Control Trane’s Integrated
Comfort systems (ICS) concept incorporates the benefits of factory-mounted, wired,
and tested microprocessor controls on each piece of
Trane equipment described in this section. Trane Tracer building management
systems link the HVAC equipment into truly integrated comfort systems that address
the critical issues facing building owners, engineers,
and contractors.
Chillers
Trane chillers are available with a compressor type, refrigerant type, and capacity to meet nearly any need. These
chillers are designed to provide a reliable source of
chilled water and are equally suited for comfort, industrial, or process
applications.
Unit controllers factory-mounted on Trane chillers provide access to information
and functions within each chiller. This access allows
the building management products described in this catalog to optimize
the operation of each chiller individually and to
optimize their performance within a chiller plant.
You can link any of the chillers listed below to a Trane ICS to provide
system-level monitoring, diagnostics, and control
capabilities, including sequencing chillers as well as controlling pumps and
cooling towers:
- CenTraVac Centrifugal Chillers
- Series R CenTraVac Helical Rotary Chillers
- Air-cooled and water-cooled Helical Rotary Chillers
- Air-cooled and water-cooled Scroll Chillers
- Two-stage and Single-stage Indirect-fired Absorption Chillers
- Horizon Two-stage Direct-fired and Indirect-fired Absorption Chillers Refrigerant management monitoring
and reporting is also available for applicable
chillers.
VariTrane VAV Terminal
Units
VariTrane terminal units are available with either pneumatic, electronic,
or microprocessor controls (DDC/VAV).
Factory-installed DDC/VAV controls are available with all shutoff
terminal units, including parallel fan-powered and
series fan-powered units. Dual duct units are equipped with two Unit Control
Modules (UCMs)-one for the heat duct and one for the
cool duct.
The Variable Air Volume (VAV) UCM is a microprocessor-based, direct digital
controller (DDC) for the VAV terminal unit. It contains
the control logic to modulate the flow of supply air through the VAV terminal in
response to the load requirements within the VAV zone.
The VAV UCM can communicate with
the Tracer 100 series building controllers and the
Tracer Summit BCUs.
Commercial Self Contained Units
Trane Commercial Self Contained air conditioners efficiently bridge the gap
between unitary and central systems by
factory-packaging rugged commercial components in a floor-by-floor decentralized
system. Multiple, independent refrigerant circuits-using the 3-D scroll compressor—provide
high performance redundancy. For application flexibility, units are factory-equipped for either water-cooled or
remote air-cooled condensing. |
