Abstract

Solar cell for utilising solar heat comprises a heating element for liquids (1) which is exposed to the sunlight and which is combined with the evaporator (4) of a heat pump (6). The heating element may be in the form of two pipes, one (3) for the water cycle and the other (4) for the refrigerant cycle. The two pipes may be arranged one above the other in a common multi-chamber finned pipe, or one beside the other in a common plate. The heat pump is only used at low temps., where there is a temp. difference between evaporation and condenser of 40 deg.C, i.e. when there is little solar radiation, so as to increase the total utility effect of the appts. and therefore allow an increase in household heating.

Einrichtung zur Ausnützung der SonnenwärmeFacility for utilizing the sun's heat

Ein wesentliches Problem bei der Umwandlung der Sonnenenergie in Wärme ist der Nutzeffekt bei geringer Sonneneinstrahlung. Bekannte Sonnenkollektoren bestehen meist aus einer geschwärzten, mit Wasser gefüllten Absorptionsfläche, die sich hinter einer, die Sonnenstrahlen durchlassenden Abdeckung befindet. Da die Sonne nicht ständig scheint und bei größtem Wärmebedarf im Winter am wenigsten, ist die Nutzung auch geringer Temperaturdifferenzen von Bedeutung.A major problem in converting solar energy into heat is the benefit when there is little solar radiation. Well-known solar collectors usually consist of a blackened, water-filled absorption surface, which is behind one that lets the sun's rays through Cover is located. Since the sun does not shine all the time and least when there is a need for heat in winter, the use of even small temperature differences is important.

Bekannt sind weiterhin Wärmepumpen, die durch Zuführung von elektrischer Energie mittels einer Verdichtung geringe Wärmedifferenzen wirtschaftlich nutzen können.Also known are heat pumps that are supplied by supply of electrical energy can use small heat differences economically by means of compression.

Erfindungsgemäß wird vorgeschlagen, den Sonnenkollektor und den Verdampfer einer Wärmepumpe zu vereinen. Dies kann in mehreren Arten erfolgen und das Prinzip ist, daß der Sonnenkollektor zwei getrennte Rohrsysteme aufweist. Das eine Rohrsystem enthält Wasser· oder ein anderes Heizmedium, das zweite Rohrsystem ein Kältemittel. Bei hohen Temperaturdifferenzen arbeitet nur der Sonnenkollektor. Eine Wärmepumpe ist, wie bekannt, bei hohen Temperaturen zwischen Verdampfer und Kondensator unwirtschaftlich (eineAccording to the invention it is proposed to combine the solar collector and the evaporator of a heat pump. this can be done in several ways and the principle is that the solar collector has two separate pipe systems. One pipe system contains water or another heating medium, the second pipe system a refrigerant. At high Temperature differences only work the solar collector. As is well known, a heat pump is at high temperatures between evaporator and condenser uneconomical (a

Eine wirtschaftliche Nutzung der Wärmepumpe ist erfahrungsgemäß bei dem Kältemittel R 1 2 erst ab ί *** 4 gegeben, was einer Temperaturdifferenz Verdampfung Kondensator von 4o°C entspricht.) Bei niedrigen Temperaturen, d.h. bei geringer Sonneneinstrahlung, wird die Wärmepumpe zugeschaltet, so daß der gesamte Nutzeffekt der Anlage sich erhöht und damit eine wesentliche Verbesserung des Wärmehaushaltes ermöglicht wird.Experience has shown that the heat pump can only be used economically with refrigerant R 1 2 from ί *** 4, which corresponds to a temperature difference evaporation condenser of 40 ° C the overall efficiency of the system is increased and thus a significant improvement in the heat balance is made possible.

Der Kanal 4 stellt den Verdampfer einer Wärmepumpenanlage dar, deren Verdichter 6 das Kältemittel über einen Kondensator 9 und eine Drossel 8im Kreislauf fördert. Der Kondensator 9 befindet sich in einem Wärmetauscher 1o, wo das Nutzwasser für Heizung, Bad u.dgl. aufgewärmt wird. Die Känalsysteme 3 und 4 im Aufheizelement 1 (Sonnenkollektor) sind gemäß Fig. 2 in einemmehrkammerigen Rippenrohr übereinander angeordnet und gemäß Fig. 3 können sie auch nebeneinander liegen, während die Fig. 4 eine Anordnung mit übereinanderliegenden getrennten Rippenrohren veranschaulicht. In Fig. 5 sindAs can be seen from the drawing, a heating element 1, which consists of an insulating glass 2, a thermal insulation 5 and a channel system arranged in between, which has a channel 3 for the water cycle and has a channel 4 for the refrigerant circuit, which is exposed to solar radiation. Channel 4 represents the vaporizer a heat pump system, whose compressor 6 the refrigerant via a condenser 9 and a throttle 8 promotes the cycle. The condenser 9 is located in a heat exchanger 1o, where the useful water for heating, bathroom and the like is warmed up. The duct systems 3 and 4 in the heating element 1 (solar collector) are shown in FIG. 2 in a multi-chamber finned tube arranged one above the other and according to FIG. 3 they can also lie next to one another, while FIG. 4 shows an arrangement with one above the other separate finned tubes illustrated. In Fig. 5 are

Die übrigen mehrkammerigen Wärmetauschrohre können auch durch Strangpressen aus Aluminium oder Kupfer leicht hergestellt werden.the channel systems 3, 4 side by side in a common Plate 11 arranged, which consists of two metal sheets in the roll welding process can be easily made, the weld in the channels by previously applied Release agent is prevented and then, after rolling, the channels are widened by inflation. The remaining Multi-chamber heat exchange tubes can also be easily manufactured from aluminum or copper by extrusion.
