Radiant ceiling systems coupled to its environment part 2: Dynamic modeling and validation

Radiant ceiling systems coupled to its environment part 1: Experimental analysis

“…This is due to the increase of the thermal contact resistance for capillary tubes mats considering the additional air layer between the tubes and the ceiling metal panel. In general, all these results are considered during the modeling approach [12], presented in a further study. Test TGH1 TGH2 TGH3 TGH4 TGH5 TGH6 TGH7 TGH8 TGC1 TGC2 Test TGH1 TGH2 TGH3 TGH4 TGH5 TGH6 TGH7 TGH8 TGC1 TGC2 …”

“…This article summarizes an experimental investigation and analysis of two radiant ceiling systems with three different configurations. In a second part of this study a dynamic model of radiant ceiling panels in heating or cooling modes coupled to its environment is presented (fenestration, walls, internal loads and ventilation system) [12].…”

A dynamic simplified model of radiant ceiling cooling integrated with underfloor ventilation system

“…Referring to the simplification of heat transfer model for pipeembedded structure [22][23][24][25][26][27][28][29], water is regarded as a cooled source, and R 2 is considered since there is direct heat conduction through pipe layer. The sum of R 3 and R 4 in series is connected with R 2 in parallel.…”

“…Therefore, Koschenz and Lehmann [22], Weber and Jóhan-nesson [23], Gwerder and Lehman [24] and Liu et al [25] developed a dynamic simplified RC-network model for pipe-embedded structure. Recently, Fonseca et al [26,27] proposed a dynamic RC-network model of radiant ceiling panels coupled to its environment. And Su et al [28] presented a two dimensional steady-state heat transfer model of concrete ceiling radiant cooling panel by using FDM.…”

“…There have been considerable amount of research on heat transfer model of radiant cooling system and pipe-embedded building envelope [18][19][20][21][22][23][24][25][26][27][28]. Antonopoulos [18] developed a steady-state model for wall temperature field analysis.…”
