Description
Rotating Heat Exchanger and Ventilation System Herewith The invention relates to a rotating heat exchanger with a housing in which two canals, which are separated from one another, are configured for each conducting an air flow and furthermore comprising a, for example, drum-like heat-exchanger element that is a rotatably provided in the housing in such a manner that the heat-exchanger element is in contact with each of the two canals, wherein the heat-exchanger element is associated with a drive device for generating a rotation of the heat-exchanger elernent.
Rotating heat exchangers of the previously mentioned type are heat exchangers in which a primary-media volume flow and a secondary-media volume flow reciprocally flow through the same heat-exchanger surfaces, thereby transmitting heat energy or cold energy to the surfaces or taking it up therefrom. In this manner, a transfer of heat energy occurs, for example, from the secondary-media volume flow formed by the outgoing air from a building section to, for example, a primary-media volume flow formed from the fresh air in a building section. The reciprocal flowing through is effected by the reciprocal rotation of the heat exchanger or bys parts of the heat exchanger through the respective primary or secondary air flow.
Document EP 1 486 747 A2 discloses a rotating heat exchanger of the previously mentioned type in which the rotation of the heat-exchanger element is generated by an electromotive rotation drive. The installation space required for this motor as well as the costs of the motor in the production and in the operation of the heat exchanger are regarded as disadvantageous in many cases.

Document EP 1 486 747 A2 discloses a rotating heat exchanger of the previously mentioned type in which the rotation of the heat-exchanger element is generated by an electromotive rotation drive. The installation space required for this motor as well as the costs of the motor in the production and in the operation of the heat exchanger are regarded as disadvantageous in many cases.
In document EP 1 029 202 B1, a rotating heat exchanger is proposed in which a swirled airflow, which is the direct downstream of an axial fan, is conducted through a heat-exchanger drum that is caused to rotate owing to frictional forces between the air flow and the drum. This manner of construction assumes not only that the fan is arranged in direct proximity to the heat exchanger, which is frequently impossible owing to the installation situation, but also additionally the drive is regarded as disadvantageous owing to the very minimal transfer of the swirl of the airflow to the heat-exchanger element.
The problem addressed by the present invention is, in contrast, to provide a rotating heat exchanger of the type previously mentioned that is compact in construction as well as cost-effective to manufacture and operate and that moreover makes possible at the same time a particularly effective rotation drive of the heat-exchanger element.
This problem is substantially solved according to the invention in that the drive device comprises a turbo machine, in particular configured as an attachment roller, and means for transmitting a moment of torque from the turbo machine to the heat-exchanger element. In the rotating heat exchanger according to the invention, the flow energy intrinsic in the primary and/or the secondary air flow is accordingly used in part in order to generate the rotation movement of the heat-exchanger element. A turbo machine, in the meaning of the present invention, is a device that uses an axial, radial and/or tangential air stream in order to generate a rotation by means of blades, paddles or the like. According to a particularly preferred embodiment of the invention, an attachment roller is arranged on the one front face of the housing coaxial to the axis of rotation of the heat-exchanger element, said attachment roller being flowed against by one of the two air streams in order to generate the rotation of the heat-exchanger element.

This problem is substantially solved according to the invention in that the drive device comprises a turbo machine, in particular configured as an attachment roller, and means for transmitting a moment of torque from the turbo machine to the heat-exchanger element. In the rotating heat exchanger according to the invention, the flow energy intrinsic in the primary and/or the secondary air flow is accordingly used in part in order to generate the rotation movement of the heat-exchanger element. A turbo machine, in the meaning of the present invention, is a device that uses an axial, radial and/or tangential air stream in order to generate a rotation by means of blades, paddles or the like. According to a particularly preferred embodiment of the invention, an attachment roller is arranged on the one front face of the housing coaxial to the axis of rotation of the heat-exchanger element, said attachment roller being flowed against by one of the two air streams in order to generate the rotation of the heat-exchanger element.
If the turbo machine is configured as a repeller, the rotation of the heat-exchanger element can be generated by an axial air stream from at least one of the two air flows flowing against the repeller. This can, for example, be effected in that an attachment roller, which has propeller blades that are frontally flowed against, is provided on or in the housing, wherein the moment of torque is generated to drive the heat-exchanger element by one of the two air flows flowing through the attachment roller.
In order to not negate this moment of torque by the corresponding effect of the counterflowing air flow, it is preferred if the canals are arranged relative to the turbo machine in such a manner that only one of the two air flows acts on the turbo machine while the other of the two air flows is conducted away from the turbo machine and/or is partitioned therefrom. In this manner, one of the two air flows can be conducted substantially axially and without deflection through the housing and drive the turbo machine, while the other air flow is deflected by 90 within the housing in order to no longer come into contact with the turbo machine.
According to yet a further embodiment of the invention, the turbo machine is a turbine that is driven by at least one of the two air flows by radial and/or tangential air currents. The attachment roller can, for example, be configured as a turbine blade that is radially flowed against, wherein the air flow that drives the turbo machine can be laterally directed into the housing of the heat exchanger.
In many cases, it is preferred if the heat exchanger is operated on the countercurrent principle, that is to say if the air flows of the housing flow therethrough in opposite directions at least in sections.
In order to prevent a too rapid rotation of the heat-exchanger element, a braking device, in particular a mechanical one, is additionally provided according to an advantageous embodiment of the invention, said braking device braking in a defined manner the rotation of the heat-exchanger element and/or stopping it at pre-determined time intervals. In this manner, an intermittent rotation of the heat-exchanger element can be generated. It is especially preferred if the heat-exchanger element carries out a rotation of 180 in a timed manner by means of a mechanical device or the braking device.
The heat exchanger according to the invention is preferably configured in such a manner that the heat-exchanger element is mounted in its rotational axis in such a manner that the rotation movement is subjected to the least amount of resistance possible. In order to also generate the least amount of frictional resistance possible by the required sealing of the air flows against one another, it is preferred if the canals are sealed from one another by means of at least one front-face sealing roller. Sealing rollers characterise themselves by a comparably low friction resistance owing to their rotational movement that is synchronous with the heat-exchanger element.
The invention furthermore relates to a ventilation system having at least one rotating heat exchanger of the above-mentioned type, wherein at least one fan is provided that conducts at least one of the two air flows through one of the canals of the heat exchanger. The fan delivers the flow energy required for the rotation drive of the heat-exchanger element.
The recuperative properties of the rotating heat exchanger are dependent on, in addition to size, structural shape, surface structure, and the heat-exchanger element material used, the rotational speed as well. In order to optimise the self-rotating heat exchanger according to the invention, preferably the number, the shape, the size, and the arrangement of the blades in the attachment roller or in the turbo machine are configured and designed) in such a manner that they correspond as much as possible to the rotation speed, which corresponds to the respective air flow of the desired or optimal rotation speed.
In order to not negate this moment of torque by the corresponding effect of the counterflowing air flow, it is preferred if the canals are arranged relative to the turbo machine in such a manner that only one of the two air flows acts on the turbo machine while the other of the two air flows is conducted away from the turbo machine and/or is partitioned therefrom. In this manner, one of the two air flows can be conducted substantially axially and without deflection through the housing and drive the turbo machine, while the other air flow is deflected by 90 within the housing in order to no longer come into contact with the turbo machine.
According to yet a further embodiment of the invention, the turbo machine is a turbine that is driven by at least one of the two air flows by radial and/or tangential air currents. The attachment roller can, for example, be configured as a turbine blade that is radially flowed against, wherein the air flow that drives the turbo machine can be laterally directed into the housing of the heat exchanger.
In many cases, it is preferred if the heat exchanger is operated on the countercurrent principle, that is to say if the air flows of the housing flow therethrough in opposite directions at least in sections.
In order to prevent a too rapid rotation of the heat-exchanger element, a braking device, in particular a mechanical one, is additionally provided according to an advantageous embodiment of the invention, said braking device braking in a defined manner the rotation of the heat-exchanger element and/or stopping it at pre-determined time intervals. In this manner, an intermittent rotation of the heat-exchanger element can be generated. It is especially preferred if the heat-exchanger element carries out a rotation of 180 in a timed manner by means of a mechanical device or the braking device.
The heat exchanger according to the invention is preferably configured in such a manner that the heat-exchanger element is mounted in its rotational axis in such a manner that the rotation movement is subjected to the least amount of resistance possible. In order to also generate the least amount of frictional resistance possible by the required sealing of the air flows against one another, it is preferred if the canals are sealed from one another by means of at least one front-face sealing roller. Sealing rollers characterise themselves by a comparably low friction resistance owing to their rotational movement that is synchronous with the heat-exchanger element.
The invention furthermore relates to a ventilation system having at least one rotating heat exchanger of the above-mentioned type, wherein at least one fan is provided that conducts at least one of the two air flows through one of the canals of the heat exchanger. The fan delivers the flow energy required for the rotation drive of the heat-exchanger element.
The recuperative properties of the rotating heat exchanger are dependent on, in addition to size, structural shape, surface structure, and the heat-exchanger element material used, the rotational speed as well. In order to optimise the self-rotating heat exchanger according to the invention, preferably the number, the shape, the size, and the arrangement of the blades in the attachment roller or in the turbo machine are configured and designed) in such a manner that they correspond as much as possible to the rotation speed, which corresponds to the respective air flow of the desired or optimal rotation speed.
The rotation speed of the heat-exchanger element can thereby be adjusted in that the rotation speed is effected by means of a suitable sensor and is used by, for example, a digital, electronic control unit for the optimisation of the heat-energy transfer or recovery process in that the rotation speed of the heat-exchanger element is coordinated to the air flows by finely controlling the current speed of the air flows. The heat exchanger is for this purpose preferably associated with at least one sensor for detecting the rotation speed of the heat-exchanger element, said sensor being connected to a system for controlling or regulating the fan.
In this manner, the energy content, the temperatures, the quality, the humidity or the consistency, as well as the current speed of the air flows can be adjusted in a defined manner.
This embodiment of the ventilation system according to the invention makes possible not only an optimisation of the pure thermal heat-energy transfer or recovery, but also makes it possible to optimise dehumidification or rehumidification in a rotating air heat exchanger.
The ventilation system according to the invention can additionally comprise at least one sensor for detecting the temperature and/or the humidity of the heat-exchanger element and/or of at least one of the two air flows, wherein the sensor is connected to a device for controlling or regulating the fan.
The control device can additionally be used in order to overcome a potentially higher starting resistance of the heat-exchanger element in that a momentary higher air flow is generated through the fan in a pulsed manner. The clock frequency or the control of the rotation by 1800 of the heat-exchanger element can also be effected by means of the, for example, digital electronic control of the ventilation system.
In this manner, the energy content, the temperatures, the quality, the humidity or the consistency, as well as the current speed of the air flows can be adjusted in a defined manner.
This embodiment of the ventilation system according to the invention makes possible not only an optimisation of the pure thermal heat-energy transfer or recovery, but also makes it possible to optimise dehumidification or rehumidification in a rotating air heat exchanger.
The ventilation system according to the invention can additionally comprise at least one sensor for detecting the temperature and/or the humidity of the heat-exchanger element and/or of at least one of the two air flows, wherein the sensor is connected to a device for controlling or regulating the fan.

The canals 5a, 5b, for example, are a component of a ventilation system, which is not more closely shown in the figures, wherein outgoing air from a building flows through the canal 5a, and external air is introduced into the building by means of the canal 5b in the embodiment shown. As can be seen in the representation of figure 2, the first canal 5a for the outgoing air runs between an inlet opening 6a and an outlet opening 7a substantially parallel to the canal 5b. A deflection section 8 is connected to the outlet 7a of the first canal 5a in such a manner that the outgoing-air current in figure 1 can leave the housing 2 from above. In contrast, the external-air flow from an inlet 6b runs to an outlet 7b of the second canal 5b in a substantially axial direction without deflection. The canals 5a and 5b are separated from one another by a central web 9.
