Description

The present description deals with an operating unit with functional groups, piping and electrical/electronic functional modules as well as wiring in a spatial arrangement in a mobile cabinet unit for combinable fluid-supported operation of a heat pump system, a solar thermal system and a solid fuel system.

The functional components for operating such systems are known. They are regularly installed in or outside of buildings to be heated and are technically coordinated with one another. They are used for the thermal utilization of heat provided by heat generators/heat exchangers. Such heat generators can be, for example, an outdoor air/water heat pump in a monoblock design, which provides heat from the ambient air, e.g. by means of a refrigeration unit installed in the outdoor unit.

It has often proven to be advantageous if, in addition to generating heat via a heat pump, a combination of several heat generators or heat generator systems is made available. So it is common that, in addition to the functional components for the heat pump operation, those for a solar thermal system as well as those that, for example, for the utilization of heat from a water-based stove are used in parallel and in combination.

Since heat in a house is not constantly in demand, but demand-based, and heat cannot be provided uniformly at all times by the heat generators, the systems mentioned are regularly operated with a stratified heat storage tank in the form of a heating buffer storage tank. The heating buffer storage serves as a heat buffer that stores the heat and via which the heat can then be accessed flexibly when it is needed. If the service water is also heated by means of a stainless steel heat exchanger within the heating buffer storage tank, this is also referred to as a so-called multifunctional or hygienic storage tank, which can not only absorb the heat generated by a heat pump, but can also be equipped with a heat exchanger, for example, via which heat from a solar thermal system can be extracted is recordable and at the same time a water-based stove is included.

The generation of heat via different heat generator systems, including the storage and removal of the heat obtained in this way via a stratified heat storage tank, leads to a significantly higher complexity in terms of control and structure than with previous heating systems without regenerative components, such as with gas heating as the sole heat generator case was.

The effort and the required know-how for the installation of such systems is therefore considerably greater, with safe operation primarily depending on the necessary requirements and regulations being observed during installation. The safe operation of these systems therefore largely depends on the competence of the person(s) installing the system. Skilled staff, which is often not available. It can already be seen today that the significantly greater complexity of a heat pump system leads to planning and installation errors.

A typical and frequent error is, for example, the wrong choice of cable cross-sections. As a result, this regularly leads to volume flows that are too low in the heat pump circuit. If the pipes are dimensioned as in a gas heating system, the pressure loss in the pipe network will be very high due to the then too small pipe cross-section at higher flow rates due to a lower flow temperature. As a result, the pressure generated by the circulating pump installed in the internal unit of the heat pump is no longer sufficient to maintain the required volume flow, which means that the pressure in the heat pump’s cooling circuit increases critically because the heat produced is no longer sufficiently transported away by the heating water can be. The result is a failure of the refrigeration circuit due to excessive pressure.

Furthermore, it has been found to be problematic that the complex system consisting of a large number of functional components currently requires considerable space for installation, so that such systems cannot be installed and therefore cannot be considered for this reason alone. Because space is often scarce in buildings because it is expensive.

There is therefore a need for simplification with regard to the installation of combined regenerative heat generation and operating systems that can be placed and connected in buildings in a compact and simple manner.

An object of an embodiment of the present invention can therefore be seen as creating a possibility that is space-saving, easy and safe to install for heat supply from in particular regenerative heat generation units and at the same time allows an efficient, reliable supply of heat or thermal energy.

Connection points for operating the heating system can be, for example, connection points for heat consumption and the cold and/or hot water supply.

By providing, according to the invention, all the functional groups required for heating operation of a heating system with heat from different heat generation units in a mobile cabinet unit in a spatially optimized arrangement according to the invention, an operating unit that is easy to place and install in a simple and error-minimizing manner is created for the first time, which in the sense of plug-and-play without pronounced Specialist knowledge of operating a heating system with different heat generator units can be used and connected.

With the advantageous spatial structuring of the arrangement spaces according to the invention and the arrangement according to the invention of the functional groups in the cabinet unit according to the invention and the arrangement spaces, it is also very advantageously possible to provide the connection points on the narrow side walls and the roof side wall, whereby the connection points in the erected state of the Cabinet unit on a partition for the operation of the heating system with the heat generator units are functionally freely and easily accessible connectable.

Buildings in the sense of the invention are in particular those whose room heights and/or doorways are designed in accordance with standards, in particular DIN-compliant, or those in which at least the functional space for the cabinet unit is standard and/or DIN-compliant in terms of room height and accessibility, or those in which at least the functional space has dimensions in terms of room height and accessibility, so that the cabinet unit can be set up in the functional space without the aid of tools depending on the size and dimensions of the cabinet unit. The latter can e.g. apply to a single-family house.

An advantage, particularly with regard to ease of installation, can also be that the connection points for the narrow side walls are provided in a half of the narrow side walls formed by a wall surface axis of symmetry, which half faces the rear side wall.

The same applies to the connection points for the roof side wall, with the connection points being provided in a half of the roof side wall formed by a wall surface symmetry axis, which half faces the rear wall and/or one of the narrow side walls

An advantageous development provides that the connection points contain a group of memory connection points for connecting a memory unit, the memory connection points being provided in and along one of the narrow side walls of the cabinet unit.

Provision can also advantageously be made according to the invention for the memory connection points to be provided vertically one above the other or vertically offset one above the other along the narrow side wall, in such a way that their vertical arrangement can be associated with corresponding connection points on the memory unit.

Not only does the orderly provision of the memory connection points on one side along one of the narrow side walls lead to simpler connection of the operating unit according to the invention, but this is also improved to a greater extent by the fact that the memory connection points can also be aligned in terms of height with the memory unit, because the relevant storage units are often so-called stratified heat storage systems, which make it necessary for heat to be obtained only from certain altitude layers or for fluid heat to be fed only into certain fluid heat layers of the stratified heat storage tank so that the separation between the fluid heat layers in the stratified heat storage tank is not disturbed or destroyed . The fluid connection flanges to the storage unit are therefore often assigned in terms of height to the different temperature layers of the stored fluid and are arranged correspondingly in terms of height. Furthermore, this leads to a reduction in the consumption of the tube and at the same time to a minimization of thermal tube transition areas or thermal losses.

2 shows a side view of the operating unit B according to the invention from the left, specifically without the left narrow side wall 103-1, so that the inside of the operating unit B can be viewed. while showing 2 schematically from the side the functional groups and their functional elements as in connection with 1 described as well as the spatial distances 410 and 210 of the functional elements.

The space distances 410 define, among other things, the tube center space 411, which runs at a distance from and along the rear side wall 101, the top side wall 104 and the narrow side walls 103-1 and 103-2.

The spatial distances 210 define the functional module space 211 for arranging the electrical functional modules 201, 202, 203 and 204.

The functional group space is located between the central pipe space 411 and the functional module space 211 . The spatial distances to the functional groups or functional elements are smaller due to the spatial distribution of the functional groups/functional elements in the cabinet unit 100 different sizes. This results in a structured central-relative three-dimensional arrangement of the functional elements/functional groups in the cabinet unit 100 .

In particular, this spatial arrangement provides the pipe means 400 with the necessary space or freedom of space inside the cabinet unit 100, so that they can be guided out of the cabinet unit 100 via connection openings 106 in a targeted manner and in particular with regard to the units or external units to be connected, it being possible to ensure according to the invention that the pipe means 400 have the required flow cross-sections for the intended use and that the pipe means 400 contain externally easily accessible and connectable connection points 106, the connection points 106, e.g can, so that a particularly simple connection of such a stratified heat accumulator 700 is possible (see 5 and 6 )

3 shows one to 2 comparable view. Among other things a difference to 2 is that out 3 the course of the middle of the tube, in particular along or parallel to the left-hand narrow side wall 103-1, can also be seen. Furthermore, one can use 3 Recognize fastening rails 500 for fastening functional groups/functional elements in the cabinet unit 100. Wiring means 600 can also be seen there in the form of bundles of cables, via which the functional elements receive electrical power and control signals can be exchanged. You can also see in 3 Connection points, namely connection points 1-4 above the roof side wall 104 and along the left 103-1. For the rest, the functional elements according to 3 according to those 1 and 2 , where the connection points in detail still in connection with 5 and 6 are described.

Connection openings 106 can be seen in the side walls, through which the pipe means 400 are routed to the connection points 1 to 24 to the outside. It can be seen in particular on the left narrow side wall 103-1 that the connection openings 106 are arranged vertically one above the other, so that the pipe means 400 guided through the connection openings 106 are provided at a height as far as possible so that they can easily be combined with one another Stratified heat accumulator 700 ( 7 ) guided connecting pipes can be connected.

How 4 as can be seen, the connection openings 106 always run in one half of the respective side wall 104, 103-1 and 103-2, which faces the rear wall side 101.

Construction and positioning of the functional modules and functional groups are within the operating unit according to the invention.

By using a cabinet unit with the rear wall 101, the two narrow side walls 103-1, 103-2 and the door side wall 102 as installation surfaces, an extremely compact, three-dimensional installation space is created in which everything for operating an air/water heat pump system in connection with e.g. a heating-supporting solar thermal system as well as a e.g.

As a result, the overall installation develops from the usual large-scale, two-dimensional wall installation in the boiler room of the building to a very compact form of installation that remains transportable due to its size. This innovative placement and combination of the individual components in the cabinet unit 100 according to the invention gives the installation completely new attributes.

Due to the compact cabinet installation, the operating unit B is transportable and can be transported by the heating installer to any desired installation location. While conventional systems have to be planned, dimensioned and permanently installed on site in the installation room, these work steps are taken over during the production of the operating unit B according to the invention. Due to the arrangement of the functional groups and functional modules in space, the routing of the pipe means can be effectively shortened. This saves raw materials because less pipe material is used. Furthermore, this increases the efficiency of the overall system with an integrated operating unit B according to the invention, since the heat losses through the pipelines are minimized. Due to the pipelines/pipes 400 already prepared in the operating unit B according to the invention, which are matched to the volume flow of the heat pump 301-1 used, volume flow-related failures no longer occur. One of the most common sources of error is thus avoided by the high degree of pre-equipment of the operating unit B according to the invention.

Due to the fact that in the operating unit B according to the invention, an automatic heating filling and refilling unit 305-1 for the treatment of the heating filling water is installed in accordance with VDI 2035, which according to DIN EN 1717/DIN 1988-100 also has the prescribed system separator, the system is always filled with water that has been treated in accordance with the standards. Reductions in performance or system damage as a result of system filling with incorrect or untreated water are thus ruled out. The operating unit B according to the invention already has all the essential safety devices installed internally.

The operating unit B according to the invention can be connected to any on-site heating and hot water installation and, as a central unit, supplies all connected consumers with the required thermal energy as required.

Subsequent operating states can in particular be mapped by the operating unit B according to the invention.

i: Heat pump operation

The central component of the operating unit B according to the invention is the thermal function group, which in particular can contain an air/water heat pump 301 - 1 and which is positioned in the upper right area of the cabinet unit 100 .

It contains the storage tank charging pump 301-1, which is responsible for transporting the heat from the outdoor unit/heat exchanger unit of the heat pump system to the stratified heat storage tank/hygienic storage tank 700. It also contains a control unit for the heat pump 301-1, so that the heating operation is defined based on the outside temperature in accordance with a heating curve stored for a building. The target service water temperature is also stored in the control unit.

The piping of the flow and return 12, 13 of the outdoor unit of the heat pump 301-1 and the flow e and return d to the hydro box 301-2 are made with 32x3mm metal composite pipe. The pipes from the Hydrobox 301-2 to the outer wall have the same pipe dimensions. The pre-assembled lines for connecting the stratified heat accumulator 700 to the operating unit B according to the invention are made of stainless steel corrugated pipe DIN25 and are already provided with the appropriate connections. Only the connection of the flow and return connection 12, 13 of the operating unit B according to the invention to the outdoor unit/heat exchanger unit of the heat pump system must be dimensioned individually according to the distance between the operating unit B according to the invention and the outdoor unit.

This dimensioning, in conjunction with the head of the heating circulating pump provided for the heat function group 301, ensures that the minimum volumetric flow of the outdoor unit prescribed by the manufacturer of the heat pump 301-1 is provided at all times. This rules out a malfunction of the heat pump 301-1 due to the volume flow.

Depending on the storage tank temperatures measured in the upper and lower area of the stratified heat storage tank 700 and the setpoint temperatures stored in the control unit of the heat pump 301-1, the heating or service water mode of the heat pump 301-1 is triggered. If one of the two minimum temperatures stored in the control unit is fallen below, the heating circulating pump of the heating function group is started and the heat pump process in the outdoor unit is started. In order to prevent the stratified heat accumulator 700 from cooling down due to the cool heating water in the lines, the flow and return 12, 13 of the heat pump 301-1 are short-circuited via a 3-way switching valve of the hydrobox 301-2. In the first step, only the water in the pipes between the outdoor unit and the operating unit B according to the invention is heated and the flow temperature is brought to the level of the storage water in the respective part of the stratified heat storage device 700 . Only then does the 3-way valve in the Hydrobox 301-2 switch over to the respective accumulator section and accumulator charging begins.

If there is a request via the service water temperature sensor, the upper storage area of the stratified heat storage tank 700 is loaded. If there is a request via the external return temperature sensor, which is positioned in the lower area of the storage tank, a second switching valve within the hydrobox 301-2 switches to the lower storage area. After reaching the respective target value in the stratified heat accumulator 700, the loading process of the stratified heat accumulator 700 is terminated. Here, domestic water heating has priority over a heating request. If there is a demand for domestic hot water while the heat pump is in heating mode, heating mode is interrupted and the control unit switches to the upper storage area. As soon as the domestic hot water requirement is met, the controller switches back to the lower storage area via the Hydrobox 301-2 and continues the interrupted heating operation until the requirement is met.

The heat pump unit is mono-energetically designed to solely cover the total heat requirement. The secondary heat generator (heating element) required for this is already installed in the internal unit of the heat pump 301-1. The heating curve of the building, the dual mode temperature and the controller setting for mapping the hydraulics of the heating system are preset in the control unit so that the system is ready for operation after installation is complete without any further settings.

ii: solar power

The control of a solar thermal system is also taken over by the control unit of the heat pump 301-1. The regulator/control module 201, which is mounted on the left-hand side wall of the door 102-1, is required as an interface for this. It is a temperature difference control that compares the collector temperature of a collector unit of the solar thermal system with the temperature in the stratified heat storage tank 700 at the level of an integrated solar heat exchanger.

As soon as the collector temperature exceeds the storage tank temperature by 8 °C (standard switch-on hysteresis), a solar pump is switched on by the control unit and the stratified heat storage tank 700 is loaded. As soon as the temperature difference falls below 4 °C (standard switch-off hysteresis) or the maximum storage tank temperature is reached, the solar pump unit 302-1 is switched off. A high-efficiency solar pump is installed in the solar pump unit 302-1, which is controlled as required via a pulse-width modulated signal (PWM signal). The speed of the pump is varied according to the measured temperatures in the stratified heat storage tank 700 and in the solar collector via a 0-1 0V PWM signal that is sent to the pump by the solar control module. With an increasing temperature difference between the solar collectors and the stratified heat accumulator 700, the speed of the pump and thus the pumped volume flow of the solar medium is increased. This increases the heat transport from the collector to the storage tank. If the temperature difference falls, the speed of the solar pump is also reduced so that the heat transport from the solar collectors is maximized by the increased residence times in the solar collectors and in a smooth tube heat exchanger of the stratified heat accumulator 700. Through this PWM control of the pump reduces stagnation times and maximizes heat transfer. This has a positive effect on the efficiency and the service life of the solar thermal system.

iii: solid/fossil fuel operation

The operation of a solid fuel heating system such as a water-bearing stove is also controlled by the heat pump controller via a temperature difference. If the furnace temperature exceeds the storage tank temperature, the circulating pump of the heating function group for the solid fuel heating system is also activated. An integrated thermostatic switching valve is also used here to raise the return temperature in order to bring the temperature of the furnace circuit up to the level of the storage tank and thus prevent the temperature stratification in the stratified heat storage tank 700 from being destroyed or impaired.

Using the connection points provided according to the present exemplary embodiment for the operating unit B according to the invention, a conventional stratified heat storage device 700 can be connected or combined with the operating unit B according to the following connection diagram: Reference number connection stratified heat accumulator 700 Connection of stratified heat accumulator 700 Reference number connection operating unit 700-A ventilation 700-B Domestic hot water outlet 7 Input connection point for fluid or domestic hot water from the storage unit 700-c Flow drinking water request 4 Output connection points for a solar thermal return to the solar thermal unit 700-D Flow fossil fuel heating 10 Return connection point for a mixed heating circuit 700-E Return drinking water request 6 Flow connection point for hot fluid circulation or hot water circulation 700-F Free 700-I Flow heating circuit 18 Return connection point for the mixed heating circuit to the storage unit 700-G Flow heating requirement 3 Input connection point for a solar thermal flow from the solar thermal unit 700-H Advance solar thermal 24 Return connection point for the solar thermal unit from the storage unit 700L return heating circuit 17 Flow connection point for the mixed heating circuit from the storage unit 700 m Solar thermal return 23 Flow connection point for the solar thermal unit to the storage unit 700-N drinking cold water directly from the house connection 700-O Return heating requirement + return solid fuel heating 20 Return connection point for a heating request to the storage unit 15 Feed connection point for the fossil fuel unit to the storage unit
