摘要 在工程设计过程中以节约造价及选用运行费用较低的系统方案为前提，夏季空调采用了三级蒸发冷却的系统处理过程, 既满足了人员的新风量需求又承担了室内冷负荷。在场馆满员和采用内遮阳措施的情况下，采用上述机组送风，可以将室内温度控制在27 ℃，室内相对湿度控制在57%左右。 关键词 蒸发冷却 绝热过程 间接蒸发 直接蒸发 Application of multi?stage evaporative cooling to the gymnasium of Xinjiang Traffic Vocational Technical College By Du Wei Abstract With the prerequisite of saving possibly more initial investment and operating costs in the design stage, adopts the triple-stage evaporative cooling air conditioning system in summer, which both meets the fresh air standard and the requirement of indoor cooling load. In the condition of the gymnasium at full load and adopting internal sun-shading devices, with the supply air from this unit, the indoor temperature can be controlled at 27 ℃, and the relative humidity 57%.
