摘　　要：集中热源是室内最重要的热对流源。在房间送风条件一定的情况下,热对流与送风动量流,相互作用实现动量和热量交换,从而达到室内冷却、加热及通风的效果。采用CFD模拟方法,研究了散流器上送风空调系统集中热源分布在室内不同分布位置,对工作区温度场的均匀性影响情况,得到室内发热设备,人员活动区相对风口的合理布置范围。Concentrated heat-source is the most important thermal convection of indoor air. In the room air conditions in certain circumstances, thermal convection and momentum flow, interaction of momentum and heat exchange, so as to achieve the indoor cooling, heating and ventilation. In this paper, through CFD simulations to study the square diffuser air distribution system focused on the distribution of heat distribution in the room different location, work area temperature on the uniformity of the situation, get the indoor heating equipment and personnel activity areas relative to the scope of rational arrangement of air.
