In order to solve the local overheating and the energy waste of radiant floor heating systems in railway stations on the plateau with intensive solar radiation,a railway station on the plateau was studied,and a partition heating scheme of the radiant floor system was proposed according to the solar radiation distribution in the station.The building energy consumption simulation software,namely Energyplus was used to simulate the station,and both the indoor thermal environment and the heating capacity of the radiant floor system with or without the partition scheme were compared.Results show that when the radiant floor system adopts a unified design and operation control scheme for heating,the average operative temperature in the irradiated zone can reach up to 27℃ during the daytime,and the temperature difference with the unirradiated zone is more than 5℃.When the radiant floor system uses the partition heating scheme,the maximum operative temperature in the irradiated zone is 26℃.The indoor temperature distribution is more uniform,and the local overheating is alleviated.Under the premise of ensuring the thermal comfort of the station,the partition heating scheme of the radiant floor system can reduce the heating capacity in the irradiated zone during the heating season by 38.2%.
