External Flow & Bypass
Hidden Cost Analysis

The recirculation of exhaust air or generator gases by your external units (IEC, Chiller, etc.) not only wastes energy but also causes capacity derating and PUE degradation.

Derating Effect
Recirculation of hot air lowers thermodynamic capacity. Equipment is forced to work harder.

ASHRAE TC 9.9 & Alkazar Case Study

Real Field Finding: In a real scenario study where rooftop generators are active, wind effect directed 400°C exhaust gas to the cooling units, increasing the intake temperatures up to 49.4°C and the bypass ratio to 57%. This leads to capacity failure and hardware malfunction.
