Abstract

A heat-quantity counter or meter (WMZ) is installed across two locations at the energy storage unit, where current flows into the unit and where heat flows to the after-heat unit. Values are combined in the read-out and are passed to the computer or to a remote read-out using a meter-bus.

Description

ProblematikProblem

Es ist schwer für den Betreiber von solarthermischen Anlagen zu kontrollieren, wieviel Energie seine Anlage eingebracht hat, welchen Wirkungsgrad sie hat und wieviel Energie zusätzlich aufgewendet wurde. Ebenso schwierig ist es für den Installateur nachzuweisen, dass die Anlage gut funktioniert bzw. wenn Probleme auftauchen, wo der Fehler liegt. Mittlerweile wird für viele Anlagen ein "Garantiertes Resultat einer Solaranlage" GRS gefordert. Um dies nachweisen zu können, muss eine Solaranlage hinreichend genau vermessen werden. Die erforderliche Messtechnik ist teuer und unspezifisch.It is difficult for the operator of solar thermal systems to control how much Energy has brought in his plant, what efficiency it has and how much energy was also spent. It is just as difficult for the installer to prove that the system works well or if problems arise where the fault is. In the meantime, a "Guaranteed result of a solar system" is becoming GRS for many systems required. To be able to prove this, a solar system must be sufficiently precise be measured. The measurement technology required is expensive and unspecific.

Stand der TechnikState of the art

Momentan wird die Leistungsfähigkeit von solarthermischen Anlagen entweder durch aufwendige und teuere Messapparaturen erfasst, oder von eingebauten Wärmemengenzählern "manuell" abgelesen und berechnet, oder mit Hilfe von Zusatzgeräten in den Reglern erfasst. Dieses Verfahren ist mit einer grossen Unsicherheit behaftet, da der Regler im allgemeinen nicht kalibriert ist.At the moment, the performance of solar thermal systems is either through complex and expensive measuring equipment, or from built-in Read and calculate heat meters "manually", or with the help of Additional devices recorded in the controllers. This procedure is very uncertain affected because the controller is generally not calibrated.

Käufliche Wärmemengenzähler sind geeicht und sind bereits weitgehend mit dem M-Bus ausgestattet. Dieser ist speziell für die Erfassung und Abrechnung verbrauchter Einheiten spezifiziert worden. Commercial heat meters are calibrated and are already largely with the M-Bus fitted. This is especially for the recording and billing of used units has been specified.  

Innovationinnovation

Einige Wärmemengenzähler besitzen einen M-Bus und einen Speicher in dem Zwischensummen abgelegt werden. Diese Werte können nun auf einmal und für mehrere Zähleinheiten über den M-Bus ausgelesen werden. Eine Vielzahl von Wärmemengenzählern erlaubt es, Momentanwerte auszulesen. Diese Werte sind von der Unsicherheit her in einem engen und genau spezifiziertem Toleranzbereich anzusiedeln, weil sie geeicht sind. Mit Hilfe dieser Momentanwerte lässt sich die Leistungsfähigkeit einer solarthermischen Anlage
Some heat meters have an M-Bus and a memory in which subtotals are stored. These values can now be read out at once and for several counting units via the M-Bus. A large number of heat meters make it possible to read out instantaneous values. Due to the uncertainty, these values are to be found in a narrow and precisely specified tolerance range because they are calibrated. With the help of these instantaneous values, the performance of a solar thermal system can be determined

  • 1. mit einer definierten Messunsicherheit1. with a defined measurement uncertainty
  • 2. über einen Zeitraum kontinuierlich2. continuously over a period of time

erfassen und bewerten. Durch die uneingeschränkte Erweiterbarkeit aufgrund der M-Bus Spezifikation lassen sich damit auch detaillierte Messungen durchführen. Zudem ist es möglich über eine Fernausleseeinheit die Funktionstüchtigkeit der solarthermischen Anlage zu kontrollieren.record and evaluate. Due to the unlimited expandability due to the M-Bus Specification can also be used to carry out detailed measurements. In addition, it is possible to use a remote reading unit to ensure that it functions properly control solar thermal system.
