| HVAC |
|
| Services |
- Support design engineers in developing new
HVAC systems by providing better understanding of flow characteristics
- Provide consulting and software for all levels
of engineering:
- Simulate laboratory testing and performance results
- Determine design features with major impact on flow performance
- Match components to system requirements
- Predict system performance
- Evaluate design modifications
- Optimize product design parameters
|
| A Typical Project Example: |
- Analyze Current Design
- The existing product or process is analyzed.
Results are correlated with experimental measurements.
- Parametric Analysis (Analyze Design
Changes)
- The effects of design changes are determined.
A statistical approach may be used to understand the combined effects of design changes.
|
| Benefits |
- Reduce building and testing
- Improved understanding of performance issues
- Faster way to evaluate design alternatives
|
| System Flow Analysis |
| The
design of new HVAC units requires the design engineer to mix and match standard components
to fit ever-changing space constraints. System flow analysis offers the ability to quickly
determine the effect of component modifications on system performance. Flow analyses can be performed to describe:
|
- System pressure drop
- Match point of total system resistance and
blower performance curve
- Changes in component losses on system pressure
resistance
- Flow distribution from branched distribution
ducts
- Changes in flow distribution due to duct shape
changes
|
- Changes in current draw of the blower due to
duct changes
- Loss in airflow due to system leaks
- Parametric analyses can be performed to
understand the interaction of design changes and system pressure loss.
|
| Component Flow Analysis Sequence |

model)
- Identify problem areas of:
- High velocity and pressure gradients
- Recirculation zones
- Losses
|
- Modify geometry and reanalyze for flow
improvement
