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.

INTRODUCTION

District Cooling had been introduced and installed in Malaysia for the last 20 years and is being promoted as a way of addressing energy efficiency, energy demand and global warming. The shift in the electricity demand and supply balance, has paved the way for deployment of District Cooling incorporating Thermal Energy Storage which allows the Utilities & Developers to balance the power demand and effectively manage usage.

This course will bring to the understanding of the participants regarding the various aspects of District Cooling Plant design and implementation. Some of the key issues in the design and operation that can affect the efficiencies and viability of the District Cooling Plant will also be discussed.

The participants will have the opportunities to understand the various types of Thermal Energy Storage Systems and compare the merits and demerits of each system. He/she can also learn how to calculate, size up and optimize the Thermal Energy Storage system.
