蒸发冷却空调在工业厂房的应用研究

Application Research of Direct Evaporative Cooling Air Conditioner in Industry Building

工业厂房内温度往往比较高,由于其生产工艺的特点,生产过程中常常会产生一些有毒、有害气体,随着GBZ1—2002,《工业企业设计卫生标准》等相关标准的提出,采用自然通风降温的方法已很难达到相关标准的要求,而采用传统机械制冷空调则投资、运行费用高,空气质量差。蒸发冷却空调以其自身的特点,在这一领域的应用显示出独特的优点。本实验特建立气候小室,利用直接蒸发冷却空调,采用正压送风的方法对其进行通风、降温,系统地测得了不同条件下,蒸发冷却空调的性能与使用效果,得出了蒸发冷却空调在这一领域应用的可行性与优越性,实验中的结论对蒸发冷却空调设备的优化与运行亦有一定的指导意义。

The temperature in industry building is usually higher, because of the characteristic of the production, some poisonous and noxious matter will be brought out in the production process also. As some standards such as GBZ1-2002 was put forward, the way of nature ventilation in cooling air in industry building has can not be achieved the demand of pertinent standards already, but the investment and operation expense is higher to use the traditional mechanical refrigeration, and the air quality is poor also. DEC air condRioner shows particularly advantage because of itself characteristic in this field. A climate room was building up to carry on the experiment, and used the DEC air conditioner tO ventilate and cool down the air in the room. The performance parameters were measured in different conditions. The result shows that the DEC system is feasible in the field, and some conclusions are useful to optimize the DEC design and its operation.
