In Korea, the radiant floor heating system has been widely used as a residential heating method, which has been modernized to use hot water running into the tubes embedded in the floor structure.According to the recent improvement of living stand ard in residential buildings, the requirement of the thermal comfort and energy saving in heating system has been raised.Until now, the radiant floor heating system has been controlled by one room thermostat installed in the main living room, but for better thermal comfort, an individual room control method is adopted as an alternative.Therefore, it is necessary to evaluate the control performance between the current control method and the individual room control method.In this study, the control performance between the two control methods is firstly evaluated through the field test.And the control performances of room air temperature and energy are analyzed through the simulation using the TRNSYS.For this, the simulations are performed in the various outdoor conditions and valve on/off status and the simulation results are analyzed for the control performances.Also, to evaluate the energy performance, the simulations are performed under the operating conditions in which the set-point of the room air temperature is fixed or changed according to the occupancy schedule, and the simulation results are analyzed between the two methods.
