Assignment task:
When comparing chilled-water systems to DX systems in terms of refrigeration capacity and other characteristics, which of the following statements is true (Section 6.4)? a. Chilled-water systems are generally louder and more visually prominent compared to DX systems, and they have a higher diversity factor in industrial applications, usually exceeding 90%. b. Chilled-water systems are generally less expensive than DX systems and can only serve individual air-conditioning units. c. Chilled-water systems can be quieter and less visible than DX systems, with the noisiest and most visually objectionable components confined to isolated spaces away from occupied areas, and they can be sized for net demand load, potentially offering substantial equipment savings. d. Chilled-water systems can serve multiple individual air-conditioning units and are generally sized for the accumulated peak design loads, resulting in higher costs compared to DX system
