Heat Dissipation Lab
THERMAL LOAD ANALYSIS (BTU/HR)Based on ASHRAE TC9.9 Recommended Envelope. Calculation includes equipment dissipation and latent heat from occupancy.
Physics & Methodology
Heat dissipation in network environments is calculated as the sum of Sensible Heat (Equipment) and Latent Heat (Occupancy/Environment). The primary unit of measurement for cooling requirement is the **BTU (British Thermal Unit)** per hour.
Where $P$ is total power in Watts, $3.412$ is the constant for Sensible Heat Conversion, $N$ is occupancy, and $A$ is surface area.

Data Center Cooling Analysis
ASHRAE Guidelines: Data centers should maintain inlet temperatures between 18-27°C (64-80°F). Every 1kW of IT load generates 3,412 BTU/hr of heat. CRAC/CRAH units must provide sufficient airflow (CFM) to maintain the temperature delta between cold and hot aisles. Always size cooling systems with 20-30% overhead for redundancy and future growth.
