Test Chamber
Overview
This test laboratory can perform the performance test of the fans in accordance with the methods specified in IEC 60879-2019.
The test system can accurately measure the performance parameters such as the wind speed, fan speed, fan power consumption, fan energy efficiency value of ceiling fans and decorative ceiling fans, and can realize the sampling and analysis of fan products, product quality inspection, and research and development requirements. It is a comprehensive single enthalpy difference chamber.
The test chamber uses 100mm thick rigid polyurethane board and 0.6mm thick color steel plates on both sides for thermal insulation, which has good thermal insulation effect. This test room contains an external air conditioning system, which is used to adjust the air environment inside the test room. The indoor air is cooled, humidified, and heated to make the temperature and humidity in the test room meet the requirements of the test conditions.
This laboratory needs to be equipped with an operating room for storing office computers, power cabinets, control cabinets, and variable frequency power supplies. This house can be constructed by boards. This test system is mainly controlled by computer. The test of the equipment is completed automatically, and the test data is recorded, saved, and the air flow report and energy efficiency rating are automatically generated. This system has advantages of good repeatability, high efficiency, convenient data storage and so on.

Ceiling Fan Test Principle and method :
- First, install the ceiling fan through the iris opening to fit sample size using its own remote control, the anemometer device below 1500mm from the fan blade plane.
- Before testing, it is also necessary to close the air inlets and outlets, doors and windows, and relevant personnel to leave the laboratory to ensure that the laboratory is not affected by external airflow. Then operator runs the anemometer to start collecting anemometer parameters. The anemometer device is rotated by 90 ° per minute to collect and record data (wind speed, speed, etc.) under the action of the rotating drive frame. (The data of wind speed ≥9m / min tested in all anemometers is valid data). The laboratory is equipped with a regulated power supply, which can reduce the impact of mains fluctuations on test measurements. Fan power voltage current is measured by a 0.5-level power meter.
