Abstract

Heat recovery system involves a series of pipies mounted in a panel on the roof to give efficient absorption of solar radiation. The heat so picked up is then exchanged with a domestic water supply. An additional amt. of heat is then provided by abstracting heat from the ambient air using a heat pump, this heat also being transferred to the hot water storage tank. The sec. heat pump circuit uses a transfer medium which can be heated by the solar energy and the ambient air. A refrigerant is used for the heat pump circuit and a brine or similar for the prim. circuit. The ambient air is blown over the surface of heat transfer tubing. Used on domestic hot water systems and allows environmental heat to be used for water heating.

Description

Mr. Peter Frieß

In Mühlwiesen 5 7104 Obersulm-Sülzbach Mr. Jörgen Mattes lirschstrasse 3 7066 Baltmannsweiler Process and device for generating heat energy summary A method and a device for generating heat energy are proposed, which serve the previously known systems, for example the global solar radiation take advantage of improving their efficiency and such thermal energy recovery systems designed so that, especially in the cold season, the coverage of the Thermal energy is essentially possible without the use of fossil fuels. For this purpose, in addition to that of a suitable energy transport medium through which isoil bodies that are exposed to global solar radiation, a Heat pump extracting heat from the surrounding air in combination with the first energy generation system used, whereby both energy generation systems (solar global radiation and heat generation from the outside air by means of an air heat pump) work on the same heat storage tank.

As transport elements exposed to the external impact area finned tubes are used for the working medium, which in a preferred embodiment are in the form of integral aluminum tubes. Both types of tubes, namely the evaporator coil for the air heat pump and that of the solar global radiation under a transparent one Fin tubes exposed to the cover are in a unit that can be assembled together arranged, the housing compartment containing the evaporator coil in addition has a blower / fan and an exhaust louvre.

PRIOR ART The invention is based on a method and a Device for generating heat energy according to the genre of the main claim. It is already known to gain thermal energy by that preferably Heat collectors can be placed on house roofs, from the solar radiation are heated and are designed as a hollow body so that they are inside can transport a working medium. It is common as a carrier for the heat transport medium when generating heat from global solar radiation, flat plates, for example to use made of aluminum, which form tubular cavities and from which to be heated Medium flowed through. The circuit boards have an insulating layer on the back surrounded and against the acting radiation by as much as possible Radiation spectrum permeable transparent cover covered so that at corresponding long-term exposure to global solar radiation is considerable Temperatures can develop.

Unfortunately, such heat recovery systems are at their peak Range of services when this is not absolutely necessary, namely in summer, while in winter the necessary heat energy for hot water, heating, swimming pool or the like

generated by additional heating, preferably based on fossil fuels must become.

It is already known and tried, based on the heat pump principle extract heat from the ambient air; here there is the possibility of usable Useful heat can also be obtained at outside temperatures of -5 ° and below lie. The heat pump principle is based on alternating condensation and evaporation a suitable working medium, Frigen preferably being used, which can be used in appropriate coordination with certain temperature ranges can.

Advantages of the Invention The method according to the invention and the method according to the invention Device with the characterizing features of the main claim or the first, on the device related claim has compared to the conventional energy generation systems the advantage that the area of application is considerably extended even in the cold season and additional heating based on fossil fuels is practically no longer available required are. However, it is particularly advantageous that the cost of the inventive combined plant can be significantly reduced; Installation and plant work arise only once. Another advantage is that the two Areas of both energy generation systems exposed to external influences, namely the transport arrangements for the liquid working medium with regard to global solar radiation and the evaporator tubes of the heat pump, arranged in a common housing are, which can already be pre-assembled at the production side.

It is also advantageous that for the transport of the working medium Finned tubes, preferably made of aluminum, are used, which are particularly large Have heat absorption capacity and not just flat in one plane take over the low-noise effect of the Solar-Glohal-Radiation.

The measures listed in the subclaims are advantageous Further developments and improvements of the invention are possible. Particularly beneficial is here still that inside the the working medium for energy generation further core tubes arranged from finned tubes transporting global solar radiation which in turn transport the working medium for the heat pump. Man achieved this way in a more compact, cost-saving and technical way a combination of both possibilities for heat energy generation direct sunlight or from the ambient air according to the heat pump principle, only a single common housing is required.

In a further embodiment, this housing is in the form of an inverted one Y trained and sits with his two thighs astride the usual house roof shape used as a support surface.

Exemplary embodiments of the invention are shown in the drawing and are explained in more detail in the following description. Show it Fig. 1 is a cross-sectional view of arranged in a jointly mountable housing, System areas exposed to external influences for heat recovery from global solar radiation or according to the heat pump principle, FIG. 2 shows the representation 1 in plan view, FIG. 3 shows a further preferred embodiment of the present invention Invention in cross section, * praise. Combined finned tubes provided with core tubes intended for the transport of both working media of the two heat recovery systems Fig. 4 is an orizontal section through an absorber according to the representation 3 and 5 show the assignment of the outer ones as a schematic block diagram Partial to the Wärmespelchersvstem.

Description of the Examples of the Invention The representation of FIG. 1 in In connection with the top view of FIG. 2, a first possible exemplary embodiment can be found inferred from the invention. On a suitable surface, which prefers the roof 1 of a house can be, but also of everyone other suitable Support surface can exist, are the heat recovery device 2 for the Utilization of solar heat (using global solar radiation) and at least the evaporator area 3 of a second heat recovery system is arranged, which works on the principle of the heat pump and in the illustration of FIG. 1 on it prevents the heat content of the ambient or outside air from being used.

Both to the respective heat recovery systems (utilization of solar heat and utilization of ambient heat by heat pump) are in one together the support arrangement (roof 1) to be assembled structural unit 4 arranged, the in the illustrated embodiment, two separate compartments 5 and 6 forms with a partition 7 between the two parts. Both of an external influence (solar Subareas of the two heat recovery systems exposed to global radiation or ambient heat lead the 1 for thermal energy gained by their respective system to a common Heat storage / to, preferably by means of heat exchange, like the schematic diagram of Fig. 5 shows schematically. The heat accumulator can be compared to its surroundings accordingly well-insulated hot water storage tank inside the exchanger tubes belonging to the respective heat recovery system or in general Exchange facilities are located. It goes without saying that for the supply of the heat energy generated by each heat recovery system for the common storage 10 pumps are required that are switched on in the medium circuit. at the first heat recovery system aimed at utilizing global solar radiation, which works with absorber surfaces exposed to solar radiation becomes a simple circulation pump 103 is used, while the one that works on the principle of the heat pump second heat recovery system the fundamental Mode of action is different in that the heat energy generation is not based on the utilization an existing temperature gradient between that exposed to the external influence Part and the memory 1w, Sberuht, but a suitable medium, in the embodiment usually exposed to alternating evaporation and condensation will.

In the illustration of FIG. 1, this is based on the principle of the heat pump based second heat recovery system designed as an air heat pump and in one separate compartment 5 of the same structural unit 4 is arranged. In this compartment 5 are located a plurality of tubes 11, which form a coil system, and from the working medium are flowed through. The pipe coil system forms the evaporator of the air heat pump, i.e. that the working medium has a boiling point such that even at sub-zero temperatures in the degree Celsius range, for example down to -5 ° C, but possibly also at far lower temperatures (up to -300) a heat recovery from the ambient air is possible by the fact that the air by means of a suitable fan 12 through the evaporator 5, so that the Working medium evaporates in the tubes 11.

In a known way, heat is extracted from the environment by evaporation, which, when the working medium condenses, is released again elsewhere is and via the mentioned heat exchange with heat exchanger 122 within the memory 105 contributes to the heating of the domestic water located in this or this Warming also takes over on its own.

In the illustrated embodiment of FIG. 1, there are The pipes transporting the working medium of the air source heat pump in the evaporator area made of finned tubes, preferably finned tubes made of aluminum, so that a large attack surface for the evaporation of the working medium Ambient air is present. It goes without saying that the structural embodiment of the evaporator area of the second heat recovery system based on the heat pump principle is arbitrary; instead of a conventional radial fan 12, an axial fan can also be used Fan may be provided. The fan can be attached in a suitable position and can be designed as both a suction and a pressure fan.

In the exemplary embodiment, the fan is on the pressure side and pushes the ambient air sucked in by the fan blades 14 through the pipes 11 in the direction of a discharge louvre 15, which is under the pressure of the flowing Ambient air can open. Such a blowout blind can be made in a suitable shape In the closed state, overlapping and articulated slats are formed be.

At the top, the housing section 5 of the evaporator is transparent Material, for example glass or plexiglass 16 covered; the cover is in a bearing frame 17 held.

In an alternative embodiment, it is also possible to use the sloping surface Air stored on the roof area and possibly more heated there according to the direction the arrows A to suck in by a suitable blower, which is then installed at a different location and to be fed through the partition 7 to the evaporator tubes 11. In this case it can at 7 'a partition opposite the heat recovery device 2 of the solar system be arranged. On the basic operating principle of the heat pump, since it is known not to be discussed further, it is essential that the invention the combined application of the utilization of global solar radiation and the heat pump system proposes for the production of correspondingly warm domestic water, as it turned out has that in our latitudes the sole application of the solar principle, in particular in the weaker winter months, not the domestic water heat consumption covers, while in the summer months, when the solar operation in itself sufficient amounts of heat would make available, the heat requirement due to the lack of heating is low.

On the other hand, the second is used in the present invention Heat recovery system, which is based on the heat pump, able to work with lack of solar radiation heat energy, also from relatively cold ambient air, still to be won, so that the combinatorial application of both on a common hot water tank working systems is suitable that so far in the generation of heat energy still existing problems essentially increase to solve.

The heat recovery device or the absorber 2 for solar operation is in the representation of FIG. 1 in a separate housing compartment 6 inside of the common structural unit 4 and comprises a lower insulating layer 20 and a transparent cover 22 carried by the frame structure 21 and made of glass, Plexiglass or the like. Can exist. In the insulating layer 20, which is made of a suitable insulating plastic foam material can be made according to a feature In the present invention, finned tubes 25 that are separate from one another are embedded, arso tubes, which, like the top view of FIG. 2, shows from a heat-transporting medium pipe 26 through which it flows and annular disks 27 attached to this pipe exist.

The disks 27 can be formed in one piece with that of FIG and usually are, because the tubes 25 are preferably aluminum finned tubes, which are manufactured using a suitable casting process. Any aluminum finned tube 25 extends extends over the entire width of the housing section 6 at the specified distance from the other parallel pipes; mouth at the end the pipes then in a common collector or. Distribution pipe 28, 29. Above the A suitable vent 30 can also be arranged in the pipe 29. The representation 2 shows in the plane of the drawing on the left the top view of the two outer ones Heat recovery devices 2 and 3 exposed to the action with the cover omitted (transparent cover 22 or blind 15), while on the right of the illustration in the plane of the drawing blind 15 and cover 22 are in place. The evaporator finned tubes 11 of the heat pump are, as the figure shows, laid in the manner of a pipe coil, while the finned tubes 25 for solar operation a parallel, the solar radiation Form exposed tube bundle. As within the housing section 6 for the finned tubes 25 the space below the cover 22 is heated as a whole, is the Use of finned tubes (as opposed to the medium to be heated through flat and hollow blanks) particularly advantageous, because the individual Ribs of each finned tube create a much larger heat absorption surface, which is not only arranged in one plane like a flat board, but also extends in the depth direction of the housing section from the insulating layer to close to Cover extends. In this way, there is a particularly good level of efficiency in solar operation to reach.

The operation of both heat recovery systems can be simultaneous or timed be carried out separately as required, suitable Re-Rr ^ ra ellorl are gel and Control circuits that the temperature of the water contained in the memory with the Compare the temperature exhibited by the heat transport medium in the finned tubes 25. The heat pump with evaporator 5 is expediently used when the pure solar operation with the help of the finned tubes 25 none sufficient Is able to deliver more thermal energy.

In an advantageous embodiment of the present invention, it is also possible, the coil 11 of the evaporator area of the air heat pump within or to be attached in the region of the finned tubes 25, so that the housing compartments within the common structural unit 4 can be omitted. So it is possible, as indicated at 30, the finned tube coil 11 ′ of the evaporator into the one formed between the finned tubes 25 To arrange clearances above the insulation. There can be a considerable saving on required bearings and components, with one or two blowers at 31 and at 30 in the support frame 21 an air inlet opening is to be arranged, which if the fan is not in operation, it is expediently automatic opening and closing blind is locked. As soon as the solar operation No longer possible due to insufficient solar radiation or the temperature gradient no longer high enough to achieve sufficiently warm domestic hot water can be operated manually or preferably by automatic sensors on the heat pump are switched, in which case the housing 6 for the finned tubes 25 of the solar power at the same time with appropriate ventilation by means of fans or blowers as a housing for accommodating and operating the Vcrdarnuferschlangen 11 of the IJirmunne serves.

Another, particularly preferred embodiment of the present invention lies in the fact that the heat pump principle is operated indirectly via an intermediate medium which can be heated by solar heat and / or ambient air. With this one Embodiment, which in one possible application form in the representation 3 is shown, finned tubes 40 are used for the solar operation, the have further core tubes 41 in their interior, preferably concentrically which that Working medium, Frigen, flows through the heat pump. The working medium for solar operation then flows in the free annular space between the inner, Frigenleitenden Core tube and the jacket of the outer tube. This combined use of common, Finned tubes transporting both working media, again preferably made of aluminum, is particularly advantageous and also allows the use of the heat pump principle down to very low temperatures, because that for solar operation inside the finned tubes 25 or 40 fluent working fluid is not normal water, but a special one on the basis of water treated brine, which has a very low freezing point Has. Therefore, this brine is still liquid and permitted even at significantly below zero temperatures the extraction of heat by the vapor evaporating in the core tubes, whereby the thermal energy Via the brine in the finned tubes 40 for solar operation for evaporating Frigen got.

The finned tubes 40 and the brine flowing in them are then in turn heated either by solar radiation or the existing global solar radiation, if also in winter possibly only to a lesser extent and on the other hand through the ambient air flowing through the finned tubes and along the finned tubes.

In the embodiment of FIG. 3, a particular form of the common structural unit for the two system areas exposed to external influences, Finned tubes 40 for solar operation on the one hand and core tubes 41 for heat pump operation on the other hand, provided, namely a housing shape resembling an inverted Y, which is placed with the V-shaped opening on the roof ridge 42 of the building roof 43 can be. The housing parts accommodating the combined finned tubes with core tube can then be formed on both sides by the Y-legs 44a, 44b; It is also possible, only the one facing the solar radiation side (south or west side) Leg 44a of the housing structure with combined finned tubes to be filled and to train the other leg as a storage. Both legs whether these now contain finned tubes or not, run in a common upper part 46 together, in which a fan 48 covered by a hood 47 is arranged is. The fan can be in the form of a suction fan and sucks through one Flap 5D that opens and closes like a louvre It happens when the suction effect the fan fails) ambient air over the roof surface and drives it through the finned tubes. This is based on the extraction of thermal energy from the ambient air based operation begins when the heat energy generation process is achieved through recovery solar heat alone is no longer sufficient or the solar radiation is too low is.

If you only work with the first heat recovery system (recovery Solar heat), then the blind 50 in the lower part is closed, likewise one further cover flap 51 in front of the fan 48, so that not by a kind of chimney effect the heat content of the housing leg 44a is lost. As soon as the recovery of the Solar heat is no longer sufficient, i.e. no longer supplies sufficient thermal energy, is switched to the heat pump system, the louvre flaps 50, 51 open automatically either under the suction of the fan 48 or controlled by Relay or motor actuation when switching over and the heat pump is put into operation. In this case, it is also essentially an air heat pump, since it is the incoming ambient air that affects the finned tubes and that in them first located brine is heated, which then in turn dissipates the heat (practically without any loss) gives off to the evaporation medium Frigen of the air source heat pump, but it is possible that occasionally incident sun rays to heat the finned tubes 40 and thus contribute to the working medium flowing in the core tubes 41.

Such a system is particularly advantageous, apart from that, considerable reduced construction costs, which would otherwise be the case with two different heat recovery systems is necessary, also because with a pure air heat pump by the considerable Cooling due to evaporation of the working medium Outer surface of the finned tubes 11 occur, so that they freeze and the efficiency noticeably worse or the operation of the air source heat pump becomes completely impossible. Are however, the core tubes 41 with the Frigen within which the brine for solar operation arranged leading finned tubes 40, then the icing thaws on the finned tubes 40 by the global solar radiation alone at daybreak and the whole thing The system is ready for operation again, even if icing occurred during the night should be.

It is particularly advantageous in the embodiment of FIG. that a practically completely pre-assembled unit in the form of an upside down Housing similar to Y is used with an opening angle adapted to the angle of the roof can be that by omitting and thus saving the top roof tiles and the ridge of the roof is placed on the roof of the house; they then close, as with 55 shown, the roof tiles only start at a certain height. The legs of the case 44a and 44b have extensions 56a, 56b at the end, which the first one subsequent row of roof tiles at least partially overlap, so that a flawless Transition is achieved together with a rainproof seal.

The finned tubes 40 with core tubes 41 in the embodiment of FIG 3 can be laid and stored in the form of a continuous pipe coil; but it is also possible, likewise preferably coaxially nested on both end sides Arrange distribution and collector pipes. It goes without saying everyone Housing legs 44a, 44b sufficiently insulated at least in its lower part, so that no heat loss occurs in solar operation; the cover 58 of the legs is in any case transparent again and allows solar radiation energy to pass through.

A particularly advantageous one, with those exposed to external influences Storage device connected to subsystems can be designed so that for the Solar system utilizing the radiation of solar energy directly to generate heat a large storage tank for only a relatively low temperature, for example 400, storage medium to be heated is provided. From this large storage area (Storage capacity 50 to 80 m3, for example) is taken from a storage tank for a higher temperature, for example 600 C, heat energy via a hot water heat pump; another Heat pump, which the evaporator 3 or the core tubes 41 in the embodiment the Fig. 3 can be assigned, works directly on the high-temperature buffer. This would be an exemplary possibility, like the combination system from solar Heat absorption and heat absorption from the ambient air by means of a heat pump together can work on the consumer sector.

Is used in the hot season exclusively according to the principle of Heat recovery from global solar radiation worked, then it can turn out to be In the case of the combination finned tubes from the core tubes, the working fluid proves to be useful for the heat pump area can be deducted, which can easily be done using suitable systems is possible.

Fig. 4 shows an embodiment of a Yernrohre in surrounding Corrugated tubes having absorber in a horizontal sectional view; the Absorber from wiq. 4 can therefore also show the horizontal sectional view of the housing 44a of Fiq. 3 be, however, with the exception that in whole or in part the special Y-housing shape can also be dispensed with. The housing or the Housing leg 70 of FIG. 5 is box-shaped and contains in parallel Arrangement of finned tubes 71, which are connected at the end with inlet 72 and outlet 73. Through the finned pipes and thus also partially in the inlet and outlet area penetrating, a closed pipe coil 41 extends as a core pipe inside the finned tubes for solar operation; the pipe coil 41 is for the heat pump area determines and maintains the Frigen used as the preferred health remedy. The influx the ambient air takes place at 75 through a blind that is open when the heat pump is in operation 76. In the present exemplary embodiment, two C, ehl.; Se 77 are provided, suck in the ambient air through the absorber and through a blind on the outlet side 78 eject again. The inflow of brine for solar operation takes place at the inlet connection 79, the drain at outlet 80, while the frig at inlet 81 of coil 41 is supplied and discharged again at 82. In an expedient embodiment In addition, the actual tubes in the absorber area can be used as the core tubes and the finned tubes surrounding these are made of copper, while the fins are on the finned tubes made of another, preferably highly thermally conductive material such as Aluminum, made and pushed onto the copper tubes that support these fins and are soldered, for example.

The overall flow diagram given in FIG. 5 for better understanding includes the Ahsorher 100, the ribbed pipes 101 for solar operation and evaporator pipes 102 for the working medium of the (air) heat pump. The absorber 100 can be structurally constructed like the embodiment of FIG. 1 with separate Finned tubes for the solar absorber and evaporator tubes for the air heat pump or as shown in combined form in the embodiment of FIGS. 3 and 4, with core tubes arranged inside the finned tubes with 103 is the circulation pump for the brine of the solar circuit, with 104 the lizhündel within of the heat exchanger / storage tank 105 and with 106 the immersion sensor for the storage tank temperature emerging.

The overall system of FIG. 5 comprises three mutually independent, possibly but control systems 110 working in mutual coordination for solar operation, 111 for heat pump operation and 112 for the consumer area. The rule system Various sensors are assigned to 110, 111 and 112; the control system 110 for the solar area also has a solar temperature sensor 107, as well a vent 108 is provided, a safety valve 109 and a membrane expansion vessel 115. The mentioned components 101, 103, 104, 106, 107, 108, 104, 115 with controller 110 constitute the solar charging area; the air heat pump area is formed from the already mentioned evaporator tube 102, one controlled by the associated controller 111 Fan 120, a compressor 121 for circulating the working medium and a heating bundle condenser 122 within the heat exchanger / heat storage tank 105. The Heat pump area through a pressure reducing valve 123 and an air temperature sensor 124, which can be set to switch off heat pump operation via the controller. At 130 Any consumers or buyers within the area are intended for which the entire system works, i.e. radiators, boilers and the like. The consumers are fed by a circulation pump 131 in the slave circuit. The consumer area further comprises a flow sensor 132, a mixing valve 133, a weather sensor 134 as well as a safety valve 135 with a diaphragm expansion vessel in this circuit 136.

Alternatively, the heat storage system 105 works on the heat exchanger, if necessary also in combination with the solar charging system or the air heat pump area, each controlled by their own control loops 110 and 111. The controller 110 switches the brine circuit each time the solar temperature sensor 107 has a higher temperature as the immersion sensor 106 in the hot storage tank 105 indicates; the Controller 111 for the air heat pump area. It can be useful to run the respective controllers 110, 111 to synchronize with one another, like those in both directions indicating working signal connecting line 140 between the two controllers.
