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.
