This standard 24/30479281 DC BS EN 17671 Heating systems and water-based cooling systems in buildings -Design for water-based cooling systems is classified in these ICS categories:
  • 91.140.30 Ventilation and air-conditioning 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 document 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. Figure 1 - Schematic example of a water-based cooling system The design of such systems is described in this document. Additional safety aspects for water-based cooling systems with local operating temperatures ≤ 0 °C are not covered by this document. The other clauses of this document are still valid for systems with local operating temperatures ≤ 0 °C. This document does not cover the chilling system itself, but only the parts of the chilling system which are an integral part of the cooling system, including determination of the design performance. Furthermore, this document does not cover: - the requirements for installation or instructions for operation, maintenance and use; - the design of the system components (e.g. recooler, chilling system, coolers, pipes, safety devices etc.).
