Working principle of Air Handling Unit, Energy Saving, Fexible Combination

1. Both supply fan and exhaust fan are built inside to Bring in fresh air and exhaust out the stale indoor Air as well, thus to keep indoor space in natural Comfort.
2. Built-in heat exchanger (rotary heat exchanger or Plate heat exchanger) transfers energy contained in The outgoing indoor air to the coming fresh air, Thus fresh air is precooled or preheated.
3. Various functional sections such as filter section, Cooling/heating section, humidifying section etc. Can be combined together to meet different air Treatment requirements.

Housing construction features

1. Double skin panel
Double-skin panel sandwiched with high density PU foam, thermal conductivity below 0.01999W/m· Degree, insuring high performance between -40 Degree and +70 Degree.
2. High mechanical strength
Galvanized sheet inner skin, color steel sheet outer skin, strong steel framework, pressure endurance up to 2000PA, suitable for large air application.
3. High air impermeability
Double inlaid sealing to join the frameworks and panels tight, minimizing air leakage.
4. Flexible combination
Designed with 102mm modulus, frameworks and panels are flexible to change according to design Requirements.

Housing series

08A: 25mm thick panel of floor AHU, suitable for 2000~40000CMH.
08B: 40mm thick panel of floor AHU, suitable for 10000~50000CMH.

Selection of rotary heat exchanger and plate heat exchanger

Plate heat exchanger (PHE) simple construction, safe operation, drive free, good air tightness, cross contamination free. But large spacing taken up, not suitable for large airflow.
Rotary heat exchanger (RHE) compact construction, high recovery effectiveness, less spacing taken up, driven power required, suitable for large airflow. Not suitable for occasions of injurants or toxicant due to its small cross contamination.

Water cooling/heating coil

HJK AHU adopts heat exchange coil made from copper or aluminum fins and copper pipe. Copper pipe is expanded mechanically and aluminum fin is double-side bended in wave type. It is featured by high coefficient of heat thermal coefficient, low air resistance, compact structure and excellent performance resulted from the advanced structure, reasonable water path, pipe length and fin gap. Low-temperature and fast braze welding on copper pipe reinforces its pressure resistance over 1.2Mpa.

FAN SECTION

We offer different types of fans such as direct driven centrifugal fan, belt driven DIDW forward centrifugal fan, and belt driven DIDW backward centrifugal fan etc...

HUMIDIFYING SECTION

Wet film humidifier, dry steam humidifier or double gasified humidifier is available for choice.

Wet film humidifier
It utilizes spontaneous evaporation of water on the film face to humidify the air, water supply is 3 times the humidifying capacity. It is featured by low requirement on water, simple structure, easy installation and long service life.

Dry steam humidifier
Suitable for occasions where steam is available. It use nozzle humidifying method for small airflow and steam quick absorption humidifying method for large airflow.

Double gasified humidifier
This system incorporates the stress spray humidifying technology and wet-film humidifying technology in an effective way. It makes better humidifying, consumes less water and makes better cleanness.

Air filter
In order to ensure heat exchanging efficiency and cleanness, combination of G3 coarse filter and F5 medium filter is selected as standard configuration in HJK AHU.
