SYNOPSIS:

Since the invention of air conditioning, it has resulted in tremendous changes in humans' way of life. Aside from elevating the comfort levels of living spaces and work environments, air conditioning also led to increases in work productivity and helped humans adapt to harsh environments, even surviving outer space.

However, all these benefits come with a price: the huge amounts of energy required to keep the air conditioning systems operational.
In tropical regions, the air conditioning system in a standard commercial building will consume up to 60% of the building's total electrical energy consumption. With more and more skyscrapers being built in the cities, chillers of increasing numbers and larger sizes will eventually be installed to keep these buildings habitable. In order for such a fast growing city to have continuous and sustainable development, air conditioning engineers face the challenge of designing highly energy efficient chilled water plants - capable of providing the most comfortable conditions while using the least amount of energy possible in a building.

The key to designing an energy efficient chilled water plant is not about reducing the electricity consumed by running lesser numbers of chillers or raising the space set temperature to a higher point, which will eventually compromise the comfort levels. Instead, careful considerations need to be invested during the design stage, to get things right the first time, and to have achieve a robust yet comprehensive control system to ensure more efficient management. The primary objective in maximizing the performance of a chilled water plant is to minimize wastage by operating the equipment in the most optimum way and following the load profile closely. Furthermore, clear understanding of the design concerns, limitations of the equipment, as well as the building's dynamic load is crucial to deliver an energy efficient chilled water plant.

Lastly, as the final puzzle piece, a carefully designed control system fitted with sufficient numbers of measuring instruments and high accuracy sensors will be required. With the technological advancements in sensors and ever improving computing powers, a chilled water plant can be operated in a more refined way, to achieve energy savings and at the same time without compromising the comfort levels.
