Investigation Of The Heat Transfer Mechanism In The PCM Heat-storage Floor And Thermal Performance Of The Room

For a long period in the north of China, during the winter ,people burn coal at most of time,but it lead to pollution of the air in th city.For this reason ,many cities use the natural gas, electric power to change environment .But if the electric power can be use with the heat-storage,maybe it is a good solution.In this paper ,we analyzed the heat transfer of the PCM heat-storage floor ,use numerical simulation,and study the PCM-material's specialist,the floor surface characteristic and the heating power.the result will provide suggestion in the project use.on the other side,we also study the room enviroment with cylindrical combustor.According the result of the typical and design situation of the room heating.It's honestly indicate the PCM heat-storage system can provide a good and warm environment.By the side ,it's save the power and balance the electric providing.From the result,it can provide a theory guide of the floor-heating system.
