It was later discovered that the fan inverter's startup ramp was set too steeply, resulting in uneven airflow distribution. My current commissioning process is: first, start the circulating water pump and run it for 30 minutes. Observe the water level in the collection pan for stability (normal fluctuation range: ±5mm). Then, gradually increase the fan speed. Simultaneously, use an infrared thermometer to monitor the temperature difference between the inlet and outlet water of the coils. High-quality equipment should maintain a steady temperature difference of 5-8°C.
