Climalife - helping you move to lower GWP refrigerantsClimalife UK
The graph showing the phase down of HFCs as required by F-Gas Legislation has been well used to demonstrate the reductions that will be required. Using the graph will help you to understand the need to move away from the higher GWP refrigerants at the earliest opportunity.
The first reduction step occurs in a couple of months time when there is a 7% reduction in the amount of HFCs that are allowed to be placed on the market in 2016.
The effect of the phase down can be mitigated in a number of ways, firstly by reducing leakage from existing systems, secondly by converting those with high GWP refrigerants to lower GWP alternatives and thirdly by using lower GWP refrigerants in new equipment. With a GWP of 3922, R404A is one of the more obvious products which need to be replaced and a number of lower GWP alternatives are already available and in stock.
Read the Climalife article What can we use to replace R-404A?
So far the shift has been fairly gradual but the 2018 step reduction of 37% is going to be a dramatic one which will affect price and availability particularly of the high GWP refrigerants. It is therefore a very good idea to start reducing your dependency on refrigerants such as R404A and R507.
In 4 years, any refrigerant with a GWP of 2500 or more will be banned in new equipment and virgin product won’t be allowed for servicing systems with a charge over 40 CO2 eqT (10.4kg R404A). It therefore makes sense not to use such refrigerants in new equipment or to convert other systems to such refrigerant now.
The problem is already highlighted in this: ACRIB document and BRA document.
Climalife UK already stock and supply a number of lower GWP alternatives and is giving good advice to its customers on the suitability of the products available for their systems.
