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

Cooling capacity calculation is the most fundamental requirement for any air conditioning system design. The application of psychrometric principles is often regarded as an area of mystery to many air conditioning engineers. However, it is the key for solving many air conditioning problems such as condensations, humidity problems, non-performance at part-load operations etc

 

OBJECTIVES

The objective of this course is to enable participants to calculate the cooling capacity required for a particular air conditioning system.  Furthermore, the participants will understand the practical applications of psychrometric in air conditioning, design for humidity controlled systems and problem solving using psychrometric chart.

 

TOPICS

 HEAT LOAD CALCULATION

  • An overview: heat loads and cooling capacities, temperature as a state of equilibrium
  • Methods of cooling load estimation
  • Heat load calculation using E20 method
  • Some short-cut methods

 FUNDAMENTAL PSYCHROMETRICS

  • A study of the properties of the moist air
  • Dry bulb and wet bulb temperatures
  • Humidity: Relative humidity and moisture contents
  • Dew point temperature
