Overview of ..
This part of the Energy Efficiency Manual presents energy
conservation measures limit the operation of equipment to the times
when it is actually needed. Turning off equipment when it is not
needed is the most powerful principle of energy conservation. The
methods presented here minimize the operation of the big cooling
machines in central cooling and refrigeration plants, along with
their auxiliary equipment.
Another important principle is to select the most efficient combination
of equipment for each set of conditions. For example, as each chiller
starts or stops, the appropriate pumps in the chilled water and
cooling tower systems should start or stop. You will learn how to
accomplish this, including the use of inexpensive sequencing controls.
All these activities involve control. They may provide large savings
at modest cost. Most of them are easy to accomplish.
