Refrigerant R410A: the leading HFC refrigerant for replacing R-22 used in residential and light commercial air-conditioning

R410A is the leading HFC refrigerant for replacing R-22 in positive displacement residential and light commercial air-conditioning and heat pump systems. It has higher cooling capacity and significantly higher pressure than R-22 and an intrinsically low toxicity. Because it behaves like an azeotrope, it is easy to service in the field. And R410A should be used only in systems specifically designed for R-410A.

Replaces

R-22

Applications

New residential and commercial air conditioning and heat pumps.

Positive displacement chillers.

Benefits

R410A has shown in tests to have 5-6% higher Energy Efficiency Rating(EER) than R22. R410A also has a higher capacity and pressure than R22, enabling the design of smaller, more compact air-conditioning equipment.
