Abstract

The bypass is mounted behind the collector of a lamellar heat exchanger and a flap with servo drive/motor whose width corresponds to the width of the collector or its cover plate is mounted directly behind the heat exchanger on the frame or drip separator. The servo motor is designed so that it opens the flap when the outside temperature is lower than the cooler temperature so that only a partial amount of air flows through the cooler which reduces pressure losses and saves energy.

Description

Lamellenwärmetauscher in Lüftungszentralgeräten, insbesondere Kühler oder WRG-Systeme haben hohe luftseitige Widerstände, die mit Energie überwunden werden müssen, damit die gewünschte Luftmenge ankommt. Solange der Wärmetauscher diese Luft thermisch behandelt, ist dieser Widerstand nötig. Wenn aber nachts, im Winter, Frühjahr oder Herbst eine Kühlung nicht nötig ist, da die Außentemperatur unter der Kühltemperatur liegt, ist dieser Widerstand technisch ein großer Nachteil und verursacht hohe Kosten an Ventilatorstromverbrauch.Finned heat exchanger in central ventilation units, in particular cooler or have heat recovery systems high air-side resistances, overcome with energy Need to become, thus the desired amount of air arrives. As long as the heat exchanger this Air thermally treated, this resistance is needed. If but at night, in winter, spring or fall a cooling not necessary is because the outside temperature below the cooling temperature This resistance is technically a big disadvantage and causes high cost of fan power consumption.

Lösung:Solution:

Unmittelbar hinter dem Wärmetauscher, am Wärmetauscher-Rahmen oder Tropfenabscheider befestigt, wird eine Klappe mit Stellantrieb montiert, deren Breite der des Sammlers bzw. des Abdeckbleches des Sammlers entspricht. Dadurch wird die Kühlerfläche nicht zusätzlich reduziert, sondern nur der Platz ausgenutzt, der vorher durch ein Blech abgedeckt war. Im geschlossenen Zustand wirkt die Klappe wie das bisherige Abdeckblech abdichtend. Wenn aber der Kühler nicht benötigt wird, da die Außentemperatur unterhalb der Kühlertemperatur liegt, öffnet der Stellmotor die Klappe und ein Teil der Gesamtluftmenge wird am Lamellenpaket vorbei geleitet. Dadurch verringert sich der Druckverlust am Gesamttauscher erheblich (bis zu 30 %). Da ein Kühler meist nur wenige Stunden im Jahr betrieben wird, die Lüftungsanlage aber diesen Widerstand immer überwinden muss, ist dieser Bypass im Betrieb eine Investition, die sich schon nach wenigen Tagen des Betriebes rechnen kann.immediate behind the heat exchanger, on the heat exchanger frame or mist eliminator attached, will be a flap with actuator mounted, the width of the collector or the cover plate of the Corresponds to collector. As a result, the radiator surface is not additionally reduced, but only the space exploited, previously covered by a sheet was. When closed, the flap acts like the previous one Cover plate sealing. But if the cooler is not needed, because the outside temperature below the cooler temperature lies, opens the servomotor is the flap and part of the total amount of air led past the disk pack. This reduces the pressure loss at the total exchanger considerably (up to 30%). As a cooler mostly is operated only a few hours a year, the ventilation system but this resistance always overcome must, this bypass in operation is an investment that is already after a few days of operation can count.

Vorteil:Advantage:

  • – Bypass schränkt nicht den freien Wärmetauscher-Querschnitt ein!- Bypass restricts not the free heat exchanger cross section one!
  • – Betriebskosten der Lüftungsanlage werden je nach Nutzung und Betriebsdauer gesenkt.- Operating cost the ventilation system are lowered depending on usage and operating time.

Bypass hinter dem Sammler eines Lamellenwärmetauschers, dadurch gekennzeichnet, dass unmittelbar hinter dem Wärmetauscher am Wärmetauscher-Rahmen oder Tropfenabscheider eine Klappe mit Stellantrieb-/motor montiert ist, deren Breite der des Sammlers bzw. Abdeckblechs des Sammlers entspricht.Bypass behind the collector of a finned heat exchanger, characterized in that immediately behind the heat exchanger on the heat exchanger frame or mist eliminator valve with Stellantrieb- / motor is mounted, whose width corresponds to that of the collector or cover plate of the collector. Bypass nach vorgenannten Anspruch, dadurch gekennzeichnet, dass der Stellmotor so ausgelegt ist, dass er bei einer niedrigeren Außentemperatur als der Kühlertemperatur die Stellklappe öffnet und somit der Kühler nur mit einer Teilluftmenge durchströmt wird, was den Druckverlust verringert und Energie spart."Bypass according to the preceding claim, characterized that the servomotor is designed so that it at a lower outside temperature as the cooler temperature the butterfly valve opens and thus the cooler flows through only a partial amount of air, which is the pressure loss reduces and saves energy.
