Description

Multifunctional Energy Module, Multifunctional Energy System and Light Component

Technical Field

The present technical solution falls within power engineering field focusing on effective utilization and management of electric and thermal energy. The present technical solution relates to a multifunctional energy module, a multifunctional energy system and a light component for the multifunctional energy module. It concerns mainly power light sources producing waste heat removed by a fluid.

One of the utilizations of the multifunctional energy module uses an ability to actively remove and transport the generated waste heat from light sources, which are its essential components, and thus the technical solution falls also within the narrower field of technical equipment of buildings and lighting technology.

Background Art

In the state of the art are generally known such technological devices (systems) that individually provide suitable conditions within a space for human stay or plant growing, i.e. light comfort, heat comfort, and air exchange. Since each of these represents standalone operating device or system, to equip the space with such devices requires an individual investment in their acquisition, installation and subsequently also financial expenses for service and maintenance thereof. No technological device that would reliably and fully fulfil function of multiple such devices (end elements of the system) and at the same time would provide a high energy efficiency of such object (building) has been known in the state of the art so far.

Currently, the most widely used light source in a lighting technology is a luminescent diode (LED; light-emitting diode). The reason for its strong position in a market is high durability and high luminous efficiency. The used LED light sources in electric luminaires utilize only approximately 30 % of consumed electric energy for conversion of electromagnetic radiation in the visible spectrum. Remaining 70 % is a form of the generated waste heat that represents energy losses in form of the heat, which unfavourably influence the actual lifetime of a semiconductor in LED light sources as well as values of its specific capacity.

Often these energy losses are also sources of energy that deteriorates actual thermal comfort for humans in the space during warm season. For the LED light source to be sustainably effective light source in lighting technology it is necessary to maintain its high specific capacity and durability at the same time. In practice it means that it is necessary to provide sufficient cooling of the LED light source. In the state of lighting technology, this is solved by passive but also active cooling with a ventilator directly on/inside of the luminaire, which makes the lighting system more expansive and this negatively influences return on investments. This represents the cooling of the luminaires that indeed provides suitable operating parameters for the light source, but unfavourably contributes to heat comfort during warm season, when, even if the cooling system is installed in the space, its cooling performance must be overdesigned by this thermal contribution. However, the positive effect during winter season is only minimal or negligible, as higher installed heights of the lightening system, especially in industry, are mainly concerned.

Utilization of such LED luminaires is limited in spaces with higher ambient temperature, where the standard way of cooling is insufficient. It has high impact on aging speed of the LED light source (decrease of luminous flux over time), which is already reflected in a lighting-technical design (by so called maintenance factor). The faster the aging of the light source is, the greater the need for luminous overdesign of the space (installed power of the lighting system) is, in order to make the desired projected intensity level of the lighting maintainable over time.

In the state of art are already generally known such technical solutions that by means of a circulating fluid actively remove generated waste heat from light sources, which is then effectively utilized. Their positive contribution for humans is clearly given, but only in terms of removal, transfer and utilization of thus obtained generated waste heat from light sources. The reason why such technical solutions are rarely used in practice is high economical return on investment, i.e. low energetic and financial saving in high investment.

The patent document PP 50024-2014 discloses a LED luminaire with conversion of waste heat to electric energy, consisting of the system of LED light sources and a cooler, wherein a semiconductor thermoelectric generator with voltage output is heat-conductively inserted between a supporting baseplate with installed system of LED chips of the LED light source and the cooler. The solution mentioned in this patent document fulfils only the function of conversion of waste heat to electric energy.

Patent documents CN203571485 and CN101936495 relate to cooling of LED luminaires and they use waste heat for being converted to electric energy. The patent document CN103471061 removes heat from the LED luminaires and uses it for heating air in a plant factory. However, neither of solutions mentioned in these patent documents fulfils the function of heat recuperation, air cooling, air exchange, air heating, heat production in form of warm water and air exchange at the same time.

The LED light source has been used in lighting technology for a relatively short time to show in well-founded measure its future lack of free accessibility of a spare part, which is the LED light source itself with specific parameters (shape, proportions, power, way of attachment and electrical connection). The reason for this threatening lack is the individual form of use by producers in different designs of luminaires, which, in the time of reaching the end of life, do not have to be produced anymore.

In the state of art is generally known an overhead cooling system that is considered to be one of the most comfortable and effective cooling methods because of its principled way of cooling. However, this system is rarely used in industry, because of high acquisition cost of the overhead cooling system that would be used only during a relatively short period of the year.

Nature of Invention

The aim of the present technical solution is to provide such waste heat utilizing system that would remove the abovementioned deficiencies.

The present technical solution provides sufficient artificial lighting in a space for humans, plants, or animals, while supplying heat in the form of the captured generated waste heat from a light source/sources by means of circulating working fluid that passes through a module and that at the same time serves for transfer and distribution of heat/cold during heating/cooling of such space. The module for humans, animals, or plants also provides air exchange, optionally also distribution of fresh air from ducts of an existing or planned system that is connected with exterior by its fixed ducts. The module decreases or increases temperature of ambient environment by means of distribution of air being warmer or colder than is the temperature of ambient environment and thus provides appropriate thermal comfort for humans, animals, or plants in such space, i.e. space heating and cooling. During distribution of warmer air (heating), the module intakes a radiant heat and distributes it back perpendicularly downwards to the space of human stay (reuse of the radiant heat).

The abovementioned deficiencies from the state of art are substantially removed by a multifunctional energy module. An installed group of such modules in space represents the system of modules that has following spectrum of use (functions): 1. It provides artificial lighting with active cooling of light sources also in spaces with higher temperature of ambient environment.

2. It provides collection, transfer, and use of the generated waste heat from the light sources that can be used to prepare hot service water, production heat, or heating heat.

3. It provides reduction of ambient temperature in the space during warm season, i.e. distribution of cold into the space by means of natural radiation of cold and by means of artificial airflow from top to bottom.

4. During the season of the year with low heating heat demand, it is able to distribute the generated waste heat from the switched-on light sources downwards directly to the space and thus to create adequate thermal comfort, using only this generated waste heat from the light sources, i.e. without necessity to activate a main heat source.

5. During wintertime it is able to provide distribution of heating heat by means of artificial airflow from top to bottom, wherein during this operation, the reuse of the radiant heat back to the space occurs, whereby it still provides also sufficient cooling of the light source.

6. It provides exchange and filtration (cleaning) of the air present in the space, or also distribution of the fresh air conveyed from exterior.

The multifunctional energy module designed mainly for utilization of waste heat generated by light sources and for distribution of heat/cold into a space comprises a core designed for passage of a heat- transfer fluid that is adapted for attachment of the light source, a diffuser, a heat exchanger, a control member at the input, a control member at the output, an inlet and outlet opening or an inlet and an outlet pipe adapted for connection of a system pipe, an air-flow directing element, and a ventilator. The inlet opening or the inlet pipe is connected to the control member at the input, the control member at the input is further connected to the core and the core is further connected to the control member at the output, which is connected to the output opening or the output pipe. The core is hermetically sealed by the diffuser in the part adapted for attachment of the light source. Above the core is located the heat exchanger that is connected via a pipe with the control member at the input and with the control member at the output. Above the heat exchanger, the airflow directing element is located, and above the element, the ventilator is located. The heat exchanger has sufficient heat exchange surface. Preferably, the air-flow directing element is a thermal insulation. The air-flow directing element has the shape adjusted to direct the flowing air from the ventilator to the heat exchange surface of the heat exchanger. The multifunctional energy module further contains a circulator pump for providing circulation of the fluid which can be arranged in any part of the module designed for circulation of the heat-transfer fluid.

The core of the module is made of solid anticorrosive material so that it allows passage of the heat-transfer fluid through its interior. The shape of the core of the module forms on the bottom side a space for firm attachment of the light source. This space is then hermetically sealed in a cover made of light-permeable material. The light source is by its shape and dimensions adjusted for being attached to the core of the multifunctional energy module. This coved is the diffuser. The diffuser is made of transparent or diffuse material for adequate emission of the light from the light source into surrounding space. Elements for collection of formed condensate and subsequently its removal into a discharge pipe can be parts of the diffuser. Condensate drainage can represented by individual bodies or alternatively it is provided by shape of the core itself.

In this space, an individual body can be arranged and mounted, the part of which is already the light source, providing sufficient IP cover for penetration of moisture, output of the emitted light into surrounding space and sufficient contact heat exchange surface between the core and the light source in this body.

The control member at the input comprises pipes and at least two electrically controlled vents. It is possible to provide a desired circulation cycle by closing and opening them and thus provide operation of a chosen operating mode.

The control member at the output comprises pipes and at least two electrically controlled vents. It is possible to provide a desired open circulation cycle by closing and opening them and thus provide operation of a chosen operating mode.

The inlet pipe and the outlet pipe providing inlet and outlet of the heat-transfer fluid under certain pressure during operating mode for the module, when it is necessary, is firmly and in exchangeable way connected to the system pipe.

It is preferred if there are at least two or more ventilators with an electromotor and they are interconnected via a rotary axis and jointly arranged in the cover that has on the end sides intake openings with air filters to capture impurities. The intake air is blown off to the heat exchange surface of the heat exchanger through a longitudinal opening in the cover.

The thermal insulation with appropriate heat-insulating properties is mounted in close proximity of the heat exchanger from above in such manner that the shape of the heat exchanger directs the produced flowing air towards the heat exchange surface of the heat exchanger and downwards to the surrounding space under the module. The multifunctional energy module can also comprise assembly elements.

By installing the group of multifunctional energy modules in space (system of modules), it is possible to assemble such multifunctional energy system that uses a thermal potential of the circulated heat-transfer fluid within it all year-long and all year-long is multi-purposely used in the space. This fluid serves for collection and transfer of the generated waste heat and for distribution of cold/heat into the surrounding space. The system of modules represents single and for humans all year-long usable technological system that simultaneously and mutually independently positively contributes to their light comfort, heat comfort and air exchange, wherein during a heating mode it is able to utilize part of the radiant heat and distribute it back do the space. Such energy system contributes to reduction of energy demand factor and CO2 emissions in buildings and thus significantly contributes to better evaluation in energy performance certificates and increases energy efficiency.

Inevitable components of the functional module system are at least two multifunctional energy modules according to the present technical solution. The multifunctional energy system further comprises a system pipe for distribution of the heat-transfer fluid, energy devices and a control system, wherein at least two multifunctional energy modules are interconnected via a system pipe and the control system contains evaluating, measuring, and controlling devices. The evaluating device is a hardware equipped with a software for collection of data from measuring devices, their evaluation and setting of a working mode of the modules and of the energy device to achieve required level of illumination, ambient temperature and temperature of the circulating fluid. The evaluating device evaluates actions necessary to achieve required level of illumination, ambient temperature and temperature of the circulating fluid. These actions concern either directly the multifunctional energy system, such as alteration of speed of the ventilator, alteration of the light source efficiency, opening/closing of electric vents in the control member at input/output, or they are actions of controlling elements in the energy devices, the assembly of which can be individual in each case. The energy device can be, for example, a gas boiler, a heat pump, a combination thereof etc.

The aim of the control system is to ensure that the output of such energy devices is such to obtain desired temperatures.

The measuring devices can be, for example, a thermometer for measuring the temperature of the circulating fluid in the system, a thermometer for measuring the temperature of the ambient environment, a flowmeter for measuring the flow of the circulating fluid in the system, a barometer for measuring the pressure of the circulating fluid in the system, a calorimeter for measuring the energy transfer by the fluid in the system, and a luxmeter for measuring the intensity of illumination.

The system pipe has good thermo-insulating properties and is made of sufficiently firm material. The heat-transfer fluid is under certain pressure, at a certain temperature and at a certain flow rate circulated through the system pipe among which individual modules are attached, through which also passes this circulating fluid that serves for collection and transfer of the generated waste heat and for distribution of cold/heat into the surrounding space.

The energy device or the system of devices work appropriately with thermal and electric energy. During normal operation it provides circulation of the heat-transfer fluid, necessary pressure of the circulating heat-transfer fluid, necessary purity (filtration) and elimination of scale formation, necessary and controllable flow of the circulating heat-transfer fluid, necessary volume of the circulating heat-transfer fluid, necessary temperature of the circulating heat- transfer fluid at output from the energy device, either by means of supplying or removing the heat to/from this fluid during its passage.

The system of modules enables a maximum compatibility with all energy devices that work in a suitable way with electric or thermal energy. Such energy devices can be, for example, a photovoltaic (cell), a solar collector, an earth collector, a wind turbine, a battery system, a heat pump, a heat exchanger, a reservoir of circulating fluid, a boiler (gas, electric, for solid fuel), an atmospheric cooler, electric resistance spirals or combinations thereof.

The multifunctional energy module can be partially (only one of two intake openings) or fully connected to ducts of existing or planned air-conditioning equipment and thus it is possible to alter the temperature of the surrounding space by altering the temperature of fresh air distributed from exterior.

The multifunctional energy module provides slower aging of the light source due to active cooling, and thereby its durability is achieved or even extended. Because of that the multifunctional energy system allows to design the lighting system with really needed installed power input and minimal power margin.

The multifunctional energy module reliably fulfils following functions of individual technical devices:

1. function of lighting element,

2. function of end device for cold delivery,

3. function of end device for heat delivery, 4. function of body for distribution, cleaning, and alternation of temperature of air (ambient, fresh, or combined mixture thereof),

5. function of element for reuse of the radiant heat during heating.

The energy multifunctional module represents such device that can operate also in a mode with internally closed circulation cycle of the heat-transfer fluid and thus remove the generated waste heat from the switched-on light sources and subsequently distribute it directly into the space in form of heated air.

Overview of Figures

Respective embodiments of the technical solution depicted on following figures are introduced only for illustration of the solution and not as restrictions to particular realizations of the technical solution. The multifunctional energy module is constructed in a way and from materials known to skilled persons in the art.

Fig. 1 shows cross-sections of the multifunctional energy module with two different shapes of the module core, on which is dependant the number of applicable heat exchangers and thus also the size of overall heat exchange surface of the module with the surrounding space. Fig. 1 also shows an alternative of the most preferred manner of construction of the inner space of the core with longitudinal protrusions for ideal removal of the generated waste heat from the light source into the heat-transfer fluid.

Fig. 2 shows one of the possible technical embodiments of the multifunctional energy module and view of it from three different perspectives.

Fig. 3 shows structural layout of the multifunctional energy module into individual components.

Fig. 4 shows schematically the multifunctional energy module and there is also marked an interface between the control member at the input and the control member at the output.

Fig. 5 shows the open circulating cycle inside of the module during such operating mode of the module when the space is heated only by the generated waste heat from the light sources in the module and when it is not necessary to circulate the heat-transfer fluid in the system pipe.

Fig. 6 shows the open circulating cycle inside of the module during heating or cooling operating mode. Such circulating cycle also ensures that the heat-transfer fluid after transmission of heat subsequently circulates through the core to provide also sufficient cooling of the light source. Fig. 7 shows the circulating cycle inside of the module during such operation when the circulating heat-transfer fluid passes only through the core of the module, therefore only removal and transmission of the generated waste heat from the light source occurs.

Fig. 8 shows two possible ways of interconnection of the multifunctional energy module with ducts for air-conditioning technology. At the same time, this figure shows how, in case of at least one unconnected intake opening, the module can capture a part of the radiant heat and distribute is back to the space during heating season.

Examples of Embodiments of the Invention

Example 1

Structural embodiment of the multifunctional energy module represents such device that can be connected by means of the inlet pipe 2 and the outlet pipe 3 to a system pipe 21. The inlet pipe 2 is connected to the control member 8 at the input, the parts of which are necessary pipes, two electromagnetic vents 19, and the small circulator pump 1_8. Subsequently, the control member 8 at the input is connected to the metal core I of the module, the shape of which forms, on the bottom side, the space alongside the whole core J_, where the light source is attached in exchangeable way, which is according to example in Fig. 2 in form of simple LED strips 7 glued on a copper plate 6. This space is subsequently hermetically sealed by the diffuser 4 with suitable circumferential seal, which allows to ensure safe and hygienic condensate drainage 5 by edges of the diffuser 4. The circulating heat-transfer fluid is water that is under certain pressure forced into the inlet pipe 2 and passes through the open direction of the module according to chosen operating mode of the module. During passage through the core1, only the metal wall of the core I and the copper plate 6 is between it and the LED strips 7, and therefore, in case that LED strips 7 are switched on, the water is gradually heated to a temperature higher than it had when entering the module. In this way, the water removes the generated waste heat from the switched-on LED strips 7. On leaving the module, it passes to the system pipe 21 though the outlet pipe 3, which is connected to the control member 9 at the output, the parts of which are necessary pipes and the two electromagnetic vents 19. On upper parts of the module, one or more heat exchangers 7 is/are mounted that are connected by their pipes to the control member 8 at the input and to the control member 9 at the output. The area of the ribbed lamellas represents the heat exchange surface of the module with the surrounding space. In the close proximity, the thermal insulation 12 having appropriate heat-insulating properties is firmly attached from above. Its shape is such as to ideally direct a flowing air from the ventilators 13 to the heat exchange surface. These ventilators 13 are interconnected by the rotary axis 16, together with the electromotor 14, that is a source of their rotary motion, during which they intake the ambient air in horizontal direction through the air filters 15 and blow it off in vertical direction through a longitudinal opening in the cover 1_1_, directly to the heat exchange surface. Power supply for the LED strips 7 is provided by an electronic series resistance arranged in safe distance from the module and having sufficient IP coved against moisture. The multifunctional energy module is firmly mounted in operating position of the space by means of mounting rods 10.

Example 2

Operating mode of the multifunctional energy module according to schematic arrangement in Fig. 5 represents the operating mode of heating using the waste heat only from the light sources. Capability of the module to operate in this mode is achieved by suitable combination of open or closed states of the electromagnetic vents 19 inside the control member 8 at the input and inside the control member 9 at the output, depicted in Fig. 5. The heat- transfer fluid is water that, in this example of the operating mode, is not circulating through the system pipe 21, but only inside the module itself, namely by means of activated running of the circulator pump j_8 inside the control member 8 at the input. In this manner, when LED strips 7 are switched on, the water extracts the waste heat generated by them, heats itself to higher temperature and after that is circulated by the circulator pump 1_8 into the heat exchangers 17. The activated electromotor 14 rotates ventilators 13 that intake the ambient air in horizontal direction and blow it off to the heat exchange surface of the heat exchangers 17. The flowing air is heated there to higher temperature, the water in the heat exchangers 17 is gradually cooled during its passage and subsequently is recirculated by the circulator pump 1_8 to the core j_. The whole circulating cycle is constantly repeated during this operation. The module thus distributes the generated waste heat from the switched-on LED strips 7 directly to the surrounding space beneath it in form of flowing air with temperature higher than is the temperature of the intake ambient air. In this case, the operating mode represents such operating mode of the multifunctional energy module in which the space needs to be heated with lower heat efficiency and thus the generated waste heat from the light sources is sufficient to achieve required heat comfort.

Example 3

Operating mode of the multifunctional energy module according to schematic arrangement in Fig. 6 represents the operating mode of cooling of the surrounding space. Capability of the module to operate in this mode is achieved by suitable combination of open or closed states of electromagnetic vents 19 inside the control member 8 at the input and inside the control member 9 at the output, depicted in Fig. 6. The heat- transfer fluid is water that, in this example of the operating mode, circulates through the system pipe 21, and enters the module with the temperature lower than is the temperature of the surrounding space. Set states of the electromagnetic vents 19 inside the control member 8 at the input ensure that immediately after entering the module, the water enters the heat exchangers 17 by one pipe thereof, wherein the set conditions of the electromagnetic vents 19 inside the control member 9 at the output ensure that this water returns via the heat exchangers 17, through the second pipe thereof. The air having ambient temperature is flown by ventilators J_3 to the heat exchange surface of the heat exchangers 7, and therefore its temperature decreases and at the same time the temperature of the circulating water in the heat exchangers 17 increases, the water is recirculated to the control member 8 at the input and subsequently to the core 1 of the module, where, in case that the LED strips 7 are switched on, it removes the generates waste heat therefrom and heats itself to the higher temperature. After that it circulates to the control member 9 at the output and comes out from the module into the system pipe 21. Circulation of the water is supported by switched-on status of the circulator pump IS inside the control member 8 at the input. During this operating mode, a condensate can be formed on the heat exchange surface and collected by means of condensate drainage 5 and through their openings led to the respective discharge pipe.

Example 4

Identical setting of the electromagnetic vents 19 inside the control member 8 at the input and inside the control member 9 at the output, as disclosed in Example 3 and depicted in Fig. 6, represents also the operating mode for hot-air heating of the space by the module. Water with temperature higher than is the temperature of the surrounding space circulates from the system pipe 21 to the heat exchangers 7 through the control member 8 at the input. By means of the heat exchange surface, the water delivers its heat to the flowing air from the ventilators J_3 and subsequently circulates to the core1 with temperature already lower than it had when entering the module. When the LED strips 7 are switched on, the water removes the generated waste heat therefrom during its passage through the core I , heats itself to higher temperature and comes out from the module back to the system pipe 21 through the control member 9 at the output. Under influence of thermal gravity, the heating heat radiates in space again upwards, where the part thereof is captured by the module and reused for heating of the space due to horizontal intake of the air by the ventilators 13. In this way, the multifunctional energy module allows heating while using the generated waste heat from the light sources and reusing the radiant heat in the space. Circulation of water through the module is supported by switched-on state of the circulator pump j_8 inside the control member 8 at the input.

Example 5

Operating mode of the multifunctional energy module according to schematic arrangement in Fig. 7 represents the operating mode of thermal gain, which occurs in case when there is no need to make a change of the ambient temperature, but it is necessary ensure a light comfort, heat contribution, or possibly also air flow. The capability of the module to operate in this mode is achieved by suitable combination of open or closed states of the electromagnetic vents 19 inside the control member 8 at the input and inside the control member 9 at the output, depicted in Fig. 7. The heat-transfer fluid is water that, in this example of operating mode, is circulated from the system pipe 21 directly to the core J_, where it is heated to the temperature higher than it had when entering the module, and subsequently comes out from the module back to the system pipe 21. The heat thus obtained is then used for preparation of hot service water.

Example 6

In the Fig. 8 are depicted two possible ways when the multifunctional energy module during its operation can work also with fresh air supplied from exterior by means of simple connection with an air-conditioning pipe 22, and without any restrictions of its functions. The air-conditioning pipes 22 are connected to one or both end sides of the cover 11, through which the air is taken in in horizontal direction. In case that only one end opening of the cover 11 is connected thereto, the multifunctional energy module can distribute fresh air and at the same time provide flow of the air present in the space and thus also reuse of the radiant heat during heating operating mode.

Example 7

A preferable embodiment of the multifunctional energy system according to this technical solution comprises at least two multifunctional energy modules depicted in Fig. 9. The inlet pipes 2 of these multifunctional energy modules are interconnected by the compact part of the system pipe 21 that comes out from the energy device 20 or the system of the energy devices and through which the circulating fluid having higher temperature than the temperature of the surrounding space is supplied into the multifunctional energy system during heating operating mode, and the circulating fluid having lower temperature than the temperature of the surrounding space is supplied during cooling operating mode. The outlet pipes 3 of these multifunctional energy modules are interconnected via the compact part of the system pipe 21 and provide transfer of the circulating fluid back into the energy device 20 after carrying out the necessary process of specific operating mode of the multifunctional energy system, i.e. delivery of heat/cold and possibly also collecting and transfer of the generated waste heat.

Example 8

A light component according to this technical solution is designated as spare component for the multifunctional energy module, the inseparable part of which is the light source having sufficient contact heat exchange surface with the core I of the module for removal of its generated waste heat via the contact area with the surface of the core I into the circulating fluid of the system. The light component consists mainly of a material that transmits light, which is emitted by the light source to the space beneath the module. At the same time this material provides a sufficient IP cover against moisture penetration for that light source. Construction of the light component allows to attach it firmly in exchangeable way in the core I of the module and its shape ensures collection and removal of the condensate generated on surface of the core I and on surface of the heat exchanger 7 into the discharge pipe.
