Building environment design – design, dimensioning, installation and control of embedded radiant heating and cooling systems

The aim of this study is specifying the procedures and conditions of enabling the heat flow in water based on surface heating and cooling systems determined relative to system’s medium differential temperature. Determination of thermal performance of water based on the heating and cooling systems of the surface and their conformity to standards is conducted through the design document and a model. In this way, a uniform assessment and water calculation based on heating and cooling systems of surface will be possible.The surface temperature and the uniformity of the heated and cooled surface temperature, nominal heat flow density between water and space, the associated nominal medium differential temperature and the field of characteristic curves are given as the result.This research consists of a method based on finite difference or finite element and also simplified calculation methods based on pipes position and building structure type.This study is applicable to water based on embedded surface heating and cooling systems in residential, commercial, and industrial buildings. The methods can be utilized for the systems integrated into the wall, floor or ceiling without any open air gap. This method is not applicable for panel systems with open air gaps, not integrated into the building structure.The concluding results can be applied to the use of fluids other than water as a heating and cooling medium and cannot be utilized for testing of systems. These methods do not apply to heated or chilled ceiling panels or beams.
