Description

CLIMATIZATION DEVICE

The invention relates to a climatization device comprising an air-flowed solar collector, said solar collector comprising - an absorption plate; comprises an air inlet for supplying air; - comprises an air outlet for discharging air; comprises air flow channels located along the absorption plate, for flow of air between the air inlet and the air outlet, said solar collector after the air inlet being provided at the beginning of the air flow channels with an inlet diffuser which is provided around the air flow channels evenly over the air flow channels and so distribute over the absorption plate.

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 being used sufficiently. This invention wants to greatly increase the possibilities for using solar energy.

Existing air-flowed solar collectors usually comprise a heat-absorbing surface as an absorption plate. An airflow-through space, which is usually formed by different channels, is then provided on one side of this heat-absorbing surface. Air from a space to be heated flows into the channels via an air inlet, heats up when the said channels flow through and leaves these channels via an air outlet. Insulation is also provided on this one side. The other side of the absorption plate is provided to absorb the heat from incident solar radiation. A light-transmitting plate is provided on this side at a certain distance from the absorption plate, which is usually made of glass. In this way, with solar radiation incident on the glass, a greenhouse effect is created in the space between the glass and the absorption plate. Heat is accumulated so that the absorption plate can absorb maximum heat.

The known solar collectors, however, still cannot be used as a fully-fledged alternative to conventional heating devices, because after maximum absorption of heat through the absorption plate, the heat transfer to the air flowing through the channels remains too limited. In this way, a large capacity of solar energy is not utilized with these existing solar collectors.

With solar collectors where an inlet diffuser is provided to distribute the supplied air evenly over the air flow channels and thus over the absorption plate, as described for example in US 4 122 828, DE 29 22 678 and US 4 471 758, the solar energy capacity becomes already used better. However, in practice it appears that a considerable part of the solar energy capacity is still unused in this way.

It is therefore an object of this invention to further increase the heat transfer from the absorption plate to the air flowing through a solar collector.

This object of the invention is achieved by providing a climate control device comprising an air-flowed solar collector, said solar collector comprising - an absorption plate; - comprises an air inlet for supplying air; - comprises an air outlet for discharging air; - comprises air flow channels located along the absorption plate, for flowing air between the air inlet and the air outlet; said solar collector after the air inlet, at the beginning of the air flow channels, being provided with an inlet diffuser which is provided to distribute the supplied air evenly over the air flow channels and thus over the absorption plate and wherein the inlet diffuser forms an obstacle that each of the air flow channels shielded over a certain length, wherein airflow channels at the height of the air inlet are partially screened off over a greater length than the airflow channels located farther from the air inlet.

By better distribution of the air over the absorption plate with the aid of this inlet diffuser, the heat transfer from the absorption plate to this air is considerably increased.

In this patent application, air flow channels should not be understood in the strict sense of channels, but rather as conduction paths that determine the main flows of air between the air inlet and the air outlet. Secondary flows between the air flow channels are possible here. The meaning of this becomes even clearer in the further description of this invention.

The inlet diffuser here forms an obstacle that partially shields each of the air flow channels, whereby the air is not only uniformly distributed over the air flow channels, but additional turbulence is created, so that all air flowing through the air flow channels can come into contact with the absorption plate. Namely, with laminar flow of the air, only the air layer adjacent to the absorption plate will be able to absorb heat and gradually transfer this heat to the further air layers. In the event of turbulence, the heat from the absorption plate is more rapidly distributed over the full air volume in the air flow channels.

Because the inlet diffuser shields each of the air flow channels over a certain length, whereby air flow channels at the height of the air inlet are partially shielded over a greater length than the air flow channels located farther from the air inlet, also in the zones further away from the air inlet absorption plate sufficient air flow ensured.

Preferably, said air flow channels run parallel to each other along the absorption plate in order to allow the air to flow from the air inlet to the air outlet as quickly as possible in order to further maximize the heat transfer.

Preferably, the inlet diffuser partially shields the air flow channels in a zone away from the absorption plate. In this way the air can flow between the inlet diffuser and the absorption plate. Also at the level of the inlet diffuser, contact between the air and the absorption plate remains assured, so that here too heat is transferred.

Even more preferably, the length of shielding by the inlet diffuser in an airflow channel at the level of the air inlet is maximum, and the length of shielding in the other airflow channels decreases proportionally to the distance of the airflow channel in question from the air inlet relative to the maximum length. These lengths will then assume a substantially triangular shape. However, these lengths could equally well assume an arcuate course, or any other course that allows a good distribution of the air over the air flow channels and thus over the absorption plate.

In order to allow the air to flow out of the solar collector again as smoothly as possible after flowing through the air flow channels, a climate control device according to this invention is furthermore preferably provided, before the air outlet, at the end of the air flow channels with an outlet diffuser which is provided to guide the air from the air flow channels to the air outlet.

By first allowing a smooth flow, it is then possible to control the air flow through the air-conditioning device, for example with the aid of fans and / or with gratings that can control the supply and removal of air, according to the desired climate in a room to which the air-conditioning device is connected. The regulation of the air flow rate can for example be controlled with the aid of a thermostat.

In a preferred air-conditioning device according to this invention, the outlet diffuser partially shields the air flow channels at their end, corresponding to the shielding by the inlet diffuser at the start of the air flow channels.

Preferably, the air flow channels of a climate control device according to this invention are further partially limited by the absorption plate, so as to ensure contact between the absorption plate and the air flowing through the air flow channels without intermediate material.

The absorption plate is preferably made from a heat-conducting material. In a specific embodiment of a climate control device according to the present invention, this absorption plate is a corrugated plate, each wave of the corrugated plate partially defining a respective air flow channel. Thanks to the corrugated surface of a corrugated sheet, heat from sun rays coming in at different angles can be well absorbed. A serrated surface could also serve as an alternative to a corrugated surface. The use of a corrugated plate as an absorption plate makes it easy to manufacture a climate control device according to the present invention. For example, a climate control device according to the present invention can also be manufactured on the basis of standard materials that are freely available on the market. This corrugated sheet is then preferably black in order to allow maximum heat absorption from the incident solar radiation.

The air flow channels are furthermore preferably partially bounded by an insulating plate. This insulation plate is then preferably made thinner at the level of the inlet diffuser and / or the outlet diffuser, so that it is located farther away from the absorption plate than over the rest of its surface. This insulation plate is even more preferred with grooves, each groove partially shielding a respective air flow channel. The inlet diffuser and / or the outlet diffuser are therefore preferably provided with grooves, the grooves in the inlet diffuser and / or the outlet diffuser being deeper than those in the insulation plate.

The surface of the insulation plate that faces the absorption plate is designed to be heat-reflecting. In this way, no absorbed heat is dissipated by incorporation into the insulation plate. This insulation plate can, for example, be heat-reflecting with the aid of a heat-reflecting foil. It may equally well be provided, for example, with a heat-reflecting coating.

Furthermore, the air flow channels are preferably partially limited, whereby they further open into a common expansion space. In this way, air flow between the air flow channels is also possible. In this way, air can flow over all points over the entire surface of the absorption plate. Where air flow channels are channels in the strict sense of this word, the air flowing through, in the intermediate zones between the zones where the absorption plate forms a boundary for these air flow channels, never comes into contact with this absorption plate. By not fully limiting the air flow channels and allowing air flow between the air flow channels themselves, this becomes possible. A heat transfer between the absorption plate and the air flowing through is then also realized in the said intermediate zones.

In order to further optimize contact between the absorption plate and the air in the flow of the air flow channels, the air flow channels in a further preferred embodiment of a climate control device according to the present invention are provided with helical obstructions with great pitch along their length. These helical obstructions can also form the desired turbulence to ensure maximum contact between the absorption plate and the air. They are also sound-damping. These helical obstructions can here for instance be manufactured from sheet metal, or from plastic, or from any other suitable material.

As an alternative to the helical obstructions, in another preferred embodiment, the air flow channels are distributed throughout their length with different boomerang-shaped obstructions that cause the air to turn and spread. Such boomerang-shaped obstructions can be manufactured even more simply than helical obstructions.

In order to make the air flow through the solar collector even smoother possible, an air inlet guide is provided between the air inlet and the air flow channels and / or an air outlet guide is provided between the air flow channels and the air outlet.

In a specific embodiment of a climate control device according to this invention, the absorption plate is contained in a frame, wherein in this frame the absorption plate is contained at its edges in edge insulation, on one side of the absorption plate at a certain distance said insulation plate is provided and a light-transmitting plate is provided at a certain distance on the other side of the absorption plate as the front side of the frame, wherein the frame between the light-transmitting plate and the absorption plate is provided along the edges through the edge insulation with one or more ventilation holes, the frame at the bottom of the edge insulation is provided with a condensation trap with a condensation outlet and with the air inlet and the air outlet at the back through the frame and through the insulation plate.

The said insulation plate can also shield the rear of the frame.

As in the prior art, said light-transmitting plate is preferably made of glass, and is even more preferably designed as double-glazing and is further preferably provided with a reflective layer. The edges of this glass are then preferably further encased in sealing rubber in the frame, wherein the glass is preferably removably provided in the frame for cleaning and maintenance of the air-conditioning device.

The absorption plate is also preferably enclosed in the frame by means of sealing rubber in order to allow the difference in expansion of the absorption plate relative to the frame. This absorption plate is preferably also provided in the frame in such a way that it is easily removable for maintenance of the air-conditioning device.

The one or more ventilation holes are provided for ventilation of the front of the solar collector and to prevent condensation. Furthermore, a condensation trap is also provided at the bottom of the frame to collect condensation. This condensate collection can for instance be manufactured from plastic or metal and is preferably provided with a condensation outlet.

In order to, for example, heat a room with the aid of such a climate control device according to the present invention, the frame is preferably provided with an outer wall of this room so that solar radiation can be incident on the light-transmitting plate, and the air inlet is preferably lowered through the rear air outlet. the space, through the insulation plate and through this outer wall of the space. The air inlet can also be partially or completely connected to the outside air. In the latter case, the said space will be able to be heated up less quickly, but fresh air will be supplied via the air-conditioning device.

In a further specific preferred embodiment of a climate control device according to the present invention, the absorption plate in use condition of the climate control device is enclosed at its side edges in edge insulation, wherein an airflow space is available between its upper edge and the frame, and between its lower edge and the frame. provided, wherein the air inlet and the air outlet are provided one above the other, wherein an air block is provided between the insulation plate and the absorption plate, between the air inlet and the air outlet and wherein the inlet diffuser between the insulation plate and the absorption plate on the opposite side of the air inlet then the air block is provided and the outlet diffuser is provided between the insulation plate and the absorption plate on the opposite side of the air outlet than the air block.

In such a climate control device, air between the air inlet and the air outlet is forced to flow completely around the absorption plate, so that heat transfer between the absorption plate and the air flowing through occurs on both surfaces of the absorption plate. Heat transfer is thus greatly increased compared to solar collectors where only heat transfer to one surface of the absorption plate is provided.

The present invention will now be further elucidated with reference to the following detailed description of some preferred embodiments of a climate control device according to the present invention. The purpose of this description is only to provide clarifying examples and to indicate further advantages and details of these embodiments, and thus cannot in any way be interpreted as limiting the scope of the invention or the patent rights claimed in the claims.

The various air-conditioning devices (1) as shown in Figures 1 to 15 each comprise a frame which is fixed on the outside against an outer wall (15) of a room to be air-conditioned. This frame is made of metal or plastic, or any other material that is eligible for this.

Away from the outer wall (15), this frame is bounded 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. At a certain distance from the light-transmitting plate (17) an absorption plate (2) is provided which is at least partially contained in its edge insulation (16) at its edges. Between the light-transmitting plate (17) and the absorption plate (2), a sunburn effect is created in the case of solar radiation incident on the light-transmitting plate (17), whereby heat is accumulated and the absorption plate (2) can absorb maximum heat from the solar radiation.

The light-transmitting plate (17) is preferably made of glass, and is even more preferably designed as 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.

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 embodiments as shown in Figures 1 to 11 and 13, this insulation plate (6) shields the rear side of the frame. In the embodiment as shown in Figs. 12 and 14, this insulation plate (6) is mounted centrally in the frame and the frame is provided on its rear side with a second insulation plate (23), which shields the rear side of the frame.

Furthermore, the air-conditioning devices (1) from Figures 1 to 15 comprise an air inlet (3) for supplying air and an air outlet (4) for discharging air. The air inlet (3) and the air outlet (4) are provided at the rear through the frame and through the insulation plate (6) and open into the space between the insulation plate (6) and the absorption plate (2).

In these embodiments, the waves of the corrugated plate (2) as the absorption plate determine air flow channels (5) which run along the corrugated plate (2), for flowing air between the air inlet (3) and the air outlet. These 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). Secondary flows between the air flow channels (5) mutually are possible here. The respective waves of the corrugated plate (2) partially limit these air flow channels (5). As a result, these air flow channels (5) run parallel to each other and the air can flow smoothly from the air inlet (3) to the air outlet (4). These air flow channels (5) are further partially limited by the insulating plate (6), and where the air can flow between the corrugated plate (2) and the light-transmitting plate (17), they are also partially limited by this light-transmitting plate (17). Between their partial limits, the air flow channels (5) open into a common expansion space (9).

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). This inlet diffuser (7) forms an obstacle which partially shields each of the air flow channels (5) in a zone that is directed away from the absorption plate (2) and over a certain length, which in an air flow channel (5) at the level of the air inlet ( 3) is maximum and in the other air flow channels (5) proportional to the distance from the relevant air flow channel (5) to the air inlet (3) decreases with respect to the maximum length.

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). This outlet diffuser (8) forms an obstacle that partially shields each of the air flow channels (5) in a zone that is directed away from the absorption plate (2) and over a certain length, which in an air flow channel (5) at the level of the air outlet ( 3) is maximum and decreases in the other air flow channels (5) in proportion to the distance from the relevant air flow channel (5) to the air inlet (3) with respect to this maximum length.

In the illustrated embodiments, these preferred inlet diffuser (7) and outlet diffuser (8) are designed as blocks with a triangular cross-section. Another possible embodiment of the inlet diffuser (7) and the outlet diffuser (8) is, for example, as blocks with a circle segment as a section. Further, of course, numerous embodiments are conceivable for this inlet diffuser (7) and this outlet diffuser (8).

Furthermore, the air inlet (3) of a climate control device (1) according to the present invention can be provided with a pollen filter or with a dust filter.

In the embodiments of a climate control device (1) according to the present invention as shown in Figures 1 to 7, the air between the air inlet (3) and the air outlet (4) flows only between the absorption plate (2) and the insulation plate ( 6).

The air inlet (3) has a round cross-section and is provided with a fan (10) for drawing in air from the room to be air-conditioned. Furthermore, a few concentric rings (12) are arranged with a certain distance in this air inlet (3) to damp the noise of the fan (10). Three or more such rings (12) are preferably arranged for this purpose.

The air outlet (4) has a square cross-section, so that the non-return valve (11) shown can be provided. This non-return valve (11) automatically closes when the fan (10) is not working to prevent heat recoil. This way a cold fall is avoided.

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

Two fans (10) can also be installed in two stages in this air inlet (3), as in the embodiment in figure 3. One or both of these fans (10) can also be located in the room to be air-conditioned just outside the air inlet (3). These one or more fans (10) are preferably controlled with the aid of a two-stage thermostat or with the aid of two separate thermostats. For example, a first stage may be set to start the first fan at an air outlet of 23 ° C and a second stage may be set to start the second fan at an air outlet of 50 ° C so as to rapidly cool the absorption plate. The one or more fans (10) can preferably turn left or right with the aid of a changeover switch.

Between the light-transmitting plate (17) and the absorption plate (2), four ventilation holes (20) are provided in the edge insulation (16) and in the frame to prevent condensation. One or more such ventilation holes (20) are preferably provided. Furthermore, at the bottom of the space between the absorption plate (2) and the insulation plate (6), a condensation trap is provided with a condensation outlet (14) through the edge insulation and the frame.

Furthermore, the air-conditioning device (1) shown in Figs. 1 and 2 is provided with a fresh air inlet (13), which is provided with an adjustable valve (25) which can controllably open or completely close this inlet (13). This valve (25) can be opened or closed with the aid of a Servomotor or manually operated. Outside of this fresh air inlet (13), a protective cap (26) is provided to prevent, inter alia, rain water penetration.

Where this supply of fresh air is not desired, this fresh air inlet (13) can of course be omitted, such as, for example, in the embodiments in Figs. 3 to 6, to another embodiment of a climate control device (1) according to this invention.

In figures 2 and 4 it can be seen that the air inlet (3) and the air outlet (4) are provided centrally in the frame in these embodiments. These could be provided just as well, for example where boundary conditions make it difficult to place them centrally towards the edges of the frame. If this is done, the inlet diffuser (7) and / or the outlet diffuser (8) are preferably adjusted accordingly.

Preferably, as in the embodiments in Figures 3 to 6, the insulation plate (6) at the level of the inlet diffuser (7) and the outlet diffuser (8) is made thinner so that it is located further away from the absorption plate (2). then over the rest of its surface. Further preferably, this insulation plate is provided with grooves (41), each groove (41) partially shielding a respective air flow channel (5). The inlet diffuser (7) and the outlet diffuser (8) are also preferably provided with grooves (42), the grooves in the inlet diffuser (7) and the outlet diffuser (8) being deeper than in the insulation plate (6). In the embodiment shown in Figures 3 to 6, the air flow channels (5) at the level of the inlet diffuser (7) and at the level of the outlet diffuser (8) are shielded on the one hand by the absorption plate (2) and on the other hand by the inlet diffuser (7 ) or the outlet diffuser (8), wherein air cannot flow between the air flow channels (5) at the level of this inlet diffuser (7) and this outlet diffuser (8).

Still further preferably, the air flow channels (5) are provided with obstructions, which are, for example, designed as helical structures (40) with a high pitch, as in the embodiment in figures 6 and 7. These helical structures (40) can be manufactured from sheet metal or from plastic or from any other suitable material. As an alternative to the helical structures (40), as in the embodiment in Figures 4 and 5, the air flow channels (5) can be provided, for example, spread over their length with different boomerang-shaped obstructions (39).

In addition, a climate control device (1) according to the present invention as shown in Figure 3 can be provided between the air inlet (3) and the air flow channels (5) and an air inlet guide (37) for streamlined guiding of the air between the air inlet (3) ) and these air flow channels (5). A specific embodiment of such an air inlet guide (37) is shown in more detail in Figures 8a-c in different cross-sections together with arrows representing the air flow at the height of this air inlet guide (37). Analogously, an air outlet guide (38) can be provided between the air outlet (4) and the air flow channels (5). Such an air outlet conductor (38) can be constructed analogously to the air inlet conductor (37) shown in Figs. 8a-c.

Due to the simplicity of the embodiments of a climate control device (1) according to the present invention depicted here, less heat inertia occurs here than with existing climate control devices. Furthermore, fewer materials are also required to manufacture this air-conditioning device (1). Making it is also easier. Moreover, in contrast to the existing systems, instant heat can be obtained with this thermostat at 24 ° C.

Furthermore, fewer raw materials and energy are required than with existing systems to achieve the same desired climate control of the room, thanks to the greater heat transfer and thanks to the avoidance of thermal bridges.

In the embodiment of a climate control device (1) according to the present invention as shown in Figures 9 to 11, the air flows between the air inlet (3) and the air outlet (4) both between the absorption plate (2) and the insulation plate ( 6) as between the absorption plate (2) and the light-transmitting plate (17).

For this purpose, the absorption plate (2) is mounted in its state of use of the air-conditioning device (1) at its side edges in edge insulation (16), wherein an air-through-flow space (22) is provided both between its upper edge and the frame and between its lower edge and the frame. The absorption plate (2) is hereby supported in the frame with one or more supports (27).

To this end, 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.

The air block (18) is preferably provided for draining condensation water towards the underside of the space between the absorption plate (2) and the insulation plate (6), where a condensation trap with condensation outlet (14) is located. With the air block (18) shown here, condensed water is led to the sides of the air block (18) and drained there.

Both the air inlet (3) and the air outlet (4) of this air-conditioning device are provided with a fan (10). These fans can be controlled separately or together and can turn both left and right with the help of a changeover switch. Both the air inlet (3) and the air outlet (4) are provided with concentric rings to damp the noise from the fans (10). Furthermore, the air inlet (3) and the air outlet (4) are provided with grilles (12) which can control the supply and removal of air.

On the side of the light-transmitting plate (17), an inlet for fresh air (13) is provided in the frame, which inlet can be closed with a valve (25). According to the direction of rotation of the fans (10), this fresh air inlet (13) either draws in fresh air or blows out air to the outside. By blowing out air you can also lose excess heat in this way.

The absorption plate (2) has a double-walled design in such a way that it can be filled with water or coolant. This absorption plate is provided with a breather (29) at the top and a water drain (28) at the bottom. In the air-conditioning device (1) shown here, nozzles (30) are provided for maximally circulating water or a cooling liquid for distribution of this water or the cooling liquid in the absorption plate (2). With this, cold water from, for example, groundwater or a rain pit or coolant can be supplied at the bottom and discharged at the top again. For example, the air flowing through the air-conditioning device (1) can be cooled or moisture can be precipitated from the moist air. This air-conditioning device (1) can therefore also be used as air conditioning. Hot water can also be made during cooling. Even when no air is cooled, the absorption plate (2) can also serve to produce hot water. This hot water can then be used via boiler storage in a central heating system, or can serve as hot sanitary water.

Instead of designing the absorption plate (2) double-walled, an existing serrated radiator may equally well be taken as an absorption plate (2), or a tube system may be attached behind a corrugated plate as an absorption plate (2), with tubes in the waves of the corrugated plate (2) are provided.

As clearly shown in Figure 11, the absorption plate (2) is enclosed in the edge insulation (16) by means of sealing rubber (19). This sealing rubber (19) serves to compensate for the difference in expansion of the absorption plate (2) with respect to the frame.

With the embodiment of a climate control device (1) according to the present invention as shown in Figures 12 and 14, it becomes possible to obtain a complete solar control device (1) which, inter alia, for heating and cooling of spaces can be used. Quite a few solar collectors are already known that either heat air currents or water currents in order to heat a building. However, when one can extract most heat from the solar energy, namely in the summer, one needs the least heating of a building. With this climate control device (1) you can now use solar energy to the maximum to heat spaces in the winter, while in summer you can use solar energy to the maximum to cool those same spaces.

The different possibilities of this climate control device (1) are made clear by discussing the different successive layers thereof as shown in Figs. 14a-1.

The part of the air-conditioning device (1) from Figures 14a-h has a functional effect that largely corresponds to the air-conditioning device (1) from Figures 9 to 11. On this part, the part as shown in the 14h-1 added.

Figure 14a shows the light-transmitting plate (17) of this air-conditioning device (1), which is again preferably double-glazed, provided with a reflective layer.

Figures 14b to 14e show a double-walled corrugated plate as an absorption plate (2), which is internally provided with a water-permeable pipe system (31).

Figure 14b shows the first wall of the corrugated plate (2) and Figure 8d 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, in order to allow air to flow again around the corrugated plate (2). The double-walled corrugated sheet (2) is hereby supported with the aid of supports (27), which were not shown.

Figure 14c shows a first possible water-flowable pipe system (31). Figure 14d shows a variant of this tube system (31). These layers do not therefore occur simultaneously in the air-conditioning device (1), but depict alternative embodiments. As with the air-conditioning device from Figs. 9 to 11, the double-walled corrugated sheet could also be designed such that it is water-permeable. A single-walled corrugated sheet against which a water-flowable tubing system is arranged could also serve as an alternative. Other embodiments are of course conceivable. This part of the air-conditioning device (1) is provided to be used to produce hot water. With the pipe system (31) from Figure 14c, it is possible to let water run through this pipe system (31) on the basis of the thermosiphon principle. In the pipe system (31) of Figure 14d, it is necessary to install a water pump 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 tubing using a medium. The heat produced could further also be used for the purpose of using the principle of a

Stirling engine to generate electricity or can be used as domestic hot water, etc.

In figure 14c a condenser (32) is shown above the tube system (31). This is because the climate control device (1) shown here may also comprise an absorption cooling system. We will further clarify this after the other pictured components that may be part of this absorption cooling system have been discussed.

Figure 14f shows the air inlet (3), the inlet diffuser (7), the air outlet (4) and the outlet diffuser (8), with air blocking (18) in between. The dotted line also shows the air inlet (3) and the air outlet (4) of the part of the air-conditioning device (1) shown in Figures 14h-1. The air block barrier (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 (6). The condensate collection and condensation outlet (14) were not shown here, but can be seen in figure 12.

Figure 14g shows the insulation plate (6) of this climate control device (1).

Figures 14h-j show an evaporator (35) 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 141 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 Figures 14h-1. Also shown in these figures 14h-1 are the air inlet (3) and the air outlet for the part of the air-conditioning device (1) shown in figures 14a-g. In order to control the air around this whole, an air block (18) between the air inlet (3) and the air outlet (4) is provided in the gap between the corrugated plate (34) and the second insulation plate (23). Furthermore, an inlet diffuser (7) and an outlet diffuser (8) are also provided here.

In an absorption cooling system, the hot water from the tube system (31) of Figs. 14c or 14d can be used via a heat exchanger as a heat source for boiling up an absorption fluid in a generator in a known absorption cooling circuit. This was not shown. In the absorption cooling circuit, the evaporated absorption liquid then goes to the condenser (32) where it becomes liquid again. From there, the circuit continues to the evaporator (35) connected to an absorption vessel that has not been imaged. From there the circuit goes back to the generator. Since the design of such an absorption cooling circuit is known, this will not be discussed further. Optionally, solar cells can be provided on the sun-facing side of the condenser to provide the control of the absorption cooling system with electricity generated with the help of solar energy. In this way the entire climate control device (1) can again run on solar energy. There is also a possibility to add an electrical resistance to the boiler if coolness is required if insufficient solar energy is present.

A climate-control device (1) according to the present invention, which, for example, as in the embodiment from Figures 9 to 11, is also provided with means for cooling a space, is preferably provided with screening means (36) which a first state of use being in a stowed state and in a second state of use shielding the absorption plate (2), or better the means for cooling a space, from the light-transmitting plate (17). These screening means (36) can be, for example, a roller shutter or a roll-up awning, as shown in figure 13.

Just as well as these screening means (36), a second part can be provided in the air-conditioning device (1), analogous to the embodiment of figures 12 and 14, which is provided with means for cooling a space, and that is protected from the first part of the air-conditioning device (1) by means of an insulating plate (6).

By shielding the means for cooling the space from the light-transmitting plate, it is prevented that the cooling effect of the air-conditioning device (1) is counteracted by incident sunlight.

Furthermore, a climate control device (1) according to the present invention as schematically represented in Figure 15 may comprise an air-to-water heat pump (45). Cold air (44) flows via the air inlet (3) to the absorption plate (2) to absorb the heat from it, after which heated air (43) flows via the air outlet (4) to the heat pump (45). Here the energy is extracted from the warm air (43) and pumped up to a higher temperature, whereby heat is released to water. The hot water (46) obtained in this way can be used in a central heating circuit or can be used as sanitary water. Cold water (47) is supplied for heating. An electric re-heater (48) can optionally be used when less solar energy is present.

Of course, some of the above-described climate control devices (1) according to the present invention can be placed in series to obtain a new climate control device (1) according to the present invention.
