The Process Sensitiveness Analysis of Radiation Heating (From Floor) In Building

In this article, the effect of various parameters has been studied on heat time of a room through floor heating. By time solution on heat transfer equations, with consideration conduction, convection and radiation mechanisms in three point: room floor, middle of room height and room ceiling and modeling of finite element have been used. This heat transfer problem has been solved by ANSYS code. In this model, heat from water pipe transfer to area by conduction mechanism and heat transfer from floor with convection and radiation mechanism to room air cause to grow hot the room that grow hot behavior have been studied in three point at long of time. The parameters that studied arc: change effect of diameter, type, number of heat transfer pipe in floor, thickness effect and type of various covering that heat transfer perform by convection and radiation.
