Abstract
Description
Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruches 1. Zum Erzielen seiner vollen Wirksamkeit muß jedem Heizkörper in einer Heizungsanlage ein ausreichender Heizmittelmassestrom zugeführt werden. Da in einer Heizungsanlage nicht in allen Strängen dieselben hydraulischen Verhältnisse vorliegen, ist nach der Installation bzw. vor der Inbetriebnahme ein hydraulischer Abgleich erforderlich. Unterbleibt dieser, dann werden die ungünstig angeordneten Heizkörper nicht ausreichend oder erst verspätet mit dem Wärmeträgerstrom versorgt. Das führt dann dazu, daß vorrangig die hydraulisch günstiger liegenden Heizkörper durchströmt werden und somit diese Räume bevorzugt beheizt werden. Die übrigen Räume werden nicht ausreichend oder erst nach der Versorgung der bevorzugten Räume beheizt, das heißt erst dann, wenn infolge einer Einzelraum reglung durch das Thermostatventil der Massestrom durch den betreffenden Heizkörper abgesperrt wird. Das hat nicht nur unbefriedigende Aufheizergebnisse zur Folge. Das Regelverhalten der ganzen Anlage wird auch ungünstiger. Durch den hydraulischen Abgleich soll eine Vergleichmäßigung der Strömung durch alle Heizkörper erzielt werden.The invention relates to a method according to the preamble of patent claim 1. To achieve its full effectiveness, each radiator must be in one A sufficient heating mass flow can be supplied to the heating system. There in a heating system does not have the same hydraulic conditions in all lines there is a hydraulic one after installation or before commissioning Matching required. If this is not done, then the unfavorably arranged ones Radiator insufficient or delayed with the heat transfer flow provided. This then leads to the hydraulically more favorable ones Radiators are flowed through and thus these rooms are preferably heated. The remaining rooms are not sufficient or only after the supply of the preferred rooms heated, that is, only if as a result of a single room regulation by the thermostatic valve the mass flow through the concerned Radiator is shut off. This not only has unsatisfactory heating results result. The control behavior of the entire system is also less favorable. The hydraulic balancing is intended to equalize the flow through all radiators are achieved.
Zu diesem Zweck wird bisher an allen Thermostatventilen nach Erfahrungs- oder Rechenwerten eine geeignete maximale Offenstellung eingestellt, die bei hydraulisch ungünstiger Lage des Heizkörpers größer ist als bei hydraulisch günstiger Lage. Diese Einstellung gilt dann als die maximale Offenstellung während des laufenden Regelbetriebes. For this purpose, all thermostatic valves are currently based on experience or Calculated values set a suitable maximum open position, the hydraulic unfavorable position of the radiator is greater than with hydraulically favorable position. This setting is then considered the maximum open position during the current Regular operation.
Ein solcher manueller Abgleich ist von den Kenntnissen des Monteurs abhängig, indem er die einzelnen Stränge hinsichtlich ihrer hydraulischen Eigenschaft abschätzt oder durchrechnet und dann die Einstellung der Thermostatventile vornimmt. Wegen des Aufwandes unterbleibt der Abgleich häufig, was dann die unterschiedlichsten Ergebnisse in den einzelnen Räumen und das ungünstige Regelverhalten zur Folge hat.Such a manual adjustment depends on the knowledge of the fitter, by assessing the individual strands in terms of their hydraulic properties or calculated and then makes the setting of the thermostatic valves. Because of the effort is often not compared, which is then the most varied Results in the individual rooms and the unfavorable control behavior Has.
Der Erfindung lag die Aufgabe zugrunde, ein einfaches Verfahren zum Erzielen eines hydraulischen Abgleichs zu schaffen, welcher von speziellen Fachkenntnissen unabhängig und automatisch durchzuführen ist. Dabei sollen optimale Ergebnisse erzielt werden.The invention was based, a simple method to achieve a task to create hydraulic balancing, which of special expertise is to be carried out independently and automatically. The aim is to achieve optimal results be achieved.
Das erfindungsgemäße Verfahren besteht in der Anwendung der im Kennzeichen des Patentanspruches 1 genannten Maßnahmen.The method according to the invention consists in the application of the Claim 1 measures mentioned.
Bei diesem Verfahren werden die Thermostatventile nicht mehr gemäß der Abschätzung oder Berechnung des Monteurs mehr oder weniger stark geöffnet und dieser Wert dann als maximale Offenstellung festgelegt. Sie werden vielmehr zunächst alle voll geöffnet. Je nach den hydraulischen Verhältnissen stellen sich jetzt in den einzelnen Räumen unterschiedliche Temperaturen ein, die in den meisten Räumen wegen ihrer günstigen Lage und der vollen Öffnung der Ventile über dem gewünschten Raum-Sollwert liegen werden. Nach einer Stabilisierungszeit werden dann in den höher aufgeheizten Räumen die Ventile so weit geschlossen, daß sich in allen Räumen die gewünschte gleichmäßige Solltemperatur einstellt. Die jetzt eingestellten Offenstellungen der Thermostatventile, die von Raum zu Raum deutlich variieren können, führen somit zu dem gewünschten hydraulischen Abgleich. Dieser Öffnungsgrad der einzelnen Thermostatventile wird dann bei ausreichender Größe als maximale Offenstellung für alle weiteren Regelaktivitäten in das zentrale Regelgerät eingegeben. Bei einem späteren Hochfahren der Anlage aus kaltem Zustand werden alle Thermostatventile nur bis zu dieser maximalen Offenstellung geöffnet. Da gleiche Verhältnisse vorliegen, werden alle Räume gleichmäßig mit Wärme versorgt. With this method, the thermostatic valves are no longer in accordance with the Assessment or calculation of the fitter more or less open and this value is then set as the maximum open position. Rather, they will initially all fully open. Depending on the hydraulic conditions arise different temperatures in the individual rooms, which in the most rooms because of their convenient location and the full opening of the valves will be above the desired room setpoint. After a stabilization period the valves are then closed so far in the higher heated rooms that the desired, uniform target temperature is set in all rooms. The now set open positions of the thermostatic valves, from room to room can vary significantly, thus lead to the desired hydraulic balancing. This degree of opening of the individual thermostatic valves is then sufficient Size as the maximum open position for all further control activities in the central Control device entered. When the system is started up later from cold All thermostatic valves are only in this condition up to this maximum open position open. Since the conditions are the same, all rooms are even with Heat supplied.
Es ist denkbar, daß bei der Durchführung des Verfahrens nach dem völligen Öffnen und anschließenden teilweisen Drosseln einiger Thermostatventile bei allen Ventilen ein sehr geringer Öffnungsstellung dem Zentralgerät gemeldet wird. Das ist ein Indiz dafür, daß bei diesem Test die Vorlauftemperatur zu hoch lag. Jetzt wird zunächst die Vorlauftemperatur abgesenkt und der komplette Verfahrensablauf wiederholt. Die Öffnungsstellung ist jetzt größer, so daß diese maximale Offenstellung dem zentralen Gerät als maximale Stellung für die weitere Regelaktivität eingegeben wird.It is conceivable that when carrying out the method after the complete Open and then partially restrict some thermostatic valves on all Valves a very low opening position is reported to the central unit. This is an indication that the flow temperature was too high in this test. Now will first the flow temperature is lowered and the complete process sequence repeated. The opening position is now larger, so that this maximum Open position of the central device as the maximum position for the other Rule activity is entered.
