The possibilities and limitations of using radiant wall cooling in new and retrofitted existing buildings

Original language description

The use of radiant wall cooling presents a potentially feasible solution to cover the cooling demand of buildings due to its suitability for combination with renewable energy sources at relatively high sensible cooling capacity. We define and directly compare four types of wall cooling systems, from which three are potentially suitable for building retrofit. Besides using established performance indicators, an indicator called heat transfer efficiency is introduced to allow detecting differences in the thermal dynamics of various systems even in cases when their response time, defined as τ95, is alike. Systems with pipes underneath the surface provide higher cooling output and are sensitive to pipe spacing. Systems with pipes embedded in the core allow thermal storage and are sensitive to insulation thickness. Thermal conductivity of the core material proved to be an important parameter to consider except for the system with the pipes separated from the core by thermal insulation. The systeḿs suitability depends on the requirements such as avoiding interventions in the interior, exploiting thermal storage, or providing fast thermal dynamics. It is shown how various configurations of pipe location, material layers and thermal conductivity of the core allow compromising between the different performance indicators to design a system with the desired characteristics.
