Description

Apparatus and method for conditioning ambient air

The invention relates to a method and a device for conditioning ambient air.

Such methods and apparatus have long been known and commercially available. You are for example suitable for a room with a high humidity, such. B. after a water damage, to dehumidify or to air-condition a room. Various systems are known from the prior art, by means of which the ambient air can be conditioned. These differ by the structure and by the applied working method. Thus, a distinction is made between two basic processes, the condensation process and the absorption process. Essentially, dehumidifier systems or air conditioning systems using the condensation process all use the same principle of operation, in which humid room air is drawn in by a fan and cooled down below the dew point on the working surfaces of an evaporator. Here, the excess water vapor is eliminated as condensation. In the dehumidifier system, the cooled and dried air is then passed through the hot exchange surfaces of a condenser where it is reheated and returned to the room at a specified temperature.

Alternatively, Peltier elements can also be used as cooling or condensation elements. A disadvantage of all these devices is that these, per se proven units, are subject to a relatively high energy consumption and thus no longer meet today's wishes for energy-saving facilities. Desweitern their structure is relatively expensive.

CONFIRMATION COPY Objects of the invention is to propose a method and a device which does not have at least one disadvantage of the prior art.

According to the invention, a method of the aforementioned type is proposed in which the working fluid is enclosed in a hollow body in which pressure energy can be built up. According to the invention, the working fluid, starting from a gaseous state, is rotated in such a way that forces acting on the working fluid cause a compression in the working fluid, whereby the working fluid is at least partially liquefied.

It is particularly advantageous if the hollow body is rotationally symmetrical. Since the working fluid in the hollow body is rotated in the operating state, this is particularly important for an effective working process. This also enables a smooth process flow. Also, a rotationally symmetrical design of the hollow body for an inventive device associated with the inventive device is advantageous because imbalance is avoided or at least largely avoided and increases the life of a device according to the invention described below in this way.

The compression of the working fluid thus takes place by the forces that arise during the rotation of the working fluid in the hollow body. A compressor as in a classic air conditioning or dehumidification can thus be omitted. It is also proposed that a working fluid in a hollow body in which pressure energy can be built up, starting from a gaseous state, is rotated in such a way that acts on the working fluid forces which causes an increase in pressure in the working fluid and this at least partially in the liquid state is transferred, that the working fluid is compressed by means of a switchable element higher.

Also in this method, it is for a trouble-free process flow for the reasons just described of particular advantage when the working fluid is rotated in a rotationally symmetrical hollow body in rotation.

Of course, if one speaks of a resulting force, no single force is meant. The resulting force rather serves the mathematical Design and may in particular include force or pressure components, which are composed of centrifugal forces, acting in the hollow body internal pressure and process pressures.

Therefore, it is also advantageous if the working fluid in the hollow body is acted upon by an additional applied gas pressure.

The higher a working fluid, e.g. is compressed in an air conditioning or dehumidifying system, the more thermal energy can be exchanged in the system. By the switchable element for compression, the speed can be selected smaller and / or the system can be designed for optimum efficiency. The switchable element is therefore preferably a solid element, such as a ball. By their, compared to the working fluid higher density, it compresses the working fluid by acting on them centrifugal forces, which accelerates them together with the working fluid in the hollow body, that is set in rotation. The switchable element thus has a process-enhancing effect. It may be particularly preferred that a plurality of such elements be introduced successively or simultaneously into the process. Particular preference is given to solid elements of high density, for example of steel or tungsten. If a switchable element designed as a ball is used in the method, it may occasionally be particularly preferred that the diameter of the ball is adapted to an inner diameter of tracks of the working fluid circuit described below of a device according to the invention.

Furthermore, in both methods, at least part of a thermal energy proportional to the pressure increase in connection with the compression is exchanged via a part associated with the pressure vessel with a first process fluid, in particular process air, or with an adjacent component. Furthermore, at least some of the working fluid in the subsequent process step is conducted into an evaporator and a proportional thermal energy necessary in connection with the state change to the evaporation is exchanged via a part associated with the pressure vessel with a second process fluid, in particular working air. The resulting in the process of thermal energy does not have to be delivered to a working fluid, but can also, at least partially, be delivered to adjacent components. These can also be components or devices that convert the thermal energy into other forms of energy.

Furthermore, the switchable element can be designed for further compression in such a way that it can be switched on by means of a magnetic field. Thereby, any wiring in the container, e.g. would be necessary with an electric pump, are dispensed with, so that no leaks can occur at the then necessary passages.

It is advantageous if the working fluid is caused to rotate in that the rotationally symmetrical hollow body is set in rotation. The structure is characterized very simple and different shaped rotationally symmetric hollow body can be very easily combined with a drive device. Alternatively, the working fluid in the rotationally symmetrical hollow body can be set in rotation by exerting external forces on the working fluid. In this case, the hollow body does not need to be driven. The rotational movement could be effected via a magnetically coupled to a drive stirring rod. Furthermore, the driven rotationally symmetrical hollow body may comprise spiral-shaped guide elements, through which the working medium is compressed from an inner area into an outer area and there and / or at least partially liquefied.

All methods have in common that the thermal energy exchange of the working fluid in the inner region or a first region of the hollow body with the first process fluid, process air, and in the outer region or a second region with the second process fluid, working air takes place.

To separate the process and working air corresponding air guide elements can be introduced. As a working fluid, it is possible to use any means which has gasification properties from the state of matter, preferably a refrigerant, in particular a refrigerant, from one of the following groups: R1, R4, R7, etc. For example, the refrigerant R can be used. 744 are used because it has a very large volumetric cooling capacity, the circulating refrigerant volume is therefore relatively small. It is not flammable and does not contribute to ozone depletion.

Furthermore, a device for conditioning process air is proposed. This has a hollow body with a condenser region and an evaporator region, which is filled with a working fluid, wherein the condenser and evaporator region communicate with each other. Furthermore, the device comprises a connecting element, by means of which liquid working fluid can be conducted from the condenser area into the evaporator area, so that a working fluid circuit can arise, as well as a drive.

According to the invention, the hollow body is constructed such that the working fluid in the hollow body can be set in rotation by means of a drive device driven by the drive in such a way that forces acting on the working fluid cause the working fluid to compress, as a result of which the working fluid can be liquefied at least partially in the condenser region.

When using a refrigerant, the hollow body can be filled so that this refrigerant, which is partially present in the gaseous and partially in the liquid state. If such a filled hollow body is set in rotation, the refrigerant collects by the centrifugal forces in the region of the largest diameter and is further compressed by the forces occurring.

In accordance with the explanations already given in connection with the illustration of the method according to the invention, the hollow body is most preferably constructed to be rotationally symmetrical, and the working fluid in the container can be driven by means of a drive motor driven by the drive. NEN drive device are set in rotation such that acting on the working fluid forces that causes a compression of the working fluid, whereby the working fluid is at least partially liquefied in the condenser area or provides for a further pressure increase in already liquefied working fluid. This design creates a simple cooling circuit in a hollow body, which can be set in motion that the hollow body is rotated.

In terms of a holistic energy conversion concept, it can also be advantageously provided that the device comprises an energy-converting device or is in operative connection with an energy-converting device. It is particularly preferred that the energieumwandelne unit converts the thermal energy drop of the device into electricity or back into work. The additional energy-converting unit may for example be a piezoelectric element or be formed like a turbine. Furthermore, in the condenser region, the hollow body jacket can have at least one partial surface which is thermally conductive and can be exchanged via the thermal process energy with a first process fluid, in particular working air, outside the pressure vessel designed as a hollow body. Furthermore, the hollow body jacket in the evaporator region can have at least one partial surface which is thermally conductive and can be exchanged via the thermal process energy with a second process fluid, in particular process air, outside the hollow body.

In contrast to conventional cooling or air conditioning units, this simple structure also eliminates the need for separately installed coolers in the prior art.

Structurally, it may be preferred that the hollow body is formed in one piece. Then it is the highest pressure exposable and good in mass production.

In other cases, however, it may also be preferred that the hollow body is designed in several parts. For example, if over the life of the Device dismantling, for example, provided for the replacement of the working fluid or other maintenance purposes, a multi-part design can be of particular advantage. Thus, for example, the introduction of the already described in connection with the inventive method, in particular solid-state, elements easier.

In one embodiment, the hollow body may be a rotor driven by the drive with at least one vane, wherein at least a part of the working fluid cycle runs through the at least one vane. The wing is designed such that the working air is moved through this and can exchange thermal energy with it when sweeping the wing surface.

But it is also possible to equip the rotor with a plurality of wings, which are connected to a circumferential at the wing ends annular channel, wherein the working fluid circuit passes through at least half of the existing wings. Especially at higher speeds can be avoided by this design imbalance or better balanced. In this case, the annular channel connect the cavity of the container circumferentially or divided into individual chambers, preferably always associated with a wing. Thus, optionally in two or more wings, a separate cooling circuit, or working fluid circuit, are built up as soon as the device rotates.

Furthermore, there is the possibility that the wings of the hub of the rotor spiral to the annular channel. It is also possible to attach a plurality of annular chambers, working chambers, functional chambers with functional elements, calming zones for rotating liquid mixtures to processes supporting the annular chambers. If the annular channel is divided into a plurality of annular chambers, each annular chamber is connected via a separate capillary tube to the / the evaporator region.

Winged structures are understood to mean propellers, impellers, turbine wheels and similar components. Furthermore, the spiral shape of the wing can be chosen such that in In one direction of rotation of the rotor, the vanes form the evaporator region and the annular duct form the condenser region.

The connecting element can extend inside or outside the hollow body from the condenser area to the evaporator area. It is advantageous if the connecting element is a capillary tube, through which the liquefied working fluid is conducted from the condenser region to the evaporator region.

In a further embodiment, the connecting element in the condenser region can be preceded by a pump device by means of which the working fluid can be further compressed and pumped through the connecting element to the evaporator region. The higher the compression, the better the thermal performance of the device, especially if the speed can not be so high.

To drive the pumping device can be provided that the piston of the pump comprises a magnet which is movable by means of an externally acting magnetic field from a first position to a second and thereby the piston space is reduced and the piston by means of a spring action or centrifugal forces in the first position is moved back. Due to this simple design, the pump can be easily integrated into the propeller.

As a further possible embodiment of the hollow body, it is possible to roll it up in such a spiral manner that the first and / or second process fluid can flow around the hollow body. This design can be made very easily, wherein the direction of the spiral determines the basic function of the device.

In this embodiment too, the hollow body can be profiled like a wing, so that the container causes the process fluid (s) to flow during rotation.

The cavity of each hollow body structure may be at least partially filled with a sponge-like, structurally open gas-permeable or gas- and liquid-permeable material. As a material, for example, aluminum foam or similar foams, but also sponges can be used. The agent causes the gaseous working fluid to condense and thereby the Cooling means, wherein the liquefied working fluid moves after condensation back to the outside.

It is also possible to produce the hollow body entirely from such a material, in which case a material, such as aluminum foam, should be selected, which forms a closed outer skin, which is in particular gas-tight. This can be produced, for example, by the fact that the casting mold for the aluminum foam has a correspondingly high temperature.

But it is also conceivable that the sponge-like, gas-permeable means for producing a gas-permeable skin is sealed. Depending on the expected pressure conditions, a simple heat-sealing lacquer or the like may be sufficient. In many cases, however, sealing will be necessary, for example, by a dipping process in liquid metal or by sprayed metal. The seal can also be designed in two or more parts. If the device is used for dewatering of room air, it is advantageous if the hollow body in the region of a wing has a condensate collecting device, can be collected by means of the condensed water and selectively discharged.

Furthermore, the hollow body may be coated on the outside at least in a partial area, wherein the coating may have absorbent properties.

Furthermore, the coating can be applied to a water-permeable membrane and the hollow body can, in the region of the wing, have partial regions through which water can be conducted into an intermediate layer or onto the rear-side wing surface. Furthermore, an additional cooling part may be provided, on which the moisture condenses. Furthermore, it is advantageous if the water is collected in a Wassersammei- and discharge and targeted derived.

Another way to build the device, it is the hollow body of two mounted on an axis propellers or disc-shaped chambers produce, which communicate with each other.

This can be done via the wing tips or the annular channels and the scars of the propeller with a propeller, or a disc-shaped chamber is designed substantially as a condenser and the other as an evaporator. This embodiment is particularly suitable to be installed in a wall, wherein a propeller or disk-shaped chamber on the inside of the inside air circulates and exchanges thermal energy and the other exchanges with the outside air thermal energy.

The invention furthermore relates to a hollow body for a device for conditioning process air, wherein the hollow body comprises a condenser area and evaporator area which can be filled at least partially with a working fluid and can be conducted from the condenser area into the evaporator area by the liquid working fluid, preferably via a connecting element is, are connectable such that a working fluid circuit is bildbild. The hollow body according to the invention is constructed in such a way that the working fluid in the hollow body can be set in rotation by means of a drive device driven by a drive in such a way that forces acting on the working fluid cause a compression of the working fluid, whereby the working fluid is at least partially liquefied in the condenser region. The advantages of such a hollow body can be found in the foregoing descriptions of the method according to the invention and the apparatus according to the invention for conditioning process air and can be embodied in accordance with the design forms mentioned there.

Further features of the method according to the invention and of the device according to the invention and further advantages of the invention will become apparent from the following description of preferred embodiments with reference to the drawing.

The invention will be explained in more detail with reference to drawings. In these show: Figure 1 shows the principle of operation of the method using the example of an impeller

Figure 1 shows the principle of operation of the method using the example of an impeller in section. The hollow body 1 is mounted on an axle 3, which is set in rotation by means of a drive, not shown. If the system is in rotation, the working fluid, as shown here, is thrown in a first direction of rotation by the centrifugal force into the annular channel 2 of the illustrated rotational symmetrical hollow body 1. As a result, a pressure in the working fluid, here a refrigerant, builds up. The refrigerant, which in the non-rotating system in the gaseous state 9 has a pressure of about 1 bar, is compressed by the rotation so that the pressure of the working fluid in the case of the refrigerant used is increased to about 3 to 10 bar and at least partially liquefied 8 becomes. Due to the diversity of the possible applications of the method according to the invention and the devices according to the invention, it should be pointed out that other working fluids can also be used and pressures adapted to their respective transition pressures can be generated. The thermal energy which occurs or is generated in this context and which is proportional or approximately proportional to the compression or pressure increase of the working fluid is at least partially exchanged via the annular channel 2, and / or a partial surface of the pressure vessel with the working air 7, which is heated by it. In the example given, the refrigerant is designed so that the condensation temperature at the pressure generated on a Temperature rises, which is at least over 20 ° C.

The refrigerant can be filled in, the hollow body also with a pre-pressure, so that this is partially in the liquid state after filling. In the following process step, the now-liquid working fluid via the capillary tube 10 in the evaporator region, the scar and the wing 11, shown here simplified, passed. The capillary tube 10 reduces the pressure to such an extent that the boiling temperature drops, and the coolant cools abruptly when passing into the evaporator. The proportional thermal energy necessary for evaporation in connection with the change in state is exchanged via the scar and / or the wing 11 with the process air 6, which is thereby cooled.

By cooling and condensation can be separated from the process air 6 and so the device for dehumidifying indoor air can be used.

For better heat exchange, the hollow body of a particularly thermally conductive material, for. As copper or aluminum but also from a plastic or composite material, such as a carbon fiber material exist. , To increase the work performance, it is advantageous if the hollow body has areas which are insulated, for example, by the provision of a plastic coating.

FIG. 2 shows a plan view of an impeller 2. Also, this drawing is intended to illustrate only the principle of the process. As in Figure 1, not all details are shown here, which may still be necessary for the function.

Further details and possible embodiments are shown in the following figures.

Thus, FIGS. 3 and 4 show ways in which the pressure in the cooling liquid can be further increased. The solutions are in relation to that Impeller shown in Figures 1 and 2. This functionality can also be incorporated into other or one of the following versions.

Both options, the pump 12 but also the flap 18 can be used to increase the pressure in the coolant clocked on. The pump 12 as well as the flap 18 are actuated from the outside by means of a magnet 14. The number of attached to the rotationally symmetrical hollow body 1 magnets 14 determines the clock per revolution.

The pump 12 is made of a magnetic material by means of the magnet 14 movable piston 13 which is pressed by means of the spring 16 in a first position, suction. As soon as the pump is rotated past a magnet, the magnetic forces act on the piston and this is entrained by the latter and pumps the coolant 8 against the check valve 16 in the capillary tube 10, whereby the refrigerant is further compressed. It is not shown that the heat generated by the pump 12 is dissipated by means of cooling fins on the annular body 2. The suction takes place via the intake 17, which should preferably suck on the outermost point of the hollow body or annular channel. For this purpose, it is also possible to provide recesses in the hollow body 1 in which the coolant collects due to the centrifugal forces. The flap 18 generated by the inertia a sudden pressure increase in the coolant 8, when this is placed by means of the outer magnet.

FIG. 5 shows an embodiment of the hollow body 1. If the hollow body 1, or propeller, rotated in this embodiment in the clockwise direction, the cooling liquid is liquefied in the annular channel 2. The spiral vanes 11 in this case represent the evaporator region 22 and come into contact with the process air 6, which is thereby cooled and / or dehydrated.

The condenser region 21 is in this case the annular channel 2, here is exchanged via the wall heat with the working air 7, whereby the working air is heated. The waste heat of the condensation process caused by the change in state of the working fluid within a rotating hollow body is created, so it is delivered to the working air, in general so in the room existing ambient air. The higher the speed, the greater the accelerations, whereby more heat is automatically supplied to the working air or must be dissipated from the working air. Depending on the air flow, it is conceivable to direct the working air 7 in such a way that it becomes the process air 6. It is exploited that warm working air again can store a higher amount of moisture. For example, if accelerated warm working air bypasses moist building substances, it absorbs more moisture from the building materials more quickly at a higher temperature and thus promotes the effectiveness of the drying process. In the condensation process already described, a particularly high amount of condensate to be separated is then released.

The capillary tubes 10 can, as shown here, extend within the condenser region 21 from the condenser region 21 to the evaporator region 22 within, but also outside, the wing 1.

The air streams, so the process air as well as the working air are as shown in Figure 1 in all versions by suitable air ducts separated from each other so that they can not mix directly.

However, it is also conceivable, in particular when using the propeller in the dehumidification of room air, to heat the process air 6 after or before cooling and dewatering by means of the condenser, so as to recover the heat or increase the effectiveness of the drainage.

Furthermore, it is conceivable to use the condensate for cooling the condenser. It is also conceivable to use the waste heat of the drive motor. FIG. 6 shows, by way of example, an embodiment in the form of a screw. By this embodiment, the pressure in the coolant is particularly increased. The hollow body 1 of the screw is rolled up in a spiral in such a way that the first and / or second process fluid (6, 7) can flow around the hollow body (1).

As in all previous versions, the subsection of this is also with this the process air 6 and / or the working air 7 comes in contact at least partially profiled like a wing, so that the container during rotation, the process fluid 6 and / or the working air 7 in flow.

It is also possible to connect a plurality of the previously described propellers 24 one behind the other, wherein the profile of the process air 6 between the propellers 24 can be varied.

The description of the coupling of the engine has been omitted here, as the skilled person many possibilities are well known from the prior art. The embodiment in FIGS. 7a, 7b and 8 differs significantly from the previous ones. In essence, there is a hollow body 1, which is formed by two propellers 24. The two propellers 24, or their cavities are interconnected. Between the two propellers 24 is a partition, here a wall 28 which is formed in the region of the propeller 24 by a filling material. Thus, this device can be easily mounted from one side of the wall 28. The propellers 24 may be constructed substantially as described above and shown in FIG. 5 or 6.

It is essential that the propeller 24 are constructed mirror-inverted on both sides of the wall 28 and the filling material 25, see Fig. 8, that is, the flights 11 of the propeller are substantially shaped so that the process air 6 and the working air 7, depending on Direction of rotation of the axis 3, is moved from outside to inside or from inside to outside. Furthermore, the propellers are constructed such that one operates as a cooling wheel and the other as a heating wheel. In other words, this means that the compression takes place in the ring area in one propeller 24 and in the hub area in the other propeller.

In Figure 7a, the process air propeller operates as a cooling wheel, e.g. to cool the room air and / or to dehumidify, and the working air propeller as a heating, z. B. dissipate the heat over the outside air.

If the device is rotated, creates a coolant circuit between see the two propellers 24, wherein the left shown in the sketch Propeller 24 is designed as an evaporator and the right as a condenser.

The connection between the evaporator propeller and the condenser propeller in this variant is the capillary tube 10 positioned near the axis 3. The connection of the annular channels can be a capillary tube or a simple connecting tube 29.

During rotation, the working fluid is precompressed in the annular channel 2 of the cooling wheel and passed from there via the connection 29 to the heating wheel and there further compressed by the reverse compression process, from annular channel towards the scar and liquefied. In Fig. 7b, the case is shown when the device is rotated in the opposite direction. Then the evaporator wheel is the working air propeller and the compression wheel is the process air propeller. Since only the direction of rotation is changed, the air flows through the propeller are exactly reversed as shown in Fig. 7a. The motor can be arranged in the intermediate layer as shown in both figures and the torque support can be effected via the axle which is fastened to the wall by means of fastening means, not shown. The intermediate layer has an annular channel, not shown for the connection 29, so that the hollow body 1 can rotate freely. Also not shown are possible construction variants of a wing and the Kondeswasserableitung from the wing.

To regulate the power various devices and methods can be used. Thus, the wings can be designed to be adjustable, wherein the skilled person various types of adjustment from the StdT are known, such as a temperature-controlled adjustment. For this purpose, z. B. bimetallic devices or so-called intelligent metal-plastic compounds. For temperature measurement, a color indicator or wireless temperature sensor can also be used.

The speed of the example designed as a propeller cavity can but continue to be made depending on ram pressure, differential pressure, flow, humidity, temperature and / or the dew point of the working fluid or the process air.

It can also be provided to regulate the fluid pressure and / or the fluid pressure in the capillary tube. It is also possible to provide bypasses from capillary tube to capillary tube, which compensate for pressure equalization between partial circuits or a plurality of system wheels. In addition, pressure equalization chambers could compensate for thermal influences in order to increase the efficiency.
