To improve simulation accuracy and to ensure the authenticity of the simulation results, the difference scheme of control equation adopt second-order upwind scheme, and the pressure-velocity coupling method of flow use SIMPLE algorithm [9,10,11]. 2 Analysis of simulation results Figure 2 is the room temperature distribution cloud map in N-N section.
Contrasted with Figure 2 and reference [12], the temperature distribution is similar, so the results of this simulation accurately reflected the indoor air distribution.
The heat transfer on maintenance structure has little effect on temperature field and air distribution, so the simulation ignores the heat transfer on maintenance structure.
The simplifying and assumption make the simulation results had some difference to the actual situation, but the effect is little.
