Overview of ..
This Section of the Energy Efficiency Manual is for everyone
involved in the operation, maintenance, and design of central air
conditioning systems, refrigeration plants, and industrial cooling
plants. These include chilled water systems and central direct-expansion
systems. You will become an expert in making your cooling plant
Cooling accounts for a large fraction of the energy cost of modern
buildings. In warm and humid climates, cooling and dehumidifying
may account for more than half of a facility’s energy cost.
Cooling is a major cost of many industrial processes.
There is a rich field of opportunity for improving the cooling
efficiency of existing buildings and industrial plants. Many improvements
in cooling technology have made it possible to build new facilities
with improved cooling efficiency. There are also many techniques
for improving the efficiency of existing cooling equipment. The
energy conservation measures in this Section range from simple adjustments
to major plant modifications.
