HVAC Session Agenda

  • Alternate Paths for HVAC Assessment Tool Development

  • Proposed Phasing of Development

  • Review of Proposed Inputs and Actions

  • Wrap-Up



Stand alone modules l.jpg
Stand-Alone Modules

  • Advantages

    • Incremental Development

    • Exposed Algorithms

    • Fast Development?

    • Fast Calculations?

  • Disadvantages

    • Cumulative Errors

    • Limited Interaction Between Measures

    • Limited Testing of “Engine”

    • Needs New Support System


Simulation approach l.jpg
Simulation Approach

  • Advantages

    • Accuracy of Models

    • Interaction of Measures

    • Engine Already Tested

    • Leverages ExistingResources

    • Supports a Wider Varietyof Systems

    • Built-in Support

  • Disadvantages

    • All Eggs in One Basket

    • Potential Licensing Issues

    • More Complex Engine


Unknowns l.jpg
Unknowns

  • Development Time

  • Development Cost

  • Other …


Sample screens from equest wizard l.jpg

The program supports libraries of utility rates

Sample Screens from eQuest Wizard


Sample screens from equest wizard8 l.jpg

Selection of a cooling source changes

subsequent screens

Sample Screens from eQuest Wizard


Sample screens from equest wizard9 l.jpg

All types of economizers are currently available

And integrated with the other system characteristics

Sample Screens from eQuest Wizard


Sample screens from equest wizard10 l.jpg

You can have different pumping systems

You can have different types of chillers in a single plant
