Ergänzung zur Beschreibung der Patentanmeldung "AbgekühlteSupplement to the description of the patent application "Abgekühlte
Latentwärmespeicher für Raumheizung und -abkühlung mittels direkter oder vom Wasser gebundener, indirekter Sonnen energie;' Akt. Z. P 310# 443.0 Weil, gemäss meiner Kalkulationen, der Arbeitsdruck der zahlreichen, untereinander identischen Kompressoren in der früher beschriebenen Konstruktion nur in Grössenordnung von 2 - 3 atü ist, können die kleinen, zwar billigen Motor-Verdichter-vinheiten mit noch einfacheren Kompressoren ersetzt werden.Latent heat storage for space heating and cooling by means of direct or indirect solar energy bound by water; ' Current Z. P 310 # 443.0 Because, according to my calculations, the work pressure of the numerous, identical to each other Compressors in the design described earlier are only in the order of magnitude of 2 - 3 atm, the small, cheap motor-compressor units can with even simpler compressors can be replaced.
Fig. 1 zeigt ein Beispiel von so einem Komponentenbau. Die Verdichter können aus zahlreichen, balgenähnlichen Komponenten gebaut werden, jeder bestehend aus zwei elastischen, gegen schädliche chemische Wirkungen und mechanische bnut zung aushaltenden, von einer oder mehreren Verstärkungsscheiben (1) gestützten Membranen (2), die in ihrer Peripherie hermetisch zusammengefügt sind und deren Mitte während des Saugtaktes gegenseitig voneinander entfernt und während des Arbeitstaktes zusammengesresst werden. Die Membranen haben ein oder mehrere Ventile, sowohl für Finlass (3) als Auslass (4).Fig. 1 shows an example of such a component construction. The compressors can be built from numerous bellows-like components, each consisting of made of two elastic, against harmful chemical effects and mechanical bnut Tung withstanding membranes supported by one or more reinforcing disks (1) (2), which are hermetically joined in their periphery and their center during of the suction cycle mutually apart and pressed together during the work cycle will. The diaphragms have one or more valves, both for Finlass (3) and Outlet (4).
Als -Material der Membranen und Verstärkerungsscheiben kann sogar Kunststoff in Betracht kommen. Zahlreiche Komponenten können, zentral zusammengebunden, aufeinander als Stapel gelegen, mit Elektromagneten (5) verschiedentlich bewegt werden, ud mit Wärmepumpekreislauf mittels biegsamen Leitungen (6) in Verbindung stenen. Wenn sie in jen Speicher (Gasbehälter) untergebracht eine, , dessen Gasinhait komprimiert werden soll, fallen die Saugleitungen aus. Die Stromrichtung jedes zweiten von obengenannten Elektromagneten oder Elektromagnetengruppen kann gewechselt werden, und dadurch auch ihre Nord/- Süd-Pole umgeschaltet werden, um die Energie des Netztstromes unmittelbar, ohne Motoren, zur linearen bewegung und Kompressionsarbeit verwandeln können. Das Gewicht der Komponenten und die Elastizität der Nembranen leisten Widerstand der sonst leichten Arbeit während des Saugtaktes, unterstutzen aber den Arbeitstakt entsprechend. Im Vergleich mit Kolbenkompressoren bleiben die Anlass-und Schmierungsschwierigkeiten aus.As a material of the membranes and reinforcing discs can even Plastic come into consideration. Numerous components, linked together centrally, can placed on top of one another as a stack, moved variously with electromagnets (5) ud connected to the heat pump circuit by means of flexible lines (6) stenen. If they are placed in the storage tank (gas container), its gas content should be compressed, the suction lines fail. The direction of the current every second the above-mentioned electromagnets or groups of electromagnets can be changed, and thereby also their north / south poles are switched to the energy of the mains current transform directly, without motors, to linear movement and compression work can. The weight of the components and the elasticity of the membranes offer resistance the otherwise easy work during the suction cycle, but support the work cycle corresponding. In comparison with reciprocating compressors, the starting and lubrication difficulties remain the end.
Fig. 2 zeigt die ög]ichkeit, dass jedc Komponente ihr eigenes Elektromagnetenpaar und deswegen ihre selbstständige Funktion hat und unbeweglich an ihre Umgebung befestigt werden kann, was die erstellung und Wartung etwas erleichtern mag.Fig. 2 shows the possibility that each component has its own pair of electromagnets and therefore has its independent function and is immovably attached to its environment which may make the creation and maintenance a little easier.
Dieselbe Figur zeigt ein Beispiel von Wärmepumpenkonstruktionen, wo der notwendige, zwar relativ kleine 'viedertemperatur-Wärmespeicher (#60°C) zentral im Wärmepumpesystem liegt, umgeben von Wärmepumpekreislaufphasen, die die Abwärme vom Speicher ausnutzen können, und die wieder selbst von kälteren Phasen umgeben einz, die keine Abwärme mehr zu der noch wärmeren Umgebung abgeben können.The same figure shows an example of heat pump designs where the necessary, relatively small, low-temperature heat storage (# 60 ° C) in the center lies in the heat pump system, surrounded by heat pump cycle phases that remove the waste heat from the storage tank, and which in turn are surrounded by colder phases one that can no longer give off any waste heat to the even warmer environment.
Von den 3 ineinander gelegenen, zylindrischen, halbhermetisch geschlossenen Behältern (7,8 u. 9) haben der innere (7) und der mittlere (8) isolierte Wandungen. Der Raum (10) zwischen dem äusseren und mittleren Behälter dient als Kurzzeitspeicher, wohin aus den, in verschiedenen Wärmequellen gelegenen Wärmetauschern das verdampfte Arbeitsmittel der 1. Ordnung (z.B. R12 B1) durch die Leitung (11) gebracht wird. Das Gas wird von Komponenten (12) komprimiert, zum ringförmigen Wärmetauscher (13) geleitet (gestrichelte Linie) und nach der Verflüssigung im zusätzlichen, auch ringförmigen Wärmetauscher (14) untergekühlt und weiter zu den Verdampfern (15) gebracht.Of the 3 nested, cylindrical, semi-hermetically sealed Containers (7, 8 and 9) have the inner (7) and the middle (8) insulated walls. The space (10) between the outer and middle container serves as a short-term storage where the evaporated from the heat exchangers located in different heat sources 1st order work equipment (e.g. R12 B1) is brought through line (11). The gas is compressed by components (12) to the ring-shaped heat exchanger (13) routed (dashed line) and after liquefaction in the additional, also ring-shaped Heat exchanger (14) subcooled and brought on to the evaporators (15).
In dem unteren Teil des Raumes (16) zwischen dem inneren und dem mittleren Zylinder wird von dem obengenannten Wärmetauscher (13) das flüssige Arbeitsmittel der 2. Ordnung (dienlich z.B. R 11) verdampft, um von den, im oberen Teil gelegenen Komponenten komprimiert und weiter zu dem Wärmetauscher (17) geleitet werden. Da wird die Latentwärme des Arbeitsmittels dem Wasser abgegeben. Nach der Verflüssigung wird das Arbeitsmittel untergekühlt (14) und wieder zum Raum (16) gebracht.In the lower part of the space (16) between the inner and the middle The cylinder becomes the liquid working medium from the above-mentioned heat exchanger (13) of the 2nd order (useful for example R 11) evaporates from the, in the upper part Components are compressed and passed on to the heat exchanger (17). There the latent heat of the working fluid is released into the water. After liquefaction the working fluid is subcooled (14) and brought back to the room (16).
Die im Wärmetauscher (14) in Verwahrung genommene Wärme kann auf verschiedensten Weisen als Wärmequelle zunutze kommen. Um eine Temperaturabnahme des Arbeitsmittels der 1. Ordnung unter die Verdampfungstemperatur in Wärmequellen zu erreichen, muss die Abkühlung mittels eines anderen Arbeitsmittels mit noch niedrigerem Siedepunkt, oder dann eines niedrigeren Saugdruckes im Kühlkreislaufe verwirklicht werden (nicht gezeichnet).The heat taken into custody in the heat exchanger (14) can be used in a wide variety of ways Wise as a heat source are used. To a decrease in temperature of the working medium the 1st order below the evaporation temperature in heat sources must be achieved the cooling by means of another working medium with an even lower boiling point, or then a lower suction pressure in the cooling circuit can be realized (not drawn).
