Abstract

The device performs optimal regulation between heating and solar collector with respect to the priority depending on the anticipated solar collector power. The solar current produced by at least one photocell is used for weather information for heating and causes an interruption of the conventional heating for hot water provision under certain conditions..

Description

Die Warmwasseraufbereitung durch Solarwärme wird durch die beste­ henden Anlagen nur mangelhaft ausgenutzt. Der Hauptverbrauch des Warmwassers findet in der Regel in den Morgenstunden statt. Zu dieser Zeit ist die Solarwärmeanlage durch die noch nicht wirksame Sonnen­ einstrahlung nicht aktiv. Das in den Boiler nachlaufende Kaltwasser wird von der konventionellen Heizung unabhängig davon, ob die Sonne sicht­ bar wird oder nicht, wieder auf Solltemperatur gebracht. Die Heizung greift also an einem Sonnentag der Solarwärme vor und verbraucht kon­ ventionelle Energie für eine Wärmeleistung, welche die Sonne 2-3 Stun­ den später gratis liefert.The hot water preparation by solar heat is the best existing systems are used poorly. The main consumption of the Hot water usually takes place in the morning. To this Time is the solar heating system due to the ineffective suns radiation not active. The cold water that runs into the boiler becomes conventional heating regardless of whether the sun is visible bar or not is brought back to the target temperature. The heating system thus anticipates solar heat on a sunny day and consumes con conventional energy for a heat output, which the sun 2-3 hours which later delivers for free.

Man braucht also ein System, welches in der Lage ist, rechtzeitig die Wet­ terentwicklung zu erkennen. Das heisst, rechtzeitige Information an die Heizungsregelung und damit bei Bedarf rechtzeitige Unterdrückung der konventionellen Heizung zur Warmwasseraufbereitung durch eine Nach­ ladesteuerung.So you need a system that is able to get the wet in time to recognize development. That means timely information to the Heating control and therefore timely suppression of the conventional heating for hot water preparation by an after loading control.

Lösung: Eine günstig auf dem Dach angebrachte Photovoltaikanlage (ca. 30 cm2) liefert bei Sonnenschein Solarstrom. Dieser Solarstrom (nur wenige mA sind notwendig) steuert einen elektrischen Schalter, welcher in der Heizungsregelung die Warmwasseraufbereitung durch konventionelle Heizung unterbricht. Die Solarzellen müssen der Heizungs­ regelung die aufgehende Sonne sofort mitteilen, so dass es im Morgenbe­ trieb (Duschen etc.) zum sofortigen Heizungsstop kommt. Das Boilerwas­ ser wird also nicht unnötig und voreilig durch die konventionelle Heizung aufgeheizt. Kommt es zu einer Wetterverschlechterung, liefert die Zelle weniger Strom. Fällt der Strom unter einem bestimmten Schwellwert (variabel einstellbar), wird die Warmwasseraufbereitung wieder durch die konventionelle Heizung übernommen. Dies allerdings erst nach einer ebenfalls variabel einzustellenden Zeitverzögerung. Diese Zeitverzögerung überbrückt eine kurze Eintrübung oder eine momentane Blockierung der Sonne durch eine Wolke. Braucht man allerdings nach dem Morgenbetrieb sofort wieder warmes Wasser, so ist die Nachladesteuerung durch einen manuellen Schalter zu unterbrechen und somit jederzeit eine Rückkehr zum alten Technikstatus zu erreichen. Um eine lückenlose Nachladesteu­ erung zu erreichen, muss die kleine Photovoltaikanlage 3 Solarzellen auf­ weisen. Damit wird dem Sonnenlauf über den Tag hinweg Rechnung ge­ tragen.Solution: An inexpensive photovoltaic system (approx. 30 cm 2 ) on the roof provides solar power in the sunshine. This solar power (only a few mA is necessary) controls an electrical switch, which in the heating control interrupts the hot water preparation by conventional heating. The solar cells must immediately inform the heating control that the sun is rising so that the heating stops immediately in the morning (showers etc.). The boiler water is not heated unnecessarily and prematurely by the conventional heating. If the weather deteriorates, the cell delivers less electricity. If the current falls below a certain threshold value (variably adjustable), the hot water is again taken over by the conventional heating. However, this only after a time delay that can also be set variably. This time delay bridges a brief clouding or a momentary blocking of the sun by a cloud. However, if you need warm water again immediately after the morning operation, the reload control must be interrupted by a manual switch and a return to the old technology status can be achieved at any time. In order to achieve complete reload control, the small photovoltaic system must have 3 solar cells. This takes the course of the sun into account throughout the day.

Solarzelle 1 muss in Richtung der aufgehenden Sonne zeigen. Damit kann sie die Heizungsregelung rechtzeitig über die aufgehende Sonne informie­ ren und die Nachladesteuerung für das Brauchwasser aktivieren.Solar cell 1 must point in the direction of the rising sun. So that can inform the heating control in good time about the rising sun and activate the recharge control for the hot water.

Solarzelle 2 zeigt in etwa in die Richtung, in der die Sonnenkollektoren Ausgerichtet sind, also in etwa Richtung Süden. Damit ist auch nach dem Sonnenaufgang und dem Wegdrehen der Sonne von der Solarzelle 1 in Richtung Süden weiterhin der notwendige Solarstrom für die Nachlade- Steuerung sichergestellt.Solar cell 2 points approximately in the direction in which the solar panels Aligned, i.e. towards the south. This is also after Sunrise and the turning away of the sun from the solar cell 1 in To the south, the solar power required for recharging Control ensured.

Solarzelle 3 hat die gleiche Aufgabe für die Nachmittags- und Abend- Stunden, also Ausrichtung nach Westen.Solar cell 3 has the same task for the afternoon and evening Hours, so west-facing.
