Core Process: Refrigerant evaporates and absorbs heat inside the tubes, lowering the fin surface temperature below the air dew point. As humid, hot air flows through the fins, water vapor condenses into water droplets that fall into the collection tray.
Heat Exchange Path: Air (shell side) → Fins → Copper Tubes → Refrigerant (inside the tubes), achieving efficient heat transfer.
Base Tube (mainly copper):
Specifications: φ9.52/12.7mm, wall thickness 0.5–0.8mm, good thermal conductivity, pressure resistant.
Alternatives: Stainless steel (corrosion resistant), titanium tubes (high humidity/salt spray environment).
Fins (mainly aluminum fins):
Form: Open/corrugated fins (enhanced turbulence, improved heat exchange), hydrophilic coating (accelerates drainage, reduces "water bridges").
Spacing: 2.0–2.5mm (dedicated for water treatment, balancing heat exchange and drainage; too narrow and it's prone to clogging and high air resistance; too wide and efficiency is low).
Thickness: 0.15–0.2mm, lightweight and strong. Selection Recommendations:
High Humidity Environments (RH>70%): Prioritize 2.0–2.2mm fin spacing + hydrophilic coating to enhance drainage.
Dry Environments (RH<60%): Appropriately increase fin spacing (2.5mm) and heat exchange area to improve condensation efficiency at low temperatures.
Low Temperature Environments (<10℃): Add a defrosting circuit to prevent icing and fin blockage.
