REFRIGERANTS

A DIFFERENT KIND OF COOL

DECARBONIZATION TECHNOLOGY

There’s no modern air-conditioning without refrigerants. These chemical compounds are responsible for transferring heat from one area to another, and are a foundational element of most HVAC units and heat pumps.

Refrigerants are essential and effective. And they are evolving. Driven by new regulations, manufacturers have switched to a different class of refrigerants, ones with a lower global warming potential (GWP) than their predecessors.

But not all low-GWP refrigerants are the same. The ideal option is one that’s tailored to the application. That can provide benefits beyond decreasing GWP — from higher-efficiency equipment to maximum lifecycle climate performance.

THE BENEFITS OF LOW-GWP

COMPLIANT: Meet new government regulations and building codes

ECOLOGICAL: Reduce the environmental impact of leaks and servicing

SUSTAINABLE: Align with green initiatives by reducing HVAC’s carbon footprint

Daikin is committed to R-32 as the best replacement for R-410A. This proven technology, found in over 280 million HVAC units across the globe, not only has two-thirds the GWP of R-410A, but can improve both part- and full-load efficiency by up to 12% compared to R-410A systems.

R-32 is a pure, single-component refrigerant. It doesn’t fractionate and, as a result, maintains performance efficiency over time.
R-454B, a proprietary blend, is comprised of R-32 (68.9%) and R-1234yf (31.1%).

R-32 IS WIDELY AVAILABLE

Unlike proprietary blends, R-32 is a commodity produced by many manufacturers around the world, making it widely available. As a high volume commodity, pound for pound R-32 has a lower price today than the proprietary blend R-454B. At a low price, with a low charge and high efficiency, there can be great savings when charging, servicing and operating R-32 systems.

R-32 HELPS CREATE SUSTAINABLE BUILDINGS

With the majority of a unit’s lifetime emissions coming from electrical power generation, a more efficient R-32 system can cost less to operate and can provide lower total life cycle emissions than a comparable R-410A system. Low charge and low electricity work together to limit emissions that contribute to climate change.
