This part of ISO 11855 specifies procedures and conditions to enable the heat flow in water based and electrical surface heating and cooling systems to be determined relative to the medium differential temperature for systems. The determination of thermal performance of water based surface heating and cooling systems and their conformity to this part of ISO 11855 is carried out by calculation in accordance with design documents and a model. This should enable a uniform assessment and calculation of water based surface heating and cooling systems.

The surface temperature and the temperature uniformity of the heated/cooled surface, nominal heat flow density between water or electrical heated layer and space, the associated nominal medium differential temperature, and the field of characteristic curves for the relationship between heat flow density and the determining variables are given as the result.

The ISO 11855 series is applicable to water based embedded surface heating and cooling systems in residential, commercial and industrial buildings1). The methods apply to systems integrated into the wall, floor or ceiling construction without any open air gaps. It does not apply to ceiling mounted panel systems with open air gaps which are not integrated into the building structure.

The ISO 11855 series also applies, as appropriate, to the use of fluids other than water as a heating or cooling medium. The ISO 11855 series is not applicable for testing of systems. The methods do not apply to heated or chilled ceiling panels or beams.

This part 6 of ISO 18566 establishes guidelines for the determination of input parameters for ceiling mounted radiant heating and cooling panels for the ISO 52031. The requirements specified by this part 6 of ISO 18566 are applicable only to the components of the heating/cooling systems and the elements which are part of the heating/cooling panels and which are installed to provide heating and/or cooling.

The ISO 18566- series is applicable to water based ceiling mounted radiant heating and cooling panels in residential, commercial and industrial buildings. The methods apply to systems mounted under the ceiling with an open air gap between the panels and the ceiling.

The ISO 18566- series also applies, as appropriate, to the use of fluids other than water as a heating or cooling medium. The ISO 18566- series is also applicable for testing of systems. The methods do not apply to heated or chilled ceiling beams.
