Traditional data center cooling wastes energy. Cold air disperses randomly, bypasses equipment, and leaves hot spots that threaten server reliability. The Intelligent Air Flow Raised Floor from Huahong Floor solves this problem. This active cooling system integrates variable-speed fans and temperature sensors directly into standard 600×600mm raised floor panels, delivering targeted airflow exactly where servers need it.
An Intelligent Air Flow Raised Floor is an active cooling device that replaces standard perforated tiles in raised floor data centers. It consists of a ventilation grille, EC brushless fans, and an intelligent temperature control system. The unit mounts directly into a standard 600×600mm raised floor opening and connects to the underfloor air plenum.

Traditional perforated tiles release cold air vertically, creating a diffuse plume that often misses rack intakes entirely. Studies indicate 40-60% of supplied air can bypass equipment in poorly configured aisles.
The Intelligent Air Flow Raised Floor uses a closed-loop control system:
1. Sensors monitor exhaust air temperature at server rack rear
2. Control module calculates required cooling capacity
3. Fan speed adjusts automatically to deliver precise airflow
4. Cold air targets server intakes directly, not the room

Answer: The difference is active versus passive cooling. A standard perforated tile is a passive device – it simply has holes that allow cold air from the underfloor plenum to rise into the room. Airflow is uncontrolled; it disperses vertically in a diffuse plume that often misses server intakes, creating bypass airflow (40-60% of supplied air can bypass equipment). An Intelligent Air Flow Raised Floor is an active cooling device with its own EC fan and temperature control system. It monitors server exhaust temperature and automatically adjusts fan speed to deliver targeted airflow exactly where needed. This eliminates hot spots, reduces bypass airflow to 15-25%, and can increase sustainable rack density from 5-7kW to 8-12kW per rack. For data centers with medium to high-density cabinets, the intelligent system is far more effective.
Answer: The Intelligent Air Flow Raised Floor requires a minimum plenum height of 300mm (approximately 12 inches). The unit itself has an ultra-thin design of only 180mm total height. This fits within most standard raised floor installations. For comparison, traditional underfloor air distribution systems typically work with plenum heights of 300-450mm. The 300mm minimum makes this system suitable for both new construction and retrofit projects where plenum height may be limited. Before specifying, measure your existing raised floor void height. If your plenum is less than 300mm, contact Huahong Floor to discuss low-profile alternatives or underfloor ducting solutions.
Answer: The system uses a closed-loop control algorithm based on server exhaust temperature. Here is how it works. Temperature sensors located at the air discharge side of the server cabinet measure exhaust air temperature. The built-in control module compares this reading against setpoint values. If exhaust temperature is high (indicating insufficient cooling), the module increases fan speed to deliver more cold air. If exhaust temperature is low, the module reduces fan speed to save energy. This automatic adjustment ensures cooling matches demand precisely – no overcooling, no undercooling. The system can also be integrated with building management systems via the RS485 interface and MODBUS protocol for group control and remote monitoring.
Answer: Gradual deployment is a key advantage of this system. Unlike traditional cooling upgrades that require wholesale changes, the Intelligent Air Flow Raised Floor can be installed only where needed. For example, if you have a mix of standard-density and high-density server cabinets, install intelligent units only in front of the high-density racks where hot spots occur. Standard perforated tiles remain elsewhere. As your data center grows and densities increase, you can add more intelligent units over time. This scalability makes the system cost-effective – you pay only for the cooling you need, when you need it. For retrofit projects, this is particularly valuable because you can target problem areas first and expand the solution as budget allows.
Answer: Yes. The Intelligent Air Flow Raised Floor uses the same high-strength steel-cement substrate as standard raised floor panels. The uniform load rating is ≥1000kg (approximately 2200 pounds). This means server racks, UPS units, and other equipment can be placed directly on or adjacent to the airflow panels without structural concerns. Available load models range from FS1250 (567 KG concentrated) to FS2500 (1134 KG concentrated). For most data center applications, FS1500 or FS2000 models provide ample capacity. The ventilation grille is designed to support equipment loads without deformation. Always verify specific load requirements with Huahong Floor based on your equipment specifications.
Answer: Yes. Each Intelligent Air Flow Raised Floor unit includes a standard RS485 communication interface with MODBUS protocol* support. This allows integration with:
- Building Management Systems (BMS)
- Data Center Infrastructure Management (DCIM) software
- Centralized cooling control platforms
Capabilities include: group control of multiple fan units, status inspection (fan speed, temperature, fault conditions), remote setpoint adjustment, and alarm notification. For large data centers, this integration enables coordinated cooling management across dozens or hundreds of units. [Huahong Floor] provides protocol documentation and integration support.
Answer: Energy savings vary by configuration, but studies of precision airflow management show significant reductions. Directional and intelligent airflow systems can reduce fan energy consumption by 15-25% in retrofit installations. Savings come from three factors. First, improved ΔT (delta temperature) – when cold air reaches server intakes, servers absorb more heat per CFM, allowing CRAC units to reduce fan speed. Second, reduced bypass airflow – less cold air wasted mixing with room air instead of cooling equipment. Third, lower plenum static pressure requirements – because intelligent tiles deliver more effective cooling per CFM, facilities can reduce underfloor pressure from 0.08-0.12 inches to 0.05-0.08 inches water column. For a typical 500kW IT load data center, 20% fan energy reduction can save thousands of dollars annually. Request a cooling assessment from Huahong Floor for project-specific estimates.
