How to measure the indoor air wet and dry bulb temperature difference1. Attach at least 2 sets of wet and dry bulb thermometers to the indoor air intake as shown in the figure, and at least 2 sets
of wet and dry bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where airspeed is high.
2. Attach at least 2 sets of wet and dry bulb thermometers to the outdoor air intake.Cover the thermometers to prevent direct rays of the sun.
3. Check that the air filter is cleaned.4. Open windows and doors of room.5. Press the EMERGENCY OPERATION switch once (twice) to start the EMERGENCY COOL (HEAT) MODE.6. Compressor starts running at 33 Hz (COOL) or 45 Hz (HEAT). The frequency at each operation mode is fixed.7. When system stabilizes after more than 15 minutes, measure temperature and take an average temperature.8. 10 minutes later, measure temperature again and check that the temperature does not change.
