The clock is ticking for R22 Refrigerant Gas, due to be Phased Out by 2015
Operators of air conditioning systems, currently running on R22 need to start planning ahead, the use of virgin HCFC R22 gas was banded from 31/12/2009.
The manufacturer of R22 HCFC gas stopped from December 2009.
Currently only existing stocks of R22 refrigerant gas and recycled R22 gas is being allowed to be used until 2015, after this date the use of any recycled R22 gas will also be completely banned. Any system running on R22 gas after January 2015 that develops a leak will have to be converted to run on an alternative approved refrigerant gas, such as R417a.
R22 is already becoming rare and difficult to obtain, even from well known and established suppliers. Prices have started to increase and we are receiving frequent price increase flyers from our suppliers.
Chillaire have been sending out regular notices to their customers, who currently have R22 systems on their premises, advising them of the current situation and putting forward options to them,
There are two real options available to the customer
Have the HCFC R22 gas charge removed from each of their air conditioning systems, and replace it with R417a drop in gas or an alternative equivalent. This would mean having to reclaim all of the R22 gas, carry out a nitrogen purge and then charge up with the new R417a (or equivalent approved) refrigerant gas.
Replace the existing HCFC R22 system with the a newer R410a system
However things customers need to consider before making their decision,
1/ Age of the existing equipment and condition
2/ Life expectancy of the existing system
3/ New 3 to 5 Year warranties available on any new system installed
4/ Running costs of the old systems compared to a new system, new systems are high energy efficient inverter systems.
5/ Heat pump heat ration has increased from 4:1 to 6:1 with the new systems.
6/ New technology, the latest technology may be of benefit.
New Refrigerants for the Future
Leading innovations in refrigerants
In response to the ban on CFC and HCFC-based refrigerants (F-gas regulation), the industry is undertaking extensive research to introduce more environmentally acceptable alternatives to refrigerants used in the past. Daikin is at the forefront of the drive to find low Global Warming Potential (GWP) and/or natural refrigerants.
Daikin is already investigating refrigerants such as R32 and CO2, but also advises that decision makers should take into account the indirect CO2 emissions generated during the total lifecycle of a product and not only look at the GWP of the refrigerant. Depending on the application, the most efficient refrigerant option should be chosen.
For example, Daikin has developed a highly innovative VRV CO2, as an alternative to today’s refrigerant based systems, thus harnessing the environmental advantages of CO2, which has with the lowest possible Global Warming Potential, to create a safe and viable refrigerant.
