PUE检测---如何测量丏用数据中心的PUE
Chilled Water Source Energy (MWh) =
Source energy weighting factor
× Density of the fluid
× Specific heat of the fluid
× Time
× Flow rate (average flow rate during the period)
× Δ Temperature (Water supply vs. return)
× Unit conversion constant
Chilled Water Source Energy per year (MWh) =
Average flow rate (m³/s) × Δ Temperature (Kelvin) × 146,607.36 (MWh·s·K/m³)
Source energy weighting factor = 0.4
Density of water = 1000 kg/m³
Specific heat of water = 4184 J/kg·K
Time = 31,536,000 seconds/year
Unit conversion constant = 3,600,000,000 Joules/Megawatt·hour
