Now is the time to replace R404A and R507


With refrigerant prices escalating at rates never seen before, the market is waking up to the reality of what the F-gas quota reductions mean. It remains to be seen if it has grasped the full extent of the fi rst very big reduction in quota coming in 2018, says Peter Dinnage, technical director at Climalife.


W


ith one major producer announcing they won’t be selling R404A and R507 next year and another doubling the price every couple of months, it’s clear that the time has come to stop using R404A and R507 and to switch to lower GWP alternatives.


No one predicted the scale and frequency of increases we have seen on HFCs this year and we still have fi ve months to go. With each price increase, demand has not decreased but instead increased.


This in turn has fuelled further increases in an attempt to dampen demand, but so far that has not happened. The question now is, do the producers still have enough quota left for supplies for the remainder of the year? It is worth remembering they can sell a lot more of the lower GWP refrigerants than they can those with a higher GWP. With the price of R404A and R507 higher than the alternatives and likely to keep going up, a new driver exists to move to lower GWP refrigerants - that of price.


New equipment doesn’t need to use R404A There is no reason why new equipment should still be installed with R404A or R507. All the leading compressor manufacturers approve lower GWP alternatives, and if they don’t, use compressors from those that do. Those still using R404A and R507 in new equipment are using up quota that could otherwise be used for larger quantities of the lower GWP refrigerants. In the case of R-448A and R-449A, that’s nearly 3 times as much. In 2018, when the fi rst big step of the phase down applies, we will see a 32% reduction in CO2 equivalent tonnes available for the market compared to 2017. This is a 37% reduction from the 2015 baseline, but with the pre-charged equipment imports part of the quota, it is closer to a 44% reduction from 2015.


Will you still be able to buy R-404A next year? Yes, but it may be very diffi cult to get hold of and the price
