【摘要】 本文以某典型住宅的户式中央空调为研究对象,研究户式中央空调系统的气流组织和热环境评价。采用CFD模拟技术,在试验验证的基础上研究不同类型户式中央空调及各种影响因素下,如送风温度、送风速度、风口位置等因素对室内流场及舒适性的影响;对不同空调方案及不同送风参数分别进行了模拟,得出了各种工况下的温度场和流场分布,并利用空气分布特性指标(ADPI)、不满意率(PPD)舒适度指标对居住环境进行了评价,为预测、分析、评价空调房间的气流分布提供了依据。模拟结果表明户式中央空调能创造良好的热环境,对户式中央空调系统设计与分析具有一定的参考价值。更多还原

【Abstract】 In this paper, airflow distribution and thermal environment assessment of household central air conditioning systems in a typical residential building are studied. Based on the results validated by an experiment, CFD methods are used to study air distribution and human thermal comfort influenced by different air conditioning system patterns and various air supplying parameters such as supply air temperature, supply velocity and places of grilles. Temperature and velocity distribution of different air conditioning systems and various air supplying parameters are obtained by numerical results. Thermal indexes of APDI and PPD are applied to evaluate thermal environment of residential buildings. Conclusion obtained by simulation results can predict, analyze and evaluate airflow distribution of air condioning. Simulation results indicate that Household central air condioning systems can create good thermal environment for occupants and the results are beneficial for designing household central air conditioning systems.更多还原
