Diversity of Refrigerant Choice
• There is no one-size-fits-all solution.
• All refrigerants are included on the table of refrigerant choice
• Choose whatever refrigerant is best suited for each application.
• Daikin is developing R32 split air –conditioners from residential to commercial range
because R32 is better suited to these applications
