XXX New Energy Vehicle (Shanghai) Co., Ltd. Workshop AHU EC Fan Energy-Saving Retrofit Case
New Energy项目
Home Cases New Energy
项目背景

AHU air‑handling units in lithium‑ion manufacturing plants run non‑stop year‑round, with strict requirements for airflow, static pressure, cleanliness and operational continuity. The on‑site original air handling units adopted the traditional configuration of AC induction motor plus belt‑driven centrifugal fans.

Conventional belt‑driven fan systems suffer multiple pain points. Mechanical losses arise from long‑term belt wear, leading to gradual system efficiency decay. Motor efficiency drops sharply under partial‑load conditions, resulting in high annual power costs. Frequent inspection and replacement of belts and bearings bring heavy maintenance workload. There is no operational redundancy for single fans; fan failure will directly disrupt clean‑shop production.

To meet the factory’s energy‑saving and carbon‑reduction goals, the customer launched an in‑depth energy‑saving technical retrofit for AHUs, without degrading air‑supply quality or interrupting continuous production. EBLUE delivered one‑stop EC fan‑wall retrofit services including site survey, fan‑wall solution design, product supply, installation and commissioning. All energy‑saving calculations of this project are based on the fair comparison benchmark of identical airflow and total static pressure, to ensure verifiable and auditable retrofit results.

羿清方案
设计工艺
High‑efficiency EC Direct‑Drive · In‑depth Energy‑Saving Technology for AHU Fans
With site investigation and self‑developed fan selection system, EBLUE replaces belt‑driven fans with EC direct‑drive fan walls plus intelligent group control. Following Site Survey – Solution Delivery – Implementation – Commissioning & Handover, it delivers verified ~25% measured energy saving without compromising clean air‑supply standards.
方案介绍
1. High‑efficiency IE5‑grade EC motors:
Lower power input and superior partial‑load efficiency versus conventional IE1‑IE3 AC motors.
2. Belt‑free direct‑drive for less maintenance:
Remove belt‑related losses; reduce vibration, noise and overhaul frequency.
3. Closed‑loop group control:
Adapts to filter / coil resistance changes; compatible with BA/BMS systems.
4. Parallel redundant fan wall:
Compensating output upon single‑fan failure to prevent production shutdown.
5. Modular & cost‑effective upgrade:
Minimizes downtime; static payback period around 1.5 years.
