Refrigerant Choice:
R134a: General-purpose (GWP = 1430)
R1234ze: Low-GWP alternative (GWP = 7)
Ammonia: Industrial use (GWP = 0; requires safety protocols)
Efficiency Optimization:
VFD compressors save 25-35% energy at partial loads.
Free cooling cuts energy use by 70% when ambient <10°C.
Maintenance:
Air-cooled: Clean coils quarterly in dusty environments.
Water-cooled: Annual condenser tube brushing + water treatment.
