Like the weather, many talk about the need to cut energy use, but can do little about it. The technique described in this article has been tested in the field and has decreased energy consumption substantially. Along with energy saving, the required refrigeration plant size can be lowered. The play back period is normally less than two years. Systems with air cooled condensers have a lower EER (Energy Efficiency Ratio - Btu/watt) than water cooled systems for the same ambient conditions. The difference gets worse in hot dry summer months when the cooling load is at its maximum.
