The dual‑source fan wall integrates EC permanent‑magnet fan matrix with dual heat‑exchange units: chilled‑water coil and air‑side free‑cooling module.
Multiple EC fans feature independent stepless speed regulation. The system automatically switches cooling modes based on outdoor ambient temperature: chilled‑water cooling for high‑temperature periods and free‑cooling in cold seasons, greatly shortening the operating hours of chillers.
The system adopts N+1 fan redundancy. Cooling supply will not be interrupted even if one single fan fails, which effectively eliminates local hot‑spots.
Modular assembly structure supports in‑situ retrofit and phased capacity expansion. It can connect to environmental monitoring platform to realize intelligent cooling capacity regulation.
The cabinet is optional in galvanized steel or stainless steel for long‑term continuous‑operation conditions. Widely applied in high‑energy‑consumption computer rooms and large‑space constant‑temperature sites, it is an efficient HVAC solution for PUE reduction.
