Heating systems and water based cooling systems in buildings - Design for water based cooling systems

This document specifies design criteria for closed water-based cooling systems in  buildings. The requirements aim at achieving a proper technical quality level and  maintaining the desired thermal indoor climate with minimum energy  consumption.Systems for dissipating process heat from industrial processes, for example,  are not covered by this document.This document does not amend product standards or product installation requirements. The standard covers cooling systems of the following type (see 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.
