Scientists warned us: the climate crisis is here, and now we are seeing for ourselves by facing new and unpredictable challenges.
As HVAC/R experts, we must do whatever it takes to reduce the environmental impact of air conditioning and refrigeration systems, sharing our know-how, collaborating, and changing our mindset for the better. The transition to lower GWP refrigerants, such as R-744 (CO2), hydrocarbons (R-600 or R-290), HFOs and their blends, and R-717 (Ammonia), indeed, is one of the most widely adopted solutions to decrease the direct emissions of the systems.
Even though this represents a huge step forward, we should consider that those kinds of refrigerants can often cause problems in the syste ...
