摘要:

利用CFD技术对某核化工项目厂房设备室通风与设备传热情况进行了模拟分析,对比了不同保温方式、进排风口位置对混凝土墙体温度的影响。探究了满足热环境要求时的最小进风量。结果表明,对设备进行保温可以有效地降低发热体对混凝土结构的影响,从而减小进风量,达到节能的目的。

Abstract:

Simulates and analyses the ventilation and heat transfer of the equipment room in a nuclear chemical engineering plant by using CFD technology, and compares the effects of different thermal insulation methods and the positions of air inlets and exhausts on the temperature of concrete walls. Explores the minimum intake air rate to meet the requirement of thermal environment. The results show that the thermal insulation of the equipment can effectively reduce the influence of heating elements on the concrete structure, so as to reduce the intake air rate and achieve the purpose of energy saving.

Keywords:ventilation,heatingelement,heattransfer,thermalinsulation,energysaving,nuclearchemicalengineering
