2. Kilowatt input and wire-to-water efficiency of a pumping system,
which demonstrate the use of energy in a pumping system.
3. Kilowatts per ton efficiency for an entire chilled-water plant,
which includes the energy consumption of the pumps and cooling
towers, not just the efficiency of the chillers themselves.
4. Boiler efficiency as a percentage as related to entering water tem-
perature.

These efficiencies are possible now that digital computers are avail-
able to make the calculations rapidly and accurately. The equations
for HVAC systems and equipment included herein enable the HVAC
operator to observe these water systems and ensure that they are
functioning at optimal efficiency.

2.10 Additional Reading
It is important that the HVAC designer be well versed in the basic flu-
ids and services available at the point of installation of each project.
Local codes and services must be checked for compatibility with the
final design. The manuals of the technical societies are excellent sources
for additional reading, particularly those of the American Society of
Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and
the Institute of Electrical and Electronics Engineers (IEEE).
