High-GWP Refrigerants: Stealth Climate Destroyers

The current state of refrigerant management is troubling. High-GWP refrigerants vaporize without a trace so enforcing proper disposal is difficult. They leak into the environment when first added to HVAC equipment, and again when that equipment is repaired, and when it is disposed of. Refrigerant will leak from a poorly installed connection. Unscrupulous workers sometimes vent refrigerant (rather than capturing and recycling it) when fixing pumps and other components…and then sell you more of the same refrigerant to recharge the system. Slow leaks in long refrigerant lines, such as those used in VRF systems, are often addressed by simply adding more and more refrigerant. And when equipment is decommissioned, scrap metal dealers don’t necessarily want to capture and store refrigerants, so there are “accidental” refrigerant leaks during transport and storage. Stopping these ...
