Wärmepumpenheizzentralen zur Beheizung von Gebäuden und zur Brauchwassererwärmung
üblicher Bauart, wie sie in den Firmenunterlagen von Siemens, Ochsner und in der
Arbeitsmappe des Initiativkreises Wärmepumpe e.V. beschrieben sind, bestehen neben der
primären Wärmequelle und der Wärmepumpe aus mindestens zwei getrennten Speicherndem
Puffer- bzw. Trennspeicher und dem Speicher zur Brauchwassererwärmung. Hierdurch
entsteht ein erhöhter Platzbedarf und die Gesamtkosten der Anlage steigen.Heat pump heating systems for heating buildings and domestic water
of the usual design, as described in the company documents of Siemens, Ochsner and in the
The workbook of the Heat Pump Initiative Group eV contains the
primary heat source and the heat pump from at least two separate storage
Buffer or separation tank and the tank for domestic water heating. This
This results in an increased space requirement and the overall costs of the system increase.
Die Einzelelemente der Anlage werden für jedes Projekt neu zusammengestellt.The individual elements of the system are reassembled for each project.
Bei der Auslegung von Wärmepumpenheizzentralen üblicher Bauart gemäß den geltenden Vorschriften zur Dimensionierung von Heizungsanlagen ist für Außentemperaturen unterhalb der in o.g. genannten Vorschrift festgelegten Außentemperaturen die Wärmeversorgung zur Gebäudebeheizung und Brauchwassererwärmung nicht mehr vollständig abgesichert. Es müssen die Anlagen zur Absicherung einer ausreichenden Wärmeversorgung bezüglich der Wärmepumpe und der Wärmequelle überdimensioniert werden., Hierdurch entstehen wiederum erhebliche Mehrkosten.When designing heat pump heating centers of the usual type in accordance with the applicable regulations for dimensioning heating systems, the heat supply for heating the building and domestic water heating is no longer fully ensured for outside temperatures below the outside temperatures specified in the above-mentioned regulation. The systems must be oversized to ensure an adequate heat supply with regard to the heat pump and the heat source. This in turn results in considerable additional costs.
Um diese Überdimensionierung zu umgehen werden in o.g. Literatur bivalent arbeitende Wärmepumpenheizzentralen beschrieben, denen unterhalb des Bivalenzpunktes eine weitere Energiequelle wie Gas- oder Öl-Heizungssysteme zugeschalten werden. Dabei ist sowohl ein Prallelbetrieb, als auch der Einzelbetrieb jeder einzelnen Heizanlage möglich. Nachteilig ist bei dieser Art der bivalenten Arbeitsweise, dass zwei Energieträgersysteme für den Betrieb der Heizanlage benötigt werden.In order to avoid this over-dimensioning, bivalent heat pump heating systems are described in the above-mentioned literature, to which an additional energy source such as gas or oil heating systems is connected below the bivalence point. Both parallel operation and individual operation of each heating system are possible. The disadvantage of this type of bivalent operation is that two energy carrier systems are required to operate the heating system.
Übliche Brauchwassererwärmungsanlagen in Wärmepumpenheizungsanlagen arbeiten als Speicher, d.h. das erwärmte Brauchwasser wird in einem speziellen Speicher vorgehalten. Da Wärmepumpenanlagen wegen ihres Wikungsgrades mit möglichst geringen Ausgangstemperaturen von < 600C arbeiten, ist zum Abbau biologischer Verunreinigungen bei Speichersystemen mit Speichervolumina >=300 1 ein gesondertes Brauchwassererwärmungssystem erforderlich, welches in definierten Zeitabständen eine Erwärmung des gespeicherten Brauchwassers über 600C absichert. Die Brauchwasserspeicher müssen aus hochveredelten Materialien bestehen, um eine chemische Verunreinigung des Bauchwassers auszuschließen. Hierdurch entstehen erhebliche Mehrkosten.Conventional domestic water heating systems in heat pump heating systems work as storage tanks, ie the heated domestic water is stored in a special storage tank. Since heat pump systems work with the lowest possible starting temperatures of < 60 0 C due to their efficiency, a separate domestic water heating system is required to break down biological contamination in storage systems with storage volumes >=300 1, which ensures that the stored domestic water is heated to over 60 0 C at defined intervals. The domestic water storage tanks must be made of high-quality materials to prevent chemical contamination of the domestic water. This results in considerable additional costs.
Für den Betrieb von Wärmepumpenheizzentralen zur Gebäudebeheizung und Brauchwassererwärmung in Kombination mit Solarkollektoranlagen wird üblicherweise die mittels der Solarkollektoren gewonnen Wärmeenergie unmittelbar dem Brauchwasserspeicher zur Brauchwassererwärmung oder zur Heizungsunterstützung der primären Wärmequelle für die Wärmepumpe zugeführt. Bei der Kombination der Solarkollektoranlage mit der Brauchwasserwärmung sind niedrige Solarenergiegewinne nicht nutzbar.When operating heat pump heating systems for building heating and domestic water heating in combination with solar collector systems, the heat energy gained by the solar collectors is usually fed directly into the domestic water storage tank for domestic water heating or to support the heating of the primary heat source for the heat pump. When combining the solar collector system with domestic water heating, low solar energy gains cannot be used.
Bei üblichen monovalent arbeitenden Wärmepumpenheizzentralen ist im Havariefall der Wärmepumpe keine Grundversorgung mit Wärmeenergie möglich, d.h. sowohl die Gebäudebeheizung als auch die Brauchwasserwärmung sind nicht arbeitsfähig.In the case of conventional monovalent heat pump heating systems, a basic supply of heat energy is not possible in the event of a heat pump failure, i.e. both the building heating and the domestic water heating are not able to function.
Übliche, wie in o.g. Literatur beschriebene Wärmepumpenheizzentralen sind bei der Sanierung von Gebäuden mit Heizungssytemen mit Vorlauftemperaturen >60°C nicht einsetzbar. Es muss, wenn Wärmepumpenheizentralen zum Einsatz kommen sollen, die gesamte Heizungsanlage auf ein Temperatursystem mit Heizungsvorlauftemperaturen <60°C umgestellt werden. Diese Umstellung ist mit hohen Kosten verbunden und macht somit die Umstellung auf den Einsatz der Wärmepumpenheizung unökonomisch.Conventional heat pump heating systems as described in the above literature cannot be used when renovating buildings with heating systems with flow temperatures >60°C. If heat pump heating systems are to be used, the entire heating system must be converted to a temperature system with heating flow temperatures <60°C. This conversion is associated with high costs and therefore makes the conversion to the use of heat pump heating uneconomical.
