scope:

This standard specifies requirements for heating and cooling systems. The requirements are intended to give a technical correct quality level, with the required thermal indoor climate maintained with the lowest possible energy consumption. The standard applies to all types of heating- and cooling systems, which have the purpose to supply rooms and buildings and connected systems with heating or cooling. The heating media respectively the cooling media in the system can be either e.g. water, air or electricity. The standard applies to heatling systems of the following type: - Central heating - Air heating - Electrical heating The standard applies to cooling systems of the following type: - Central cooling - Air cooling The standard requirements for heating- and cooling systems are valid for all types of supply systems e.g.: - Gas boilers - Oil boilers - Biomass boilers, e.g. wood, wooden pellets, straw and corn - Solar heating - Heat pumps - District heating - Geothermics - Electricity - Cooling machines - Groundwater cooling - Sea-, harbour- and sea water cooling - District cooling The standard does not apply to the supply system itself, but only the part of the supply system which naturally is part of the heating- og cooling system, including determination of the dimensioning performance. The standard does not apply to the individual e.g. : - Boiler - District heating main cock, including the service valve - Heat pump - Cooling machine - Electrical power supply The standard does not apply to ventilation and fire technical requirements. The standard does not apply to personal safety (for neither consumer nor operating personnel)
