技术领域 technical field
本发明涉及暖通空调和节能技术领域，是一种多工况复合间接空气处理装置及其空调方法。The invention relates to the technical fields of heating, ventilating, air-conditioning and energy saving, and relates to a multi-working-condition composite indirect air treatment device and an air-conditioning method thereof.
背景技术 Background technique
随着经济的快速发展，发热量大的工业建筑也越来越多，为了满足生产工艺要求，在此类建筑中需设置通风或空调系统。在冬季或过渡季节由于过滤和风管冷凝结露的问题，不能直接使用室外的低温空气带走室内的热量；在夏季或过渡季节此类建筑的通风或空调系统的特点是通风量一般都比较大，因此为了节能，此类建筑的通风空调系统一般都采用直接蒸发制冷技术，人们发现在使用直接蒸发制冷技术时，由于使用的空气都是由室外引进的新风，这样处理的新风量大，在新风处理过程中，会遇到空气过滤困难的问题，当空气过滤的精度较高时，就会堵塞过滤器，造成过滤器清洗频繁；当过滤精度较低时就会造成空气中的悬浮物不能有效的过滤从而进入到直接蒸发制冷填料中，影响制冷效率甚至堵塞填料，使得整个填料报废。With the rapid development of the economy, there are more and more industrial buildings with high heat generation. In order to meet the requirements of production technology, ventilation or air conditioning systems need to be installed in such buildings. In winter or transitional seasons, due to the problems of filtration and condensation in air pipes, the outdoor low-temperature air cannot be directly used to take away indoor heat; in summer or transitional seasons, the ventilation or air-conditioning systems of such buildings are characterized by relatively low ventilation volume. Therefore, in order to save energy, the ventilation and air-conditioning systems of such buildings generally adopt direct evaporative refrigeration technology. In the process of fresh air treatment, it will encounter the problem of difficult air filtration. When the air filtration accuracy is high, the filter will be blocked, resulting in frequent filter cleaning; when the filtration accuracy is low, it will cause suspended matter in the air. It cannot be effectively filtered and enters the direct evaporative refrigeration packing, which affects the refrigeration efficiency and even blocks the packing, making the entire packing scrapped.
