Heat Recovery Chilled Water Air Handling Units

Seaworthy wooden cases

Specifications

Introduction of Air Handling Unit,

1) Vertical or Ceiling type

2)Multi-functional
3)Heat recovery functions (Eurovent Heat Exchanger)
4)Excellent thermal insulation
5) Airflow 2000~100000CMH

Main features
1) Equipped with supply fan and exhaust fan, brings in fresh air and exhausts out stale indoor air as well.
2) Equipped with rotary heat exchanger, recovers energy from outgoing indoor air, to save operating cost to the max.
3) Thin height, easily installed in the ceiling space.

Housing construction
1) Double skin panel
25mm thick, inner skin made of galvanized steel sheet, outer skin color steel sheet, between skins is sandwiched with high density fireproof PU with thermal coefficient below 0.0199W/m Degree.
2) High air tightness
Double inlaid sealing system to tightly join the framework and panels, total air leakage rate below 3%.

Supply fan and exhaust fan
Outer rotor motor, direct driven centrifugal fan, dynamic balance, compact and low noise level.

Filter
Plate type(G4) coarse filter as standard configuration. (Bag filter F5~F8 available as per request of customer). Draw-push installation, easy maintenance.

Eurovent Rotary heat exchanger
Holtop total heat exchanger (enthalpy recovery wheel) is made of aluminum foil coated with 3A molecular sieve, which enables the wheel to exchange both temperature and humidity, in another word, to recover both sensible and latent heat.

Operation and maintenance
1. AHU is powered by TN-S power supply system, i. E. AC3~380V+N+PE.
2. Check and make sure motor runs at right direction and freely. Run the unit after all the electric parts are checked without fault by a professional.
3. Commissioning is required before putting the equipment into use. Motors should be running under rated electric current.
4. Cooling & heating coil should use clean demineralized water as medium, working pressure ≤ 1.2MPa.
5. Drain out the water in the coil in winter, and blow away the remains water as far as possible. In case remains water can not be blew away, inject antifreeze into the coil.
6. Examine the filter regularly, clean or replace it if resistance comes to the end resistance. Air-dry the washed fil- ter totally before reuse.
7. Fully clean or maintain the unit after each 1 or 2-year operation. Clean the coils using compressed air or high pressure water.
