Definitions
- the invention relates to a rotor heat exchanger a rotating body, which is rotatably supported, the end face has an inflow and an outflow sector, which the Rotating body passes through during a rotation, and that from a Material matrix is formed, which consists of foils, between which flow passages axially penetrate the rotating body are formed.
- Such rotor heat exchangers are used within a heating or ventilation system arranged so that their outflow sector from the exhaust air and their inflow sector from the supply air flow becomes.
- the exhaust air flow becomes thermal energy and air humidity withdrawn, the thermal energy in the material matrix is saved and extracted from the exhaust air flow Humidity on the surfaces of the Films of the material matrix forming flow channels attaches. If the parts of the Material matrix from the outflow sector to the inflow sector advised, he takes the material matrix in the inflow sector incoming air flow heat from the material matrix and Moisture from the surfaces of the material matrix foils on. This results in the air conditioning of Clearing or the like significant savings.
- the invention has for its object the generic Develop rotor heat exchangers such that its efficiency is considerably increased.
- the Flow channels a triangular or polygonal flow cross-section exhibit. This will change to the rotor heat exchangers known from the prior art, where the flow channels have a suitable shape have rounded flow cross-section, prevents that isolate on the walls of the flow channels Form boundary layers. In the corners of the invention three or polygonal flow channels are created inevitably turbulence that the design of such insulating boundary layer that is more laminar with the Flow conditions, as in the state of the Prevail technology-trained rotor heat exchangers, usually occurs prevented.
- the invention is in rotor heat exchangers advantageously applicable, in which the radial dimension of the Flow channels between 1 mm and 3 mm.
- Aluminum has proven to be a particularly favorable material.
- the transfer of humidity from the rotor heat exchanger significantly improved.
- a further increase in Transfer capacity of the rotor heat exchanger results by coating the surfaces of the material matrix forming films with inhibited lithium chloride.
- the lithium chloride acting as an absorbent has one high affinity for water, which affects those treated in this way Surfaces very quickly forms a water film that leads to the accumulation of further moisture, which then the Material matrix in the inflow sector can be taken from the supply air flow is.
- inhibited lithium chloride has the consequence that normally very much against such salts sensitive aluminum foils permanently and without appearance severe corrosion can be coated.
- Aluminum matrices designed and coated in this way or Aluminum wheels have an air humidity transfer highest rewetting numbers and can also be used as Dryer can be used.
- lithium chloride Inhibitors As a particularly suitable one to be added to the lithium chloride Inhibitors have been chromated based Fabrics or materials with equivalent effects exposed.
- a particularly durable and against signs of corrosion permanent design of the coated with lithium chloride Aluminum matrix results when coating the Surfaces a 6 - 15 vol .-%, preferably 10 vol .-% Lithium chloride solution in water is used.
- Rotor heat exchanger 1 has one in the illustrated embodiment approximately square frame 2.
- a rotating body 3 which is designed as an aluminum wheel around a hub 4 rotatably arranged.
- a rotating motor 3 serves as a motor 5.
- An end face or flow cross-sectional area of the rotating body 3 is divided into an inflow sector 6 and an outflow sector 7.
- the inflow sector 6 formed below a horizontal beam 8, of the two opposite sides of the frame 2 connects with each other.
- the outflow sector 7 is above this horizontal support 8 is formed.
- the inflow sector 6 of the rotor heat exchanger is one Air flow 9 flows through, while the outflow sector 7 of Flows through the rotor heat exchanger 1 by an exhaust air stream 10 becomes.
- the rotating body 3 designed as an aluminum wheel consists of an aluminum matrix 12, the basic structure of which in FIG. 2 is shown, which is a sector of FIG. 1 shown rotating body 3 shows from which - in contrast to Representation in Figure 1 - the detailed structure of the rotating body 3 emerges.
- the aluminum matrix 12 consists of smooth cylindrical and folded or folded aluminum foils 13 and 14, respectively, one of which is folded or folded Aluminum foil 13 with two flat aluminum foils 14 Flow channels 15 forms the rotating body 3 and that Push the aluminum wheel through in the direction of flow.
- the surfaces of the aluminum foils 13, 14 are one capillary structure roughened, causing humidity is more transferable. Furthermore, these are the flow channels 15 forming surfaces of the aluminum foils 13, 14 treated with a lithium chloride solution which contains 10 vol .-% lithium chloride in water. As Inhibited lithium chloride is used, its inhibitor based on chromated substances are made.
- each flow channel 15 in the illustrated embodiment three tapering Corners 16, 17, 18 is due to the in these Corners 16, 17, 18 of the flow channels 15 arise Turbulence prevents a capillary narrowing of the Flow channels 15 occurs; on the walls of the channels 15 there is therefore no impairment of the heat exchange properties insulating boundary layer which at laminar flow conditions could occur. Due to the turbulence arising in the corners 16, 17, 18 thus more air particles get into immediate Contact with those through the aluminum foils 13, 14 formed walls of the flow channels 15.
