Description
Luftheizung mit Umlauf der Luft in geschlossener Leitung: Gegenstand der Erfindung ist eine Vorrichtung zur selbsttätigen Ausgleichung des Druckes in einer geschlossenen Luftheizungsanlage, durch welche bewirkt wird, daß, bei Unterdruck nur Frischluft in die Anlage eintreten, bei Überdruck erwärmte reine Luft nur in die zu beheizenden Räume austreten kann. Die Leitung b führt die im Lufterhitzer a erwärmte Luft nach den Heizkörpern d; aus diesen fließt die abgekühlte Luft in der Leitung e zum Lufterhitzer zurück. In die im übrigen geschlossene Luftleitung ist mindestens in einem der zu beheizenden Räume ein Rückschlagventil c so eingebracht, daß nur Luft aus der Leitung aus-, aber keine kaumluft in die Leitung einströmen kann (Abb. a). In der vom Heizkörper d absteigenden Leitung.e ist kurz vor' Eintritt derselben in den Erhitzer a ein . anderes Rückschlagventil fangeordnet, das sich nur dem Druck von außen öffnet und nur Frischluft aus einer aus dem Freien kommenden Zuleitung eintreten läßt (Abb. t).Air heating with circulation of the air in a closed line: The subject of the invention is a device for the automatic equalization of the pressure in a closed air heating system, which causes only fresh air to enter the system when the pressure is negative, and pure air that is heated when the pressure is too high heating rooms can escape. The line b leads the air heated in the air heater a to the radiators d; from these the cooled air flows back to the air heater in line e. In the otherwise closed air line, a check valve c is inserted in at least one of the rooms to be heated in such a way that only air can flow out of the line, but no air can flow into the line (Fig. A). In the line.e descending from the radiator d, there is a just before it enters the heater a. Another non-return valve is arranged, which opens only to pressure from the outside and only allows fresh air to enter from a supply line coming from the open (Fig. t).
Bei Überdruck öffnet sich also das in den Räumen angebrachte Ventil c, während sich das Zuführungsventil f vor dem Heizkessel schließt. Somit kann die überschüssige und bereits erwärmte Luft nur in die Räume, nicht ins Freie entweichen. Wärmeverlust infolge von Ausdehnung ist also unmöglich.In the event of overpressure, the valve installed in the rooms opens c, while the supply valve f closes in front of the boiler. Thus, the Excess and already heated air can only escape into the rooms, not into the open air. So heat loss due to expansion is impossible.
Bei Unterdruck schließt sich das Abflußventil c im zu beheizenden Raume und öffnet sich das Zuflußventil f vor dem Kessel. Es kann also nur Frischluft eintreten, während der verbrauchten Zimmerluft das Einströmen verwehrt ist. Ob für den Fall wechselnder Benutzung von Räamen in mehreren derselben Abflußventile anzubringen sind, ferner, ob diese Ventile bis auf eins, das als Sicherheitsventil stets druckempfindlich bleiben muß, absperrbar einzurichten sind, muß im Einzelfalle je nach Bedarf entschieden werden.When there is negative pressure, the drain valve c closes in the to be heated Room and opens the inflow valve f in front of the boiler. So it can only get fresh air enter while the stale room air is prevented from flowing in. Whether for to place the case of alternating use of rooms in several of the same drainage valves are, furthermore, whether these valves are always pressure-sensitive except for one, the safety valve must remain, must be set up in a lockable manner, must be decided on a case-by-case basis as required will.
Die Ventile treten nicht nur beim Anheizen und beim Stillsetzen der Anlage in Tätigkeit, sondern auch während des Heizens, da durch stärkere oder schwächere Abkühlung der Heizkörper und infolge stärkeren oder schwächeren Befeuerns des Lufterhitzers häufig Volumenänderungen der Heizluft eintreten.The valves not only come into play when heating up and when the Plant in activity, but also during heating, as by stronger or weaker Cooling of the radiators and as a result of stronger or weaker firing of the air heater frequent changes in the volume of the heating air occur.
