Which type of air conditioning system is commonly used for large buildings or entire city blocks and utilizes a central plant for cooling?
DSSSB - 2023,
Answer: B
A district cooling system is used for large buildings or entire city blocks, with a central plant for cooling. Chilled water from the central plant is piped to the buildings. Portable units, window units and split systems are for single rooms or small spaces and have their own compressors, so they do not use a central plant.
