, for example, a hard drive, a CD, a USB flash drive, or random access memory (RAM).

[0079] Preferably, the configuration data of different datasets relate to different configurations of the functional units. The functional units can differ in terms of the number of pipe runs, the selection, number and arrangement of functional elements, the nominal pipe diameters and / or the grid dimensions.

[0080] Another solution to the problem concerns a computer-implemented method for configuring a modular energy generation system comprising at least one energy generation module and at least one functional unit. The method includes the steps of creating at least one predicted load profile for an object to be supplied with energy and, using this load profile, creating at least one configuration of a modular energy generation system. For creating the configuration, at least one functional unit as described above is selected, comprising a pipe system with at least one fluid inlet and at least one fluid outlet, wherein the pipe system is attached to and supported by a holding device.

[0081] As part of the process, a load profile is first created for the building to be supplied. This load profile can be predicted based on historical consumption data, user information, building characteristics, weather data, or other relevant parameters. The load profile describes the expected energy demand of the building over a defined period and can include both thermal and electrical loads. The load profile can be predicted using suitable algorithms, such as statistical methods, machine learning, or simulation-based approaches.

[0082] Subsequently, at least one configuration of a modular energy generation system is generated using the created load profile. This process determines the components of the modular energy generation system required to meet the forecasted energy demand. In particular, at least one functional unit is selected whose design, dimensioning, and functionality are tailored to the determined load profile. The selection of this at least one functional unit is made to optimally meet the energy supply requirements of the building. The configuration can encompass the number and type of functional units as well as their arrangement and interconnection within the modular energy generation system.

[0083] The process can further include automated, computer-aided selection and configuration of the functional units. For this purpose, a software solution can be used that proposes a suitable system architecture based on the load profile and predefined system parameters. The configuration can then be iteratively optimized to maximize, for example, energy efficiency, operating costs, or system flexibility. The resulting configuration can serve as the basis for the planning, design, and implementation of the modular energy generation system.

[0084] Preferably, the selection of at least one functional unit is made by selecting a data set stored on a storage medium described above.

[0085] The selection of functional units is preferably made from a predefined catalog of preconfigured functional units. These functional units are standardized with regard to their technical properties, dimensions, and interfaces, and can be selected as needed according to the determined load profile. This enables an efficient and targeted assembly of the modular energy generation system.

[0086] Similarly, the energy generation modules can be selected from a predefined set of modules and combined as needed. The selection and combination of modules depends on the requirements of the respective load profile and the specific conditions of the building to be supplied. The use of standardized and pre-configured modules further increases the flexibility, scalability, and efficiency of the configuration process. Brief description of the drawings

[0087] Preferred embodiments of the invention are explained with reference to the accompanying figures. Fig. Figure 1 shows a functional unit with a pipe system and a holding device, Fig. 2 shows a pipe system of a functional unit, Fig. Figure 3 shows a pipe system of another functional unit, Fig. Figure 4 shows a perspective view of a modular energy generation system, Fig. Figure 5 shows a side view of a modular energy generation system, and Fig. Figure 6 shows a flowchart for a computer-implemented procedure for configuring a modular energy generation system. Detailed description of the characters

[0088] In the figures, identical or corresponding elements are marked with the same reference symbols.

[0089] Fig. Figure 1 shows a functional unit 100 for one in the Fig. 4 and Fig. 5 modular energy generation system shown 200.

[0090] The functional unit 100 comprises a pipe system 10 with fluid inlets 11 and fluid outlets 12. The pipe system 10 is designed to carry water for the transfer of energy in the form of heat or cold. Accordingly, the fluid is water. The length 13 of the pipe system 10 through which the fluid can flow from the fluid inlets 11 to the fluid outlets 12 is greater than the linear distance 14 between the fluid inlets 11 and the fluid outlets 12. The functional unit 100 includes a holding device 15 to which the pipe system 10 is attached.

[0091] The pipe system 10 comprises a first pipe string 16 and a second pipe string 17, which are essentially U-shaped. The first pipe string 16 and the second pipe string 17 are fluidically connected to each other via a pipe connection 18.

[0092] In functional unit 100, the fluid inlets 11 and the fluid outlets 12 are arranged vertically above the pipe system 10. Due to this design, the length 13 of the pipe system 10 through which the fluid can flow is greater than is required to bridge the actual distance between the fluid inlets 11 and the fluid outlets 12. The additional pipe length thus provided can be used for the space-saving integration of functions advantageous for a modular energy generation system 200. For this purpose, the pipe system 10 includes functional elements 19, for example, in the form of a pump 20, a mixing valve 21, a check valve 38, a strainer 39, and a heat meter 40.The functional unit 100 can be pre-configured for use in a modular energy generation system 200 as required and can therefore also include further functional elements 19, not shown here, such as a sludge trap or a cold quantity meter, as needed.

[0093] The holding device 15 is designed as a frame 22 with several cantilever arms 23, the pipe system 10 being attached to the cantilever arms 23. This makes the functional unit 100 a self-supporting unit. The functional unit 100 also has a total width 24, which corresponds approximately to the width 25 of the holding device 15. A total length 26 of the functional unit 100 corresponds approximately to the length 27 of the holding device 15. The functional unit 100 is designed to be correspondingly compact with a predetermined grid dimension. The functional unit 100 is also preconfigurable, prefabricated, and transportable.

[0094] Fig. Figure 2 shows the pipe system 10 of the functional unit 100. Fig. 1 without the holding device 15.

[0095] Fig. Figure 3 shows a further embodiment of a functional unit 100, where, for better clarity, also in Fig. 3. The holding device 15 is not shown. Also, the functional unit 100 of the Fig. 3 comprises a pipe system 10 with fluid inlets 11 and fluid outlets 12, which are arranged above the pipe system 10. The pipe system 10 also has a first pipe string 16 and a second pipe string 17, which are essentially U-shaped. Compared to the functional unit 100 of the Fig. 1 and Fig. However, the pipe system 10 includes another functional element 19 in the form of another pump 28.

[0096] In the functional units 100 of the Fig. In sections 1 to 3, the fluid inlet 11 of the second pipe string 17 is located in a first level 29 and the fluid outlet 12 of the second pipe string 17 is located in a second level 30, whereas the fluid inlet 11 of the first pipe string 16 is located in the second level 30 and the fluid outlet 12 of the first pipe string 16 is located in the first level 29. The first level 29 is located above the second level 30. This allows for the avoidance of 200 pipe crossings when integrating the functional units 100 into a modular energy generation system.

[0097] Fig. Figure 4 shows a modular energy generation system 200 in a perspective view. Fig. Figure 5 shows a side view of the modular energy generation system 200. The modular energy generation system 200 comprises energy generation modules 31 and functional units 100. The functional units 100 and the energy generation modules 31 are fluidically connected to each other via piping 32 of the modular energy generation system 200. In the illustrated configuration, the energy generation modules 31 comprise a combined heat and power plant 33, an air-cooled chiller 34, and a bioenergy generation unit 35 in the form of a pellet boiler 36. A pellet storage facility 37 is associated with the pellet boiler 36. The energy generation modules 31 have predefined standard dimensions, which can, for example, correspond to the dimensions of ISO containers.

[0098] Due to the modularity provided by the standardized functional units 100 and energy generation modules 31, the costs and time required for planning, construction, and commissioning of the modular energy generation system 200 can be significantly reduced. A computer-implemented method 300 can be used to configure such a modular energy generation system 200 for this purpose.

[0099] Fig.Figure 6 shows a flowchart for such a procedure 300. The procedure 300 includes a first process step S1, in which at least one predicted load profile is created for an object to be supplied with energy, such as a commercial property. In a second process step S2, at least one configuration of a modular energy generation system 200 is created using the at least one predicted load profile. In process step S2, the configuration creation process involves the computer-aided selection of at least one functional unit 100 and one energy generation module 31.

[0100] The load profile can be predicted, for example, based on historical consumption data, user information, building characteristics, weather data or other relevant parameters, and describes the expected energy demand of the building over a defined period.

[0101] The at least one functional unit 100 is selected so that its design, dimensions, and functionality are tailored to the determined load profile. A predefined catalog of preconfigured functional units 100 can be used as the basis for selecting the at least one functional unit 100. This enables an efficient and targeted assembly of the modular energy generation system.
