The air-conditioning data in
Table 2-10
are derived using the following equations.
•
Watts x (0.860) = kcal/hour
•
Watts x (3.414) = Btu/hour
•
BTU/hour divided by 12,000 = tons of refrigeration required
NOTE:
When determining power requirements, you must consider any peripheral equipment
that will be installed during initial installation or as a later update. Refer to the applicable
documentation for such devices to determine the power and air-conditioning that is required to
support these devices.
