Aufgabenstellungtask
Die vorliegende Erfindung hat sich die Aufgabe gestellt wirkungsvolle Wärmetauscher zu schaffen, die sowohl die Wärme der Sonneneinstrahlung auf einen flüssigen Wärmeträger übertragen können, als auch die in der Luft enthaltene Wärme. Dabei soll der Wärmetauscher preiswert zu fertigen sein. Der Wärmetauscher soll für Aufstellung (Montage) an für Luft- und Sonneneinstrahlung frei zugänglichen Orten geeignet sein wie z. B. in Gärten, auf Hausdächern, auf dem First von Dächern oder an Hausecken.The The present invention has set itself the task of effective Heat exchangers create both the heat the solar radiation transferred to a liquid heat carrier as well as the heat contained in the air. In this case, the heat exchanger should be inexpensive to manufacture. The heat exchanger should be used for installation (assembly) at freely accessible for air and solar radiation Be suitable places such. In gardens, on rooftops, on the ridge of roofs or on house corners.
Lösungsolution
Gelöst wird diese Aufgabe mit den im kennzeichnenden Teil des Anspruchs 1, bzw. der Ansprüche 2 und 3 angegebenen Merkmalen. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Solved This object is achieved with the in the characterizing part of claim 1, or the claims 2 and 3 specified characteristics. Advantageous developments The invention are specified in the subclaims.
Effektive Wärmetauscher lassen sich durch zu Spiralen gewickelten Kunststoffrohren darstellen, wenn diese lang genug sind, d. h. insgesamt eine große Oberfläche darstellen. Der Wärmeträger, der in den Rohren umgepumpt wird, muss langsam fließen, damit genügend Zeit für die Übertragung von Wärme durch den Kunststoff, z. B. schwarzes PE100 bleibt. Zur Lösung der oben beschriebenen Aufgabe wurden neuartige Wärmetauscher als Kombiwärmetauscher für die Übertragung sowohl der Wärme der Sonneneinstrahlung als auch der in der Luft enthaltenen Wärme entwickelt. Sie bestehen aus mehreren aus Kunststoffrohren ineinandergewickelten Spiralen. Erfindungsgemäß werden aus den Spiralen ungefähr gleich lange Stränge gebildet, die sich besonders gut für Parallelschaltung zu einer Pumpe eignen. Zu- und Ablauf des Wärmetauschers werden an einem Ende angeordnet. Wird der Wärmetauscher z. B. aus 4 ineinandergewickelten Spiralen mit nach innen kleiner werdenden Durchmesser gebildet, so wird der Wärmeträger durch die äußerste Spirale hin- und durch die innere Spirale zurückgeführt. Der zweite Hin- und Rücklauf erfolgt durch die dazwischen liegenden Spiralen. Der Wärmetauscher nimmt Wärme sowohl aus der durchströmenden Luft, aus Regen, als auch mit seiner dunklen großen Oberfläche aus der Sonneneinstrahlung auf. Solche Wärmetauscher arbeiten besonders wirkungsvoll, wenn sie auf dem First eines Daches, über der Dachfläche, an Häuserecken oder frei stehend im Garten angebracht werden. Dabei ist zum Wickel ein Abstand zu wählen, der den Wärmetäuscher oberhalb einer Schneedecke hält. Gerade in der Übergangszeit zwischen Winter, Herbst und Frühling also in der längsten Zeit der Heizperiode, lassen sich mit den beschriebenen Wärmetauschern günstige Temperaturen für eine Wärmepumpe erzielen. Zweckmäßig werden die Kombiwärmetauscher mit Erdwärmekörben gekoppelt. An Frosttagen schaltet die Steuerung der Wärmepumpe von Kombiwärmetauschern auf Erdwärmekörbe um.effective Heat exchangers can be wound by spirals Plastic pipes, if they are long enough, d. H. all in all to represent a large surface. The heat carrier, which is pumped in the pipes, must flow slowly, With enough time for the transfer of heat through the plastic, z. B. black PE100 remains. To solve the problem described above were novel Heat exchanger as combi heat exchanger for the transmission of both the heat of sunlight as well as the heat contained in the air. They consist of several plastic tubes wound together Spirals. According to the invention from the spirals approximately equal long strands formed, which is particularly suitable for parallel connection to a pump. Inlet and outlet of the heat exchanger are at one end arranged. If the heat exchanger z. B. from 4 intertwined Spirals formed with decreasing in diameter, so the heat transfer medium through the outermost Spiral back and forth through the inner spiral. The second round trip takes place through the between lying spirals. The heat exchanger absorbs heat as well from the flowing air, from rain, as well as with his dark big surface from the sunlight on. Such heat exchangers work particularly effectively when on the ridge of a roof, above the roof, be attached to houses corners or free standing in the garden. It is to choose a distance to the winding, the heat exchanger holding above a blanket of snow. Especially in the transitional period between winter, autumn and spring so in the longest Time of the heating period, can be with the described heat exchangers favorable temperatures for a heat pump achieve. The combi heat exchangers are useful coupled with geothermal baskets. On frosty days switches the control of the heat pump of combi heat exchangers on geothermal baskets.
Der Wirkungsgrad für die Aufnahme von Wärme aus der Luft lässt sich für den erfindungsgemäßen Wärmetauscher durch eine Zwangsbelüftung steigern. Dazu wird der Wärmetauscher an einem Ende mit einer Platte abgeschlossen und an der gegenüberliegenden Seite ein Lüfter montiert.Of the Efficiency for absorbing heat from the Air can be for the inventive Increase heat exchanger by forced ventilation. For this, the heat exchanger is at one end with a plate completed and on the opposite side a fan assembled.
Für eine gleichmäßige Umflutung der Windungen des Wärmetauschers mit Luft wird der Abstand zwischen den Windungen vom Lüfter ausgehend, von klein auf größer geändert. Ist der Kombiwärmetauscher z. B. auf dem First eines Hauses montiert, kann auch die durch Sonneneinstrahlung von der Dachfläche aufsteigende warme Luft durch ihn genutzt werden. Vorteilhaft wird über dem Kombiwärmetauscher eine lichtdurchlässige Abdeckung angebracht, die bis über die Dachfläche reicht. Die Abdeckung wird auch gewellt ausgeführt, um das Sonnenlicht bei unterschiedlichen Einstrahlwinkeln optimal zu nutzen. Bei Saugbetrieb des Lüfters saugt dieser die warme Luft des Daches über die Windungen des Wärmetauschers. Wird ein solcher Wärmetauscher im Sommer ohne Lüfter zur Erwärmung von Brauchwasser genutzt, kann es unter der Abdeckung zu gefährlichem Wärmestau kommen. Um das auszuschliessen, wird die Platte am Ende mit temperaturmechanisch (Wachskolben, Bimetall usw) betriebenen Klappen ausgerüstet. Sie öffnen bei zu hoher Temperatur und bewirken durch Schornsteineffekt den Fluß kühlender Luft für den Wärmetauscher.For a uniform flooding of the windings of the heat exchanger with air, the distance between turns from the fan is changed from small to larger. If the combi heat exchanger z. B. mounted on the ridge of a house, and the rising from sunlight from the roof surface warm air can be used by him. Advantageously, a translucent cover is placed over the combi heat exchanger, which extends over the roof surface. The cover is also waved to optimally use sunlight at different angles of incidence. With suction operation of the fan sucks this the warm air of the roof over the coils of the heat exchanger. If such a heat exchanger is used in the summer without fan for heating domestic hot water, it can lead to dangerous heat accumulation under the cover. To exclude this, the plate is equipped at the end with temperature-mechanically operated (wax piston, bimetal, etc.) operated flaps. They open at too high a temperature and cause by chimney effect the flow of cooling air for the heat exchanger.
Für eine stabile Ausführung des Wärmetauschers lassen sich z. B. die Windungen zweier Spiralen in Löcher von Haltestreifen klippsen. Die Haltestreifen definieren den Abstand der beiden Spiralen voneinander und definieren die Steigung der Windungen. Sie sind auf Schienen montiert, die an kreuzförmigen Träger gehalten werden. Nach dem zwei Wicklungen gewickelt wurden, können z. B. weitere Schienen mit Haltestreifen auf den Armen der kreuzförmigen Träger montiert werden. Dann lassen sich z. B. in gleicher Weise wie beschrieben zwei weitere darüber liegende Wicklungen fertigen. An den Armen der kreuzförmigen Träger sind Halterungen gut zu befestigen für die Montage des Kombiwärmetauschers z. B. auf Dachfirsten, auf Dachflächen oder an Häuserecken.For Leave a stable version of the heat exchanger z. B. the turns of two spirals in holes of Clip retaining strips. The retaining strips define the distance of the two spirals from each other and define the slope of the Turns. They are mounted on rails that are at cross-shaped Carrier be held. After the two windings wrapped were, z. B. more rails with retaining strips mounted on the arms of the cross-shaped support become. Then let z. B. in the same way as described make two more overlying windings. To the Arms of the cross-shaped beams are brackets good for mounting the combi heat exchanger z. B. on roof ridges, on roofs or at the corners of houses.
