CLIMATE CHANGE VEHICLE AIR CONDITIONING
The European Union's F-gas Regulation No 842/2006 became law on 4 July 2006. This imposes obligations on "operators" of this equipment from 4 July 2007 that you should know about. F-gases include HFC`s, which are the commonest refrigerants in use today. The Regulation aims to minimise emissions of these gases, which affect global warming if they escape into the air.
"Operators" are defined as the people or organisations that have actual power over the technical functioning of the equipment. The legal responsibility for compliance with the Regulation lies with the operator. For further details of the definition of the operator see the F Gas Support website. Any equipment small enough to plug in rather than have to be permanently wired is likely to be excluded from the requirements, other than an overall requirement to prevent leakage and to repair any leaks as soon as possible.
For stationary refrigeration, air conditioning and heat pump units over 3 kg charge (6 kg if hermetic), operators must
· Prevent leakage, and repair any leaks as soon as possible
· Arrange proper refrigerant recovery by certified personnel during servicing and disposal
· Carry out leak checks to the schedule shown below
· Ensure that only certified competent personnel carry out leakage checks
· Maintain records of refrigerants and of servicing
For non-stationary equipment (e.g. mobile units on trucks) and any other products containing F-gases, operators must ensure that appropriately qualified personnel are used to recover gases, as long as this is feasible and not excessively expensive.
Leak checking schedule
The leak checks must be carried out according to the procedure laid down by the Commission in October 2007 (Industry guidance is available from the Institute of Refrigeration or you can download the full text of the leak check regulation ). The schedule for leak checks varies depending on the amount of refrigerant in the system, as follows:
· At least annually for applications with 3 kg or more of F-gases (unless the equipment is hermetically sealed and labelled as such, in which case the threshold is up to 6 kg).
· At least once every six months for applications with 30 kg or more of F-gases
· At least once every three months for applications with 300 kg or more of F-gases
· Leakage detection systems must be installed on applications with 300 kg or more of F-gases, and when these are in place, checking requirements are halved
· If a leak is detected and repaired, a further check must be carried out within one month to ensure that the repair has been effective
Maintenance and servicing records
Operators of all stationary systems containing 3 kg or more of F-gases must maintain records including
· Quantity and type of F-gases installed, added or recovered
· Identification of the company or technician carrying out servicing and details of the Operator
· Dates and results of leakage checks, specifically identifying separate pieces of equipment containing 30 kg or more of refrigerant
It is the operator's responsibility to ensure that the relevant servicing personnel have obtained the necessary certification, which shows that they understand the regulations and are competent.
