It's about
efficiency.
Climate change is forcing all industries to look for more efficient and sustainable solutions. The HVAC
industry is no different. Proposed regulations aim to limit or reduce the use of R-410A due to its high
global warming potential (GWP). As a result, HVAC leaders are innovating, with higher efficiency
improvements geared towards both refrigerants and equipment.
The case for R-32.
R-32 is not new to the market. In fact, it's been a primary component of refrigerant blends for years.
But it's time to look beyond the table stakes of low GWP to the merits of overall efficiency.
Since the advent of R-410A, efficiency improvements in a vapor compression system have been
traditionally achieved mainly through the design of the unit's compressor, condenser and evaporator coils,
and system controls. However, these design improvements are limited by the refrigerant's thermodynamic
properties. Replacing R-410A with a refrigerant such as R-32 can take HVAC component design and
system efficiency to the next level.
HVAC systems optimized to use R-32 perform with up to 12% higher efficiency
than similar R-410A equipment.
R-32's excellent thermodynamic characteristics
make it the easy choice for the next generation,
low GWP alternative to R-410A. HVAC systems
optimized to use R-32 perform with up to
12% higher efficiency than similar R-410A
equipment. This is mainly possible because of
the thermodynamic properties of R-32. R-32 can
provide a larger capacity per pound (or kg) of
refrigerant than R-410A. Since a smaller refrigerant
volume is required to transfer the same amount of
heat energy, less refrigerant needs to pass through
the compressor, reducing the amount of work and
energy consumed.
