HVAC Products Update

Why update? 

• Environmental Issue 

– ODP & GWP 

– Phased out R22 

– Use of environmental friendly refrigerant 

R407C, R410A, R134a, R123 

• Energy Issue 

– Building Energy Code – Chiller COP 

– Air-Cooled to Water-Cooled plant conversion 

– Airside Energy Recovery 

• IEQ Issue 

– Air quality, 

– Humidity control, 

– Acoustic, 

– Thermal Comfort
