Development of HVAC System Performance Criteria Using Factorial Design and DOE-2 Simulation
Abstract
A new approach is described for the development
of Heating, Ventilating, and Air-conditioning
(HVAC) System Performance Criteria for the Texas
Building Energy Design Standard. This approach
integrates a design of experimental methodology and
DOE-2 simulation to identify the effects of control
parameters on HVAC system energy performance.
Three new criteria - transport, plant, and system
performance factors-are used as measures of system
performance. The procedure has been applied to the
development of criteria for a variable-air-volume
(VAV) and a constant-air-volume (CAV) system in
three Texas climates. The results show that the air
distribution system pressure loss, cooling coil exit
temperature set-pint, operation of an economizer,
and use of dead band controls have significant effects
on air transport energy use and total system
performance. The selection of control strategies and
set-points have a clear impact on energy use. There is
also a great energy-saving potential of converting
from a CAV to a VAV system.
