Chillers are predominantly utilized in larger buildings due to their requirement for chiller plants, which significantly increases installation and operational costs. In contrast, Direct Expansion (DX) units are favored for smaller spaces because they are more cost-effective and simpler to install. Although manufacturers produce smaller chillers under 10 tons, the overall expense of establishing a chilled water plant makes them less viable for smaller buildings. The discussion highlights the economic factors influencing the choice between chillers and DX systems.
