Datacenter Power & Cooling Engineering Principles
Designing electrical feeds and HVAC cooling for high-density server racks requires balancing Apparent Power (kVA), Active Power (kW), Power Factor (PF), and the 80% continuous load safety rules mandated by National Electrical Code (NEC) Article 210.
Key Electrical Formulas
- Single-Phase Power:
P(kW) = V × I × PF / 1000 - Three-Phase Power:
P(kW) = √3 × V × I × PF / 1000 - Heat Dissipation:
BTU/hr = kW × 3412.14 - Cooling Tons:
1 Ton of Refrigeration = 12,000 BTU/hr
