摘要
运用零方程模型对某店面的气流组织和舒适性进行数值模拟,利用有限容积法和SIMPLE算法对微分方程进行离散求解,研究了室内空气温度云图、PMV云图和PPD云图分布规律。模拟结果表明:在夏季该店面的空调系统在3种不同情况下均能满足健康、舒适和节能等方面的要求。CFD技术可预测室内气流组织、热舒适性及为空调系统优化设计方案提供理论依据和科学指导。
Air flow organization and thermal comfort of an air conditioning shop were numerically simulated with zeroequaltion model provided. The finite volume method and SIMPLE arithmetic were adopted to disperse and solve the differential equation. Temperature nephogram, PMV nephogram and PPD nephogram was studied in this paper. Simulation results indicated that the air conditioning system of the store in summer was health, comfortable and energy saving etc in three different cases. CFD technology provides theoretical basis and scientific guidance for predicting indoor air flow organization, thermal comfort and optimizing design scheme of air conditioning.
