Description

[0001] The present invention relates to a hydraulic device for an energy distribution unit and / or an energy supply system, comprising at least one primary interface by means of which at least one primary side of a heat pump and / or at least one heat exchanger of the energy supply system can be connected to the hydraulic device. The invention further relates to an energy distribution unit, an energy supply system, and a method for constructing and / or commissioning an energy supply system.

[0002] From EP 4 033 163 A1, an energy supply system for providing cooling and / or heating capacity is known. The energy supply system comprises a hydraulic unit with a fluid interface for a heat pump, a fluid interface for a first heat exchanger, and a fluid interface for a second heat exchanger. Thus, the hydraulic unit is designed to connect the primary side of the heat pump to the respective heat exchangers. The secondary side cannot be connected. Therefore, a second hydraulic unit is necessary for the secondary side in order to connect a consumer to the heat pump. Furthermore, this hydraulic unit can only provide cooling if the heat pump is designed as a reversible heat pump and can therefore switch independently between heating and cooling modes.With a conventional heat pump, the disclosed hydraulic device can only be used for heating. Furthermore, the functionality of the disclosed hydraulic device is very limited, as it can only act on the primary side.

[0003] Alternatively, it is known from the prior art that hydraulic systems without interfaces can be installed and / or commissioned on-site at the consumer's premises. For this purpose, individual pipe sections are transported to the consumer and assembled on-site, creating a hydraulic system. These systems can be more complex in design. It is also conceivable that these hydraulic systems can be connected to both the primary and secondary sides of the heat pump. However, these have the disadvantage of not being transportable. The mechanical connection of the individual pipe sections to existing or purpose-built buildings is also complex. Furthermore, trained specialists are required for installation and commissioning at the consumer's site. Since local conditions often vary, a customized solution is always necessary.

[0004] The object of the present invention is to eliminate the disadvantages known from the prior art.

[0005] The problem is solved by a hydraulic device, an energy distribution unit, an energy supply system, and methods for creating and / or commissioning an energy supply system with the features of the independent claims. Advantageous or preferred embodiments or further developments of the invention are characterized by the features of the dependent claims.

[0006] A hydraulic system for an energy distribution unit and / or an energy supply system is proposed. The hydraulic system is preferably designed as a modular and / or transportable unit. The modular design allows for easy adaptation of the hydraulic system to various requirements and locations. This increases flexibility and simplifies installation. Transportability allows for prefabrication of the hydraulic system, so that it preferably only needs to be connected at the point of use. Preferably, the hydraulic system includes at least one primary interface. Using this primary interface, for example, at least one primary side of a heat pump and / or at least one heat exchanger of the energy supply system can be connected to the hydraulic system, particularly hydraulically and / or thermally.The primary interface ensures that an effective connection is established between the heat pump and the energy supply system.

[0007] Preferably, the hydraulic system additionally or alternatively comprises at least one secondary interface. This secondary interface allows a secondary side of the heat pump and / or at least one consumer and / or at least one buffer storage tank for the consumer to be connected to the hydraulic system, particularly hydraulically and / or thermally. The secondary interface enables efficient distribution of the generated energy to the at least one consumer, thus increasing the system's operating efficiency. The flexible design allows for the efficient integration of various types of consumers and any additional heat pumps that may be present.

[0008] Preferably, the energy supply system and / or the energy distribution unit comprises at least one heat pump and / or at least one consumer. Additionally or alternatively, the energy supply system comprises at least one heat exchanger.

[0009] Preferably, brine can be introduced into and / or discharged from the hydraulic system via the at least one primary interface and / or water via the at least one secondary interface. The hydraulic system is thus preferably designed as a brine-water hydraulic system. The use of brine and water as heat transfer fluids enables stable and efficient heat transfer. This leads to optimized system performance and reduced energy consumption. This makes it possible for both the primary and secondary sides of the heat pump to be connected to and / or operatively linked with the single hydraulic system.

[0010] It also offers advantages if at least one primary interface is designed as a detachable primary interface and / or at least one secondary interface is designed as a detachable secondary interface. The detachability of the interfaces facilitates maintenance, transport, and / or commissioning. Additionally or alternatively, this allows the hydraulic system to be manufactured in a production facility, particularly a series production facility, and then transported to the end user. Additionally or alternatively, it enables the easy replacement or expansion of components. This increases operational reliability and reduces system downtime.

[0011] Advantages arise if at least one primary interface is configured as a primary interface pair and / or at least one secondary interface is configured as a secondary interface pair, each with at least one flow and at least one return. The use of flow and return connections ensures that the heat transfer fluid can circulate efficiently in a closed loop.

[0012] It is advantageous if the hydraulic system includes at least one primary line section for connecting at least two primary interfaces and / or at least one secondary line section for connecting at least two secondary interfaces. These line sections allow for flexible connection of multiple components, enabling modular system expansion. This leads to easier system scalability and improves adaptability to different requirements.

[0013] It is also advantageous if the hydraulic system includes multiple primary and / or secondary pipe sections. Multiple pipe sections allow for the parallel flow of heat transfer fluids, which increases the flow rate and the overall heat transfer capacity. This improves the overall performance of the system.

[0014] Advantages arise when several of the primary pipe sections form at least one primary circuit and / or several of the secondary pipe sections preferably form at least one secondary circuit. The formation of primary and secondary circuits ensures a clear separation between different heat transfer systems, which increases efficiency. Furthermore, it creates the possibility of using different heat transfer fluids or temperatures in the respective circuits, thus increasing the system's flexibility.

[0015] It is also advantageous if the hydraulic system includes at least one heat exchanger, which allows thermal energy to be transferred between the at least one primary circuit and the at least one secondary circuit. The heat exchanger enables efficient energy transfer between the circuits, thus optimizing the use of thermal energy. This allows, for example, the heat pump to be switched off or throttled back in certain operating states of the energy supply system. For instance, heat transfer between the at least one primary circuit and / or the at least one secondary circuit can then occur without the heat pump. This can save the energy required to operate the heat pump in some applications.Additionally or alternatively, the provision of cooling capacity for the consumer can also be ensured with conventional heat pumps (without built-in cooling operation) with the help of at least one heat exchanger.

[0016] It is also advantageous if the hydraulic system comprises at least two secondary circuits, in particular a first secondary circuit and / or a second secondary circuit. The division into multiple secondary circuits allows for the targeted distribution of thermal energy to different consumers. Additionally or alternatively, a division between heating and cooling capacity is possible. For example, the first secondary circuit could be configured as a hot circuit and the second as a cold circuit. This allows for better regulation of the energy flow and / or adaptation to the specific needs of the consumer(s).

[0017] It is also advantageous if the at least one primary circuit, the at least one first secondary circuit, and / or the at least one second secondary circuit are hydraulically separated from each other and / or thermally coupled. Hydraulic separation enables independent control and / or regulation of the circuits. Simultaneously, thermal coupling enables efficient energy use through targeted heat transfer between the circuits, for example, with the aid of at least one heat exchanger.

[0018] It is also advantageous if the hydraulic system includes at least two heat exchangers, in particular a first heat exchanger and / or a second heat exchanger. With the aid of these at least two heat exchangers, thermal energy can be transferred between the primary circuit, the first secondary circuit, and the second secondary circuit. Using multiple heat exchangers optimizes heat distribution, resulting in higher energy efficiency. This leads to better adaptation to the different temperature requirements of the circuits. For example, the first heat exchanger can thermally connect the primary circuit to the first secondary circuit. Additionally or alternatively, the second heat exchanger can, for example, thermally connect the primary circuit to the second secondary circuit.

[0019] It is also advantageous if the hydraulic system includes at least one primary interface for the primary side of the heat pump. This primary interface enables a direct and / or efficient connection to the primary side of the heat pump.

[0020] It is also advantageous if the hydraulic system includes at least a second primary interface for a first heat exchanger of the energy supply system, which is particularly designed as a water heat exchanger and / or arranged in a latent heat storage unit of the energy supply system. The water heat exchanger can, for example, be arranged in the latent heat storage unit. Preferably, the latent heat storage unit is designed as an ice storage unit. The integration of a water heat exchanger enables the efficient use of water as a heat transfer medium, which is particularly advantageous for storing thermal energy. Preferably, the latent heat storage unit is designed to provide sufficient cooling and / or heating capacity during the day and / or night, so that the most economical operation of the energy supply system can be ensured. The second primary interface thus enables the connection of a water heat exchanger.

[0021] It is also advantageous if the hydraulic system includes at least a third primary interface for a second heat exchanger of the energy supply system, in particular one designed as an air heat exchanger and / or arranged in an air module of the energy supply system. The third primary interface thus enables the connection of an air heat exchanger.

[0022] It is also advantageous if the hydraulic system includes at least one primary secondary interface for the secondary side of the heat pump. This primary secondary interface ensures efficient transfer of the generated heat energy to the downstream system, thus optimizing energy flow and increasing overall efficiency.

[0023] Furthermore, it is advantageous if the hydraulic system includes at least one second secondary interface for a first buffer storage tank of the consumer, particularly one designed as a hot water storage tank, and / or for the consumer itself. The hot water storage tank can, for example, be used to supply the consumer with heating power. Preferably, the consumer and / or the energy distribution unit includes the at least one buffer storage tank, in particular the first buffer storage tank.

[0024] Advantages arise if the hydraulic system includes at least a third secondary interface for a second buffer storage tank, particularly a cold storage tank, belonging to the consumer and / or for the consumer itself. The cold storage tank can, for example, supply the consumer with cooling capacity. Preferably, the consumer and / or the energy distribution unit includes the at least one buffer storage tank, particularly the second buffer storage tank.

[0025] Using the aforementioned multiple primary and / or secondary interfaces, a highly complex hydraulic system can be disassembled at the system's boundary. This allows the entire hydraulic system to be prefabricated and transported to the point of use. On-site connection is thus significantly simplified, eliminating the need for specialized personnel.

[0026] It is also advantageous if the hydraulic system includes at least one control valve, particularly a butterfly valve and / or a 3-way control valve, and / or at least one pump. The control valve and / or pump enable precise control and / or regulation of the fluid flow within the system. This allows for flexible adaptation to different operating conditions and improves overall performance. The at least one control valve and / or the at least one pump preferably connect several primary and / or secondary pipe sections. This makes it possible to modify and / or regulate the brine and / or water flow through the individual pipe sections, particularly with the aid of a control system.The ability to control and / or regulate the fluid flow allows for efficient adaptation to the current heat demand, leading to a reduction in energy consumption and an extension of the service life of the system components.

[0027] It is also advantageous if the hydraulic system includes at least one shut-off valve, preferably adjacent to the at least one primary interface and / or the at least one secondary interface, and preferably to all primary and / or secondary interfaces. The shut-off valve allows for easy interruption of the fluid flow. This makes it possible to fill the hydraulic system before transport to the consumer. Additionally or alternatively, this prevents internal contamination of the hydraulic system during transport. Additionally or alternatively, this facilitates maintenance and / or the replacement of system components. The shut-off valve is preferably designed as a manually and / or mechanically actuated shut-off valve.

[0028] Additionally or alternatively, the hydraulic system preferably comprises at least one connecting flange, particularly adjacent to the at least one primary interface and / or the at least one secondary interface, preferably to all primary and / or secondary interfaces. The connecting flange provides a secure and / or leak-proof connection between different pipe sections. For example, the prefabricated hydraulic system can thus be easily connected to the consumer and / or the at least one buffer storage tank and / or the at least one heat exchanger.

[0029] It also offers advantages if the hydraulic system includes at least one hydraulic module. The hydraulic module compactly combines essential components of the hydraulic system, improving clarity and ease of use. This simplifies the installation and maintenance of the system.

[0030] It is also advantageous if the hydraulic system and / or at least one hydraulic module and / or several hydraulic modules of the hydraulic system are designed to be transportable, particularly independently of one another. This allows larger hydraulic systems to be divided into individual hydraulic modules and assembled on-site or at the customer's location. It thus appears possible for the individual circuits, especially the primary circuit, the first secondary circuit, and / or the second secondary circuit, to form independent hydraulic modules. This further simplifies transport and / or ensures the transportability of very large hydraulic systems. For example, the hydraulic system and / or the at least one hydraulic module can be moved into a transport position using the shut-off valve and / or adjusted between the transport position and an operating position.The modules' portability allows for flexible deployment and easy relocation of the system to different sites. This reduces logistical effort and facilitates the rapid setup of the system at new locations.

[0031] It is also advantageous if the hydraulic system and / or the at least one hydraulic module includes a frame. The frame accommodates the at least one primary interface, the at least one secondary interface, the at least one primary piping section, the at least one secondary piping section, the at least one primary circuit, the at least one secondary circuit, the at least one heat exchanger, the at least one control valve, the at least one pump, and / or the at least one shut-off valve. The frame ensures stable and / or secure mounting of several, in particular all, components of the at least one hydraulic module and / or the hydraulic system. This further simplifies transport and / or installation. The clear arrangement of the components within the frame also simplifies maintenance and component replacement.

[0032] It is also advantageous if the frame includes at least one connection section for the at least one primary interface, the at least one secondary interface, the at least one primary piping section, the at least one secondary piping section, the at least one primary circuit, the at least one secondary circuit, the at least one heat exchanger, the at least one control valve, the at least one pump, and / or the at least one shut-off valve. The connection section allows for flexible connection of the various components, which supports the modularity and expandability of the system. This leads to improved adaptability to different requirements and application scenarios.

[0033] It is advantageous if the frame is designed as an open or closed frame and / or if the frame comprises at least one brace, in particular a mounting brace, and / or at least one plate, in particular a cover plate. An open frame allows easy access to the components for maintenance and repairs, while a closed frame offers additional protection against external influences. The braces and plates increase the structural stability of the frame and provide additional mounting points and / or connection sections for the individual components of the hydraulic system.

[0034] Advantages arise if the frame is cuboid in shape and / or if a first edge length of the frame along a longitudinal direction of the hydraulic unit is preferably twice as long as a second edge length of the frame along a transverse direction of the hydraulic unit. The cuboid structure of the frame allows for a compact and space-saving arrangement of the components, which facilitates installation in confined spaces. The proportions of the frame contribute to optimal load distribution and ensure stability during transport and operation.

[0035] It is also advantageous if the hydraulic unit, particularly on the frame, comprises at least one stand and / or at least one connection side. The stand provides a stable base for the hydraulic unit on the floor, which increases stability and reduces vibrations. The connection side facilitates the connection of the various interfaces, simplifying the installation and operation of the system. Preferably, the frame includes a first connection side for the at least one heat pump. Preferably, the hydraulic unit also includes a first connection side for the at least one heat pump. Additionally or alternatively, the hydraulic unit includes a second connection side for the primary side of the heat pump, for the secondary side of the heat pump, for the first buffer tank, for the second buffer tank, and / or for the consumer.

[0036] It is also advantageous if the frame, especially if it is enclosed, is at least partially open in the connection area for at least one primary interface and / or at least one secondary interface. This partial opening in the connection area allows quick and easy access to the interfaces, which facilitates the installation, commissioning, and / or maintenance of the hydraulic system. This improves the system's usability and reduces downtime.

[0037] It also offers advantages if the hydraulic system includes at least one control / regulation unit. The control / regulation unit enables precise control, regulation, and / or monitoring of the hydraulic system's operation, which increases efficiency and optimizes energy consumption. Furthermore, the control / regulation unit allows for the automation of certain processes and / or operating states, simplifying operation and improving system stability.

[0038] Furthermore, an energy distribution unit for an energy supply system is proposed. Preferably, the energy distribution unit comprises at least one heat pump.

The hydraulic unit ensures a reliable connection between the various components of the system and enables a stable energy flow. The at least one hydraulic unit allows for the hydraulic connection of at least one heat exchanger, at least one heat pump, and / or at least one consumer.The hydraulic connection enables an efficient exchange of thermal energy, leading to a targeted and / or controlled distribution of the generated heating and / or cooling power in the system.

Additionally or alternatively, the heat pump and / or the at least one heat exchanger and / or the at least one consumer are designed according to the preceding description, wherein the aforementioned features may be present individually or in any combination. This allows for flexible adaptation and individual configuration of the hydraulic system as required, thus expanding the application possibilities of the energy distribution unit.

[0040] It is also advantageous if the power distribution unit includes at least one enclosure, particularly one designed as a container and / or building module. The enclosure protects the internal components from external influences such as weather or mechanical stress, thus increasing the system's service life and operational reliability. At the same time, the container design allows for modular and flexible installation at various locations. Additionally or alternatively, the power distribution unit could be designed to be transportable as a whole. This would further reduce assembly and / or commissioning efforts.

[0041] Furthermore, it is advantageous if at least one heat pump, at least one hydraulic unit, at least one buffer storage tank for the consumer, and / or at least one control unit are arranged within the housing. The control unit can be used, for example, to control and / or regulate the hydraulic unit, the heat pump, and / or the at least one buffer storage tank.

The external interface enables a simple and quick connection of the external components to the energy distribution unit. This simplifies installation and maintenance and increases the system's flexibility when integrated into various energy supply systems. Additionally or alternatively, the energy distribution unit could be modular. This would allow one or more energy distribution units to be used and / or connected to each other, depending on the application and / or consumer.

Integrating the components into an energy distribution unit provides a compact and space-saving solution that allows for easy installation and maintenance. This increases operating time and improves the overall efficiency of the system.

[0046] Furthermore, it is advantageous if the energy supply system includes several energy distribution units. Using multiple energy distribution units allows for system scalability, enabling flexible adaptation to varying power requirements. This contributes to improved system performance and allows for individual adjustment to the consumer's energy needs.

[0047] It is also advantageous if the energy distribution units are modular and / or, in particular, hydraulically and / or mechanically connectable. The modular design facilitates system expansion and adaptation by allowing for the easy integration of additional units.
