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.
