Analysis of indoor thermal environment and heat loss of radiant floor heating system

According to characteristics of thermal process in heating room, the dynamic thermal model of radiant floor heating room was set up, and numerically solved by finite volume method. For radiant floor heating room and radiator heating room, numerical calculation results indicated that under the condition of arriving the same thermal comfort as radiator heating room, the design indoor air temperature of radiant floor heating system can be reduced by 2-4°C, and that radiant floor heating system can save 10%-30% energy compared with radiator heating system.
