| dc.description.abstract | The issues of indoor environment quality are a significant challenge to relative organizations for the policies of environment sanitation and national health in city type society. Furthermore, it is extremely urgent that information establishment on fundamental behavior and flow field of air conditioner system and heat flux function for building space in our country. Because, it is in order to be founded effective improvement tactic or control plan for indoor environment quality. Seeing that, the CFD FLUENT program based on numerical analysis and combining with Gambit pre-processing tool are applied to a series of simulation, comparability, and analysis for air conditioner and heat flux of indoor space flow field in this research.
Investigation results showed that: (1)It is confirmed that CFD FLUENT program has the powerful operation and timely analysis ability in modeling establishment, set up of material and boundary parameter, iterative calculation, analytic data, post-processing graph, and animated display etc. (2)Small-pipe model has more lower and uniform than general-pipe in velocity field and turbulent intensity field, and for this reason, it can be reduced the draft rate. (3)Temperature field is controlled main to air con type of air return way, pipe size of inlet and outlet etc. (4) The relationship between the Draft Rate and the flow fields, the speed field is the highest relation, the turbulence intensity field is the middle relation ,and temperature field is the lowest relation. (5)T he number of small diameter pipes of the flow field have linear trend for the average value.ditioner system in indoor space, and it is lower correlation with arrangement
