Update
4.1.1
Trane, in offering the Trane Air Conditioning Economics
(TRACETM700) computer program, accepts no
responsibility or liability for the design of buildings or their support systems
or for the accuracy of the economic analysis and the building and system air
conditioning load data. The economic analysis and the building and system air
conditioning load data are based on conventional economic and engineering
principles, plus financial and engineering data supplied only by the program
user. This TRACE 700 program is intended to be used as a comparative study of
operating efficiencies and costs of alternative air conditioning systems. Trane
further accepts no responsibility or liability for the suitability of the
building air conditioning system in providing proper temperature control,
humidity control, infiltration, air distribution and quiet operation.

dampers, additional static, fan energy, etc...).
- Dual path airhandlers (Split Dehumidification Unit).

update contains the following items:
- Added ASHRAE Standard 62.1-2004 ventilation calculations.
- Added ability to model shutoff vav boxes to certain zones connected to a
fan powered system (for example, interior zones).
