Numerical Simulation Analysis And Energy-saving Optimization Design Df Atrium Air Distribution
Using large-area glass roofs or glass curtain walls,atriums often have complex thermal environments.To this end,the computa-tional fluid dynamics method was used to compare the velocity field and temperature field simulation results of closed atriums with and with-out roof exhaust in air-conditioning mode,and the analysis concluded that:for summer conditions,the atrium can reduce the indoor de-sign cooling load by setting up roof exhaust,thereby saving air conditioning energy consumption;for winter conditions,whether the roof is equipped with exhaust ventilation will have little impact on the air flow organization of the atrium,the roof exhaust can be turned off to save energy consumption.
