The HVAC system of metro stations operates continuously over long hours. Cooling towers and Air Handling Units (AHU) represent major energy‑consuming equipment in rail transit stations. Conventional fans suffer high power consumption and limited control strategies, leaving considerable potential for energy‑saving retrofits.
EBST carried out energy‑saving upgrade retrofits for cooling towers and AHUs at metro stations. By deploying high‑efficiency EC fans paired with touch‑screen intelligent control systems, remarkable power‑saving performance is achieved while ensuring operational conditions of equipment. It delivers a practical retrofit solution for carbon reduction of existing rail‑transit facilities.
1. Equipment Upgrade: Replace legacy conventional fans with high‑efficiency EC fans to eliminate belt‑drive transmission losses and boost motor operating efficiency.
2. Intelligent Control: A touch‑screen control system is equipped with multiple built‑in automatic control logics. It automatically switches operating modes for different seasons and time periods to dynamically adjust fan output power without on‑site manual intervention.
With the cooling tower outlet water temperature steadily maintained at 25 °C, actual operating power of fans drops substantially, delivering over 50 % comprehensive power-saving rate.
Metro systems feature long operating hours and high baseline energy consumption for ventilation and air‑conditioning. Leveraging automatic software control logics to match equipment operation modes for different scenarios, the retrofit yields substantial annual savings in overall operating costs.
EC direct‑drive fans remove belt‑drive assemblies, reducing failures such as belt aging and slippage and lowering long‑term maintenance workload. The touch‑screen control system visualizes operational status for convenient inspection and management by on‑site maintenance crews.
Energy‑saving retrofits for metro HVAC systems do not require large‑scale replacement of cabinet bodies or piping. The combined solution of fan upgrade plus intelligent control brings attractive energy‑saving returns, making it a preferred path for cost reduction and carbon mitigation of existing metro assets.
