| Air distribution in large space atrium air conditioning is that many scholars have always been the purpose of the study,mainly because of the unique nature generally has the structure,space,and thermal characteristics is special for the atrium,and is large energy consumption of air conditioning system and comfort treatment difficulties.How to choose the appropriate scheme will need to bring various schemes for the effect and effect can be predicted,the air distribution is simulated by the calculation model of computational fluid dynamics,and the simulation of the air conditioning effect of different design schemes,due to the development of the computing ability of computer,already can be done through the computer simulation mathematical calculation.In this paper,numerical simulation(CFD)is applied to analyze and study the multi scheme of atrium air conditioning system in tall buildings,in the hope of providing some help for the design of practical projects in the future.This paper takes the tall atrium of a building in Beijing as the object of study.According to the actual size and various parameters,the calculation model of the stratified air conditioner in the large atrium is established.The software CFD uses is ANSYS's Airpark numerical simulation software,and modeling and analysis of the atrium under the software.Numerical simulation and analysis are made on the arrangement of the various schemes under the layered air conditioning scheme.Through the air conditioning system in the actual installation after do field test,the actual data obtained by many front-line careful testing,and according to the simulation result and the final actual measured are compared and analyzed.The correctness and reliability of the simulation method are verified.In this paper,numerical simulation is applied to the design of air conditioning in large space atrium,and the research basis for energy saving of air conditioning system in large space is also provided. |
