Recovery Is Part of the AHU
Modern air-handling units treat recovery as a built-in module, not a bolt-on. Selecting the right integrated recovery means matching the core or wheel to the unit's airflow, static budget, and control scheme.
Selection Inputs
- Design airflow - supply and exhaust, ideally balanced
- Static pressure budget - what the fans can deliver after the core
- Effectiveness target - set by the energy or code requirement
- Control integration - summer bypass, frost, modulation
Module Choices
| Module | Fit |
|---|---|
| Crossflow plate | Compact AHUs, simple duty |
| Counterflow plate | Tight effectiveness, low-temp heating |
| Rotary wheel | Large AHUs, humidity control |
| Heat pipe | Rugged, no moving parts |
Verify
Confirm the module rating at the unit's actual face velocity and that the combined unit meets the fan and frost-control requirements.
