Changing a R22 System

Environmental Section

This section is to help you understand a little more about the Current news in the air conditioning sector, and how it may affect you/your business. If you have any questions queries call Stephen direct on his mobile on 087-6327783 and he will be happy to assist you.

R22 Phase Out:

From 1st January 2010, The Production of the Refrigerant Gas R22 will be discontinued. By the year 2015 it will be totally illegal to work on a R22 system, thus meaning a replacement system. If your business currently uses a R22 system, we at Shiva can offer you an alternative solution before the 2015 deadline… Depending on the condition of your current system, we can give you the option of ‘Retro Fitting’.

This involves keeping the original pipe-work and cables from your current R22 system (which is often the most expensive part of new AC Installations because of labour costs) and simply replacing both the indoor and outdoor units with modern 410A Inverter units, after the pipes have been chemically flushed. Newer units are also up to 70% cheaper to run than R22 systems.

In a recent survey 65% of people who Retro-Fitted there company’s AC systems in 2007, covered the full cost of the Retro-Fit within 2 years because of the reduction of energy bills, then constantly saved more money thereafter with cheaper electricity bills compared to the old R22 system they were using.

We strongly recommend upgrading your R22 system as soon as possible instead of letting your old system run until a fatal failure occurs, and inevitably contaminating the pipe-work, rendering it useless, and unable to use it for a Retro Fitting purpose.

F-Gas Legislation:

What is the F-Gas Legislation?

Fluorinated greenhouse gases (F-Gases)
The European Regulation on certain fluorinated greenhouse gases (Regulation 842/2006) came into force for most provisions in July 2007. Its principle aim is to reduce greenhouse gas emissions through the containment and prevention of emissions; phase out of these gases is not generally a requirement of the Regulation except for some specified uses. In many cases, ozone depleting substances were replaced by fluorinated greenhouse gases in the refrigeration and air conditioning sector. One of the specific requirements of the Regulation is to carry out periodic leak checking of equipment containing F-Gases, the frequency depending on the quantity of gas contained, as follows:

  • 3kg F-Gas content – minimum annual leak check
  • 30kg F-Gas content – minimum once per 6 months leak check
  • 300kg F-Gas content – minimum once per 3 months leak check

Therefore, while it is clear that there is some overlap with the requirements under the ODS Regulation, the requirements are more onerous under the F-Gas Regulation.

“Leak Check” means that the system is examined for leaks using direct and indirect measuring methods (yet to be established) focusing on those parts of the system most likely to leak.

The legal requirements came into effect on January 1st 2007. Products with less than 3kg of R410a or R407C and all products using R22 are exempt from this regulation – the minimization of refrigerant leakage is however an ideal for all systems.

3 Owners / operators of systems shall maintain records (available for inspection) on:

  • Details of each system containing 3kg or more of R410a and the required charge
  • Quantities added and/or recovered during servicing, maintenance and final disposal.
  • The company/technican who performed the servicing or maintenance
  • The dates and results of leakage checks

Systems shall be leak tested within one month of repairs being carried out to ensure that the repair has been effective. Contact us today for a demonstration or viewing, of our new maintenance schedule ledgers, supplied to our maintenance contract holders.

Recovery of Rerigerants from systems:

  1. Owners/operators of these systems shall ensure the re-cycling, reclamation or destruction of R410a by verified/certified personnel
  2. When an R410a container reaches the end of its life, the person utilizing the container for transport or storage purposes shall be responsible for the proper recovery of any residue
  3. Recovery, for the purpose of re-cycling, reclamation or destruction of R410a, shall take place before the final disposal of that equipment and, when appropriate, during it’s service and maintenance.

Training and Certification of personnel

There are minimum requirements of training and certification for both companies and personnel involved in installation, maintenance or servicing of equipment.

The operator of the relevant application shall ensure that the personnel are certified

Companies involved in the installation, maintenance or servicing of equipment shall only take delivery of R410a where their relevant personnel are certified (by 4th July 2009)
