Stand der TechnikState of the art

Das konventionelle Verfahren der Zu-Ablüftung, d. h. der Austausch von warmer Luft gegen kalte Frischluft/Außenluft reicht in der Regel nicht aus, um die großen anfallenden Wärmemengen abzuführen. Unter Zuhilfenahme von Kälte, welche mittels Kältemaschinen erzeugt wird, wird die Außenluft weiter abgekühlt und mit einer niedrigeren Temperatur in den thermisch hochbelasteten Raum eingebracht. Insbesondere in den warmen Monaten muß eine große Kühlleistung durch die Kälteerzeuger bereitgestellt werden, um die erforderliche geringe Einblastemperatur zu gewährleisten. The conventional process of exhaust ventilation, d. H. the exchange of warm air for cold Fresh air / outside air is usually sufficient not out to the large amounts of heat dissipate. With the help of cold, which is generated by chillers, the outside air is cooled further and with a lower temperature in the thermal highly loaded space. In particular in the warm months a great cooling capacity is required provided by the refrigerators to the required low Ensure blowing temperature.  

Kältemaschinen arbeiten mit einem hohen Energiebedarf. Um große Luftmengen auf ein niedrigeres Temperaturniveau zu bringen, sind große Kompressoren erforderlich. Dieses bedeutet große Anschlußleistungen und hohe Betriebsgrundkosten.Chillers work with a high energy requirement. For large amounts of air to a lower one Bring temperature level are large compressors required. This means high connected loads and high Basic operating costs.

Verschiedene Produktionsprozesse, auch Anlagen mit großer Wärmeabstrahlung, wie Schaltzentralen, Computerräume etc. haben eine hohe thermische Abstrahlung; diese anfallende Wärme erwärmt den Raum/die Luft. Diese Luft wird dann durch kältere Außenluft ersetzt, sofern ein ausreichendes -vorhanden ist und diese Luftmenge ohne Störung der Produktion bzw. des Funktionsablaufes (Zugerscheinungen) eingebracht werden kann. Ist kein ausreichendes t vorhanden, wird die Frischluft/Außenluft durch große Kälteapparate/-maschinen gekühlt. Die direkte Kühlung durch Außenluft erlaubt kein gleichmäßiges Raumklima, sofern die Luft nicht zusätzlich aufbereitet wird. Um annähernd gleichmäßige Zustandswerte und gleiche Luftreinheit zu erreichen, sind aufwendige Apparaturen erforderlich, welche sich wieder in der Energiebilanz und in den Betriebskosten niederschlagen.Various production processes, including plants with high heat radiation, such as control centers, Computer rooms etc. have a high thermal Radiation; this heat warms the room / air. This air will then replaced by colder outside air, provided there is sufficient - and this Air volume without disrupting production or Functional sequence (drafts) introduced can be. Is not enough t available, the fresh air / outside air cooled by large refrigeration machines. Direct cooling by outside air allowed no uniform indoor climate, provided the air is not processed in addition. To almost uniform state values and same Achieving air purity is complex Apparatus required, which is again in energy balance and operating costs knock down.

Der heutige Lebensstandard wurde durch die Nutzbarmachung von billigen, fossilen Energieträgern erreicht. Da die Energie überaus billig war, wurde diese oftmals sinnlos verpraßt. Im Zuge der stetigen Verteuerung der Energie erfolgte ein Umdenken im Energieverbrauch. Einhergehend mit dem Energieverbrauch erfolgte eine Zerstörung der Umwelt durch riesigen Tageabbau, durch Schadstoffausstoß. Durch den zunehmenden Wärmeeintrag und durch den Ausstoß von Schadstoffen in die Erdatmosphäre erfolgt eine Klimaveränderung und ein zunehmendes Gesundheitsrisiko. Unter Berücksichtigung dieser Faktoren kann eine Zielsetzung nur heißen: Energieeinsparung, Energierückgewinnung, Reduzierung der Anschlußleistungen - Substitution der fossilen Energieträger.Today 's standard of living was influenced by Harnessing cheap, fossil fuels reached. Because the energy is extremely was cheap, it was often wasted senselessly. In the course of the constant increase in the price of the Energy was rethinking energy consumption. Along with the energy consumption the environment was destroyed huge daily mining, through pollutant emissions. Due to the increasing heat input and the emission of pollutants into the earth's atmosphere there is a climate change and a increasing health risk. Considering of these factors can be an objective only mean: energy saving, energy recovery, Reduction of connected loads - Substitution of fossil fuels.

KonstruktionsmerkmaleDesign features

Das Gerät enthält einen oder mehrere Einfach- oder Mehrfachwärmetauscher. Dieser Wärmetauscher kann alleine als Rekuperator betrieben werden oder mit einem Wasserberieselungssystem in die einströmende Außenluft. Hierdurch erfolgt eine direkte Abkühlung der Außenluft, durch die Wasserverdunstung erfolgt eine weitere Abkühlung der Luft (Prinzip der addiabatischen Kühlung). Mittels Ventilatoren wird die so gekühlte Luft auf dem "externen" Weg durch den Wärmetauscher gefördert. Im Gegenstrom hierzu wird im "internen" Weg die zu kühlende Raumluft gefördert. Beide Luftwege sind hermetisch getrennt, dadurch ist eine Luftmischung in der Standardbaureihe nicht möglich. Durch Zuschaltung einer Kältemaschine, eines Kühlregisters oder sonstigen Kälteeinrichtung in den Zuluftstrom des "externen" Weges erfolgt eine weitere Abkühlung der einströmenden Luft in den "externen" Weg. Durch die addiabatische Kühlung wird keine große Luftvorkühlung erreicht. Die zu installierende Kältemaschine hat i.d.R. bei diesem Prinzip nur noch einen Anschlußwert von ca. 30% einer vergleichbaren konventionellen Klimaanlage für thermisch hochbelastete Räume. The device contains one or more single or multiple heat exchangers. This heat exchanger can be operated alone as a recuperator or with a water sprinkler system in the incoming outside air. This results in a direct cooling of the outside air through which Evaporation of water is followed by a further cooling the air (principle of addiabatic Cooling). This is done with fans cooled air on the "external" way through the Heat exchangers promoted. In countercurrent to this becomes the indoor air to be cooled in the "internal" way promoted. Both airways are hermetic separated, this creates an air mixture in the Standard series not possible. By activation a chiller, a cooling register or other cooling device in the supply air flow of the "external" path takes place further cooling of the inflowing air in the "external" way. Through the addiabatic Cooling does not achieve large air pre-cooling. The chiller to be installed usually has with this principle only one Connection value of approx. 30% of a comparable one conventional air conditioning for thermal heavily used rooms.  

Die Anlage kann mit jedem Kühlsystem einzeln oder mit den anderen in Kombination betrieben werden.The system can be used with each cooling system individually or operated in combination with the others will.

Addiabatische KühlungAddiabatic cooling

Das Prinzip der addiabatischen Kühlung ist seit langer Zeit bekannt und beruht auf der Verdunstung von Wasser. Dieses Kühlverfahren wird vielfach für Industrieklima in Textilbetrieben erfolgreich zur Kühlung der Zuluft bei gleichzeitiger Befeuchtung eingesetzt. Im Bereich der Komfort-Klimaanlagen ist jedoch eine Kühlung durch Befeuchtung unakzeptabel, da sich hierdurch die Behaglichkeit nicht verbessert. Durch die konstruktive Vereinigung dieses Verfahrens mit dem Einfach- oder Mehrfach- Kreuzstromwärmetauscher und das Zusammenfügen dieser Elemente zu einer Kompakteinheit einschließlich einer integrierten Steuerungs- und Regelanlage wurde es möglich, dieses Verfahren auf großer Breite anzuwenden und kostengünstig eine Zuluftkühlung und -trocknung zu erreichen unter weitgehendem Verzicht auf FCKW-Kältemittel bei gleichzeitiger bedeutender Einsparung an elektrischer Energie im Vergleich zu Anlagen herkömmlicher Art.The principle of addiabatic cooling is has been known for a long time and is based on the Evaporation of water. This cooling process is often used for industrial climates in textile companies successful for cooling the supply air used with simultaneous humidification. in the The area of comfort air conditioning is however cooling by humidification is unacceptable, since this does not change the comfort improved. Through the constructive union this procedure with the single or multiple Cross flow heat exchanger and assembling of these elements into a compact unit including an integrated control and Control system it became possible to use this procedure Can be used over a wide range and inexpensively to achieve supply air cooling and drying largely avoiding CFC refrigerants with significant savings at the same time of electrical energy compared to Conventional systems.
