摘　　要：高大空间空气温度分布梯度较大,不同的送风方式对室内舒适度及节能效果影响较大。文章针对一种用于高大空间的新型风机盘管空调系统开展研究,从室内热舒适的角度与传统的喷口送风对比,以重庆某大学综合楼的备用展厅为研究对象,利用数值模拟的手段对比分析了两种送风方式的温度场、空气龄以及PMV-PPD值。结果表明:相同出口风速下,新型风机盘管的气流组织明显优于传统喷口送风;室内在达到相同热环境时,新型风机盘管的经济性优于传统喷口;新型风机盘管风口风速设计的过高,会在风口垂直向下的区域内产生一块热舒适性较差的低温区。The gradient of air temperature distribution in large space varies significantly,and different air supply modes have a great impact on indoor comfort and energy saving effect.This paper studies a new fan coil air conditioning system used in large space.Besides,based on the separate study of the new fan coil air conditioning system from the perspective of indoor thermal comfort,this paper introduces the traditional nozzle air supply to compare it,and compares and analyzes the temperature field,air age and PMV-PPD value of the two air supply methods by means of numerical simulation in a spare exhibition hall of a comprehensive building of a university in Chongqing.The results show that under the same air outlet velocity,the air distribution of the new fan coil is obviously better than that of the traditional nozzle air supply;when the indoor air reaches the same thermal environment,the economy of the traditional nozzle air supply is not as good as that of the new fan coil;if the air outlet velocity of the new fan coil is designed too high,a low-temperature area with poor thermal comfort will be generated vertically down the air outlet.
