Working Principle: The wet-membrane evaporative humidifier channels clean tap water to the upper water distribution system of the membrane via the supply pipeline. Gravity causes the water to flow downward along the membrane surface, fully wetting it. As dry air passes through the moistened membrane, its humidity rises while its temperature decreases, following an isenthalpic humidification process. During this operation, a portion of the water evaporates naturally, requiring no additional energy input.
Advantages: Good water absorption, high saturation rate, lightweight, low cost.
Advantages: Good water absorption.
Advantages: Poor water absorption, low saturation efficiency, but durable, non-rotting, and can be repeatedly cleaned.
Advantages: Same as aluminum alloy wet membrane.
