The purpose of this study is to investigate an exergy analysis on embedded pipes of radiant ceiling cooling system. Based on the thermodynamic principles, the exergy analysis model of radiant ceiling cooling system is established. The exergy efficiency of radiant ceiling cooling system and its main equipments can be simulated and calculated by the model. Under the different pipe spacing, depth and diameter, the exergy efficiency of radiant ceiling, refrigerating unit, pump and radiant ceiling cooling system and the surface temperature of radiant ceiling panel are compared and analyzed and the exergy loss coefficients of radiant ceiling panel, refrigerating unit and pump are calculated. The conclusions show that pipe depth and spacing have primary influence on exergy efficiency and surface temperature distribution respectively and the refrigerating unit is the most important part for exergy saving in radiant ceiling cooling system.
Key words: Exergy analysis, exergy efficiency, radiant ceiling cooling system, simulating calculation , , ,
