Abstract

In the heating assembly with heat pump(s), the compressor drive is provided particularly by a squirrel cage rotor motor for warming the heating medium. So as to give an improved energy yield during heat generation, heat taken off from the motor, partic. from the motor windings(17) is supplied to the heating medium for additional thermal economy. The heat take-off from the motor is specif. undertaken by a coolant circuit associated with the motor. The housing is composed of two concentric tube sections(11, 12) with a hollow space(13) in between them, with inlet and outlet ducts out of line.

Description

Heizungsanlage mit Wärmepumpe.Heating system with heat pump.

Beschreibung: Die Erfindung betrifft eine Heizungsanlage mit Wärmepumpe, die einen durch einen Motor, insbesondere Kurzschlußläufermotor, angetriebenen Kompressor zur Erwärmung eines Heizmediums (Heizungswasser) aufweist. Description: The invention relates to a heating system with a heat pump, a compressor driven by a motor, in particular a squirrel cage motor for heating a heating medium (heating water).

Bei bekannten Heizungsanlagen bleibt die Abwärme der Kompressoren von Wärmepumpen sowie des Antriebs für die Kompressoren, insbesondere die Abwärme eines Elektromotors nach dem Kurzschlußläuferprinzip, ungenutzt. Die auftretende Abwärme wird vielmehr durch ein Gebläse ins Freie abgeleitet. In known heating systems, the waste heat from the compressors remains of heat pumps and the drive for the compressors, especially the waste heat an electric motor based on the squirrel cage principle, unused. The occurring Rather, waste heat is dissipated outside by a fan.

Der Erfindung liegt die Aufgabe zugrunde, eine Heizungsanlage mit Wärmepumpe bzw. Kompressor dahingehend weiterzuentwickeln, daß eine bessere Energieausbeute bei der Wärmegewinnung erzielt wird.The invention is based on the object of having a heating system To further develop the heat pump or compressor so that a better energy yield is achieved in heat recovery.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Heizungsanlage dadurch gekennzeichnet, daß die Abwärme des Motors, insbesondere der Feldwicklungen desselben, dem Heizmedium zur (zusätzlichen) Erwärmung desselben euführbar ist.The heating system according to the invention is used to solve this problem characterized in that the waste heat from the motor, in particular the field windings of the same, the heating medium for (additional) heating of the same can be euführbar.

Der Motor, insbesondere ein Kurzschlußläufermotor, für den Antrieb des Kompressors ist mit einem Kühler versehen, der einen Hohlraum bildet, durch den das aufzuheizende Medium hindurchgeleitet wird. Der Kühler ist als haubenartiges Gehäuse ausgebildet mit zwei den Motor konzentrisch umgebenden Rohrabschnitten, zwischen denen der Hohlraum zur Aufnahme des wärmeabführenden Heizmediums gebildet ist.The motor, especially a squirrel cage motor, for the drive the compressor is provided with a cooler that forms a cavity through which the medium to be heated is passed through. The cooler is as hood-like Housing designed with two pipe sections concentrically surrounding the motor, between which the cavity for receiving the heat-dissipating heating medium is formed is.

Um einerseits eine optimale Ableitung der Motorwärme bzw.On the one hand, to ensure optimal dissipation of engine heat or

der Wärme der Feldwicklung desselben und andererseits eine möglichst verlustfreie Erwärmung des Heizmediums zu erreichen, liegt nach einem weiteren Vorschlag der Erfindung die Wicklung des Motors (Stator) unmittelbar am inneren Rohrabschnitt des Gehäuses an.the heat of the field winding of the same and on the other hand one as possible A further suggestion is to achieve loss-free heating of the heating medium the invention, the winding of the motor (stator) directly on the inner pipe section of the housing.

Einzelheiten eines Kompressors bzw. eines Motors für den Antrieb desselben werden nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung gibt einen Kurzschlußläufermotor für den Antrieb eines Kompressors im Vertikalschnitt wieder.Details of a compressor or a motor for driving the same are hereinafter based on an embodiment shown in the drawing explained in more detail. The drawing shows a squirrel cage motor for the drive of a compressor in vertical section.

Der Elektromotor (Kurzschlußläufermotor) ist innerhalb eines Gehäuses 10 angeordnet. Dieses besteht aus zwei konzentrisch ineinandersitzenden Rohrabschnitten 11 und 12. Zwischen diesen wird ein Hohlraum 13 gebildet. Oben ist das Gehäuse durch eine Deckelplatte 14 verschlossen. Ein im unteren Bereich am Gehäuse 10 sitzender Flansch 15 ist mit einem Rotorflansch 16 verbunden.The electric motor (squirrel cage motor) is inside a housing 10 arranged. This consists of two concentric pipe sections 11 and 12. A cavity 13 is formed between these. The case is through at the top a cover plate 14 closed. A seated in the lower area on the housing 10 Flange 15 is connected to a rotor flange 16.

Beim Betrieb des Motors zum Antrieb eines Kompressors entsteht Wärme in den Wicklungen 17 des Motors. Diese Wärme wird durch ein Heizmedium aufgenommen, welches zu diesem Zweck durch den Hohlraum 13 zwischen den Rohrabschnitten 11 und 12 hindurchgeleitet wird. Das Heizmedium bewirkt dadurch einerseits die erforderliche Kühlung des Motors bzw. der Wicklung 17. Zum anderen wird dadurch das in die Heizungsanlage geförderte Heizungswasser zusätzlich erwärmt. Zur Einführung des Heizmediums in den Hohlraum 13 ist ein Eintrittsstutzen 18 und zur Ableitung des erwärmten Mediums ein Austrittsstutzen 19 am Gehäuse 10 angeordnet.When the engine is operated to drive a compressor, heat is generated in the windings 17 of the motor. This heat is absorbed by a heating medium, which for this purpose through the cavity 13 between the pipe sections 11 and 12 is passed through. On the one hand, the heating medium thereby effects the required Cooling of the motor or the winding 17. On the other hand, this also affects the heating system pumped heating water is additionally heated. To introduce the heating medium in the cavity 13 is an inlet connection 18 and for discharging the heated medium an outlet connection 19 is arranged on the housing 10.

Um einen optimalen Wärmeübergang zu gewährleisten, ist die Wicklung 17 unter unmittelbarer Anlage an bzw. Berührung mit dem innenliegenden Rohrabschnitt 11 montiert.In order to ensure optimal heat transfer, the winding is 17 in direct contact with or contact with the inner pipe section 11 mounted.
