Assuming a computer room is configured in such a way that either is an option, hot aisle containment may be seen as the better option because it has some thermal efficiency and ride-through advantages. Hot air is concentrated in this aisle and directed back toward the cooling system. However, because every computer room is unique, there is no one definitive solution. Cold supply air is then. Aisle containment strategies, specifically Hot Aisle Containment (HAC) and Cold Aisle Containment (CAC), are critical for separating hot and cold airflows, preventing mixing, and optimizing airflow management. Preventing the bypass of cold air and the recirculation of hot air. Both containment methods can be equally effective, but there are advantages and. This guide compares hot aisle containment and cold aisle containment head to head, walks through the capex and opex math, and covers the standards (ASHRAE TC 9. 9, NFPA 75, ASTM E-84) that govern what you can actually install.
