The climatic test chamber is a classroom/conference room which takes piace on thè second floor in building 402, Department of Civil Engineer at Technical University of Denmark. This room is equipped with different types of heating, ventilation, and air-conditioning systems (HVAC). The purpose of HVAC System is to provide good air quality and comfortable thermal environment that will ensure occupant's satisfaction, health and high productivity.

The objective of the thesis is to investigate through experimental analyses the indoor environmental parameters and the energy performance inside a classroom combined ventilation System (Displacement Ventilation) with radiant panels (Chilled ceiling/floor). The development of thè radiant panels is growing as a low-energy systems, and represent a technology with broad potential application of low energy requirements. In addition to the energy, the thermal comfort guarantee enhancement of the System: in fact they are mainly based on radiation heat exchange. In particular, the research work's aim is to provide an optimal thermal comfort and a good IAQ during the summer period, when the heat loads in the classroom is quite high.
