From 31 December 2009 no more virgin R22 refrigerant can be sold in the UK, in fact it will be against the law to even use virgin R22. Any virgin R22 still in the UK after that date must be sent for destruction, leaving only reclaimed R22 available to maintain existing systems. From1st January 2015 even reclaimed R22 will not be allowed to be used.
There are drop in replacement refrigerants but may necessitate the changing of some components of the refrigeration system for example driers, expansion valves, oil. We would be pleased to advise you on this possibility.
Many systems will need to be renewed completely as some are very old systems now and may be uneconomical to maintain in use.
The end of R22 availability represents an opportunity for old , inefficient systems to be renewed. New R22 equipment was phased out in 2003 and so remaining equipment will be at the end of its life shortly. There are energy consumption savings to be made on the new generation of equipment available now and even some ECA tax allowances. Please feel free to ask for details.
Doing nothing is not an option, so make sure your business has a phase-out plan in place.
Remember should you need to replace your current system , we will be happy to quote you for a new efficient system complete with installation by REFCOM registered engineers.
COUNTDOWN TO COMPLIANCE
01 Jan 2004 Ban on the introduction and supply of new air conditioning systems operating on R22
31 Dec 2009 Supply of new R22 refrigerant used to service RAC equipment is banned
01 Jan 2010 Only reclaimed or recycled R22 refrigerant may be used from January 2010 until 31 Dec 2014
01 Jan 2013 Following the phase-out, the cost of R22 refrigerant could quadruple in price year on year, and supplies of recycled R22 could run out by 2013
01 Dec 2014 Systems operating on R22 refrigerant will be classed as 'not serviceable.'
31 Dec 2014 A complete ban on R22 refrigerant, including reclaimed or recycled, comes into force
THEORY OF OZONE DEPLETION
Ozone is a type of molecule that is made from three connected oxygen atoms, which is written in scientific terms as O3. It is mostly found in the stratosphere, and absorbs harmful ultraviolet radiation tyhat would otherwise find its way down to us and cause a variety of hazards for humans, animals and plants.Stratospheric ozone is different from ground level ozone which contributes to smog in cities.
Ozone is constantly being made in our atmosphere, mostly by collissions of oxygen molecules (O2) and (O). It is also continually being destroyed by similar collissions between O3 molecules and O atoms, resulting in pairs of O2 molecules. In theory then there should be a balance between ozone creation and destruction, resulting in a constant layer of ozone.
HOW CAN CFCS AND HCFCS AFFECT THE OZONE LAYER?
CFC molecules are made of chlorine, fluorine and carbon, and HCFC molecules also have hydrogen atoms attached. When these molecules are emitted to the atmosphere they are eventually broken down into their individual atoms. The chlorine atoms then react with the ozone and cause ozone destruction to happen faster than ozone creation.
WHY DO WE NEED TO STOP OZONE DEPLETION?
Because stratospheric ozone protects us from harmful UV rays, ozone depletion is a major concern for life on earth. The damaging effects of depletion include an increase in skin cancers and cataracts, and even a reduction in food crop yields.
HOW CAN USING A NEWER REFRIGERANT HELP?
Using a newer non depleting refrigerant such as R410A in air conditioning applications which is not a CFC or HCFC means that it emits no chlorine to the atmosphere and thus does not interact with the ozone layer as it breaks down.
