Description

KLIM ATIS ATIE DEVICE G

This invention relates to a climatization device comprising a solar collector for heating a gas and / or a liquid with the aid of sunlight.

Such solar collectors are usually used for heating either air or water, or a combination of both. The warm air and / or the warm water can then be used for heating rooms, (tap) water, etc.

More specifically, but not limitingly, this invention also relates to air-conditioning devices for which the inventor also requested protection in Belgian patent application BE-2008/0558. For all the specific advantages and details of such climate control devices, reference is made to this patent application, for which priority is given to the current patent application. Consequently, the content of BE-2008/0558 should be considered as an integral part of the current patent application. The invention from the current patent application 20 has already been described in respect of these air-conditioning devices from BE-2008/0558 in BE-2008/0558.

As traditional energy sources become increasingly scarce, it becomes increasingly necessary to use alternative energy sources. Solar energy provides an energy source that is still not used enough. This invention therefore wants to greatly increase the possibilities for using solar energy.

A major disadvantage of existing air-conditioning devices that comprise solar collectors is that solar energy is thus not used to cool rooms from, for example, a home. Many solar collectors are already known that either heat air currents or water currents in order to heat a building 1037355 2. However, when one can extract most heat from the solar energy, namely in the summer, one needs the least heating of a building. Air-conditioning devices with solar collectors which do have the option to cool rooms, either actively use an air-conditioning system that is usually powered by electricity, or, such as for example the air-conditioning device described in US 2005/199234, cool the air rooms only when no light enters the solar collector, such as in the evening and / or at night, where they use the cooled outside air to cool the rooms.

10

The object of this invention is therefore to provide such a climate control device in which it is possible to use the gas heated by the solar collector and / or the liquid heated by the solar collector in order to be able to cool spaces with it.

15

This object of the invention is achieved by providing a climatization device comprising a solar collector for heating a gas and / or a liquid with the aid of sunlight, wherein this climatization device comprises an absorption cooling device, said absorption cooling device comprising a boiler 20 for boiling up an absorption liquid and wherein this climatising device is provided with guiding means for guiding the gas heated by the solar collector or the liquid heated by the solar collector along the sleeve to use this heated gas or this heated liquid as heat source for the boiling up the said absorption fluid in the boiler.

With this climate control system, one can now use solar energy to heat spaces to the maximum in the winter, while in the summer one can use solar energy to the maximum to cool those same spaces.

In a specific embodiment of a climate control device according to the present invention, said gas is air.

The said fluid of a climate control device according to the present invention is more specifically water. For example, glycol could also be used as a liquid.

When the solar collector of a climate control device is used to heat up water or glycol, in a first specific embodiment this solar collector preferably comprises a tube system through which the water flows to heat this water with the aid of the solar collector incident on the solar collector sunlight, an inlet for supplying water to this tube system and an outlet for draining water from this tube system and the air-conditioning device comprises a guide tube as a guide means for guiding the heated water from said outlet to the boiler.

In a second specific embodiment of such a climate-control device in which the solar collector is used to heat up water, the solar collector comprises an absorption plate which is flushed with water and which comprises an inlet for supplying the water to this absorption plate and a outlet for draining water from this absorption plate and wherein the air-conditioning device comprises a guide tube as guide means for guiding the heated water from said outlet to the boiler.

Naturally, such a climate control device, comprising a solar collector that can heat both water and air, is also part of the possible embodiments of climate control devices according to the present invention.

An even more preferred embodiment of a climate control device 30 according to the present invention comprises a heat pipe, the first end of which is exposed to sunlight and the second end of which is arranged along the sleeve 4 in order to supplement the heat displaced by the heat pipe taken from the sunlight. use a heat source for boiling up the said absorption fluid in the boiler.

Even more preferably, such a climate control device therefore comprises a hollow spherical mirror, which is arranged with respect to the heat pipe, so that sunlight incident on the hollow spherical mirror is reflected towards the first end of the heat pipe.

In a special embodiment of a climate control device according to the present invention, the sleeve of the absorption cooling device is arranged in the solar collector itself.

Preferably a climate control device according to the present invention is one of the many embodiments of climate control devices as described in BE-2008/0558, which is provided with an absorption cooling device and with means for heating the water and / or heated by means of the solar collector. to use the air heated with solar collector as a heat source for boiling up the absorption liquid in the boiler of the absorption cooling device.

The air-conditioning devices (1) according to the present invention, as shown in Figures 5 and 8 to 12, comprise a solar collector (50) for heating air and water. Furthermore, these air-conditioning devices (1) comprise an absorption cooling device (51), some possible embodiments of which have been shown separately in Figures 1 to 4.

Solar collectors (50) for heating up air and / or water are already known, so that this is not discussed much deeper. For a climate control device (1) according to the present invention, solar collectors (50) as described in the Belgian patent application BE-2008/0558 of this inventor are particularly suitable, since solar energy can be used to a maximum with the aid of these solar collectors (50) to heat up air and / or water. The detailed description of these solar collectors (50) from BE-2008/0558 should be considered as an integral part of the current detailed description for the advantages and specificities of these solar collectors (50).

Such absorption cooling devices (51) in each case comprise a boiler (52), a condenser (32), an evaporator (35) and an absorber (53). These absorption cooling devices (51) comprise closed circuits filled with, for example, ammonia, water, hydrogen and aqueous ammonia solutions.

In the absorption cooling devices (51) shown in Figs. 1 to 4, the water heated by the solar collector (50) is guided in each case by means of a guide tube (55) along the sleeve (52) around this heated water or this heated water air to be used as a heat source for boiling up the absorption liquid (for example, a solution of ammonia in water) in the boiler (52). The boiler (52) is in each case also provided with an electrical resistor (62) to heat up the solution if coolness is desired when 9 insufficient solar energy is present. A heat pipe (59) can also be provided to extract extra heat from the solar energy. Such a heat pipe (59) was not shown in Figures 1 to 4, but is further discussed.

The ammonia partially evaporates from this solution in the boiler (52) and rises to the condenser (32). This condenser (32) can be a water or glycol-cooled condenser (32), as shown in Figures 1 and 3, or can be an air-cooled condenser (32), as shown in Figure 2.

10

A solution with a lesser concentration of ammonia in water runs into the boiler (52) under the influence of gravity via the return (76) in the absorber (53).

In the condenser (32) the ammonia condenses and flows in liquid form towards the evaporator (54). For example, the evaporator (54) is filled with hydrogen, in which the liquid ammonia evaporates, the ammonia absorbing heat from its environment. This environment is cooled in this way. Here, glycol is used as the coolant, with heat being extracted from the glycol in the evaporator (54). Water could also be used as coolant. As shown in Figures 3 and 4, this absorption cooling device (51) can be worked out, for example, in two parts. The majority, as shown in Figure 3, can then, for example, be incorporated in a panel together with the solar collector (50), which is arranged in an outside environment where it can be exposed to sunlight. This part of the absorption cooling device (51) can then, for example, be built into the solar collector (50) as shown in Figure 5. The part with the heat exchanger (78) of the evaporator (54), as shown in figure 4, can then be arranged, for example, in an indoor environment, and this, for example, between the air inlet (3) and the air outlet (4) of the solar collector (50) In addition, a pump (65) can then be used to circulate the glycol or water in this heat exchanger (78). Additionally, an additional fan (66) can also be provided here, in which way the cooled glycol or the cooled water from the evaporator (54) is sent via the pump (65) through the heat exchanger (78), which absorbs heat more quickly with the aid of the fan (66). Both said pump (65) and the additional fan ( 66) are preferably driven by means of a thermostat 5. Figure 4 shows the air inlet (3) and the air outlet (4) of the solar collector (50) of this climate control device (1). 3) and air outlet (4) naturally depends entirely on the construction of this solar collector (50). Depending on the solar collector (50), the air inlet (3) can, for example, be placed equally well in the middle below this heat exchanger and the air outlet (4) can also be equally well in the middle above this heat exchanger, depending on the solar collector (50) are placed.

The mixture of hydrogen and ammonia then enters the absorber (53) from the evaporator (54). The solution with a lesser concentration of ammonia in water also arrived via reflux (76). This solution absorbs the ammonia from the evaporator (54), whereby the hydrogen can rise back to the evaporator (54). In this way again a solution with a higher concentration of ammonia flows into the absorption vessel (61) and from there into the boiler 20 (52). The absorber (53) can optionally be provided with an additional heat exchanger (64), as shown in figure 1, which is for example flowed through with cooling water or with glycol.

As mentioned, in the absorption cooling devices (51) shown in Figs. 1 to 4, the water heated by the solar collector (50) is guided in each case with the aid of a guide tube (55) along the boiler (52) around this heated water or use this heated air as a heat source for boiling up the absorption fluid in the boiler (52). This guide tube (55) may, for example, be connected to a water-permeable absorption plate (2) of a solar collector (50), or may be connected to a tube system (31) of a solar collector (50) as shown in Figure 6. This illustrated pipe system (31) 11 comprises an inlet (73) for supplying water to this pipe system (31) and an outlet (74) for draining water from this pipe system (31). The guide tube (55) guides the water heated in the tube system (31) from the outlet (74) to the boiler (52) and back to the inlet with the help of sunlight warmed up to the solar collector (50). The water is hereby pumped around with the aid of a pump (65) which is preferably controlled with the aid of a thermostat.

In these air-conditioning devices (1), in which water heated by the solar collector (50) is used as a heat source for boiling up absorption liquid in the boiler (52), it is advantageous to also use the heated water depending on the needs. for other purposes. For this purpose, a valve (72) is shown in Figure 6, with which the supply of water from the pipe system (31) to the boiler (52) can be opened or closed. Additional valves (71) can then be provided to open or close the heated water supply to, for example, a boiler for use of the hot water in a central heating system or for use of the hot water as sanitary water, or for supply to buffer means, such as a buffer vessel, in groundwater or in soil, to subsequently recover this buffered heat with the aid of a heat pump, or for generating electricity using the principle of a Stirling engine, etc.

Figure 5 shows how some parts (52, 32, 75) of an absorption cooling device (51) and of a solar collector (50) can be built into a climate control device (1) according to the present invention. The solar collector (50) comprises an absorption plate (2) and an air flow space (75), which is located along the absorption plate (2). The sleeve (52) is arranged in a space (56) adjacent to this airflow space (75), which is provided with an air inlet (57) for supplying air from the air flow space (75) to this space (56) and an air outlet (58) ) for exhausting air from this space (56).

The boiler (52) is also provided with an electrical resistor (62) to heat up the solution if cooling is required if insufficient solar energy is present. A heat pipe (59) is also provided to extract extra heat from the solar energy. This heat pipe (59) is exposed to incident sunlight at its first end. Liquid in this heat pipe (59) is hereby heated and evaporated. This vapor flows to the second end of the heat pipe (59) under the influence of the pressure difference that arises in the heat pipe (59). At the second end, this vapor condenses, releasing heat into the environment. Here the second end is arranged against the boiler (52), so that the heat that is released when condensing the vapor is used to boil up the absorption liquid. The back condensed liquid 10 flows back into the heat pipe (59) as a result of the pressure difference to the first end of the heat pipe (59), where it is again exposed to the sunlight to evaporate again.

When the heat from the heat pipe (59) is not used for the absorption cooling, this heat can be used as an additional source of heat for producing with the aid of the air inlet (57), the space (56) and the air outlet (58) hot air or hot water using the solar collector (50).

Such a heat pipe (59) is especially useful where the solar collector (50) is not placed at an angle, so that sunlight incident on it cannot be used to the maximum during the entire year. This is usually during the summer when the sunlight is almost perpendicular to the earth. The heat pipe (59) can then be positioned in such a way that the sunlight that does not fall on the solar collector (50) at a correct angle, is reflected back to the heat pipe (59), so that the solar energy can still be used to the maximum for cooling a home for example. In the air-conditioning device (1) as shown in Figure 9, such a placement of a heat pipe (59) with respect to a solar collector (50) is shown.

In figure 5, further, the water-cooled condenser (32) of the air-conditioning device (1) is installed in a space above the solar collector (50). This condenser (32) could just as well be an air-cooled condenser (32). The tube that brings the solution warmed up by the boiler (52) to the condenser (32) is built into a space adjacent to the solar collector (50). This tube is pre-cooled with the aid of outside air, which flows into this space via inlet (69) and flows out of this via outlet (70), so that a part of the water from this solution already condenses. Instead or additionally, fins could also be provided on this tube so that it is air-cooled.

The different embodiments of a climate control device (1) according to this invention as shown in Figs. 5 and 8 to 10 each comprise a frame that is fixed on the outside against an outside wall of a room to be climate controlled. This frame is made of metal or plastic, or any other material that is eligible for this. The space to be air-conditioned is a space that, for example, needs to be heated, or needs to be cooled, or a space whose air needs to be dried, etc.

Away from the outer wall, this frame is bordered by a light-transmitting plate (17), which is provided for transmitting solar radiation. Edge insulation (16) is provided on the side edges of the frame. An absorption plate (2) is provided at a certain distance from the light-transmitting plate, which plate is partially enclosed at its edges in the edge insulation (16). A greenhouse effect is thus created between the light-transmitting plate (17) and the absorption plate (2), whereby heat is accumulated and the absorption plate (2) can absorb maximum heat from the sun's rays.

The light-transmitting plate (17) is preferably made of glass, and more preferably in the form of a double glass, and furthermore preferably provided with a reflective layer.

The absorption plate (2) is made of a heat-absorbing material and is preferably a metal plate and even more preferably a black corrugated plate, as in the illustrated embodiments.

14

On the opposite side of the absorption plate (2) than the light-transmitting plate (17), an insulating plate (6) is provided at a certain distance from this absorption plate (2). The surface of this insulation plate (6) that faces the absorption plate (2) is heat-reflecting.

In the embodiment from Figure 5, this insulation plate (6) shields the frame.

In the embodiments from figures 8 to 11, this insulating plate (6) 10 is mounted centrally in the frame. At the rear, this frame is then provided with a second insulation plate (23). Between the two insulation plates (6,23), the evaporator (35) of the absorption cooling device (51) is arranged between a metal plate (33) and a corrugated plate (34).

Furthermore, the air-conditioning devices (1) of figures 5 and 8 to 11 comprise an air inlet (3) for supplying air and an air outlet (4) for discharging air.

The waves from the corrugated plate (2) define air flow channels (5) for flow of air between the air inlet (3) and the air outlet (4). The air flow channels (5) are not channels in the strict sense, but rather guide paths that determine the main flows of air between the air inlet (3) and the air outlet (4). These air flow channels (5) open into expansion spaces (9).

25

The air flows between the absorption plate (2) and the insulation plate (6) and between the absorption plate (2) and the light-transmitting plate (17).

To this end, the absorption plate (2) in the condition of use of the air-conditioning device (1) is enclosed at its side edges in edge insulation (16), wherein an airflow space (22) is provided between its upper edge and the frame and between its lower edge and the frame. to provide. The absorption plate (2) is hereby supported in the frame with one or more supports, which were not shown.

Furthermore, for this purpose the air inlet (3) is provided above the air outlet (4), an air block (18) being provided between the insulation plate (6) and the absorption plate (2), between the air inlet (3) and the air outlet (4) . The inlet diffuser (7) is then provided between the insulation plate (6) and the absorption plate (2) on the opposite side of the air inlet (3), then the air block (18) and the outlet diffuser (8) between the insulation plate (6) and the absorption plate (2) on the opposite side of the air outlet (4) than the air block (18).

Therefore, air is forced to flow completely around the absorption plate (2), so that the heat transfer between the absorption plate (2) and the air flowing through occurs on both surfaces of the absorption plate (2). Heat transfer is therefore greatly increased compared to solar collectors where only heat transfer to one surface of the absorption plate (2) is provided.

After the air inlet (3), at the beginning of the air flow channels (5), an inlet diffuser (7) is provided, to distribute the supplied air evenly over the air flow channels (5) and thus over the absorption plate (2). For the air outlet (4), at the end of the air flow channels (5), an outlet diffuser (8) is provided to guide the air that these air flow channels (5) have flowed through to the air outlet (4).

In the embodiments from figures 8 to 11, an air flow space (22) is also provided between the upper edge of both the metal plate (33) and the corrugated plate (34) and the frame. A space is provided between the first insulation plate (6) and the metal plate (33), so that air can flow around the whole of evaporator (35), metal plate (33) and corrugated plate (34). In the gap 30 between the corrugated plate (34) and the second insulating plate (23), an air block (18) is also provided between the air inlet (3) and the air outlet (4). Here too, an inlet diffuser (7) and an outlet diffuser (8) are provided.

The air blocks (18) of the embodiments from figures 5 and 8 to 11 are preferably provided for discharging condensed water to the underside of the space between the absorption plate (2) and the insulation plate (6), where a condensate collector with condensate outlet (14). With the air block (18) shown here, condensed water is led to the sides of the air block (18) and drained there.

10

The air inlet (3) of these air-conditioning devices (1) is each provided with a fan (10) for pumping the air around in the solar collector (50). Furthermore, this air inlet (3) can be provided with concentric rings to damp the noise of the fan (10). This air inlet (3) can also be provided with a pollen filter or with a dust filter.

The air outlet (4) is preferably provided with a non-return valve which automatically closes to prevent heat recoil and thus to prevent a cold fall.

The air inlet (3) and the air outlet (4) are preferably also provided towards the room to be air-conditioned with grilles (24) which can regulate the supply and discharge of air and, if desired, completely close off.

The air-conditioning device (1) is preferably also provided with an inlet for fresh air.

The air flow channels (5) can also be provided with, for example, helical or boomerang-shaped obstructions for maximally distributing the air over the absorption plate (2).

30 17

In the embodiment of a climate control device (1) as shown in Fig. 8, the air-cooled condenser (32) of the absorption cooling device (51) is installed on top of the solar collector (50) in a space provided for this purpose. Instead of this air-cooled condenser (32), such a climate control device (1) can equally well be provided with a water or glycol-cooled condenser (32), as shown in Figure 11. Both in the embodiment of Figure 8 and this from Figure 11, the sleeve (52) of the absorption cooling device (51) is built under the solar collector (50) in a space provided for this purpose.

In the embodiment as shown in Figure 9, the sleeve (52) is built into the solar collector (50) itself. In this embodiment, an air-cooled condenser (32) was also installed in a space on top of the solar collector (50). Equally well, this air-cooled condenser (32) could also be replaced by a water or glycol-cooled condenser (32).

15

Such a climate control device (1) as shown in Figs. 8, 9 and 11 are particularly suitable for placing under a slope, so that sufficient sunlight always falls on the solar collector (50) when the sun shines. Where it cannot be placed under a slope, it is more advantageous to install a climate control device (1) as shown in figure 5 or 10. This also includes a heat pipe (59) that is built into a space delimited with glass (77) that is placed under a slope, so that sunlight will always fall on it when the sun shines. This glass (77) can also be advantageously designed double-sided and provided with a reflective layer on the inside, in order to create a greenhouse effect in the space of the heat pipe (59). Furthermore, as shown, a hollow spherical mirror (60) is preferably placed in this space relative to the heat pipe (59) such that incident sunlight is reflected on it towards the heat pipe (59).

The air-conditioning device (1) from figures 5 and 10 are also provided with a water or glycol-cooled condenser (32). These could equally well be provided with an air-cooled condenser (32). In these embodiments, the boiler (52) is re-installed in a space below the solar collector (50), the heat pipe (59) being arranged in that same space.

The installation of the absorption cooling device (51) in such air-conditioning devices (1) as shown in Figures 8 to 11 is further clarified by the different successive layers of such a air-conditioning device, as shown in Figures 12a l to discuss.

Figure 12a shows the light-transmitting plate (17) of the solar collector (50), which is preferably double-glazed, provided with a reflective layer. At the bottom of the solar collector (50) a space is provided in which the sleeve (52) is arranged, together with the heat pipe (59). This is therefore an illustration of this layer in a climatization device (1) as shown in figure 10, which is provided with a boiler (52) and a heat pipe (59). This sleeve (52) and heat pipe (59) are no longer shown in the following figures 12b-1.

Figures 12b to 12e show a double-walled corrugated plate as an absorption plate (2), which is internally provided with a water-permeable pipe system (31).

20

Figure 12b shows the first wall of the corrugated plate (2) and Figure 12e shows the second wall of the corrugated plate (2). An airflow space (22) is provided both between its upper edge and the frame and between its lower edge and the frame to allow air to flow around the corrugated plate (2). The double-walled corrugated plate 25 (2) is hereby supported with the aid of supports which were not shown.

Figure 12c shows a possible water-flowable tube system (31) and an air-cooled condenser (32), which is arranged above the solar collector (50). Figure 12d shows the same water-permeable pipe system (31) and a water-cooled condenser (32), which is arranged above the solar collector (50). The 19 layers from these figures therefore do not occur together in the air-conditioning device (1), but depict alternative embodiments. The condensers (32) were only shown in these figures and not repeated in the other figures. Optionally, solar cells can be provided on the sun-facing side of the condenser (32) to provide the control of the absorption cooling device (51) for electricity extracted with the aid of solar energy. In this way the entire climate control device (1) can again run on solar energy.

Many variants of such a tube system (31) are possible. The double-walled corrugated plate (2) could also be designed in such a way that it is water-permeable. A single-walled corrugated sheet (2) against which a water-flowable tubing (31) is arranged could also serve as an alternative. This part of the air-conditioning device (1) is provided to be used to produce hot water. With the pipe system (31) from figure 12c, it is possible to let water run through this pipe system (31) on the basis of the thermosiphon principle. A water pump can also be installed to pump the water through this pipe system (31). This water pump can, for example, be controlled with the aid of a thermostat.

The hot water that is produced in this way can be used directly in a central heating system. However, this can also be buffered in a buffer tank, in groundwater or in soil to be recovered with the aid of a heat pump, etc. The necessary buffer means then form part of the air-conditioning device (1). In the absence of sunlight, it can then also be used as a radiator by sending the buffered heat back through the tube system (31) using a medium. The heat produced could also be used to generate electricity using the principle of a Stirling engine or could be used as domestic hot water, etc.

Figure 12f shows the air inlet (3), an inlet diffuser (7), the air outlet (4) and an outlet diffuser (8) of the solar collector (50), with an air block 20 (18) in between. Dotted line also show the air inlet (3) and the air outlet (4) of the part of the air-conditioning device (1) shown in Figures 12h-1. The air block (18) is here centrally provided with a drain to drain condensed water to the bottom of the space between the absorption plate (2) and the insulation plate 5 (6). A condensate trap and condensate outlet may also be provided, but were not shown here.

Figure 12g shows the insulation plate (6) of this climate control device (1).

Figures 12h-j show the evaporator (35) of the absorption cooling device (51), which is provided on one side with a metal plate (33) and on the other side with a corrugated plate (34). An airflow space (22) is provided between the upper edge of both the metal plate (33) and the corrugated plate (34) and the frame and between the lower edge of both the metal plate (33) and the corrugated plate (34) and the frame.

Figure 121 shows the second insulation plate (23) of the air-conditioning device (1). A certain gap is provided between the first insulation plate (6) and the metal plate (33), so that air can flow around the whole of evaporator (35), metal plate (33) and corrugated plate (34). In the second insulation plate (23) an air inlet (3) and an air outlet (4) are provided for the part of the air-conditioning device (1) shown in Figs. 12h-1.
