热风送风温差对室内环境的影响

Impact of Heating Supply Air Difference on Indoor Environment

为了降低空调系统的能耗,本文以某一典型的空调办公室为研究对象,,采用数值计算软件Fluent模拟冬季室内气流组织的分布状况,对比分析了在相同的热负荷时不同的送风速度和送风温差对室内环境的影响,确定了在既定的热负荷时,在满足规范规定的送风温差的前提下,大温差送风可以提高人体活动区的温度,降低人体活动区的风速,为其他相同或类似房间空调系统的选择和气流组织设计提供参考。

In order to reduce the energy consumption of air conditioning system,by applying the numerical calculation software FLUENT,the paper simulates the air distributions in winter in a typical air conditioning office,and analyzes the impact of different air velocities and supply air temperature difference on the indoor environment at the same thermal load.It concludes that a large difference between supply air temperature and room temperature can enhance the temperature of people＇ s surroundings at the specified thermal load and the temperature difference which is allowed in relevant standards.The paper provides suggestions for selecting an air-conditioning system and designing air distribution in the same or similar rooms.
