1. Refrigerant replacement
With a view to the future eradication of certain refrigerants under the Kyoto Protocol, the use of R 22 (HCFC) has been reduced since 2001 and is due to be banned in 2015, both as a virgin product and for maintenance and servicing purposes. Production will cease definitively in 2026.
In view of the 14,000 t of R 22 contained in refrigeration systems of all kinds operating in 2008, the Steering Committee of the French Refrigeration Association (AFF) and UNICLIMA, together with specialists and major users, have looked into this serious problem to propose solutions to worried users.
It turned out that there are only three strategies:
retain R 22, a solution that can only be envisaged for end-of-life plants, provided that strict attention is paid to their containment, since from 2010 the supply...

Air conditioning – Refrigeration
In 2007, UNICLIMA companies saw their business grow by +5.7% compared to 2006. Business is therefore growing strongly on both the domestic and export markets.
As a result, and in contrast to previous years, the industry's growth rate is very close to the average for the mechanical...

Regulations
Pressure equipment regulations
In the past, it was defined by a decree of 1943, subsequently revised in 1960. As part of the harmonization of technical regulations, the European Union has issued a Pressure Equipment Directive (PED) (no. 97/23), which becomes the only rule in force in each member state; for France, the transcription is the subject of a decree and order no. 99-1046 of 13/12/1999.
