Microcomputer Controls
A microcomputer-based controller
controls the air-cooled Series R
™
70-125
ton chiller. The microcomputer controller
provides better control than past
controls as well as several new,
important benefits.
Adaptive Control
™
Microprocessor
The microcomputer-based controller
allows Trane to optimize controls around
the chiller application and the specific
components used in the air-cooled
Series R
™
chiller. For instance, the
compressor protection system is
specifically designed for the air-cooled
Series R
™
chiller. A new leaving chilled
water temperature control algorithm
maintains accurate temperature control,
minimizes the drift from setpoint and
provides better building comfort. This
control, combined with linear
compressor unloading, also allows the
chiller to be applied in wider array of
applications, including variable primary
flow. The microcomputer control
incorporates improved chiller start-up,
load limiting, lead/lag, and compressor
run time equalization functions into
standard chiller operation. Interface with
outside systems such as building
automation controls is flexible and easy.
