遠隔キャビネットの熱蓄積対策のための電気制御室換気プロジェクト

これ electrical control room ventilation project addresses a familiar problem in long, narrow rooms located inside a production building. The room contained a continuous row of control cabinets, while the only practical outdoor-air opening was near one end. During extended operation, cabinets closer to the remote end were surrounded by warmer air because fresh air did not travel consistently through the full room length.

The objective was not simply to add more wall exhaust. The project required a controlled airflow path that could bring filtered make-up air into the room, reach the remote cabinet zone and remove warmed air at high level without consuming the limited maintenance aisle. ポピュラ proposed a compact ducted arrangement based on HLF6 mixed-flow fan capability, subject to final heat-load and installation verification.

Problem scene: a single low-level opening near the entrance does not provide a defined airflow path to cabinets at the remote end.

Electrical Control Room Ventilation for Remote Cabinet Heat Build-Up

A single wall opening can leave a long control room with uneven conditions. Fresh air may serve the area closest to the opening, while warmer air remains around the far-end cabinets. This is especially relevant where cable trays, cabinet rows and restricted ceiling space limit the available route for a conventional large duct system.

The design therefore separates the intake and return functions. Filtered make-up air enters at low level near the accessible end of the room. A compact ceiling duct distributes supply air farther along the aisle, while a high-level return point at the remote end draws warmed air away from the cabinet zone. The final airflow and filtration arrangement should be coordinated with the cabinet manufacturer’s environmental requirements and the site’s dust conditions.

Why Use an HLF6 Mixed-Flow Fan in a Space-Constrained Layout

HLF6 mixed-flow fans are compact, low-noise units intended for low- and medium-pressure ventilation duty. The series offers a range of airflow and pressure options, with listed static-pressure capability up to 2,000 Pa across the range. This makes the product type suitable for evaluating compact ducted supply or exhaust paths where an axial fan may not provide sufficient pressure for the required duct route. Actual model selection must use the calculated airflow, external static pressure, available ceiling space and verified operating conditions.

How the Layout Solves the Airflow Problem

Locating the high-level return at the far end creates a defined direction for room air: low-level make-up air enters near the accessible side, travels along the cabinet line and is drawn upward and back through the return path. Ceiling diffusers or suitable outlets can distribute the supply path without placing large equipment inside the maintenance aisle. Fan equipment is positioned outside the occupied room or in an accessible service location, rather than obstructing cabinet access.

Solution scene: low-level make-up air, compact ceiling duct distribution and a high-level remote return create a more deliberate airflow path.

Practical Value for Maintenance and Expansion

The arrangement keeps the control-room aisle clear, supports access to filters and duct components, and provides a clearer basis for reviewing future cabinet additions. During commissioning, the project team should verify conditions at both near and remote cabinets, record the baseline airflow arrangement and confirm that make-up air remains appropriately filtered.
