R22 Air conditioning – Regulation Changes for Commercial Air Conditioning Units

Replacing the R22 Gas in Air Conditioning Units


In recent years, owners of air conditioning units may have become aware of 2000 EU legislation regarding the traditional R22 gas no longer being used and completely banned as of 2015. As the R22 phase-out reaches its end in the next few years, alternatives such as the R410a are being introduced. This is a blend of HFCs which are not considered to contribute to the depletion of ozone.

R22 Air conditioning gas – your options

Anyone who has bought an air conditioning unit in the last 5 years will already know that new machines have been banned from using R22 as the gas ‘top up’ since 2010, and now a final ban will ensure that even recycled fluid is no longer allowed. This is of particular importance for businesses and commercial companies who will be expected to comply with this legislation. There are several options available to companies: modification of existing machines in order to accommodate a new refrigerant such as the R410a; plant replacement for unreliable or malfunctioning machines, and designer replacements for refrigerant parts.

How does R410a gas compare?

Customers who are concerned about the introduction of R410a to their air conditioning units might want to know how it compares in performance with the R22. Firstly, most of the newer models built since 2000 are able to run using R410a – so there should be no problem. Those built after 2010 when R22 phase out began were designed to the preferred gas’s specifications. Users will notice that their machines work better as the R410a can actually absorb more heat than the R22 meaning the AC unit is cooler. The new gas is also able to function at higher pressures than the R22 and there is less chance of the unit cracking.

R22 phase out = more efficient air conditioning

It is however important not to use R410a gas in A/C units which were built before the R22 phase out, as this could cause the compressor to fail and the unit will almost certainly break down. For most users of air conditioning units however, the R22 phase out could result in them experiencing more efficiency and better performance than previously.
