Along with national economy development and lives of the people level enhancement, in people's more and more is also high to room heat comfortable level request, but at the same time, actually is following the energy suddenly consumption. Therefore, how namely can meet people's need, also enables the source the consumption to be lowest, warmly passes the research topic which engineer always craves.But uses outdoor natural environment directly the superiority, reduces the energy the consumption, also is a research principal aspect. Looks like our country Kunming such area, because it in the climatic conditions superiority, may use outdoor air to take the heat sink directly, applies in the air conditioning aspect. But a waiting plane's hall is that personnel are many, flowing high frequency public place, its room internal heat comfortable level, also should receive people's attention. Therefore, this topic encompassment uses outdoor air to a waiting plane's hall directly application as the heat sink in Kunming, carries on launches the analysis and the research.First, carries on the analysis to the Kunming area climatic conditions, summarizes directly uses outdoor air takes the heat sink the feasibility.Next, to simplify the waiting plane's hall in Kunming physical model, under the unified blast parameter and the boundary condition, to adopts 3 kind of different air current organizations the blast and the vent way, conducts the numberical simulator study. Use commercial software Airpak, used indoor zero equation model to carry on the numberical simulation analysis, the analysis studies indoor temperature field, the velocity field, Predicted Mean Vote (PMV), Predicted Percentage of Dissatisfied (PPD) and the mean age of air, the analogue result believed that, air current organization way that two-sided openings are top and the two-sided vent are bottom to the waiting plane's hall in Kunming analog modeling effect to be best.Finally, in uses air current organization way that two-sided openings are top and the two-sided vent are bottom to the waiting plane's hall in Kunming analog modeling foundation, according to the climatic conditions analysis result, selects 3 kind of typical outdoor air parameter in the waiting plane's hall in Kunming, with the numberical simulation method, the analysis studied indoor temperature field, the velocity field, PMV, PPD, then obtained uses outdoor air parameter directly to the waiting plane's hall application feasibility as the heat sink in Kunming.
