TRACE 700 Chiller Plant Analyzer software saves time by allowing easy
plant configuration comparisons with a detailed wizard. The program
calculates the energy and economic effects of virtually any chiller
plant configuration using load profiles generated based on location
and pre-defined building types. The software uses the accuracy of the
TRACE 700 calculation engine with basic user-defined inputs for
cooling and heating peak loads, building type, and building location.
Select multiple chiller plant configurations—decoupled
chillers, parallel chillers, variable primary flow, thermal storage,
low-flow applications and many others—for analysis
Define
cooling towers, chilled water and condenser pumps, free cooling,
custom utility rates and others
Compare up to four
different chiller plant configurations, full load energy rates, or
any other parameter related to the plant
Familiar TRACE
reports display both energy usage and economic values including life
cycle costs and comparisons between multiple alternatives
TRACE Visualizer allows users to create custom graphs
To install and run the program you will need: a Pentium® 4 or higher
processor, Microsoft Windows® 7/8 operating system, at least 1
gigabyte (GB) of RAM, and 500 MB of free hard-disk space (750 if
Microsoft .NET Framework version 2.0 is not already installed).
[Version 6.2.9] 10/3/12 This update contains the following items:
Added kWh/Ton-hr metric to the economic summary report. This
measures the plant's overall energy efficiency.
Added
90.1-2010 library members (see 90.1-2010 install for further
updates. This can be accessed through tranecds.com)
Updated
both evaporative and dry fluid cooler calculations. The updates are
based on EnergyPlus algorithms.
Updated 90.1-2010 Heat Pump
library members to comply with IC 90.1-2007-09 of ANSI/ASHRAE/IESNA
(Operation between 40F-17F).
Updated the default cooling
tower throttling value. Changed from 5F to 0.5F.
Updated
the cooling equipment tab to allow a condenser water pump for each
chiller when a plant level cooling tower is applied.
Fixed
the chilled water pump(s) incorrectly staying off when the lead
chiller is scheduled off but the remaining chillers are scheduled
available during an hour when Thermal Storage has met the entire
cooling load.
Fixed a "divide by zero" error in
the visualizer that was causing the "Bldg Elec Monthly Energy
Costs by Equip" to go to infinity.
Fixed the
"plants" entered values report which was incorrectly
displaying pump power.
Fixed the plant chilled water pump
sizing to correctly use the chilled water evaporator leaving
temperature when W/gpm is selected.
[Version 6.2.8] 3/30/12 This update contains the following items:
Added five Mexican weather libraries with the origin filetype
appended to the name.
Added VAV IntelliPak and Voyager
rooftops in the cooling equipment library.
Added two new
air cooled chiller/ice storage templates for the Plant Wizard.
Changed conversion for ft. of water in Rate Structure
Library.
Changed the Utility Rates Library to allow six
significant digits after decimal.
Fixed an error that
reported excessive tower makeup water in the WSHP loop.
Fixed an error that prevented the cooling tower unloading curve
to unload correctly when using kW units.
Fixed an error
that incorrectly calculated the dry cooler energy consumption when
set as a heat rejection device.
Fixed an error for Mexican
weather files due to unit conversion error that presented very low
humidity ratio values.
Fixed an error that defaulted to the
library pump flow rate value when the hot water pump rate was
entered as zero. User must select “none” in the pump field.
Fixed an error in the Visualizer that did not reduce the
electric demand when lighting demand was unselected from the
graphs.
Fixed an error where units of Hp and kW/cfm were not
being converted correctly.
Fixed an error that did not use
the Vertical bore imported by the user.
Fixed an error that
incorrectly sized the chiller when only a base utility was assigned
to it.
Fixed an error that calculated incorrect energy
consumption when a dry cooler was selected as a heat rejection
device and a fluid cooler was selected as a free cooling
device.
Fixed an error that did not show the cooling tower
heat rejection in the geothermal summary report.
[Version 6.2.6] 9/1/10 This update contains the following items:
The Fuel Source and Reject Condenser Heat to Reference Type
fields have been updated to Heating Plant and Heat Rejection
Equipment, respectively for:
Air to Air Heat Pump
Air to Air HP w/ Demand Defrost
VRF Heat Pump
VRF Heat Pump (digital scroll)
VRF Heat Pump
(Variable Speed Compressor)
Default Water Source
HP
Ground Source HP – High Effic

Water Source HP – High Effic
Water Source HP – Reg Effic
Added
compressor energy breakout options for unitary equipment to allow
for packaged energy rates to be entered without manual
separation.
Added the ability to model heat recovery VRF
systems and two default VRF heat recovery plants.
Moved
Energy Source from the Controls section to the Cooling Equipment
screen.
Moved Reject Condenser Heat from the Controls section
to the Cooling Equipment screen.
Moved Reject Heat to Plant
from the Controls section to the Cooling Equipment screen.
Removed options to view archived or T600-named library
entries.
Increased the number of significant digits on the
Economic Parameters report.
Numerous updates for the
Bidirectional Cascade flow scheme when modeling a central geothermal
system.
Fixed an issue that prevented the GLHE temperature
from surpassing the design condenser entering or going below the
design minimum temperature.
Fixed an error that prevented
the Plants Entered Values reports from being displayed.
Fixed an error that prevented the design chilled water
temperature from being copied from the library to the Controls
screen.
Corrected an error that doubled the oversizing for
individual equipment on the Equipment Energy Consumption report when
Link Airside Coil Capacities was enabled.
Fixed an error
where Chiller Tower Optimization was not properly used with respect
to the chiller.
Fixed an error that incorrectly calculated
cooling tower make-up water when using gpm or lps.
Fixed an
error that increased the FL rate in heat recovery mode for a heat
pump by 12.
Fixed the DHW condenser heat recovery system
when using Reject Cond Heat = Domestic Hot Water.
