Abstract

The equipment uses solar heat to provide washing water, room heating and/or room cooling. A hot-water storage tank is heated via a solar air collector and fan using an air-to-water heat exchanger. This then supplies washing water or alternatively after shutting off the collector by a valve, is used, in conjunction with the same heat exchanger and fan, to heat air for warming the room. As a third alternative, the heat exchanger is shut off and fan and air collector are used to heat the room, and as a fourth the fan blows air over the heat exchanger, which is supplied from a cold water source, to cool the room.

Solare Mehrzweck-AnlageSolar multipurpose system

Die solare Erwärmung von Brauchwasser verspricht selbst in Ländern mit niedriger Sonneneinstrahlung in wenigen Jahren wirtschaftlich zu werden, in südlichen Ländern mit hoher Einstrahlung ist sie es bei Verwendung geeigneter Kollektoren schon heute. In südlichen Ländern besteht zusätzlich der Bedarf an solarer Kühlung im Sommer, in vielen Fällen auch an solarer Heizung im Winter.The solar heating of domestic water is promising even in countries to become economical with low solar irradiation in a few years, in southern countries with high irradiation it is when using suitable collectors today. In southern countries there is also a need for solar cooling in summer, in many cases also on solar heating in winter.

Solare Brauchwassererwärmung und Hausheizung werden vielfach kombiniert, wobei das solar erwärmte Wasser zugleich Wärmetransportmedium und Wärmequelle für die Hausheizung ist. Die Lösung ist in der Mehrzahl der Fälle nicht anwendbar, da innerhalb der in südlichen Ländern gebauten Häuser gewöhnlich kein Heizungssystem für Wasser-Radiatoren besteht, seine Einrichtung für solare Warmwasserheizung nicht wirtschaftlich ist. Es wird daher die solare Raumheizung meist mit solar erwärmter Luft und abgetrennt vom solaren Brauchwassersystern durchgeführt.Solar water heating and house heating are often combined, whereby the solar heated water is at the same time a heat transport medium and a heat source for the house heating. The solution is in not applicable in the majority of cases as there is usually no heating system in houses built in southern countries for water radiators, its installation for solar hot water heating is not economical. It therefore becomes the solar Room heating is usually carried out with solar heated air and separated from the solar hot water system.

Die solare Raumkühlung ist noch in der Entwicklung. Da man ausschliesslich die Verwendung von Absorptionskühlern im Auge hat, werden diese mit Flüssigkeitskollektoren mit Temperaturen von 7o bis 9o C, d.h. über der Temperatur des üblichen Brauchwassers geplant. Für kleinere Wohneinheiten dürften sie noch auf Jahre hinaus unwirtschaftlich sein.Solar room cooling is still in development. Since you are exclusively With the use of absorption chillers in mind, these will be with liquid collectors with temperatures of 7o to 9o C, i.e. planned above the temperature of the usual service water. For smaller residential units, they are likely to continue for years also be uneconomical.

Die Verwendung von Strahlungskühlern für Raumkühlung wurde ebenfalls schon vorgeschlagen. Als Einzweckanlage hat das Verfahren jedoch in Anbetracht der limitierten Kühlleistung nur bei sehr niedrigen Nachthimmeltemperaturen Aussicht, wirtschaftlich zu werden.The use of radiant coolers for space cooling was also made already suggested. As a single-purpose system, however, in view of the limited cooling capacity, the process only works at very low levels Night sky temperatures prospect to become economical.

Das wirtschaftliche Potential der Verfahren verbessert sich jedoch entscheidend, wenn sie apparativ kombiniert werden, so dass die spezifischen Investitionskosten für jede einzelne Teilfunktion stark erniedrigt werden. Dies ist in überraschend einfacher und damit billiger Weise dann möglich, wenn die Erwärmung des Brauchwassers über solar erwärmte Luft erfolgt, da die erforderlichen Luftkollektoren um eine Zehnerpotenz billiger sind als Wasserkollektoren, undHowever, the economic potential of the process is improving crucial if they are combined in terms of equipment, so that the specific investment costs for each individual sub-function are high to be humiliated. This is possible in a surprisingly simple and therefore cheaper way when the domestic water is heated takes place via solar heated air, since the necessary air collectors are cheaper than water collectors by a power of ten, and
