Transcript Why did We Develop this Tool?

ClimateMaster eQUEST (3.56)
An All-in-one Tool for Water Loop and
Ground Loop Heat Pump Systems
Design and Energy Analysis
Xiaobing Liu, Ph. D.
Why did We Develop this Tool?
•
•
•
•
Compare operating cost of WL/GL HP
system with other HVAC Systems
Size ground heat exchangers
Compute energy savings to get tax
credits and deductions
Make life easier

eQUEST 3.55 was approved by the California Energy
Commission as a 2001 Title 24 non-Residential ACM on
4/27/2005 (an eQUEST 2005 Title 24 non-Residential
ACM is being prepared but is not yet available.)
Advanced GLHE Model
•
•
•
•
•
G-function based algorithm
Account for various geometries of
borehole field
Account for grouting effect
Informative input guidance
Vertical ground loops only for now

•
Calculate hourly building loads
Simulate almost ALL HVAC systems
including WL/GL HP
Graphical reports
State-of-the-art tool
– First (only) to integrate the advanced GLHE
model with hourly building simulation
