ABSTRACT
Seemingly small efficiency improvements to traditionally designed chiller plants multiply to create impressive savings in district cooling plants. The size and scope of these larger projects make the benefits more obvious and very valuable. For example, the United Arab Emirates is fully embracing district cooling for accommodating its tremendous growth, rather than using individual cooling systems in each building. It has been estimated that 75% of the energy used in Dubai, U.A.E. is for cooling. By using district cooling, Dubai planners expect to reduce the amount of electrical energy used by 40%. More than 30% of the Dubai market is selecting pre-engineered, packaged chilled water systems, many of which employ series chillers, variable-primary distribution design, and other concepts discussed in this entry.
