Description
Die Erfindung betrifft eine wärmetechnische Anlage, insbe-sondere einer Kälteanlage.The invention relates to a thermal system, in particular a refrigeration system.
Der Bedarf an Klimatisierungsaufwand, insbesondere Kälteenergie, und somit der Gesamtenergiebedarf aufgrund steigender Arbeitsplatzanforderungen und Komfortwünsche ist stetig stark steigend. Die Klimatisierung der privaten wie gewerblichen Fahrzeugtechnik bezogen auf die Fahrgastzelle hat innerhalb von 10 Jahren von einem marginalen Marktanteil annähernd 100 % erreicht. Ähnliches ist für die Klimatisierung des Gebäudebestands zu erwarten. Zusätzlich wird mit Umsetzung der europäischen Richtlinie über die Gesamtenergieeffizienz von Gebäuden künftig der Kühlenenergiebedarf bei der Gebäudebewertung berücksichtigt. Energie- und kosteneffiziente Kühltechnologien gewinnen hierdurch weiter an Bedeutung.The need for air conditioning, especially cooling energy, and thus the total energy requirement due to increasing workplace requirements and comfort requirements is constantly increasing. The air conditioning of private and commercial vehicle technology in relation to the passenger compartment has almost 100% of a marginal market share within 10 years. The same can be expected for the air conditioning of the building stock. In addition, with the implementation of the European directive on the overall energy efficiency of buildings, the cooling energy requirement will be taken into account in the building assessment. As a result, energy and cost-efficient cooling technologies continue to gain in importance.
Ein Hemmnis für den verstärkten Ausbau kapitalintensiver KWK-Technologien (KWK - Kraft-Wärme-Kopplung) ist die geringe Systemauslastung in den Sommermonaten. Die umweltschonende Kältebereitstellung mittels thermischer Kälteerzeugungsprozesse gilt als Möglichkeit, diesem Hemmnis entgegen zu wirken. Gerade in Fernwärmenetzen, die vorwiegend durch KWK-System versorgt werden, steht die notwendige Wärmeenergie zum Betrieb von thermischen Kälteerzeugungsprozessen als Abwärme aus der Stromerzeugung zur Verfügung.An obstacle to the increased expansion of capital-intensive CHP technologies (CHP - combined heat and power) is the low system utilization in the summer months. The environmentally friendly provision of refrigeration by means of thermal refrigeration processes is seen as an opportunity to counteract this obstacle. In district heating networks in particular, which are mainly supplied by a CHP system, the heat energy required to operate thermal cooling processes is available as waste heat from electricity generation.
Die Hauptkomponenten von Kälteanlagen wie Verdampfer, Absorber, Austreiber und Kondensator sind Wärmetauscher, die alle zwischen Medienwärme transportieren. Diese Wärmeüberträger sind hierbei für 50 % der Kosten und 75 % des Volumens der Kälteanlage verantwortlich.The main components of refrigeration systems such as evaporators, absorbers, expellers and condensers are heat exchangers, which all transport between media heat. These heat exchangers are responsible for 50% of the costs and 75% of the volume of the refrigeration system.

Aufgabe der Erfindung ist es eine wärmetechnische Anlage mit einem verbesserten konstruktiven Aufbau zu schaffen, der den flexiblen Einsatz der wärmetechnischen Anlage in Anwendungen mit unterschiedlichen Anforderungen unterstützt.The object of the invention is to provide a thermal system with an improved structural design that supports the flexible use of the thermal system in applications with different requirements.
Diese Aufgabe wird erfindungsgemäß durch eine wärmetechnische Anlage nach dem unabhängigen Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von abhängigen Unteransprüchen.This object is achieved according to the invention by a thermal system according to independent claim 1. Advantageous embodiments of the invention are the subject of dependent subclaims.
Wärmeübertrager bekannter Art wurden bisher individuell und unabhängig voneinander an die erforderlichen Leistungen angepasst. Die mit der Erfindung neu geschaffene Einheit besteht aus einem oder mehreren Paaren aus Verdampfereinrichtung und Verflüssigereinrichtung, welche eine thermodynamische und prozesstechnische Einheit bilden. Diese thermodynamische Einheit ist insbesondere dadurch gekennzeichnet, dass sowohl die Länge des Dampfweges als auch der spezifische Dampfmassenstrom unabhängig von der absoluten Leistung bzw. Kapazität der gesamten Wärmeübertragereinheit. Das einmal optimierte Verhältnis der Kapazitäten der Wärmeübertrager untereinander, welche eine übergeordnete Einheit bilden, bleibt selbst bei Skalierungen der Leistung erhalten.Up to now, heat exchangers of a known type have been individually and independently adapted to the required outputs. The unit newly created with the invention consists of one or more pairs of evaporator device and condenser device, which form a thermodynamic and process engineering unit. This thermodynamic unit is characterized in particular in that both the length of the steam path and the specific steam mass flow are independent of the absolute power or capacity of the entire heat exchanger unit. The once optimized ratio of the capacities of the heat exchangers to one another, which form a higher-level unit, is retained even when the output is scaled.
Es können modulartige Wärmetauschereinheiten hergestellt werden, die in einer Gesamtanlage zusammensetzbar sind, wodurch eine verbesserte Skalierbarkeit von wärmetechnischen Anlagen oder Wärmepumpen, insbesondere Kälteanlagen und Entsalzungsanlagen, ermöglicht ist. Die stirnseitige Konfiguration ermöglicht darüber hinaus einen konstruktiven Aufbau mit optimierter Raumausnutzung und trägt entscheidend zur thermischen Trennung der unterschiedlichen Funktionseinheiten, Dampferzeuger und Verflüssiger bei, wodurch trotz räumlicher Optimierung die thermischen Verluste minimiert werden.Modular heat exchanger units can be produced, which can be assembled in an overall system, which enables improved scalability of thermal engineering systems or heat pumps, in particular refrigeration systems and desalination systems. The front-side configuration also enables a structural design with optimized space utilization and makes a decisive contribution to the thermal separation of the different functional units, steam generators and condensers, which minimizes thermal losses despite spatial optimization.
Bei der Verdampfereinrichtung kann es sich zum Beispiel um einen Generator oder einen Verdampfer handeln. Die Verflüssigereinrichtung ist beispielsweise als ein Absorber oder ein Kondensator ausgeführt. Die stirnseitige Anordnung von Verdampfereinrichtung und Verflüssigereinrichtung führt im Vergleich zu bekannten Wärmetauschereinheiten zu einem veränderten Dampfströmungsverhalten zwischen den Einrichtungen, was eine Art Wellenbildung impliziert, wodurch ein erhöhter Wärme- und Stoffübergang erreicht ist. Die leistungsbezogene Wärmetauscherfläche ist verringert.The evaporator device can be, for example, a generator or an evaporator. The liquefier device is designed, for example, as an absorber or a condenser. The frontal arrangement of the evaporator device and the condenser device leads to a changed steam flow behavior between the devices compared to known heat exchanger units, which implies a kind of wave formation, whereby an increased heat and mass transfer is achieved. The performance-related heat exchanger area is reduced.
Die mit der Erfindung erreichte Skalierbarkeit ermöglicht es, wärmetechnische Anlagen, insbesondere Kälteanlagen, hinsichtlich der Anlagengröße und -leistung für unterschiedliche Anwendungen individuell anzupassen. Insbesondere ist eine kompakte Bauform ermöglicht, um in kleine Leistungsbereiche vorzustoßen, die für bekannte Bauarten des möglichen Zusammenbaus von Wärmetauscherkomponenten wegen schlechter Leistungsdichte und großem Platzbedarf unattraktiv waren.The scalability achieved with the invention makes it possible to individually adapt thermal engineering systems, in particular refrigeration systems, with regard to the system size and output for different applications. In particular, a compact design is made possible to advance into small performance ranges that were unattractive for known types of possible assembly of heat exchanger components due to poor power density and large space requirements.
Die Erfindung sieht vor, dass die Verdampfereinrichtung und die Verflüssigereinrichtung einander stirnseitig gegenüberstehend angeordnet sind. So sind Stirnflächen der Verdampferreinrichtung und der Verflüssigereinrichtung einander gegenüberliegend angeordnet, sei es in einem Abstand voneinander oder im Wesentlichen aufeinander liegend.The invention provides that the evaporator device and the condenser device are arranged opposite one another on the end face. For example, end faces of the evaporator device and the condenser device are arranged opposite one another, either at a distance from one another or essentially lying on top of one another.
Bei einer zweckmäßigen Ausgestaltung der Erfindung kann vorgesehen sein, dass die Verdampfereinrichtung und die Verflüssigereinrichtung wenigstens abschnittsweise stirnseitig ineinandergreifend angeordnet sind. Bei dieser Ausführungsform greifen Leitungsabschnitte von Verdampfereinrichtung und Verflüssigereinrichtung abschnittsweise ineinander, wobei eine hierdurch gebildete Überlappung vorzugsweise größer oder kleiner als die halbe Längserstreckung der jeweiligen Rohrleitungen ist.In an expedient embodiment of the invention it can be provided that the evaporator device and the liquefier device are arranged at least in sections interlocking at the end. In this embodiment, line sections of the evaporator device and the condenser device engage in sections, with an overlap formed thereby preferably being greater or less than half the longitudinal extent of the respective pipelines.
Eine vorteilhafte Ausführungsform der Erfindung sieht vor, dass Rohrleitungen der Verdampfereinrichtung und Rohrleitungen der Verflüssigereinrichtung alternierend ineinandergreifen. Abwechselnd sind eine Rohrleitung der Verdampfereinrichtung und eine Rohrleitung der Verflüssigereinrichtung angeordnet.An advantageous embodiment of the invention provides that pipes of the evaporator device and pipes of the condenser device alternately interlock. A pipe of the evaporator device and a pipe of the condenser device are arranged alternately.
Bevorzugt sieht eine Fortbildung der Erfindung vor, dass eine der Verflüssigereinrichtung zugewandte Stirnfläche der Verdampfereinrichtung im Wesentlichen vollständig überlappend mit einer der Verdampfereinrichtung zugewandten Stirnfläche der Verflüssigereinrichtung angeordnet ist und / oder umgekehrt. In einer Ausführungsform sind die stirnseitigen Flächen also im Wesentlichen deckungsgleich angeordnet.A further development of the invention preferably provides that an end face of the evaporator device facing the condenser device is arranged substantially completely overlapping with an end face of the condenser device facing the evaporator device and / or vice versa. In one embodiment, the end faces are arranged essentially congruently.
Eine vorteilhafte Ausgestaltung der Erfindung sieht eine tropfabscheiderfreie Ausbildung vor. Im Unterschied zu bekannten Wärmetauschereinheiten können Aufwand und Vorkehrungen für einen Tropfenabscheider eingespart werden.An advantageous embodiment of the invention provides a drip separator-free design. In contrast to known heat exchanger units, the effort and provisions for a droplet separator can be saved.
Eine Weiterbildung der Erfindung sieht eine dampfsperrenfreie und / oder eine tropfensperrenfreie Ausbildung vor. Hierdurch ist eine weitergehende Vereinfachung gebildet, die einen material- und kostensparenden Aufbau unterstützt.A further development of the invention provides a vapor barrier-free and / or a drip barrier-free training. This creates a further simplification, which supports a material and cost-saving structure.
Die Erfindung sieht einen Modulaufbau vor. Das vorgesehen Konstruktionsprinzip hinsichtlich der Anordnung von Verdampfereinrichtung und Verflüssigereinrichtung ermöglicht es in einer Ausführungsform, in dem jeweiligen Modul eigenständige Strömungseigenschaften für das Wärmetauscherbetriebsmittel auszubilden, die sich im Wesentlichen auch nicht ändern, wenn mehrere als Modul aufgebaute Wärmetauschereinheiten zusammengesetzt werden in einer Anlage.The invention provides a module structure. The proposed design principle with regard to the arrangement of the evaporator device and the condenser device makes it possible, in one embodiment, to design independent flow properties for the heat exchanger operating means in the respective module, which essentially do not change even if several heat exchanger units constructed as modules are assembled in one system.
Bei einer zweckmäßigen Ausgestaltung der Erfindung kann vorgesehen sein, dass die Verdampfereinrichtung und die Verflüssigereinrichtung in einem thermischen Verdichter gebildet sind. Beispielsweise ist der thermische Verdichter in eine Kälteanlage integriert.In an expedient embodiment of the invention it can be provided that the evaporator device and the condenser device are formed in a thermal compressor. For example, the thermal compressor is integrated in a refrigeration system.
