Selection Table of AHU

air handling unit design

 

Working principle

1/Both supply fan and exhaust fan are built inside tobring 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.

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

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

 

Typical Combinations

Combination mode 1:
Wheel + Coarse filter (medium filter) + Cooling coil (heating coil)+ Humidification + Fan

Combination mode 2:
Plate heat exchanger + Coarse filter (medium filter) + Mixed air +Cooling coil (heating coil) + Fan

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.

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..

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.

FAQ

1.How we can fast make AHU selection and its solution according to project need?
Holtop has a extensive working experience team on all kinds of AHU solution for any building air quality control no matter project private house or industrial factory. First of all, we need to know the AHU service place, and the room size(it’s could better if AutoCAD drawing is available), as well as the local climate data.

2.What it’s the main feature of Airwoods/Holtop’s air handling unit?
:More than 15 years on manufacturing and development air handling unit with air to air heat recovery devices. Strictly design and produce according to GB/T 1429-2008 and ISO approved quality control with strong team of AHU engineer guarantee quality and performance perfect meet thermal bridge factory TB2, mechanical strength D1 and thermal transmittance T2(En 1886-2007) and air leakage ratio 0.94%(GB/T1429-2008)


3.What successful project your AHU service for?
Airwoods/Holtop AHU has been successful use in the Auto-industrial(Benz, General motors, Geely motors, Greatwall motors,Chery motors etc ), printing factory, green house, mall etc. Our goal is to help you find the high efficiency, low running cost, high performance HVAC solution both in field of commercial and industrial.

 

4.What it’s your delivery time and package?
It’s takes 3 week working day for normal AHU production. Package should suitable for ocean shipping and well protection for AHU with plywood case.
