Selection Considerations: Heat Rejection Method

For medium-to-large installations above 200 kW cooling capacity, the choice between air-cooled and water-cooled heat rejection impacts total cost of ownership over the 15-20 year equipment lifecycle.

Air-Cooled Systems

  • Lower installation cost (no cooling tower, water treatment, or basin)
  • Zero water consumption — preferred in water-scarce regions
  • Simpler permitting and reduced maintenance (no Legionella monitoring)
  • COP typically 2.8-3.5 — adequate for facilities under 500 TR
  • Higher noise levels and larger rooftop footprint at scale

Water-Cooled Systems

  • Higher COP (5.0-6.0) — 30-50% lower energy cost at equivalent capacity
  • Superior part-load efficiency (IPLV 0.40-0.55 kW/TR with VFD)
  • Longer equipment life (25-30 years vs. 15-20 for air-cooled)
  • Preferred for data centers and process cooling above 500 TR
  • Requires cooling tower maintenance, water treatment, and 3-5 L/kWh water consumption
