About this file
This document is a Heat Load Calculator worksheet used to determine cooling capacity requirements for IT equipment in a facility. The calculation is based on one IT equipment unit with a power supply wattage of 8,697 watts, which at 70% load generates 6,087.9 watts or 20,759.74 BTU/hour. The worksheet applies two additional buffers to the base equipment heat load: a 10% buffer for occupancy and lighting, and a 20% buffer for environmental radiating heat in the building and surge capacity. These buffers increase the total heat load from 20,759.74 BTU/hour to 26,987.66 BTU/hour.
The final calculation converts the total heat load to cooling capacity by dividing the total BTU/hour by 12,000 (the standard conversion factor), resulting in a requirement of 3 tons of cooling capacity necessary for the facility. This worksheet appears to be a technical planning tool for determining HVAC cooling system specifications rather than a formal contract solicitation document.
