Definitions
- the invention relates to a rotary heat exchanger with a housing in which two separate channels for the passage of each air flow are formed, and with an example.
- Drum-like heat exchanger element which is rotatably provided in the housing such that the heat exchanger element with each of the two channels in Contact is, wherein the heat exchanger element is associated with a drive means for generating a rotation of the heat exchanger element.
- Rotary heat exchangers of the type mentioned in the introduction are heat exchangers in which a primary medium volumetric flow and a secondary medium volumetric flow alternately flow through the same heat exchanger surfaces and thereby transfer heat or refrigeration energy to these surfaces or absorb them from these surfaces.
- a transfer of heat energy takes place, for example, from the secondary media volume flow formed by the exhaust air from a building part to the primary media volume flow formed, for example, by the supply air into a building part.
- the mutual flow is effected by the mutual rotation of the heat exchanger or of parts of the heat exchanger by respectively the primary and secondary air flow.
- EP 1 029 202 B1 proposes a rotary heat exchanger in which a swirling air flow, which is the direct outflow of an axial fan, is passed through a heat exchanger drum and causes it to rotate due to frictional forces between the air flow and the drum.
- This design not only requires that the fan is placed in the immediate vicinity of the heat exchanger, which is often not possible due to the installation situation, but it also the drive due to the very small transmission of the swirl of the air flow to the heat exchanger element is considered disadvantageous ,
- Object of the present invention in contrast, to propose a rotating heat exchanger of the type mentioned, which is cost-effective in the production and operation in a compact design and at the same time allows a particularly effective rotary drive of the heat exchanger element.
- the drive device has a turbomachine, in particular designed as an attachment roller, and means for transmitting a torque from the flow machine to the heat exchanger element.
- a turbomachine in particular designed as an attachment roller, and means for transmitting a torque from the flow machine to the heat exchanger element.
- the flow energy inherent in the primary and / or secondary air flow is used in part to produce the rotational movement of the heat exchanger element.
- a turbomachine is a device which uses an axial, radial and / or tangential air flow in order to generate a rotation by means of vanes, blades or the like.
- an attachment roller is arranged coaxially with the axis of rotation of the heat exchanger element on the one end face of the housing, which is flown to generate the rotation of the heat exchanger element of one of the two air streams.
- the rotation of the heat exchanger element can be generated by flowing the repeller with an axial air flow of at least one of the two air streams. This can be done, for example, by providing an attachment roller with front-flowed propeller blades on or in the housing, wherein the torque for driving the heat exchanger element is generated by the flow through the attachment roller with one of the two air streams.
- the channels are arranged relative to the turbomachine such that only one of the two air streams acts on the turbomachine, while the other of the two air streams of the Turbomachine is routed away and / or foreclosed against this.
- one of the two air streams can be passed substantially axially and without deflection by the housing and drive the turbomachine, while the other air flow is deflected within the housing by 90 °, so as not to come into contact with the turbomachine.
- the turbomachine is a turbine driven by at least one of the two air streams through radial and / or tangential air flow.
- the attachment roller can be formed as a turbine blade, which, for example, has a radial flow, wherein the airflow that drives the turbomachine can be introduced laterally into the housing of the heat exchanger.
- the heat exchanger is operated in the countercurrent principle, ie if the air streams flow through the housing at least in sections in the opposite direction.
- a, in particular mechanical, braking device is provided, which decelerates the rotation of the heat exchanger element defined and / or stops at predetermined time intervals. In this way, an intermittent rotation of the heat exchanger element can be generated. It is particularly preferred if the heat exchanger element clocked by a mechanical device or the braking device each performs a rotation of 180 °.
- the heat exchanger according to the invention is preferably designed such that the heat exchanger element is mounted in its axis of rotation so that the rotational movement is opposed as little resistance as possible.
- the channels are sealed against one another by means of at least one front-side sealing roller. Sealing rolls are distinguished by a comparatively low frictional resistance due to their synchronous with the heat exchanger element rotational movement.
- the invention further relates to a ventilation system with at least one rotating heat exchanger of the above type, wherein at least one fan is provided, which promotes at least one of the two air streams through one of the channels of the heat exchanger.
- the fan supplies the time required for the rotational drive of the heat exchanger element flow energy.
- recuperative properties of the rotating heat exchanger are in addition to size, design, surface structure and material used of the heat exchanger element also dependent on the rotational speed.
- inventive self-rotating heat exchanger are preferably the number, shape, size and arrangement of Wing in the attachment roller or the turbomachine designed and designed so that the corresponding to the respective air flow rotational speed of the desired or optimal rotational speed corresponds as possible.
- the rotational speed of the heat exchanger element can be adjusted by determining the rotational speed by means of a suitable sensor and by an example digital electronic controller for optimizing the furnished energieübertragungs- or - back trenchungsreaes by the rotational speed of the heat exchanger element is tuned by fine control of the flow velocity of the air streams.
- the heat exchanger is preferably associated with at least one sensor for detecting the rotational speed of the heat exchanger element, which is connected to a device for controlling or regulating the fan. In this way, the energy content, the temperatures, the nature, the humidity or the consistency, as well as the flow rate of the air streams defined set.
- This embodiment of the ventilation system according to the invention not only allows an optimization of the purely thermal planteenergieübertragung- or -recovering, but also allows optimization of dehumidification or rewetting in a rotating air heat exchanger.
- the ventilation system according to the invention may additionally comprise at least one sensor for detecting the temperature and / or humidity of the heat exchanger element and / or at least one of the two air flows, wherein the sensor is connected to a device for controlling or regulating the fan.
- the controller can also be used to overcome a possibly higher starting resistance of the heat exchanger element by pulse-like a momentarily higher air flow is generated by the fan.
- the clock frequency or the control of the rotation by 180 ° of the heat exchanger element can also take place via the eg digital electronic control of the ventilation system.
- FIG. 1 is a perspective view of a heat exchanger according to the invention.
- FIG. 2 shows a longitudinal section through the heat exchanger according to FIG. 1.
- the heat exchanger 1 shown in the figures essentially consists of a box-like housing 2, a heat exchanger element 3 arranged therein and a turbomachine 4.
