Temp. 76±2°F Humidity 50% Energy Efficiency Test Lab Of ENERGY STAR Qualified Ceiling Fans
Temp. 76±2°F Humidity 50% Energy Efficiency Test Lab of ENERGY STAR Qualified Ceiling Fans
Overview:
The ceiling fan energy efficiency test conforms to the standard of " Building a Testing Facility and Performing the Solid State Test Method for ENERGY STAR Qualification of Ceiling Fans ".
The test system adopts IPC computer control, and the equipment testing work is completed automatically. The test data is recorded, saved, and the air volume report and energy efficiency rating are generated automatically. The data is accurate, good repeatability, high efficiency, and convenient to be stored. The test system is driven by a servo motor to ensure that the test process runs smoothly; the wind speed is measured with an imported precision anemometer; the console is placed outside the test house, ensure that the operator will not affect the wind field.
Standards:
Can be designed according to the following standards:
► Building a Testing Facility and Performing the Solid State Test Method for ENERGY STAR Qualification of Ceiling Fans
► Other standards
