Adopt high-temp chilled water 13℃ In /18℃ Out，supply water temp ≥ indoor air dew point +1~2℃ → coil surface never below dew point, zero condensation, no drain pan required normally.
Humidity & latent load fully undertaken by outdoor fresh air MAU unit; dry coil only removes sensible heat from server rack waste heat (IT chip, PSU heat).
Matches Hot/Cold Aisle Containment closed airflow:
Cold aisle containment: coil mounted ceiling above cold aisle, blow cool air down into rack inlet
Hot aisle containment: coil fixed at hot aisle ceiling, suck high-temp exhaust air from rack outlet for direct sensible cooling
Air temp typical: return air 32~36℃ → supply air 22~26℃ after coil cooling, ΔT≈10℃ standard.
Component | Material & Design Feature |
|---|---|
Heat exchange tube | TP2 seamless copper tube OD9.52/12.7mm, wall≥0.45mm; optional SUS304 stainless tube for edge/chemical corrosive IDC |
Fin | Hydrophilic epoxy coated aluminum fin; wide fin pitch (3.2~4.2FPI), less dust clogging for data center dusty air |
Header/Manifold | Carbon steel with anti-rust coating / SUS304 stainless; full argon arc welding, factory hydraulic pressure test (1.5×WP for 24h leakage check) |
Frame | Galvanized steel / SS304 frame, anti-vibration structure for ceiling suspension |
Auxiliary | Auto air vent + drain valve on water inlet/outlet; optional small backup drip tray for abnormal high-humidity emergency use |
Air Side
Face velocity: 1.0~2.0m/s (optimized for closed aisle circulating airflow)
Air resistance: ≤90Pa, match EC ceiling fan/FFU static pressure design
Tube rows: 2/3/4 rows customizable (2row: low density rack; 3~4row: AI/HPC high-density >15kW/rack)
Water Side
Design chilled water: 13℃ IN /18℃ OUT (standard)
Water flow velocity: 0.9~1.5m/s, counter-flow layout to maximize sensible cooling efficiency
Single coil cooling capacity range: 5kW~180kW per unit, modular combination for large hyperscale IDC
