The first is to know "220V Cooling Fan" total cooling demand, to understand the total cooling demand has the following three points:
1, "220V Cooling Fan" must be converted to heat (ie temperature difference DT);
2, offset wattage (W) conversion of heat;
3, "220V Cooling Fan" remove the heat required air volume (CFM). The total cooling demand is important for the effective operation of the system. Efficient operation of the system must provide the ideal conditions to make all components within the system can maximize the functionality and longest life.
