[en] This paper presents the results of an experimental analysis of the radiant ceiling systems in both heating and cooling modes coupled to its environment (fenestration, walls, internal loads and ventilation system). The main objective of this study is to present the results of the systems performance and measurement methods used to evaluate the influence of some important parameters on the radiant ceiling capacity and comfort conditions.
Two test chambers are adapted in a way to reproduce as good as possible the characteristics of the real offices located in Brussels. Forty-six tests were performed in which the main objective was to observe the influence of parameters such as the mass flow rate, supply water temperature and thermal load distribution, fenestration and ventilation system effects. Laboratory test results show that the influence of surfaces temperatures inside the room, especially the facade, is considerable. Therefore, the system must be evaluated together with its designed environment and not as separate HVAC equipment.
