Description

Technical Field

[0001] This invention relates to a control unit for controlling the operation of a heat-generating device in an energy system and a method for controlling the operation of a heat-generating device in an energy system. Background Technology

[0002] Energy systems, such as those in cities, industrial areas, or buildings, are characterized by the decentralized production of electricity and heat. Furthermore, energy systems can exchange electricity or heat with external supply networks, such as power grids or heating networks.

[0003] Typically, an energy system has one or more heat-generating devices to provide heat, for example, to cover heat demand outside the energy system. The heat-generating devices can obtain electrical and / or thermal energy through a corresponding power grid, and thereby provide the required heat or thermal power to the energy system.

[0004] Furthermore, the energy system can also connect to a local energy market. Here, energy allocation is achieved through this local energy market, which aggregates and coordinates the buy and sell prices of different forms of energy, particularly electricity and heat. The local energy market is technically implemented through a control platform that controls the energy exchange between energy system components. Such a control platform (energy market, energy market platform, trading platform) is known, for example, from document EP3518369A1.

[0005] The problem with connecting heat-generating equipment to this local energy market is that the equipment operates independently of its load rate, only needing to stay within the maximum load rate of the corresponding capacity equipment. However, the power output of most capacity equipment is related to its load rate. Heat pumps, in particular, strive for high load rates to convert electrical energy into heat as efficiently as possible. However, other secondary technical requirements must also be considered: for example, how to minimize carbon dioxide emissions during operation. Therefore, it may be detrimental to have every device in the energy system operating at the highest possible load rate. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to improve the efficiency of heat generation by means of heat generation equipment in energy systems, especially to improve the carbon dioxide emissions of energy systems.

[0007] This technical problem is solved by a control unit and method for controlling the operation of heat-generating equipment in an energy system. Advantageous design methods and improvements of the invention are provided in this application.

[0008] The control unit according to the invention is used to control the operation of an energy system, particularly a heat-generating device in a building, wherein the energy system is connected to a heating network, and the control device can control the feed (German: Ausspeisen, or output, discharge) and / or feed (German: Einspeisen) of thermal power to and / or into the heating network, wherein the weights... Related to the feed, weight Associated with the feed, and weighted Associated with heat generation through heat-generating equipment, the control unit is characterized in that it is designed to:

[0009] - The maximum heat output of the heat-generating equipment And the heat power required for the energy system The difference between them determines the excess heat power. ;

[0010] - To provide the required thermal power This enables the heat-generating equipment to operate in... Run within the time step; and

[0011] - Excess heat power generated by heat-generating equipment at these times Feed to the heating network.

[0012] The relative concepts of "inside" and "outside" are always used with reference to the energy system. In other words, the terms "inside" and "outside," as well as "within the energy system" or "outside the energy system," are equivalent.

[0013] Here, thermal power and heat are considered equivalent, because thermal power that is constant or changing over a time period always produces the corresponding heat over that time period.

[0014] In principle, time-related quantities are preferably marked with superscript numbers. .

[0015] In discrete cases, a single moment can represent a time range. For example, a time range of 15 minutes is marked with a subscript. And thus, within the scope of this invention, it falls under the time period.

[0016] Furthermore, within the scope of this invention, when a moment or time range satisfies the inequality... In this case, the stated moment or time range is also valid. A sequence of multiple moments can represent a new, continuous time range, which is also valid within the scope of this invention.

[0017] From a structural perspective, especially the IPCC Fifth Assessment Report, the energy system is defined as "all parts relating to the production, conversion, supply and use of energy" (see Annex I, page 1261).

[0018] Energy systems specifically refer to cities, districts, towns, residential areas, campuses, buildings, residences, office buildings, industrial zones, industrial facilities and / or any other definable structures related to energy conversion, energy supply and / or energy use.

[0019] As energy technology equipment, an energy system may include one or more of the following components: generators, combined heat and power plants, especially combined heat and power plants, gas boilers, diesel generators, heat pumps, compression chillers, absorption chillers, pumps, district heating networks, energy transmission pipelines, wind turbines or wind turbines, photovoltaic systems, biomass plants, biogas plants, waste incineration plants, industrial plants, conventional power plants and / or similar equipment.

[0020] The energy system is connected to both an electricity supply network (power grid) and a heat supply network (heating network). The control unit according to the invention enables control of heat flow from the energy system to the heating network or from the heating network to the energy system, and / or heat transfer. In other words, the control unit according to the invention is designed to control heat exchange between the energy system and the heating network, particularly between the energy system and the heating network, and between the energy system and the power grid.

[0021] The heating network is preferably constructed as a long-distance heating network and / or a short-distance heating network.

[0022] Furthermore, at least a portion of the fed-in heat is generated by a heat-generating device. This heat-generating device, in particular, converts electrical energy into heat. In other words, the heat-generating device generates heat that can be supplied from within and / or from the outside. For this purpose, the heat-generating device can absorb heat at a specific temperature level from the heating network, the ground, and / or ambient air to provide heat at a higher temperature level while consuming electrical energy, such as that from the power grid. The heat provided by the heat-generating device can, in principle, be used internally and / or fed back to the heating network, i.e., used externally. Therefore, the control unit according to the invention is designed to control the internal and / or external supply and / or internal and / or external use (feeding to the heating network) of heat from the heat-generating device.

[0023] According to the present invention, weight Related to the feed into the heating network, weight Associated with the feed from the heating network, and weighted This is related to the heat production of the heat-generating equipment. In other words, weights are assigned to the feed, feed, and internal heat production. These weights describe secondary characteristics associated with the feed, feed, and heat production, such as unit CO2 emissions or specific CO2 emissions.

[0024] The control unit may include weights, such as weights in the form of data storage. Alternatively or supplementally, the weights may be provided to the control unit from other units of the energy system. Furthermore, external provision is also provided. The weights preferably have any positive value.

[0025] To illustrate the weights and their technical implications, the weights are generally and exemplaryly, and particularly non-limitingly, designed as units of carbon dioxide emissions. Thus, the weights have units of kg(CO2) per kW (kg(CO2) / kW) or (when related to energy / heat) kg(CO2) per kWh (kg(CO2) / kWh) over a time period. In other words, the internal heat production of the feed-in, feed-out, and heat-generating equipment is associated with units of carbon dioxide emissions.

[0026] The basic idea of ​​this invention is that the required thermal power (internal heat demand) can, in principle, be covered or satisfied by heat-generating equipment and / or by feeds from the heating network. If the required thermal power is completely covered by the heat-generating equipment, the heat-generating equipment can generate more heat without exceeding its load rate, that is, provide excess thermal power. The excess thermal power is fed into the heating network.

[0027] The key understanding of this invention lies in the fact that when the inequality is satisfied... At that time, it is advantageous, for example, in terms of carbon dioxide emissions from the energy system, that the heat-generating equipment operates at full load rate and feeds in excess heat power. In other words, it is advantageous that the heat-generating equipment operates within the effective timeframe or effective period of the invention. Therefore, for those labeled as The control unit checks whether the conditions are met at the specified time or within the specified time range. If the conditions are met, a control signal is sent to the heat-generating equipment through the control unit, thereby enabling the heat-generating equipment to absorb heat at full load.

[0028] If the weight is thermal carbon dioxide emissions, then the items on the left... This corresponds to the total amount of carbon dioxide emissions associated with the required heat power from the external heating network. The term on the right-hand side of the required inequality corresponds to the carbon dioxide emissions associated with the internal coverage of the required heat power (heat production by the heat-generating equipment) and the feeding of excess heat power into the heating network. Since it symbolically flows out of the energy system, the feeding term has a negative sign. Thus, the required inequality, or condition, technically ensures in the case of carbon dioxide emissions: assuming the heat-generating equipment operates at full load (full load rate), if the carbon dioxide balance between internal heat production and the required heat power being better and lower when provided by external coverage from the heating network, then internal heat production is used to cover the required heat power.

[0029] In other words, heat-generating equipment in It operates within a time step to cover the internal heat load. Conversely, it operates within a time step that meets the requirements of... Within a given time step, the required heat power is obtained from an external heating network. Therefore, the heat pump does not operate during this time step.

[0030] In other words, the control unit is designed to control the heat-generating equipment according to the first and second operating modes. The first operating mode is achieved through... Marking. Here, heat is generated by the heat-generating equipment at full load rate, and excess heat is fed into the heating network. The second operating mode is achieved through... The required heat is extracted through the heating network, i.e., fed from or obtained from the heating network. Therefore, the first operating mode is the heat generation mode of the heat-generating equipment, and the second operating mode is the heat extraction mode of the heat-generating equipment. The control unit is designed to determine the corresponding operating mode, or to switch between the generation and extraction modes.

[0031] Advantageously, the two operating modes provided according to the invention allow the heat-generating equipment to operate at full load and thus with the highest possible energy efficiency, while simultaneously minimizing weighted characteristics of the energy system, such as its carbon dioxide emissions. The weights may also be the mass of harmful substances, such as nitrogen dioxide emissions or other greenhouse gases, or represent the availability of renewable energy sources associated with feed-in, feed-out, and / or heat generation. Furthermore, prices, such as carbon dioxide prices, may also be used as corresponding weights.

[0032] In the case of carbon dioxide emissions, this invention can thereby improve the CO2 footprint of the energy system in terms of heat production, and further enable the heat-producing equipment to operate more energy-efficiently. In the case of renewable energy, through the control unit of this invention, the energy system can better respond to fluctuations in renewable energy and can symbolically follow these fluctuations, thereby following the generation of renewable energy.

[0033] In other words, the heat-generating equipment can be operated with the highest possible efficiency without compromising internal (thermal) comfort, and the highest possible load rate of the heat pump is also achieved.

[0034] The method according to the invention is used to control the operation of an energy system, particularly a heat-generating device in a building, wherein the energy system is connected to a heating network, and the feed of heat power into and / or out of the heating network can be controlled by means of a control device, wherein weights Related to the feed, weight Associated with the feed, and weighted Associated with heat generation through heat-generating equipment, characterized in that,

[0035] - The maximum heat output of the heat-generating equipment And the heat power required by the energy system The difference between them determines the excess heat power. ;

[0036] - To provide the required thermal power This enables the heat-generating equipment to operate in... Run within the time step; and

[0037] - Excess heat power generated by the heat-generating equipment (4) at this moment Feed to the heating network.

[0038] One or more functions, features and / or steps of the method according to the present invention and / or the method according to the present invention and / or various design schemes thereof can be implemented with computer assistance.

[0039] The advantages and design of the method according to the present invention are similar to and equivalent to the control unit according to the present invention.

[0040] According to an advantageous design method of the present invention, weight , and These are the values ​​of harmful substances or environmental factors, especially greenhouse gases.

[0041] This allows for the advantageous improvement of energy technology efficiency at full load rate for heat-generating equipment, as well as the efficiency of the energy system in terms of relevant hazardous substance values, such as nitrogen dioxide, or relevant environmental values, such as greenhouse gases, to cover internal heat demand. Consequently, the energy system exhibits synergistic effects in heat generation and reduction of hazardous substance and / or environmental values. Mixed weights can be set, for example, in the form of a product of individual weights. Furthermore, the weights are typically "ratios," i.e., in terms of thermal power (mass per power) or heat (mass per energy). Thus, the weights represent the specific emissions (by mass) of each hazardous substance, environmental value, and / or greenhouse gas.

[0042] In an advantageous improvement of the invention, the weight , and These are relative to carbon dioxide emissions.

[0043] In other words, carbon dioxide emissions are used separately for each weight. This makes the energy system more efficient in terms of heat production—due to the possibility of operating at full load—and its carbon dioxide emissions in a favorable manner.

[0044] According to an advantageous design according to the invention, the heat-generating device is constructed to have a power rating of [missing information]. A heat pump, wherein the control unit is designed to utilize... The maximum electrical power of the heat pump Determine the maximum thermal power.

[0045] In other words, the maximum thermal power of a heat pump is determined by its maximum electrical power, which the heat pump draws from the power grid to generate or provide heat or thermal power. This results in more efficient operation, i.e. At certain times, the heat pump cannot operate at essentially full load, meaning it acquires or consumes its maximum electrical power. Therefore, the heat pump provides its essentially maximum thermal power, wherein the heat pump operates to cover the required thermal power (internal heat demand) within the efficient timeframe described in this invention, and excess thermal power is fed back to the heating network. The power of the heat pump can preferably be controlled by a control unit.

[0046] In an advantageous improvement of the invention, the control unit is designed to receive external temperature via a measurement unit of the energy system. At least one measured value, and thus based on the external temperature Determine the power number .

[0047] Advantageously, this takes into account the temperature-dependent efficiency of the heat pump or the heat supplied by the heat pump. This is because the temperature-dependent power factor is incorporated into the inequality used to determine the effective time. In other words, the effective time for the heat demand of the energy system to be at least partially met internally by the heat pump is determined by inequalities or conditions. Confirmed. In other words, for each label as... The time or time range for checking conditions is determined by the control unit. If the conditions are met, a control signal is sent to the heat pump via the control unit, causing the heat pump to operate at full load. The efficiency of heat delivery is further improved by taking the temperature-dependent power factor of the heat pump into account in the conditions.

[0048] According to an advantageous design of the invention, the control unit is designed to control the feed into the heating network, thereby reducing excess heat power. The inflow or supply fed into the heating network.

[0049] In other words, excess heat power is preferably input into the inflow. Here, this is achieved via a heat exchanger, into which the inflow or return flow of the heating network is introduced to absorb excess heat. The inflow or return flow that raises its temperature at the heat exchanger is then introduced into the inflow. In other words, the return or inflow of the heat exchanger is introduced into the inflow through the heat exchanger. Thus, all excess heat / heat power is directed into the inflow of the heat exchanger. Here, the heat-generating equipment is thermally coupled to the heat exchanger.

[0050] In an advantageous embodiment of the invention, the control unit is designed to control the feed into the heating network, thereby reducing excess heat power. The return flow is fed into the heating network.

[0051] In other words, excess heat power is preferably fed back into the reflux. Here, this is achieved via a heat exchanger, into which the reflux from the heating network is introduced to absorb excess heat. The reflux, whose temperature has increased at the heat exchanger, is then reintroduced into the reflux system. In other words, the reflux from the heat exchanger is introduced into the reflux system through the heat exchanger. Thus, all excess heat / heat power is directed into the reflux of the heat exchanger. Here, the heat-generating equipment is thermally coupled to the heat exchanger.

[0052] According to a preferred embodiment of the invention, the control unit is designed to control the feed into the heating network, thereby feeding in excess heat power. Increase the temperature of the return and / or inflow of the heating network.

[0053] In other words, the inflow and / or return flow of the heating network is introduced into the heat exchanger, thereby raising its temperature by absorbing excess heat power. The heated inflow is then reintroduced into the inflow. If the return flow occurs at the heat exchanger and its temperature is raised by the absorbed excess heat power, then the return flow can preferably be introduced into the inflow or return flow of the heating network. This forms three different preferred feed modes: return-heat absorption-inflow (first feed mode), return-heat absorption-return (second feed mode), and inflow-heat absorption-inflow (third feed mode).

[0054] In other words, the feed into the heating network is preferably carried out according to the first feed mode, wherein the excess heat power generated by the heat generation equipment... The return flow, which is transferred to the heating network and thereby increases its temperature, is introduced into the inflow of the heating network, or according to the second feed mode, wherein the excess heat power generated by the heat-generating equipment is used in this process. The return flow transferred to the heating network, and thereby increasing its temperature, is guided back to the heating network, or according to the third feed mode, wherein the excess heat power generated by the heat-generating equipment is used in this process. The inflow that is transferred to the heating network and thereby increases its temperature is returned to the heating network.

[0055] In an advantageous improvement of the invention, the control unit is designed to control the inflow and / or outflow from the heating network by switching valves.

[0056] In other words, the control unit is designed to switch or adjust the feed modes among the three feed modes via an adjustment valve. According to the first feed mode, excess heat power is used to raise the temperature of the return water, or specifically the reflux water, and then input it into the inflow. According to the second feed mode, excess heat power is used to raise the temperature of the return water, or specifically the reflux water, and then fed back into the return flow. According to the third feed mode, excess heat power is used to raise the temperature of the inflow water, or specifically the inlet water, and then fed back into the inflow.

[0057] Furthermore, the control unit is preferably designed to control the corresponding mass flow rate of the heat transfer medium in the heating network. The heat transfer medium is, for example, water.

[0058] According to an advantageous design of the invention, the control unit has a communication module that enables data exchange with a central control device relative to multiple energy systems, wherein the central control device controls energy exchange between the energy systems, and the communication module is designed to receive weights from the central control device. , and .

[0059] In other words, the preferred option is weighting. , and Provided through a central control device relative to multiple energy systems.

[0060] Thus, the energy system is coordinated in terms of its efficiency through a central control device. This improves the efficiency of heat delivery, particularly overall CO2 emissions. The central control device symbolically assigns weights and transmits them to the energy systems or their respective control units, enabling each energy system to operate one or more heat-generating devices within its respective effective timeframe. The central control device, for the energy system in question, calculates or determines the weights based on data / information pre-transmitted to the energy system. Optimization methods can be used to calculate, for example, minimizing the total CO2 emissions of all participating energy systems. This further reduces or improves the CO2 footprint of the energy system.

[0061] Furthermore, the energy management system of the energy system may include control units and thus communication modules. Since the central control equipment sets weights and thereby substantially confirms when the corresponding heat-generating equipment operates, the central control equipment (through the control units) controls heat generation and heat input. Thus, the central energy market platform controls valves and / or mass flow rates, at least indirectly, in terms of heat transfer from excess heat power to the heating network. In addition, the central control equipment can control the consumption and / or generation of electrical energy in the corresponding energy system. Therefore, the central control equipment is constructed as a local energy market platform for heat, and thus, in an advantageous design, as a local energy market platform for both heat and electricity. In other words, the central control equipment technically forms a local energy market for heat and / or electricity. Furthermore, quotations regarding heat output and / or heat input can be transmitted to the central control equipment via the communication module. Attached Figure Description

[0062] Other advantages, features and details of the present invention will become apparent from the embodiments described below and with the aid of the accompanying drawings.

[0063] The only accompanying drawing schematically illustrates the overall system, which includes a control unit designed according to the present invention.

[0064] Elements of the same kind, equivalent or having the same function may be labeled with the same reference numerals in the accompanying drawings. Detailed Implementation

[0065] The accompanying drawings schematically illustrate the primary side 20 and the secondary side 40 with respect to the heating network 2. Here, the primary side 20 includes the heating network 2 and a coupling unit 3. The coupling unit 3 couples the heating network 2 to the secondary side 40 in terms of the heat exchanger. The secondary side 40 includes, or represents, a side of one or more energy systems. Here, the energy systems include a control unit 42 and a heat pump 4 according to the design according to the present invention.

[0066] A heat exchanger 5 is provided to couple the heat exchange network 2 with the heat technology equipment on the secondary side 40, particularly with the heat pump 4. Important for the transferred heat power are the temperature difference between the heat source and the heat exchanger 5's internal fins or heat absorber, as well as the mass flow rate of the transfer medium. The transfer medium is typically water. The temperature of the heat source (here, the pump 4 on the secondary side 40) can be controlled or adjusted via a control unit 42. The mass flow rate can, in principle, be regulated by a valve that controls the control unit 42. Here, depending on the operating mode, the temperature of the heat source is either the temperature of the heat exchange network 2 or the temperature of the secondary side of the energy system after its own consumption.

[0067] The heating network 2 has an inflow 21 and a return 22. Through the connection of coupling device 3 and heat exchanger 5, the inflow 21 and / or return 22 of the heating network 2 are thermally coupled to the heat pump 4, that is, thermally coupled to the heat-generating equipment of the energy system. For this purpose, the coupling device 3 includes multiple valves 31 and a pump 32. In the accompanying drawings, the fluid lines of the valves are shown as the internal operation of the coupling device 3. The valve lines enable three feed modes of heat generated by the heat pump 4 to the heating network 2.

[0068] According to the first feed mode, the control unit 42 controls multiple valves 31 to guide the return flow 22 of the heating network 2 through the heat exchanger 5 and back to the inflow 21 of the heating network 2. In the second feed mode, the control unit 42 controls the valves 31 to guide the return flow 22 of the heating network 2 through the heat exchanger 5 and back to the return flow 22. In other words, the circuit through valves 31 forms a bypass for the return flow 22, which passes through the heat exchanger 5. In the third feed mode, the control unit 42 controls the valves 31 to guide the inflow 21 of the heating network 2 through the heat exchanger 5 and back to the inflow 21. In other words, the circuit through valves 31 forms a bypass for the inflow 21, which passes through the heat exchanger 5. The control unit 42 can switch or adjust the feed mode between the feed modes by controlling the valves 31.

[0069] In addition, the coupling device 3 also includes a heat exchanger 5.

[0070] The secondary side 40, or energy system, includes the secondary heating network already mentioned above. The secondary heating network, shown only schematically in the accompanying drawings, is also used for heat distribution within the energy system.

[0071] Control unit 42 is also arranged on the secondary side 40. Here, the energy system includes control unit 42. Control unit 42 is designed to exchange data / information, particularly control signals, control values, and / or other data or information, with coupled device 3, heat pump 4, energy management system 43 of the energy system, and central control device 44 of the various energy systems. Central control device 44 constitutes the local energy market. In other words, control unit 42 enables communication with coupled device 3, heat pump 4, energy management system 43, and local energy market 44. This communication capability is indicated in the figures by the dashed arrow starting from control unit 42.

[0072] The control unit 42 is thus designed to control the operation of valve 31 and / or pump 42 of the coupled device 3, as well as heat pump 4. This control can be performed using control signals, which the control unit generates based on data received from the energy management system 43 of the local energy market 44 and / or the energy system, and transmits to heat pump 4.

[0073] According to one design of the present invention, based on the first step of the method, excess heat power The maximum heat power of the heat pump 4 is controlled by the control unit 42. And the heat power required by the energy system The difference between the two is determined. For this purpose, the required thermal power is provided to the control unit 42, for example, via the energy management system 43. The control unit 42 can calculate the excess thermal power from the difference between the maximum permissible thermal power and the thermal power required within the energy system.

[0074] In the second step of the method, the heat pump provides the required thermal power. And in It operates within a time step. In other words, the control unit checks whether the conditions are met. When this condition is met, heat pump 4 operates. Otherwise, the required heat power is extracted or obtained from heating network 2. For this purpose, control unit 42 accordingly controls heat pump 4, or coupling device 3, especially valve 31 and / or pump 32.

[0075] Furthermore, in the third step of the method, the excess heat power generated by the heat pump 4 at that moment... It is fed out to the heating network, that is, transferred to heating network 2.

[0076] In other words, when the above conditions are met, heat pump 4 can operate at full load, where excess heat power not needed in the energy system is fed back to heat network 2 for other uses, such as by other energy systems. Thus, heat pump 4 operates at full load for a longer period, thereby enabling the heat pump to have a higher power output and thus higher efficiency, at least within the stated effective time period.

[0077] The effective time or effective time range is determined by conditions. It is confirmed that the condition includes multiple weights or weighting coefficients. , and The weighting coefficients technically ensure that not only the energy efficiency of heat pump 4, i.e., the heat generated from electricity, is important, but also other important technical characteristics, such as carbon dioxide emissions, are taken into account. Thus, while achieving low carbon dioxide emissions from the energy system, heat pump 4 operates at full load (energy efficiency) through control unit 42. In other words, it is clearly more advantageous for the energy system to generate heat itself through heat pump 4 and feed the excess heat into the system during the effective time period or effective time range than to extract heat from heating network 2. During times or time ranges where the conditions are not met, it is clearly more advantageous for the energy system to obtain heat from heating network 2 to cover internal heat demand. Therefore, control unit 42 dynamically controls the heat source for heat demand—heat network 2 or heat pump 4—according to the weights. Thus, the weighting ensures the technical objective of simultaneously achieving the lowest possible carbon dioxide emissions and the highest possible energy efficiency for heat coverage.

[0078] Weight , and The energy can be supplied and / or transmitted to the control unit 42 via the central control device 44 and / or energy management system 43. This enables dynamic adjustments, for example, regarding carbon dioxide emissions, as carbon dioxide emissions associated with, for example, extraction (feedback) from the heating network 2 may vary over time. Furthermore, carbon dioxide emissions associated with heat production may also vary over time. In other words, weighting... , and It is time-related, and therefore the weight is transmitted to the control unit 42 at regular time intervals, such as in advance every 15 minutes during the day, via the central control device 44 and / or the energy management system.

[0079] Thus, the design shown in this invention achieves high-efficiency heat generation through the heat pump 4 while simultaneously reducing carbon dioxide emissions from the energy system, and further combines these two savings synergistically.

[0080] Although the details of the invention have been illustrated and described in detail through preferred embodiments, the invention is not limited to the disclosed examples, and those skilled in the art can derive other different variations therefrom, as long as they do not depart from the scope of protection of the invention.
