Abstract

The invention relates to a heat pump for room heating with hot water, without additional external heat. The mode of working of the heat pump is adequately known, see inter alia "Lueger Encyclopaedia of Technology, Volume 7 - Lexicon of energy technology and engines", in which the "left"-running Carnot cycle is described in detail, according to which the heating medium - hot water - is raised from a lower temperature to a higher one by a compression and expansion process with the aid of supplied energy. Normally, in this process, the heat contained in an available heat carrier, such as ambient air, ground heat or groundwater, is extracted and the heating medium - hot water - is brought to a higher temperature level. The performance number in these installations is between 2 and 3. Only with great technical power expenditure would it be possible to bridge a high temperature difference between an available heat carrier and the desired delivery temperature without reducing the performance number. The invention of the application is intended to avoid the abovementioned disadvantages and at the same time considerably reduce the technical outlay and the installation costs. Mode of operation: when the room temperature falls below a set value, the starting heating (5) is switched on via a room thermostat, the operating medium, e.g. Freon 12, is heated, drawn in by the compressor (1) which is now switched on and pressed into the liquefier (4). In this case, the operating medium which is now energetically charged delivers energy in the form of heat to the hot-water heating system during expansion (outlet from the expansion valve). At the same time, via a pipe coil in the liquefier, which is connected to an identical one (6) in the evaporator, the operating medium is kept at a temperature around 10 DEG C. As the performance number depends on the temperature gap between heat source and heat consumer, it will not become smaller even in the case of low outside temperatures. The compression which is controlled by the forward-run temperature is achieved via the thyristor-controlled motor or compressor. The aim is thus achieved of operating the heat-pump installation economically with a compact installation without calling on a separate external heat for the evaporator. <IMAGE>

Die Wärmepumpe arbeitet bekanntlich nach dem Carnot1sehen Kreisprozeß,bei dem die bei der höheren Temperatur abgebene Wärmemenge Q., maßgebend ist.As is known, the heat pump works according to the Carnot 1 cycle process, in which the amount of heat Q., which is emitted at the higher temperature, is decisive.

Der thermische Wirkungsgrad(auch Carnot'scher Wirkungsgrad genannt) lautet: ·The thermal efficiency (also Carnot's efficiency called) reads:

T-T 'T-T '

Q1 T1 Q 1 T 1

Hierbei sind T... = höhere Temperatur , T„ = tiefere Temperatur Q* = Wärmemenge der hqheren TemperaturHere T ... = higher temperature, T "= lower temperature Q * = amount of heat at the higher temperature

Q2 = Q1 - AQ 2 = Q 1 - A

Der Ausdruck 1//>»wird auch als Leistungsziffer £. angegeben, sie liegt im allgemeinen bei technischen Anlagen zwischen 2 bis 3 . ;■■ The expression 1 //> »is also used as a performance figure £. indicated, it is generally between 2 and 3 for technical systems. ; ■■

Bei dem Verbrauch einer elektrischen Arbeit A z.B. wird eine Wärmemenge Q^ erzeugt,die TI/T^-T» , größer ist,als das entsprechende Wärmeäquivalent der Arbeit,welches bei einer direkten Widerstandsheizung gewonnen wurde(s.hierzu die einschlägige technische Literatur). "For example, when electrical work A is consumed, a Amount of heat Q ^ generated, which TI / T ^ -T », is greater than that corresponding heat equivalent of the work, which at a direct resistance heating was obtained (see the relevant technical literature). "

Der Verflüssiger oder Kondensator in dem das Betriebsmittel unter Abgabe des größten Teils der in ihm enthaltenen Wärme (bestehend aus der Verdampfungswärme und der mechanisch zugeführten Energie) verflüssigt wird,ist als Wärmeaustauscher ausgeführt. The condenser or condenser in which the equipment with the release of most of the heat contained in it (consisting of the heat of vaporization and the mechanically supplied Energy) is liquefied, is designed as a heat exchanger.

Der Wärmeaustauscher gibt diese Wärmeenergie an den Wärmeträger (Wasser oder Luft) der Heizungsanlage ab.The heat exchanger transfers this thermal energy to the heat transfer medium (water or air) of the heating system.

Aus wirtschaftlichen Gründen sollte die Temperatur des Wärmeträgers möglichst niedrig gehalten werden,also sollten großflächige Heizungen,wie Decken- oder Wandheizungen den normalen Radiatoren vorgezogen werden.For economic reasons, the temperature of the heat carrier should should be kept as low as possible, so large areas should be Heaters such as ceiling or wall heating are preferred to normal radiators.

Die Wärmepumpe muß für die infrage kommenden Außentemperaturen von - 2o°C bis + 18°C und für die Vorlauftemperaturen von + 5o°C bis 4 240C ausgelegt sein.
Das entspricht einer Differenz von 7oK bis 6K. Die maximale Temperaturdifferenz wird jedoch nur selten erreicht werden.The heat pump has for the candidate outside temperatures of - be designed 2o ° C to + 18 ° C and the flow temperature of + 5o ° C to 4 24 0 C.
This corresponds to a difference of 7oK to 6K. However, the maximum temperature difference will only rarely be reached.

Die Erfindung sieht ihre Aufgabe darin,eine Heizungsanlage mit einer Wärmepumpe so zu gestalten,daß die Gesamtanlage (Bau- und Installationskosten sowie Betriebskosten)wirtschaftlich arbeitet.The object of the invention is to provide a heating system to design with a heat pump in such a way that the entire system (construction and installation costs as well as operating costs) is economical is working.

Die erfindungsgemäße Heizungsanlage ist dadurch gekennzeichnet, daß keine Fremdwärme für den Arbeitsablauf der Wärmepumpe vorgesehen ist,abgesehen von einer kleinen Zusatzheizung,die nur kurzzeitig zum Anfahren der Anlage benutzt und dann abgeschaltet wird.The heating system according to the invention is characterized by that no external heat is provided for the work flow of the heat pump, apart from a small additional heater that is only used briefly to start up the system and then switched off.

(7) die Thyristorsteuerung des Verdichters (8) Temperaturregler (9) Warmwasserheizung dazu(7) the thyristor control of the compressor (8) temperature controller (9) Hot water heating in addition

Die Arbeitsweise der Erfindung geht folgendermaßen vor sich: Sinkt die Raumtemperatur unter einen eingestellten Wert,z.B. j- 18°C, dann wird die Anfahrheizung (5) über einen Raumthermostaten eingeschaltet,das Betriebsmittel Frigen oder Ammoniak wird erwärmt und vom Verdichter (1) angesaugt und in den Verflüssiger (4) gedrückt.The invention works as follows: If the room temperature falls below a set value, e.g. j- 18 ° C, then the start-up heating (5) is switched on via a room thermostat switched on, the refrigerant or ammonia is heated and sucked in by the compressor (1) and into the condenser (4) pressed.

Hat nun die Vorlauftemperatur einen bestimmten Wert erreicht, wird über einen Thermostaten die Anfahrheizung abgeschaltet. Über einen von der Vorlauftemperatur gesteuerten Regler (8) wird der Elektromotor M des Verdichters (1) durch eine Thyristor steuerung beaufschlagt. Hiermit soll die Drehzahl des Motors in weiten Grenzen und damit auch die Verdichtung reguliert werden,um einen intermittierenden Betrieb des Motors zu vermeiden. If the flow temperature has now reached a certain value, the start-up heating is switched off via a thermostat. Via a controller (8) controlled by the flow temperature the electric motor M of the compressor (1) is acted upon by a thyristor control. This is the speed of the engine can be regulated within wide limits and thus also the compression in order to avoid intermittent operation of the engine.
