Research About Application Technology Of The System Of Gas-fired Radiant Heating

For a long time, the heating of tall space building is a big problem which puzzles heating ventilation engineer, but the gas-fired radiant heating has resolved this problem well, and it is the best choice for tall space building's heating because of its excellences for e. .xample saving energy comfortable and clean. The research of gas-fired radiant heating in our country starts late, the cognition for running practice and technic characteristic which is the system of gas-fired radiant heating is half-baked, design and construct are empty of experience. Therefor this paper has researched the system of gas-fired radiant heating. The main job is as follows:(1)The composing ,class, excellence and saving energy- environment for the system of gas-fired radiant heating has been introduced particularly;(2)Base on the heating transfer, the process of heat transfer in gas-fired radiant heating has been analyzed roundly;(3)The three-dimensional physics and mathematics model has been established, confirmed the boundary condition ,gained the whole mathematics description and control equation. The mathematics model is dispersed by finite elements method. Simulated calculated space temperature field by using Fluent,and analyzed air temperature grads in the room, radiation temperature grads;(4)Otherwise, the paper combines theory with practice, introduces the project choice, the design method, the design approach and the notice detailedly of gas-fired radiant heating. The research offers an essential theory gist and a practice guidance in the future design and construction working.
