Course Overview

This course introduces you to the fundamental engineering concepts and applications in chiller and cooling tower operations. The first part of the course covers the concept of Air Conditioning and Mechanical Ventilation (ACMV) in buildings. Various types of building cooling systems, building cooling load and efficiency calculation, as well as the use of Building Management System (BMS) for water-side and air-side controls will be explored. The second part of the course introduces the auxiliary equipment of chiller systems, namely the cooling tower, its operating mechanism, and the water and energy balance in the tower. Basic water chemistry, including water quality monitoring and treatment, corrosion control, as well as regulatory requirements for water, will also be discussed.
