A building model with radiant cooling system was established and the cooling load,indoor temperature,surface temperature of the walls and other parameters in non-cooling and radiant cooling room were calculated by TRNSYS.The comparative analysis of the characteristics of attenuation and delay proves that the operation of radiant cooling system increases the degree of temperature attenuation of the room and reduces the inner surface temperature of the wall significantly,but has little effect on the attenuation coefficient and delay time of wall heat transfer.The simulation results also show that the inner surface temperature of the walls in the radiant cooling room is much lower than that in non-cooling room in the day with the maximum cooling load,which reduces the indoor operation temperature largely,and improves the thermal comfort.Finally,according to the analysis of indoor temperature of the rooms with different operation schedules of cooling system,it can be derived that the indoor mean temperature changes with the working time of radiant cooling system,and the operation schedule can be adjusted in practice according to the actual indoor temperature to achieve the integration of energy efficiency and thermal comfort.
