Cooling CalculationsCooling Calculations
There is a direct relationship There is a direct relationship between energy consumption and between energy consumption and cooling requirements needed (3 BTU cooling requirements needed (3 BTU capacity needed for every 1 Watt capacity needed for every 1 Watt electrical load)electrical load)
