Economic analysis on floor radiant heating/cooling systems

Presents the characteristics of the floor radiant system, compares the economic performance of different cooling/heating terminal devices, and puts forward a new evaluation index for the cooling/heating system—cooling/heating coefficient per exergy consumption ε。By comparing the floor radiant heating/cooling system to fan coil systems for cooling and radiator systems for heating respectively using the exergy analysis method, concludes that the ε of the floor radiant cooling system increases by 133% than that of the fan coil system, and the ε of the floor radiant heating system increases by 41% than that of the radiator system.
