Description
Die Erfindung bezieht sich zunächst auf ein Verfahren gemäß dem Oberbegriff der unabhängigen Verfahrensansprüche.The invention initially relates to a method according to the preamble of the independent method claims.
In Adsorptionswärmepumpen werden eine Wärmequelle im Gerät, oft ein konventioneller Brenner, und eine Umweltwärmequelle genutzt, um einen Heizkreislauf zu beheizen. Die Umweltwärmequelle wird genutzt, um in einem Verdampfer Kältemittel zu verdampfen, das in einem Adsorber adsorbiert, wodurch Adsorptionswärme freigesetzt wird. Diese Wärme geht auf einen Wärmeträger in einem Primärkreislauf über. Der Wärmeträger wird anschließend von der Wärmequelle im Gerät weiter erhitzt und gelangt in einen Desorber. In dem Desorber wird Wärmeenergie dazu benötigt, um Kältemittel zu desorbieren. Das Kältemittel kondensiert an einem Kondensator und gibt dabei Wärme ab. Diese Wärme ist für den Heizkreislauf bestimmt. Der Wärmeträger des Primärkreislaufs gibt nach Verlassen des Desorbers einen Teil seiner Wärme an den Heizkreislauf, um dann wieder in den Adsorber zu strömen.In adsorption heat pumps, a heat source in the device, often a conventional burner, and an environmental heat source are used to heat a heating circuit. The environmental heat source is used to evaporate refrigerant in an evaporator, which adsorbs in an adsorber, thereby releasing heat of adsorption. This heat is transferred to a heat transfer medium in a primary circuit. The heat transfer medium is then further heated by the heat source in the device and enters a desorber. In the desorber, heat energy is needed to desorb refrigerant. The refrigerant condenses on a condenser, releasing heat. This heat is intended for the heating circuit. After leaving the desorber, the heat transfer medium of the primary circuit supplies part of its heat to the heating circuit, in order then to flow back into the adsorber.
Der Adsorptions- und Desorptionsprozess findet in der Regel bei Temperaturen zwischen 150 und 200°C statt. Die Umweltwärmequelle sollte eine Temperatur von -10°C nicht unterschreiten, da ansonsten kein oder kaum Kältemittel im Verdampfer verdampft werden kann. In diesem Fall schalten Adsorptionswärmepumpen gemäß dem Stand der Technik ab. Um Wohnraum an solch kalten Tagen zu beheizen, wird dann eine zusätzliche Wärmequelle benötigt.The adsorption and desorption process usually takes place at temperatures between 150 and 200 ° C. The environmental heat source should not fall below a temperature of -10 ° C, otherwise no or hardly any refrigerant can be vaporized in the evaporator. In this case, adsorption heat pumps switch off according to the prior art. In order to heat living space on such cold days, an additional heat source is needed.

Ziel der Erfindung ist es, diesen Nachteile zu vermeiden und ein Verfahren der eingangs erwähnten Art vorzuschlagen, bei dem auch ohne Umweltwärmequelle mit Hilfe einer Adsorptionswärmepumpe geheizt werden kann.The aim of the invention is to avoid these disadvantages and to propose a method of the type mentioned in which it is possible to heat without the use of an adsorption heat pump even without an environmental heat source.
Erfindungsgemäß wird dies bei einem Verfahren der eingangs erwähnten Art durch die kennzeichnenden Merkmale des unabhängigen Verfahrensanspruches erreicht.According to the invention this is achieved in a method of the type mentioned by the characterizing features of the independent method claim.
Durch die vorgeschlagenen Maßnahmen wird erreicht, dass die Anlage auch ohne Wärmepumpen-Module betrieben werden kann. Hierzu befinden sich Bypassleitungen parallel zu den Wärmepumpenmodulen. Werden die darin befindlichen Absperrorgane geöffnet, so kann der Wärmeträger durch die Bypassleitungen, die einen geringeren Strömungswiderstand haben als die Wärmepumpen-Module, strömen. Die Wärmepumpen-Module können auch teildurchströmt werden, wodurch auch kleine Umweltwärmemengen bei hoher Heizleistung eingebracht werden kann.The proposed measures ensures that the system can be operated without heat pump modules. For this purpose, bypass lines are located parallel to the heat pump modules. If the shut-off devices located therein are opened, the heat transfer medium can flow through the bypass lines, which have a lower flow resistance than the heat pump modules. The heat pump modules can also be partially flowed through, which also small amounts of ambient heat can be introduced at high heat output.
Gemäß den kennzeichnenden Merkmalen des Anspruchs 2 wird der gleiche Effekt auch dadurch erzielt, dass Umschaltorgane eine Durchströmung der Bypassleitungen anstelle der Wärmepumpen-Module ermöglicht.According to the characterizing features of
Gemäß den Merkmalen des Anspruchs 3 wird ein sinnvolles Kriterium für die Veränderung der Durchströmung beschrieben.According to the features of claim 3, a meaningful criterion for the change of the flow is described.
Gemäß den Merkmalen des Anspruchs 4 ergibt sich der Vorteil, dass der Wärmeträger nicht mehr nur auf die für den Adsorber und Desorber notwendige Arbeitstemperatur aufgeheizt werden darf. Stattdessen kann der Wärmeträger auf bei konventionellen Heizgeräten übliche Temperaturen aufgeheizt werden. Dies kann man dadurch erreichen, indem die Strömungsgeschwindigkeit vermindert wird. Dies wiederum erreicht man am einfachsten durch eine Reduzierung der Pumpendrehzahl.According to the features of claim 4, there is the advantage that the heat transfer medium must not be heated only to the necessary for the adsorber and desorber operating temperature. Instead, the heat carrier can be heated to conventional temperatures in conventional heaters. This can be achieved by reducing the flow rate. This is most easily achieved by reducing the pump speed.
