It is also important to take into consideration of the humid hot climate that we have in Malaysia to ensure that the design is workable here. It is also the objective of the course to equip engineers with the in-depth understanding of the various aspects of HVAC system design. COURSE CONTENTS Understanding the fundamental theories of refrigeration systems performance The Refrigeration Cycle: cooling capacity, power input and efficiency Sub-cooling, superheating and the compression index How the operating conditions affects performance of the refrigeration system Understanding the fundamental psychometrics In-depth understanding about dry-bulb, wet-bulb and dew point temperatures Moisture contents and Relative Humidity : the mould growing issues How to control RH% in an air conditioned space Sensible Heat and Latent Heat capacities Understanding the features of different types of Chillers Positive Displacement and Dynamic Compressors Reciprocating, Scroll and Screw Chillers: features & part-load control Understanding the Compressor Envelop Centrifugal Chillers: feature, capacity control, surging, compressor map

2 4.0.0 Variable speed drive control on various types of Chillers Capacity control using VSD for reciprocating, scroll and screw chillers Capacity control using VSD for Centrifugal Chillers Limitation of VSD control in Centrifugal Chillers when used in Malaysian climate conditions Parameters affecting the performance of chillers The effect of condenser water temperatures on chiller performance The effect of chilled water temperatures on chiller performance The effect of fouling factors on chiller performance Specification of the Delta T and the System Performance Specification of Cooling Tower Water Temperature at full load and part-load Understanding the working principles of cooling towers The effect of Wet-bulb temperatures on Cooling Tower performance The performance of cooling tower during the nights under Malaysian climate conditions The performance of cooling tower under part-load conditions Full load and part load efficiencies of Chillers Full load and part-load efficiency ratings for chillers Understanding Certification Ratings and Performance Ratings Elements which can affect the actual performance of chillers during operation Design ambient Dry Bulb and Wet Bulb Temperatures Design temperatures based on percentile frequencies of occurrence In-depth understanding on Wet-bulb Temperature and its effects on cooling tower and fan coil unit ratings

3 9.0.0 Variable Chilled Water Flow and Variable Condenser Water Flow systems The benefits of variable chilled water flow Some limitations in the implementation of variable chilled water flow system Some pit-falls to avoid during the design and operation of variable chilled water flow system The benefits of variable condenser water flow design Some limitations in the implementation of variable condenser water flow system in Malaysian climate Series Counterflow connection for Chillers The advantages of Series Counterflow Chiller Plant design The limitations of Series Counterflow Chiller Plant design Specifications of AHU and its Performance Understanding the cooling capacity and air flow capacity of the AHUs The performance characteristics of the Cooling Coil at various chilled water flow-rates The psychometric calculations for the air flow quantity, on-coil and off-coil temperatures of the AHUs The significance of cfm/ton for the AHU The performance of AHU at part-loads The consequences of over specifying the AHU capacity Specifying chilled water control on AHU Constant flow and variable flow controls Selection and sizing of Control Valves Low Delta-T syndrome The use of Pressure Independent Control Valves and Energy Valves Pump performance and Chilled Water Distribution design Understanding the performance of Centrifugal Pumps Variable speed control on water pumps Different design of chilled water distribution systems Variable Primary Flow design

4 PROFILE OF COURSE LEADER Ir. Chua Keng Seng, B.E.(Hons), MIEM, P.Eng., MASHRAE, MIMM, CCP, graduated from the University of Malaya in 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 inhouse training for some Corporate Companies.
