Development of Diagnostic Rules for a Dry Bulb Economizer Mixed Air Loop
Abstract
Diagnostics of heating, ventilating, and air-conditioning
(HVAC) systems is becoming increasingly important because
of the rising cost of operation and maintenance of HVAC
systems. At the same time, computer costs are tumbling
allowing their use in new situations such as HVAC diagnostics.
The Army has developed standard HVAC system
configurations, thus facilitating development of knowledge
bases for those systems. This paper describes the development
of if-then-else rules which make up part of a knowledge base
for a two fan variable air volume (VAV) air handling unit.
Rules for the mixed air loop with a dry bulb economizer are
presented.
