REFRIGERANTS


greater. Reducing leaks not only saves money on refrigerant but also reduces demand on quota. Recovering and reclaiming for reuse is also very beneficial to quota as these products are quota free. Many leaks, if found early, can significantly reduce the amount of refrigerant lost. With quota likely to be tight again the emphasis of all contractors should be to upsell their services for better leak management and prevention.


With lower GWP choices needing to be made for new equipment, the low GWP A2L refrigerants, along with ammonia, carbon dioxide and hydrocarbons, will provide the way forward as the market learns to use these products in increasing quantities in equipment designed for them.


The best way to keep the lid on refrigerant prices is to reduce demand for higher GWP refrigerants and stay below the quota cap. R454A, R454C and R455A are competing to be used in refrigeration applications where R404A was used in the past, whilst R1234yf, R1234ze, R513A and R450A are R134a alternatives. Meanwhile R32, R452B and R454B are similar to R410A. All the above have a GWP below 750.


Use of low GWP mildly flammable A2L refrigerants needs to follow EN378 charge criteria for different location and access categories. With additional measures such as ventilation, leak detection and access restrictions, the charge size can be increased but needs to be coupled with a risk assessment.


Those sectors that can use CO2 and ammonia in new equipment can also help reduce the


pressure on quota.


At the end of this year, refrigerants with a GWP > 2500 will be banned from new stationary equipment, but this should not present a problem as lower GWP solutions are available. The servicing of such equipment with refrigerant with a GWP over 2500 from the end of this will also be restricted to using reclaimed or recycled product where the charge is over 40 tonnes CO2 equivalent.


Do not wait for 2021 to start moving to lower GW P refrigerants just because the pressure may feel as if it off; start the move today by talking to your equipment and compressor manufacturers to ensure they quickly bring to market equipment to support the very low GWP A2L refrigerants.
