Wet":in addition to hot summer and cold winter,another factor causing our country region of hot summer and cold winter climate condition is not livable is high humidity in summer and winter.Due to water network is densely,numerous lakes in the middle and lower reaches Yangtze,air humidity is maintained all the year round in 80% or so.Due to high temperature and humidity in summer,it’s hard for human sweat to volatilize and discharge,causing more sultry sense.Wet vapor from the human body absorb heat in winter,together with the relatively a litter seasonal sunlight,making human feel more cold and damp.
The simulation using the Fluent software,Fluent software is a kind of CFD commercial software, used to simulate complex flow from incompressibility to a highly compressibility.Due to the adoption of several solution methods and multi-grid acceleration convergence,Fluent can obtain the optimal convergence speed and precision.Fluent Air-pak is geared to engineers,architects and designers professional artificial environment system analysis software, especially HVAC domain,can simulate the internal air flow of object,heat transfer and pollution physical phenomenon precisely,can simulate the ventilation system air flow,air quality,heat transfer,pollution,comfort degree and other problems accurately,and provide comfort,PMV,PPD measure of indoor air quality ( IAQ ) technical indicators in accordance with ISO 7730 standards.
