IEC 60879 Tower Fan Table Fans Energy Efficiency Performance Test Chamber

IEC 60879 Tower Fan Table Fans Energy Efficiency Performance Test Chamber

Standards Application:

IEC 60879-2019 "Comfort fans and regulators for household and similar purpose- Methods for Measuring Performance "

System Overview:

This test system can accurately measure the performance parameters such as the wind speed, air volume, fan speed, fan power consumption, and fan energy efficiency of table fans, floor standing fans, pedestal fans, etc., and can realize the sampling and analysis of fan products, product quality inspection, and research and development.

This test device adopts single chamber structure. The laboratory contains one set of air volume measurement device. The test room uses 50mm thick rigid polyurethane board and 0.6mm thick color steel plates on both sides for thermal insulation, which has good thermal insulation effect.

The 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 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, which is constructed by the buyer (generally next to the laboratory).

This test system is mainly controlled by computer. The operator is outside the test room, and the personnel will not affect the wind field. 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.
