Heat exchangers - Method of measurement and evaluation of thermal performances of wet cooling towers
This European Standard specifies requirements, test methods and acceptance tests for thermal performances
pumping head verification of wet cooling towers and plume abatement for wet/dry cooling towers.
This European Standard is applicable to natural draught wet cooling towers (see in 3.1.2.2) fan assisted
natural draught cooling tower (see 3.1.2.3), wet/dry cooling towers (see 3.1.2.4) and "Mechanical draught
cooling towers", except series ones.
It specifies the test methods, the apparatus required, the limitation of errors and the method for results
examination.
The acceptance testing covers the verification of the thermal performance data and pumping head of the
cooling tower as specified in the contract between the supplier and the purchaser. If these tests are required
then this should be recognized at the time of the contract, as additional fittings, and preparations for the test
may be required.
Deviations from the rules laid down below as well as additions need special agreement between purchaser
and supplier and should be documented.
This standard does not apply to mechanical draught series wet cooling towers which are dealt with in
EN 13741.
NOTE Terms like "design", "values", "guarantee" and "acceptance" used in this standard should be understood in a
technical but not in a legal or commercial sense.
Festgelegt sind die Anforderungen, die Prüfverfahren und Abnahmeprüfungen zum Nachweis wärme-technischer Leistungskenndaten, der Pumpförderhöhe für Nasskühltürme sowie zur Verminderung von sichtbaren Schwaden für Nass-/Trockenkühltürme. Die Festlegungen gelten für Naturzug-Nasskühltürme, für Naturzugkühltürme mit Ventilatorunterstützung, für Nass-/Trockenkühltürme und - mit Ausnahme von Serienkühltürmen - auch für zwangsbelüftete Kühltürme. Es werden Prüfverfahren, die erforderlichen Prüfgeräte, Fehlergrenzen und das Verfahren zur Auswertung der Ergebnisse festgelegt.
