Research About Application Technology Of Floor Heating

As a new heating of energy-efficient and comfortable, low-temperature heating system of floor radiation is increasingly applied to a wide range of housing construction. Domestic and foreign scientists and engineers carried on a large number of researches about its heating mechanisms, thermal comfort and energy-saving effect areas. But most research focused on the internal structure of the floors and heat transfer process, from the simulation calculation of heat transfer model established the internal floor, analyses cover thickness, and pipe distance, laying way and other factors for the system temperature distribution. As for the regulation and control of the floor heating radiation involved is less. Because radiation floor cover has capability of strong store heat and exothermic, the use of Thus, it need further study for cover floor heating systems intermittent operation to establish more realistic heat transfer model, summed up the law of temperature changes and provide a theoretical basis and practice guidance for designing,function and management..The major work done by the paper as the following:(1) This paper established heat transfer mathematical model for radiation heating room floor.(2) This paper establishes the two-dimensional physics and mathematics model of room air temperature and compute air temperature field of room with Fluent software, then analyze the results.(3) Analyses and compares several control strategies about radiant floor heating system (RFH).---- outdoor temperature reset control, flux-modulated control, on/off Control, intermittent fluid control , proportional-integral control, predictive control . This can be very helpful to the regulation of radiant floor heating system in fact.Academic calculation of this paper can supply academic reference and scientific gist for the designing and function. This paper has definite learned and applied importance.
