Carnet Bleu 2018_EN_BD / Das blaue Heft

Blue Handbook- "Blaues Heft" - 2018 In dieser Übergangszeit werden neue Kältemittel entwickelt, um jene mit hohem GWP zu ersetzen. Darum wurde soeben das Blue Book, dieses für alle Kältemittelbenutzer unerlässliches Tool, neu herausgegeben.

R-134a was the fluid of choice of automotive and agricultural air-conditioning system manufacturers. New cars now use R-1234yf. This fluid could also replace R-12 in existing systems by following the correct conversion procedure. Commercial specifications Purity: ≥ 99.5 % weight. Water content: ≤ 10 ppm weight. Non-condensables (gas phase): ≤ 1.5 % volume. High boiling residue: ≤ 0.01 % volume. Acidity (HCl): ≤ 1 ppm weight. Chloride ion test: negative. Oils Use a polyol ester (POE) oil. For car air conditioning we recommend to take the advise of the constructor as PAG oils are normally used. Check with Climalife regarding the viscosity of the oil selected for your application, and the miscibility with the fluid under consideration. Regulation The use and implementation of R-134a are governed by EU Regulation n° 517/2014. The recovery of R-134a is mandatory under EU Regulation n° 517/2014.
