Heating, Ventilation and Air-Conditioning (HVAC)
About This Course
Buildings, including industrial and commercial buildings, consume 45% of total electricity generation from the main grid or other local generations, leading to global warming and a significant high carbon dioxide (CO2) emission to the environment. Almost 50% of building energy consumption is attributed to air conditioning systems. In tropical regions like Singapore, space cooling is essential for industrial or commercial buildings throughout the year to improve productivity, comfort level and indoor air quality. As chiller plants are an essential part of the buildings and consume a significant amount of energy, this module focuses on the fundamental of chiller plants and their associated components such as blowers, fans, piping networks and ducting networks. The operation of a chiller plant is also paramount to optimising the energy consumption required for cooling. Thus, the selection of a chiller plays a considerable role in such energy-efficient operation of the plant.
This module focuses on the chiller plants and includes the following sub-topics:
1. Fundamental of Chiller plants and their associated components.
2. Selection of chillers
3. Waterside circulation system
4. Fundamentals of Cooling towers and their operation
5. Chiller selection and chiller plant design consideration.
6. Minimising the energy consumption of the chiller plant.
