This document specifies design criteria for closed water-based cooling systems in buildings and the design of such systems is described. The definitions are aimed at achieving an appropriate level of technical quality and maintaining the desired thermal indoor climate with minimum energy consumption.
This document does not apply to systems for dissipating process heat from industrial processes. It also does not apply to and does not amend product standards or product installation requirements.
This document is applicable to cooling systems of the following type (see also Figure 1):
1) devices for the water-based heat rejection of the chilling system;
2) devices for chilling and storage of chilled water;
3) devices for the distribution of chilled water;
4) devices for the absorption of heat ("cooling emission");
5) control devices;
6) safety devices
