Abstract

By using a site alongside a house or building, a heat pump arrangement recuperates heat from the building itself. Extending from the side of the building below ground level is a heat recuperator coil (WS), housed inside a horizontal chamber (HR). This consists of a tube constructred from two shells. This coil is surrounded by gravel, rock, stones or ballast (PL) in an open topped container (EW) a certain distance under ground level. Water collects in this container. Waste or sewage watfer, and off gases from the heating system then pass through the tube (HR) and around the coil (WS) and heat is given up to the water around it.

Description

Anlage 2Annex 2

B E S C H R E I B U N G Gegenstand der Patentanmeldung ist ein Wärme-Pumpensystem mit intergriertem Wärmedienverbund.B E S C H R E I B U N G The subject of the patent application is a heat pump system with integrated thermal media network.

Wärmepumpensysteme konventioneller Bauart benutzen entweder die Au3enluft, das Erdreich oder Grund-bzw. Flußwasser jeweils getrennt fUr sich als Wärmequellen. Dabei benötigt man fUr die Heizwassererwärmung fUr Zentralheizungen it relativ hohen Vorlaufterperaturen sehr große Mengen bzw. Flächen der wärmeführenden Medien Luft, Wasser oder Erdreich.Conventional heat pump systems use either the outside air, the soil or ground or. River water separately as heat sources. For the heating water for central heating it is necessary to have relatively high Upstream temperatures very large amounts or areas of the heat-carrying media air, Water or soil.

Der konventionelle Einsatz von Wärmepumpen zur Vollheizung von Gebäuden hat zusammengefaßt folgende Nachteile bzw. Grenzens - Hohe Vorlauftemperaturen bedingen einen geringeren Wirkungsgrad der Wärmepumpen oder umgekehrt einen erhöhten Investitionsaufwand bei. Heizsystem bei stärkerer Absenkung der Vorlauftexperotur und gleichzeitig geringerer Effektivität der Wärmeübertragung durch Luftkonvektion im Raum.The conventional use of heat pumps for full heating of buildings has summarized the following disadvantages or limits - high flow temperatures cause a lower efficiency of the heat pumps or, conversely, an increased investment at. Heating system with a greater reduction in the flow experience and at the same time less Effectiveness of heat transfer through air convection in the room.

- Bei. Wärmemedium Luft werden sehr große Mengen an Außenluft benötigt und eine vertretbore wirtschaftliche Nutzung ist nur bis zu Lufttemperaturen von + 50 C gegeben. Hohe Luftgeräusche und der Ausfall bei niedrigen Außente.peroturen sowie hohe Anlagenkosten sind die Hauptnachteile des Wärmemediums Außenluft.- At. As a heat medium, air, very large amounts of outside air are required and a justifiable economic use is only up to air temperatures of + 50 C given. High air noises and failure at low external ducks and high system costs are the main disadvantages of outdoor air as a heating medium.

- Beim Wärmemedium Wasser ist die begrenzte Verfugbarkeit von Grund-, See- oder Flußwasser sowie der Aufwond für die Wasserzuführung und -ableitung (Wasser- und Sickerbrunnen) von Nachteil.- In the case of water as a heating medium, the limited availability of ground, Lake or river water as well as the expense of supplying and draining water (water and drainage wells) are disadvantageous.

- Beim Wärmemedium Erdreich werden sehr große Flächen und lange Wärmetauscherleitungen benötigt, z.B. bei einen keinen Einfamilienhaus ca. 500 m² Erdfläche und 1 500 m Rohrlänge,was sehr unwirtschaftlich ist.- In the case of the ground as a heating medium, very large areas and long heat exchanger lines are required required, e.g. for a single-family house approx. 500 m² earth area and 1,500 m Pipe length, which is very uneconomical.

- Aus den vorgenannten Gründen ist die Wärmepumpe bislang effektiv nur als Zusatzheizung einsetzbar bei gleichzeitig reduzierte. Wirkungsgrad und hohen Anlagekosten.- For the reasons mentioned above, the heat pump has so far been effective Can only be used as additional heating with reduced. Efficiency and high Investment costs.

Anlage 2 Das hier beschriebene Wärmepumpensystem ist mit einer Wärmestrahlungs-System zur Raumheizung und -kuhlung (siehe Patentanmeldung P 27 44 087.5 ) integriert, das mit extrem niedrigen Vorlauftemperaturen von i.M. 300 C arbeitet und als primäres Wärmemedium Uberall verfUgbares Oberflächenwasser bzw. hochliegendes Grundwasser benutzt und die Wärmemedium Erdreich und Luft sowie Abwdrme als sekundäre Wärmequellen integriert.Appendix 2 The heat pump system described here is with a heat radiation system integrated for room heating and cooling (see patent application P 27 44 087.5), that with extremely low flow temperatures of i.M. 300 C works and as a primary Heat medium Surface water available everywhere or high-lying groundwater used and the heat medium soil and air as well as waste heat as secondary heat sources integrated.

Wasser als stehendes Wärmemedium hat den Vorteil, daß die Wärme bis zum Gefrierpunkt entzogen werden kann und somit die gesamte Latentworme im Vereisungsbereich zur Verfügung steht, die pro kg und 0C dem achtzigfochen Wärmebetrog im Normalbereich entspricht.Water as a standing heat medium has the advantage that the heat is up to can be withdrawn to freezing point and thus the entire latent heat in the icing area is available that per kg and 0C to the eighty-fold heat bed in the normal range is equivalent to.

Der hohe Wirkungsgrad des Gesamt systems verbunden mit der Nutzung der nachströmenden Warme des Grundwasser bzw. des Erdreichs sowie der Abwdrme der Aggregate und der Abwässer ermöglichen relativ kleinfldchige Würmetauscheranlagen und eine sehr wirtschaftliche Betriebsweise.The high degree of efficiency of the overall system combined with its use the inflowing heat of the groundwater or the soil as well as the waste heat of the Aggregates and the wastewater enable relatively small-area Wür exchanger systems and a very economical mode of operation.

Die Funktionsweise des Wrmepumpensystems mit integrierten Wdrmequellen geht aus der beiliegenden Funktionszeichnung hervor: (Abb.l) Oberflächenwasser (OW) bzw. Grundwasser (GW) so..elt sich in einer Erdwanne (EW), die oberhalb des niedrigsten Grundwasserspiegels mit einer Dichtungsbahn ausgelegt ist. In diese Erdwanne (EW) wird in einer Packlage (PL) aus Grobkies, Schotter oder entsprechende.How the heat pump system works with integrated heat sources is evident from the accompanying functional drawing: (Fig. 1) Surface water (OW) or groundwater (GW) is in a basin (EW) that is above the lowest Is designed with a waterproofing membrane. In this earth basin (EW) is made of coarse gravel, crushed stone or equivalent in a packing layer (PL).

Material ein Hüllrohr (HR) mit der Wärmetauscherschlange (WS) eingebracht, durch die mittig die Wärmetouscherrohre der Abwässer (AW), base (AG) und Ab-und Zuluft gefuhrt werden.Material of a cladding tube (HR) with the heat exchanger coil (WS) inserted, through the middle of the heat exchanger pipes of the waste water (AW), base (AG) and waste and Supply air can be guided.

Der Wdrmeaustausch erfolgt so, daß dem Wasser im seitlich offenen, aus zwei Halbschalen bestehenden Hüllrohr (HR) und in der Packlage die fiärme bis zum Gefrierpunkt entzogen wird. Durch die Vereisung des Wassers stehen beträchtliche Wärmemengen zur Verfugung, sodaß der wärmebedarf von Ein-und Zweifamilienhäusern durch relativ kleine und wirtschaftliche Anlagen gedeckt werden kann, zumal die Vereisung durch die Abwärme und die nachströmende Erd- oder Grundwasserwärme laufend wieder rückgängig gemacht wird. Um eine zu starke Auskühlung der Deckschicht Uber der Erdwonne zu verhindern, kann über der Packlage eine Dämmschicht eingebracht werden.The heat exchange takes place in such a way that the water in the open, cladding tube (HR) consisting of two half-shells and the fiärme bis in the packing position is withdrawn to freezing point. Due to the icing of the water there are considerable Amount of heat available, so that the heat demand of one and two-family houses can be covered by relatively small and economical systems, especially since the Icing caused by the waste heat and the inflowing geothermal or groundwater heat continuously is reversed. To avoid excessive cooling of the top layer To prevent the earth's bliss, an insulation layer can be placed over the packing layer will.
