Common Issues, Causes, and Solutions for Modular Air-Conditioning Unit

2025-06-01

Modular air-conditioning units are widely used due to their versatility, but they can experience issues like water leakage and dripping. These problems often stem from air

leaks, poor drainage, high humidity, or improper operation.

Common Issues and Causes:

Condensation at seams and corners: Caused by air leaks leading to temperature differences.
Water accumulation at the bottom: Due to poor drainage or insufficient water seal height.
Leaks at condensate pipes: Often caused by pipe damage.
Water droplets on external surfaces: Result of high humidity and temperature differences.
Water splashing inside the unit: Caused by high air velocity.
Water on inner walls after humidification: Due to continued humidification after the fan stops.

Solutions:

Seal air leaks: Identify and seal gaps with sealant.
Clear water accumulation: Ensure proper drainage by fixing or cleaning the water pan and drain pipes.
Adjust water seal height: Ensure it is sufficient to prevent negative pressure issues.
Control humidity: Improve ventilation or add insulation to reduce condensation.
Adjust air velocity: Reduce air speed by adjusting the fan settings or adding deflectors.
Control humidification: Stop humidification when the fan is off and ensure proper mixing of humidified air.

By addressing these issues promptly, users can maintain the efficiency and performance of modular air-conditioning units.
