ASHRAE District Cooling Guide
The purpose of ASHRAE District Cooling Guide is to provide guidance for all major aspects of district cooling system (DCS) design. The guidance is organized to be of use to both the inexperienced designer ofDCSs as well as to provide a comprehensive reference to those immersed in the district cooling industry. In addition to design guidance, information on operations and maintenance have also been included.
District cooling (DC) normally distributes thermal energy in the form of chilled water from a central source to residential, commercial, institutional, and/or industrial consumers for use in space cooling and dehumidification. Thus, cooling effect comes from a distribution medium rather than being generated on site at each facility.

Whether the system is a public utility or user owned, such as a multi-building campus, it has economic and environmental benefits depending largely on the particular application. Political feasibility considered, particularly if a municipality or governmental body is considering a DC installation. Historically, successful DCSs have had the political backing and support of the community.

DCSs consist of three primary components: the central plant(s), the distribution network,
and the consumer systems or customer’s interconnection (i.e., energy transfer station
or ETS); see Figure 1.1. In the central plant (see Chapter 3) chilled water produced by one or more of the following methods:
- Absorption refrigeration machines
- Electric-driven compression equipment (reciprocating, rotary screw, or centrifugal chillers)
- Gas/steam turbine or engine-driven compression equipment
- Combination of mechanically driven systems and thermal energy driven absorption systems
