Can FFU rated power directly represent actual power consumption?

Straight answer: no. The unit of rated power is usually watts (W), which represents the power parameters of the device under specified conditions; the unit of actual power consumption is kilowatt hours (kWh), and the actual input power and operating time of the FFU in different modes need to be considered. Rated power can be used for preliminary estimates but is not a direct substitute for on-site power measurements.

The three numbers should be viewed separately

For example, assuming that an FFU continues to operate at an actual input power of 150 W for 24 hours within a certain period of time, the power consumption in this period is 0.15 kW × 24 h = 3.6 kWh. The 150 W here must be the actual input power under this working condition; just seeing that the product is marked '150 W' does not mean it consumes 3.6 kWh every day.

Why might the field power be different from the rated value?

FFU may be set to work, duty or zone speed regulation mode, and the actual input power at different speeds will change. Filter resistance, top air inlet conditions and target air volume will also affect the operating status of the fan. If the control scheme adjusts the rotation speed to maintain air supply, the power of the filter after being used for a period of time may be different from the initial installation state, which needs to be confirmed through measurement.

In addition, the project should explain the power statistical boundary: is the input of a single FFU machine or the motor data measured? Whether supporting equipment such as group control cabinets and gateways are included in the total power of the system. Figures at different boundaries are not directly comparable.

How to calculate power consumption for batch FFU projects?

You can first agree on the target air volume and filter configuration in the technical agreement, and then measure the FFU complete machine input power and actual operating time in each operating mode. The preliminary calculation can be based on ' average input power of each mode × corresponding operating time ' and calculated separately and then summed; if the power changes greatly with time, it should be based on the accumulated readings of independent electric meters.

When it is necessary to compare the power consumption before and after the transformation, the number of FFU, air supply target, operating time and statistical boundaries should also be unified. The power saving ratio cannot be directly calculated solely based on the AC, EC or DC motor type or the rated power in the product catalog. Multiple partition projects can be combinedAili Industrial FFU group control system records the operating mode and configures the power statistics interface according to project requirements.

How does Aili Industry cooperate with energy consumption assessment?

Aili Industrial develops and produces motors, fans, control systems, sheet metal structures and filters in-house. SureWhen configuring the FFU complete machine , the target air volume, filter resistance, common rotation speed and corresponding input power can be checked at the same time to establish a basis for comparison under the same working conditions for project budget and subsequent measurement.

Before technical communication, it is recommended to provide the number of FFU, operating time, work and duty mode, target air volume, filter requirements and power consumption statistical range. The final actual power consumption is based on the project operation records and the power measurement results under the agreed boundaries.
