Abstract

The method involves utilizing a combined heat and power unit for maintaining a public power supply temperature, and using electric current in a public network and/or for the supply to heat pumps. Waste heats are supplied to a public power supply via a buffer and a heat exchanger. The excess heat energy is utilized for operating an absorption refrigerator during the operation of the combined heat and power unit outside a heating period. A design of a combination-power-heat coupling is selected in such a manner that a maximum utilization rate is achieved.

B. ein Biomasse-BHKW) und eine Absorptionskältemaschine mit Wärme- und Kälteenergie versorgt. An das, auf niedrigem Temperaturniveau betriebene Versorgungsnetz, werden dezentrale Wärmepumpen angeschlossen. Für den Fall der Kälteanforderung werden die Wärmepumpen im Bypass betrieben.at the energy supply of residential and commercial properties with the cold district heating becomes a closed supply network consisting of supply and return lines from uninsulated Plastic pipes through a central heat generator (eg a biomass CHP) and an absorption chiller with heat and cold energy provided.

R. zwischen 55 und 90°C. Bei jedem Verbraucher ist eine Wärmeübergabestation eingerichtet, über welche Raumheizung und Brauchwarmwasserbereitung versorgt werden. Die Wärmeenergie wird i. d. R. über einen zentralen Kessel, z. B. mit Holzhackschnitzeln als Energieträger, erzeugt. Diese Systeme können allerdings die hohen Erschließungskosten nur dann wettmachen, wenn viel Wärme auf kleinem Raum abgenommen wird. Dies ist bei Baugebieten mit großzügigen Grundstücken und Einfamilienhausbebauung i. d. R. nicht der Fall.Known are local heating systems, the single buildings over insulated and thus expensive and elaborate Lines with heat supply. The flow temperatures of these systems are i. d.

Im Sommer, bei geringer Wärmeabnahme, besteht das Problem, dass dennoch eine hohe Vorlauftemperatur im Nahwärmenetz vorgehalten werden muss um die hygienische Brauchwarmwasserbereitung zu gewährleisten. Aufgrund der hohen Temperaturen im Nahwärmenetz muss mit ca. 10 bis 15% Wärmeverlusten gerechnet werden.in the Summer, with low heat loss, exists the problem that still a high flow temperature in the district heating network must be held to the hygienic domestic hot water to ensure. Due to the high temperatures in the district heating network, approx. 10 to 15% heat loss be counted.

Bekannt sind Nahwärmesysteme, die auf niedrigem Temperaturniveau betrieben werden und auf gedämmte Leitungen verzichten. Anstelle einer Wärmeübergabestation wird eine Wärmepumpe installiert, die aus dem Versorgungsnetz die benötigten Vorlauftemperaturen erzeugen. Anstelle der bekannten Wärmepumpensysteme mit Erdsonden oder -kollektoren, Grundwasserbrunnen oder Luft/Wasser-Wärmetauschern wird das Versorgungsnetz zentral mit Wärme versorgt.Known are local heating systems, which are operated at a low temperature level and insulated pipes without. Instead of a heat transfer station becomes a heat pump installed, the required supply temperatures from the supply network produce. Instead of the known heat pump systems with geothermal probes or collectors, groundwater wells or air / water heat exchangers the supply network is supplied with heat centrally.

Als Wärmequellen werden unter anderem Oberflächengewässer, Erdreich durch Sondenfelder oder Abwasser durch Wärmerückgewinnungssysteme erschlossen. Um diese Wärmequellen zu nutzen, müssen aber entsprechende Standortbedingungen erfüllt sein.When heat sources Among other things, surface waters, soil through probe fields or wastewater through heat recovery systems.
