1.0 INTRODUCTION
The Double Skin Modular Air Handling Unit is designed based on modular paneling concept to fulfill the
indoor air quality requirement. The air flow of DM AHU is within range of 330 to 20,000 lps (700 to 42379
CFM) and up to a total static pressure of 1991 pa (8 W.G). For special design, the air flow can be reached
25,000 lps (52974 CFM).
The AHU is constructed of high strength extruded Aluminium to form rigid frame. Beside, it is with
thermal barrier feature which using three leg-fiber plastic corner pieces, 25 or 50 mm Polyurethane (PU)
insulation panel and all frames are insulated with 3.0 mm PE foam to minimize energy heat loss and
prevent condensation occurring. The external clip method to hold the double skin PU insulation panel is
easily accessible for maintenance while being air tight. The new thermal- break profile can perform better
than the original profile in terms of providing better insulation and energy saving.
There is selection software programme available: DM AHU, to optimize the best arrangement and
performance for either chilled water system or DX system. Standard components can be selected and
be placed according to customer requirement. Once the unit is defined, optional item and accessories
are identified. The programme gives immediate feedback if there is no suitable choice for the units. The
programme provides us with fan curves data, coil performance data, dimension, and shipment weight.
McQuay can produce high quality, flexibility air handling unit which can provide excellent thermal
efficiencies and to be airtight. Besides, air handling unit produced is with flexibility features to meet the
indoor air quality, operating efficiency, sound level and installation requirement for todays extensive
commercial and custom markets. A comfortable environment can enhance humans life quality.

3.7 FAN
Fans are used extensively in air-conditioning for circulating air over coils. The fan type includes forward curved,
backward curved, twin fans and airfoil fans with double width double inlet (DWDI) centrifugal fan. The first
low cost option will be forward curved fans which are generally used for low static pressure applications.
The blade of fan is constructed of galvanized steel. It consists of blade which has tips curving forward that is in
the direction of rotation of fan wheel. In addition, it generates low noise level which is preferred for
installation in AHU.
Meanwhile, for backward curve fans, it requires higher speed and therefore has to be more sturdy in
construction. The blade of backward curved is made of heavy gauge steel or mild steel, painted after
manufacturing. It can handle high static pressure system and able to show higher efficiency over a broader
range of higher system resistance.
For aerofoil fans, normally it will be the last option due to the costly components. It is constructed of mild steel.
However, it shows higher efficiency, generate low noise level and can handle higher static pressures. McQuay
housed air foil fans can operate up to 2240pa of static pressure.
Fan performance of all these fans have been tested and measured in accordance to AMCA Standard 210. The
sound level is measure and rated in accordance with AMCA Standard 300. The fan bearing provided will have
a minimum L50 life of 200,000 hours, and are available as high as 1,000,000 hours. Bearings are selected for
minimum noise level and minimal device. The bearing is lubricated for life and maintenance free. Relubrication
is optional. Fan is dynamically and statically balanced to Standard ISO 1940. The fan shaft is manufactured
from C45 carbon steel. It is coated with a layer of anti-corrosion varnish.
There are two discharges direction: vertical and horizontal discharge. The fan discharge should be square (for
both forward or backward curved fans) in area and flanged and isolated from the casing by the fire retardant
grade flexible connection. Only one fan discharge is provided.
Fan selection requires accurate calculation of the air flow resistance through the whole system consisting of
the total of two parts; external and internal static pressure. External static pressure is found in the distribution
system, external to the air handler. Internal static pressure is the sum of the resistance of the coils and others
component and accessories. Use the DM AHU selection Software to determine internal component pressure
drops of the system. The software identifies fans available to properly handle the air flow and static pressure
for the system.

3.8 MOTOR
Motor is internally mounted integral to an isolated fan assembly. Standard motor shall be horizontal foot
mounting, induction motor, squirrel, totally enclosed fan-cooled (TEFV or TEFC) with IP 55 protection with
class F. Motor capacity cannot be undersized but oversized for desired running capacity. For the desired
operation speed between fan and motor, there are a few types of motor poles: 4 and 6 poles.
Motor Option
380-415 Volt / 3 phase/ 50 Hz ( standard)

3.14 HUMIDIFIER
There are a few humidifiers are used commercially in AHU. We install electrode steam humidifier, which is
categorized as BFDT series, the second generation, high precision, intellectualized electrode humidifier. It
requires an empty section to be installed. It is a device which is used to increase the air relative humidity in
atmosphere without steam source. It is a constant temperature humidifier. Its principle is the common
electrode humidifier regulates the generated steam by the way of controlling water level and electrical current.
Electrical loop will be built up through salt minerals in the water. Therefore, water will be heated up and boiled
until vapor is generated continuously. Quality of water in the region must be considered because it reduces the
steam capacity. (Softened water cannot be used)

6.3 Ductwork
Good ductwork layout will minimize system resistance and sound generation. Duct connections to and from
units should allow straight, smooth airflow. Sharp turns in the fan discharge should be avoided, particularly
turns opposed to wheel rotation. Turning vanes should be used. Discharge plenums or any abrupt change in
duct should be avoided.

The system curve is unique for a particular system configuration. Any change to the system caused by dirty
filters, damper change, etc., will result in new system curve.
For fans operating at low pressures (less than 10 W.G.), the effects of air compression allows fan operation in
a fixed system to be expressed by simple relationships. These relationships are known as fan laws and may
be used to calculate the effects of fan speed and air density changes on this system.
1. The flow rate varies directly with the change in fan speed:
CFM1
CFM2
RPM1
RPM2
CFM2 = CFM1
or
A 10% increase in fan speed will give a 10% increase in air quantity.
27
RPM2
RPM1
2. The static pressure varies as the square of the change in fan speed:
SP1
SP2
RPM1
=
RPM2
or
SP2 = SP1
RPM2
RPM1
A 10% increase in fan speed will give a 21% increase in air static pressure.
3. The fan brake horsepower varies as the cube of the change in fan speed:
HP1
HP2
RPM1
=
RPM2
or
HP2 = HP1
A 10% increase in fan speed will give a 33% increase in fan horsepower.
RPM2
RPM1
4. System static pressure and brake horsepower are directly proportional to the air density:
RPM2
RPM1
SP2 = SP1
Density2
Density1
RPM2
RPM1
HP2 = HP1
Density2
Density1
Consequently, the static pressure and brake horsepower decrease with an increase in air temperature or
higher altitude, and increase with a decrease in air temperature or lower altitude.
To determine fan performance for temperatures and altitudes other than standard (70F, 0 ft. altitude), the
static pressure must be adjusted by the density ratio before the fan RPM and BHP requirement can be
determined. Density ratios are expressed as temperature and altitude conversion factors in Table 13.

DM Air Handling Unit comes standard with taper lock pulley and wedge belt with optional adjustable pulley
and belt.
Standard service factor of 1.5 suitable for 24 hours operation.
9.1 PULLEY ALIGNMENT
Adjust the motor pulley to align with the fan pulley with the use of a straight edge.
Do not force belts on the pulleys groove.
Firstly, loosen the bolts at motor base until belt can slide smoothly over pulleys edge.
When all the belts are in place, proceed to adjust belt tension using the adjusting nuts on the motor mount.
Use a recognized belt tension gauge to check the tension as shown in Table 18.
Figure 23 illustrates the pulleys alignment.

To check the belt tension, apply a force K large enough at the centre of the belt to deflect the belt 15mm
per meter. The deflection force for any belt should be within the minimum and maximum force shown in
Table 18.
When the tension drops to the minimum value, readjust to the maximum value.
During normal operation a belt seat itself in pulleys grooves and require periodical checks to maintain
tension.

WARNING: Improper pulleys alignment and belt tension are the most frequent causes of excessive
vibration as well as shortened belt and bearing life. It is important to install the pulleys as close as practical
to the bearing.
CAUTION: Do not over tighten the belts or the bearings may become damaged.

The DM Air Handling Units can be used for both chilled water system and direct expansion system application.
Coils are designed based on application to best meet the requirements.
Standard Aluminium fins are maximum 12 FPI (fin per inch). Copper fins are also available as option.
Fin thickness is 0.127mm and fin hardness is H0 and H22 for standard aluminium fin and others fins
respectively. Fins can be coated by Heresite or Hydrophilic fin material as a corrosion protective layer.
Standard coil frame is in 1.5mm thick galvanized steel (GI) while stainless steel (SSTL) is available as an
option when copper fin is used to avoid galvanization effect. Coil casing is designed to have drain holes at
the bottom channels to insure condensate drainage.
For water system, the coil is available in 1, 2, 3, 4, 5, 6, 8, 10 and 12 rows. Header and collar is constructed
of steel with copper material as the option. Its size is either 42 or 76 mm. Piping connection is only one
sided, either left or right, viewing from return air side. The connection for steel header is by Male Pitch
Threaded (MPT) joint. Copper header connection will be brazed joint but there is option with MPT by braze
connector.

For a direct expansion system, the coil is available in 2, 3, 4, 5, and 6 rows. TXV valve is optional item.
Header is only available in copper materials. Pipe connection is by brazing joint.
The standard working pressure of the coil is 250 psig (17 bar). Higher working pressure of 300 psig
(20 bar).
Coil surface area is standard size for each model and it is common for chilled water and direct expansion
coil type. (Please refer Table 19.)

AHU with heat wheel cannot be selected by DM AHU selection software as other standard unit because it is
categorized as special customized unit. It consists of two sections: return air side and supply air side. The
arrangement is as below. To install the heat wheel in air handling unit, an empty section is required. The size
of heat wheel has to be considered for the specification drawing. Besides, spaces between heat wheel section
and the coil section must be considered to ensure the most efficient heat transfer between air flow and coil
medium at the coil section.
