System Effect
Mr Prachanart Neamnam, Marketing Manager, Kruger Ventilation Industries (Thailand)
Abstract
Very often fan users will encounter the issue where the fan capacity and pressure are
different from the desired or designed. The differences in the performance are not
always clear and may be very difficult to deal with. Most of the time this is the result of
fan System Effect. AMCA’s resource, specifically AMCA 201 Fan and System and the
field experience of engineers in the HVAC industry serve as a guide to resolve issues
on System Effect. The reasons for System Effect to be causing frustration to all fan
users will be discussed.

Fan Selection – Fan Type and Fan Sizing
Mr Teoh Jye, General Manager of Marketing, Kruger Ventilation Industries Asia
Abstract
Ventilation system designers specify their requirement in terms of air volume flow rate,
static pressure and total pressure. With all these information, fan selection can begin by
selecting the fan type. There are centrifugal fans, axial fans and mixed flow fans, how
do we decide on what fan type? After deciding the fan type, then how do we decide the
proper or right size fan? In most cases, there are always more than one size of fan that
can meet the requirement with different fan speeds, power consumption, efficiency and
noise. Do we always choose the fan with the best efficiency or the fan with the lowest
noise? This may not be the right answer then how do we decide?

Development of EC Motor Technology & Application in Demand Ventilation
Mr Mike Hurrie, Consultant, Systemair Group
Abstract
The ability of fans to vary airflow is important both to allow improved control of
ventilation (makeup air) as well as to reduce fan energy consumption and overall
system efficiency. Electronically commutated (EC) motors are the current topic of
interest and they look set to replace traditional AC motors in fan drives. How EC
technology works will be covered and illustrations on their benefits in application will be
discussed.

Plenum Fan & Multiple Fan System
Mr Thomas Bader, Ziehl‐Abegg SE, Head of Product Management Centrifugal Fans
Abstract
Existing and upcoming regulations and energy saving programs demand high efficient fan systems. The use of plenum fans in air handling units (AHU) as a replacement for belt driven double inlet fan solutions has drastically increased over the past years as they offer many benefits to manufacturers and end-users. Fan manufacturers recognized advantages of direct driven plenum fans a long time ago and focused their development efforts on high efficiency plenum fans. As such fans are always embedded and used in an AHU studies into built-in situations were carried out to obtain better knowledge and in order to support AHU manufacturers to consider installation effects when selecting the fan.
For air handling units, especially for high airflow or in retrofit projects, the use of multiple fans in an array is becoming very popular. The presentation includes benefits of a multi-fan system and points out where you should pay attention during the installation process. An important issue when building a multi-fan system is to consider mounting instructions. We investigated how performance and sound are affected if recommended minimum distances can’t be achieved. You obtain information about a smart solution to improve performance in such situations and to simplify the assembly process. One of the reasons for building a multi-fan system is to have redundancy and you will see what happens when one fan fails in terms of performance as well as a practical method of airflow measurement during operation.

Field Test & Site Commissioning
Mr PS Soong, P Eng, MIEM, MASHRAE, CPMP, GBICxS, Commissioning Specialist
GTG Industries
Abstract
High performance building can be a pride only with the occupants of building satisfied in
staying in the space. In the life cycle cost analysis of a typical office building,
construction cost is only a fraction to the overall expenditure including salaries of staff.
The ratio is applicable to all other types of buildings. Productivity & comfort of
occupants can only be enhanced with good indoor environmental quality in air
temperature, humidity, air movement and acceptable noise & vibration level. Design &
installation of air systems for high performance buildings is no longer limited to include
EE aspect but must include IEQ aspect as well. Design criteria for good IEQ includes
minimum ventilation, air change effectiveness, pollutant controls, mold preventions,
noise level reduction, controllability of air distribution devices, etc. Advance air system
such as UFAD (underfloor air distribution), VAV, radiant cooling system, etc. each need
the contribution of innovative products from manufactures. Acceptable noise & vibration
level can only be attained with designer & installer’s understanding on testing
parameters furnished by manufacturers and applying these data meaningfully in
equipment & accessories selection process. The speaker has verified IEQ parameters
of many high performance/green buildings during commissioning, often with
sophisticated instrument. He will share his experience with the audience on some of his
case studies.

Design Criteria: Attenuator & Acoustic Duct
Ir Nai Boonlert, Prakhun Acoustics
Abstract
The principals of Noise Control in areas of Mechanical and Vibration Noise Control will
be discussed and covered. Two types of noise, duct-borne noise and structure borne
noise will be taken into consideration, leading to the noise control mechanism used in
the ACMV system; such as plantroom wall insulation internal lining and the use of duct
silencer/attenuator. For duct silencers/attenuators, further explanations would be
provided in the mechanism and application for noise control with their related design
challenges. Various options and methods for choosing a good isolator and for
considering the transmissibility of the system will be discussed in relation to vibration
isolation issues. The eventual performance of a spring as an isolator will be discussed,
explaining as it is determined by the static deflection of the isolator combined with the
building slab deflection as a “whole” system.
