Test Procedure

Pre-Test: Confirm ambient temperature and humidity conditions (32 °C, 60% RH). Record baseline ambient temperature. Prepare 3 samples (B7-1#, B7-2#, B7-3#) and connect to 120 V power source.
Procedure: Operate each unit continuously with both large and small nozzles attached. Monitor and record temperatures at four measurement points — motor, internal air duct, large nozzle, and small nozzle — until readings stabilize (temperature rise plateau reached).
Post-Test: Record the maximum temperature (°C) and temperature rise (K) at each measurement point for each sample. Ambient temperature at time of test is noted per sample.
Acceptance Criteria: No formal pass/fail threshold specified (internal reference standard). Results are recorded for reference only (供参考).

Frequently Asked Questions

What does temperature rise (K) mean in this test?

Temperature rise, expressed in Kelvin (K), is the difference between the maximum measured temperature at a given point and the ambient temperature recorded during the test (33.5 °C in this case). It isolates the heat generated by the product itself, independent of the starting ambient condition, making it a reliable metric for comparing thermal performance across different environments.

Why are the results marked “For Reference Only” rather than Pass or Fail?

The test was conducted against an internal control standard with no defined numerical pass/fail threshold for temperature rise. This is common in early-stage engineering validation or design characterization testing, where the goal is to map thermal behavior rather than certify compliance against an external standard such as IEC or UL.

Why were both large and small nozzles tested simultaneously?

Different nozzle sizes affect airflow restriction and therefore motor load. Running both configurations ensures the thermal profile captures the worst-case operating scenario. Results at the large and small nozzle measurement points reflect how nozzle geometry influences heat distribution along the airflow path.

How do the three samples compare?

B7-1# ran coolest overall, with a peak motor temperature of 75.2 °C and motor temperature rise of 41.7 K. B7-2# and B7-3# were close, peaking at 80.1 °C and 80.8 °C respectively. Sample-to-sample variation of approximately 5.6 °C at the motor is within a normal range for this class of product and likely reflects minor manufacturing tolerances in motor winding and housing fit.
