Working principle

● 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
● 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.
● Various functional sections such as filter section,
cooling/heating section, humidifying section etc.
can be combined together to meet different air
treatment requirements.

Judging left or right type

Look at the direction of airflow supplied to indoor, it’s left type if water pipes are located on the left side of the unit;otherwise, it’s a right type. For standard AHU, service door, wiring port and water pipe locate on the same side.

Main features

● Up-down layer construction, concise, compact.
● Rotary heat exchanger(RHE) as a basic part. Humidifying section, coil section etc. selectable as per requirements.

Combination :RHE + coarse/medium filter + mix air + cooling/heating coil + fans

Rotary heat exchanger (heat recovery wheel) is mainly used in building ventilation or in the air supply/discharge system of air conditioning equipment. The wheel transfers the energy (cold or heat) contained in exhaust air to the fresh air supplied to indoor.It’s a piece of important equipment and a key technology in the field of construction energy saving.

Rotary heat exchanger section

1. Rotary heat exchanger is composed of heat rotor(wheel), frame, drive system, double purge sector and sealing parts etc..
2. Supply air(SA) passes through half of the wheel, exhaust air(EA) passes through reversely the rest half of the wheel, meanwhile the wheel is rotating driven be the drive system. Thus, the wheel can be self-cleaning.
3. Drain pan is equipped under the wheel, in case condensed water occurs from fresh air in summer or return air in winter when their temperature is decreasing. Meanwhile, make sure the drainpipe is expedite and waterseal is installed.
4. Ice jam might occur on the exhaust side when operating in very cold area, if so, rotary speed reduction or turn-on of bypass is required to ensure safe operation of the wheel.
5. On some occasions with strict cleanness requirement, to minimize the carryover from return air to supply air,exhaust fan shall be placed in the leaving section of the exhaust side to create passive pressure, and the pressure shall be lower than that of supply side, so that the double purge sector can perform more effectively.
6. For easy transportation or easy installation in limit space, the wheel can be cut into segments.


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..

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.
