Maintenance rhythm

A semi-annual inspection – rotation check, seal inspection, and a clean if pressure drop has risen >15% – prevents most failures. Track 효율과 압력 손실 조기 편차를 잡기 위해 각 서비스 시.

Commissioning and baseline checks

Most wheel faults surface only after a baseline is established. During commissioning, record the supply and exhaust temperatures, the wheel speed, and the pressure drop across both sides at design airflow. These figures become the reference against which later drift is judged. A wheel that tests well on day one but loses several percentage points of effectiveness within a season usually signals fouling or seal wear rather than a design error.

Building management system alarms

Where the wheel is controlled by a building management system, set alarms on the metrics that fail first: a rising pressure drop points to fouling, a falling exhaust temperature points to reduced rotation or matrix blockage, and erratic current draw on the drive motor points to belt or bearing issues. Trending these values weekly catches problems weeks before occupant comfort is affected.

Seasonal operation notes

In shoulder seasons the enthalpy difference between streams is small, so faults are easy to miss. Use the high-load heating and cooling months as your verification window. Also confirm that any summer bypass damper seats fully, since a leaking bypass short-circuits recovery and mimics a failed wheel.

자주 묻는 질문

How often should an energy recovery wheel be inspected?
A semi-annual inspection is recommended, with rotation and seal checks and a clean when pressure drop rises above about 15 percent. In dirty or humid environments inspect more often.

Can a fouled wheel be cleaned in place?
Yes. Wash the matrix with low-pressure water and a mild detergent, and let it dry fully before restart. Avoid high pressure that could deform the matrix.

Why does my wheel frost up in winter?
The exhaust-side temperature can fall below freezing. Enable the purge sector, reduce wheel speed, or add preheat, and confirm a proper defrost cycle is configured.

How can I tell if leakage is wasting energy?
Check the supply and exhaust pressure balance and the seal strips. Worn seals raise carryover; verify with a pressure differential test and, where needed, a tracer check.
