Cold Aisle Cabinet

It encloses the cold aisle between cabinet rows so cold and hot air are fully isolated, with no turbulence or airflow short-circuiting. Cooling efficiency rises well above single-cabinet levels, equipment density increases, less floor space is needed, and energy consumption drops by up to 30%.

The enclosed aisle is 1200 mm or 1800 mm wide. A single-row module holds ⁦3–24⁩ cabinets and a double-row module ⁦6–40,⁩ with a total length under 15 m including air conditioners. Cabinets are 600 or 800 mm wide, ⁦1000–1200⁩ mm deep and 2000 or 2200 mm high, providing 42U or 47U of usable space.

In-row or room-level air conditioners, either direct-expansion (air-cooled) or chilled water. In-row units use variable-frequency compressors and EC fans with horizontal airflow, sized 300 × 1200 × 2000 mm or 600 × 1200 × 2000 mm; room-level units use fixed-frequency compressors with underfloor air supply.

The system runs on 380/400/415 Vac, 50/60 Hz, 3Ph+N+PE. A modular UPS of ⁦20–250⁩ kVA can be configured N, N+1 or 2N with at least 95% efficiency and online hot-swap maintenance, and batteries are installed internally or externally. Rack PDUs mount vertically at the cabinet front or rear, and the distribution cabinet adds Class C surge protection, a 10-inch display and branch-circuit monitoring.

A fire-rated skylight in the aisle roof opens under gravity, allowing the gas fire-suppression system to discharge directly into the cold aisle area — safe and reliable. Fire linkage includes sound-and-light alarms, smoke sensors and temperature-humidity sensors.

The enclosed track-mounted double doors open by remote control, card, password or sensor. The monitoring system covers centralized management, access control, video surveillance, asset management and battery monitoring, accessible via remote web, a local 10-inch touchscreen or an optional mobile app, with alarms pushed by WeChat, SMS, email and phone.
