Computer Simulation Analysis on Energy Saving of Low-temperature Floor Radiant Heating System

A heating system simulation program based on space thermal network is introduced, and computer simulations of two different heating systems, including lowtemperature floor radiant heating system and convective heating system, are carried out with this program. Dynamic analysis of the heating load,inside temperature and interior surface temperatures under two different heating systems in a day are presented. The lowtemperature floor radiant heating system is proved to be energyefficient in comparison with the convective heating system.
