Testing plan

1. Test sample: Single split type room air conditioner; three interchangeable special air volume indoor unit fan (85% ±3%, 80% ±3%, 65% ±3%). Special air volume fan: Add obstructions onto the fan to simulate the impact of dust accumulation on the air volume, the air volume is measured through the enthalpy different laboratory.

2. Special air volume indoor unit fan treatment: Add obstructions on the middle of fan to achieve the purpose of affecting the air volume. The associated test design, covering area (Permissible Error ±0.2%), and treated fan air volume (Permissible Error ±30) are shown in the table below:
