| Abstract | Performance simulations of thermoelectric radiant panels (TERPs) provide valuable information for the use of TERPs as alternatives to conventional hydraulic radiant panels, which require refrigerants based on the vapor compression cycle. Several existing models are appropriate for the design of the TERP; however, there are limitations to the building simulation with respect to the evaluation of the annual energy performance because existing models for TERP are based on the numerical method, therefore it is very complex to integrate with the building model. To overcome these limitations, simplified empirical models should be developed based on experimental data and then verified.
This study aims to develop two simplified prediction models for the cooling capacity and energy consumption of TERPs. Using the 2k factorial experiment design method, a total of 16 experiment sets were designed according to the four main operation parameters: room temperature, outdoor air temperature, face velocity of air in duct, and combined heat transfer coefficient between room and panel surface. The developed models were designed in dimensionless forms to ensure broad applicability. The developed models yielded good R2 values exceeding 0.99 and were validated under additional operation conditions. Finally, the guidance of using the developed models and the performance tables of the TERPs was confirmed with respect to the use of TERPs in the construction of heating, ventilation, and air conditioning (HVAC) systems. |
