PROFILE OF COURSE FACILITATOR

Ir. Chua Keng Seng, B.E.(Hons), MIEM, P.Eng., MASHRAE, MIMM, CCP, graduated from the University of Malaya in 1974. Qualified as a Professional Engineer, he worked with Carrier Malaysia Sdn. Bhd., first as the Service Manager and then as Engineering Manager for about 10 years. During the next 25 years, he operated his own companies in contracting, maintenance and also in consultancy business. He has wide experience in the design, installation, trouble shooting on various types of systems and also in project management. He was in the design and project management team which implemented the Putrajaya Precinct 2 District Cooling Plant which has a capacity of 30,000 cooling tons.

Ir. Chua has also been involved in many training programmes. He lectured air conditioning design in the Mechanical Faculty of University Malaya between 1978 to 1984 and in Monash University for the last 3 years. Besides he had been invited to deliver lectures and presentations in the University Technology Malaysia, University Technology Petronas, The Institution of Engineers, Malaysia and conducted in-house training for some Corporate Companies.

TOPICS

Introduction

Can the Chiller Plant be operated independently to achieve the desired high efficiency?
Understanding the inter-relationship between the Chiller Plant, Chilled Water Distribution System and the Air-side System from the formula : Q = K x F x dT.
What are the implications on the performance of the entire Air Conditioning System with the new trend of improving the Chiller Plant efficiencies by increasing the Supply Chilled Water Temperature and increasing the delta T of the chilled water system?
What are the common causes for moulds and fungi to grow on surfaces in an air conditioned space?

Understanding the performance of chilled water cooling coil

Fundamental understanding about the air flow capacity and cooling capacity of the coil
Increasing Chiller Plant efficiencies using high Chilled Water Supply Temperatures and high Delta T can affect the performance of the AHU and Indoor Air Quality
How the non-performance of cooling coil relating to low delta-T affects system efficiency
The low delta T problems with the Cooling Coil: design, selection, operation and control aspects

How the Water-side performance of Air Handling Units affect the energy efficiency of the entire system

Constant flow and variable flow in chilled water system design
Modulating control valve issues: selection and sizing
Modulating control valve issues: operation and control
Pressure Independent Control Valve and Energy Control Valve

How the Air-side performance of Air Handling Units affect the energy efficiency of the entire system

The miss-match between Chiller Plant and AHU optimization: supply water temperature, delta-T and cfm/ton
How Constant Air Flow and Variable Air Flow designs affect energy efficiency and energy wastage.
How the choice of Supply Air Temperature affects chiller plant performance, first cost and operating cost of air-side system and the indoor environmental quality performance.

How Dedicated Outdoor-air System (DOAS) design improves energy efficiency and system performance in humid climate

Why use DOAS: Demand Control Ventilation
Why use DOAS: separating the roles of sensible cooling and latent cooling
DOAS allows higher Supply Chilled Water Temperatures and higher Delta T to be used for better chiller plant efficiency.

Under-floor Air Distribution System design and performance

The advantages of Under-floor Air distribution System
How to design with higher Supply Air Temperature without increasing the humidity level in the room space.

The advantages of using Chilled Beam and Chilled Ceiling systems
How to prevent condensation problems in humid climate
What are the limitations when using Chilled Ceiling System in Malaysian climate.

Designing Chilled Water Distribution System for system efficiency

The fundamental concepts of constant flow and variable flow in Chilled Water Distribution System
Constant flow system; variable flow to air-side with by-pass in chiller plant room
Constant Primary and Variable Secondary flow system
Variable Primary and Variable Secondary flow system

Energy saving design with Distributed Secondary Pumping System

Understanding the fundamental pumping energy equation
Under what circumstances Distributed Secondary Pumping system can save energy
Variable Primary Pumping with Distributed Secondary Pumping Systems

Energy saving design with Tertiary Pumping System

Under what situations Tertiary Pumping Systems can save energy
Comparing Tertiary Pumping and Series Pumping

Efficient Chiller Plant Control System

Fundamental concepts about flow control and capacity control
Control philosophies for Secondary Pumping and Primary Pumping systems
Chiller Capacity Control, Chiller Staging Control and Chiller Minimum Flow Protection
