Abstract
This paper discusses the performance of an off peak ice
storage air conditioning system
installed on an office warehouse
building in Dallas, Texas. The
system also incorporates a low
temperature (45 degree) air
distribution system utilized with
parallel fan-powered VAV boxes.
The entire system is controlled by
a microprocessor based Building
Automation System (BAS)
incorporating state-of-the-art
direct digital controls (DDC). The
economic performance of the system
will be discussed by comparing
utility bills, and the system
performance will be observed
through the use of actual trend
logs taken from the BAS on a
typical summer day. The reduced
space relative humidity levels,
resulting from the low temperature
distribution system, will be ahown
in actual trend logs also. The
method of distributing low temp air
without causing occupant discomfort
(cold air dumping) will also be
discussed.
