目前大多数集中空调机喷水室,都装有口径为d_c=2～5毫米的Y-1型标准喷嘴。为减少该种喷水室管理上的劳动费用,苏联中央工业建筑科学研究所,曾经研制了大口径(d_c=5～16毫米)喷嘴。在具有与Y-1型喷嘴几乎同样的喷雾质量的实际多种运行条件下,它都不堵塞。同时,也会遇到某种情况,需要提高现有喷水室效率,而不要增加喷嘴口径。这也是喷水室全年不连续工作的公用建筑空调系统的特点。上述分析表明了,提高喷水室效率的最简单方法就是改善喷嘴喷雾质量,以便扩大空气和水的接触表面。同时也明确了,对于单一入口通道的离心喷嘴,为达此目的,需要把旋转小室的口径提高到
At present, most spray booths of centralized air conditioners are equipped with Y-1 standard nozzles with a diameter of d_c=2 to 5 mm. In order to reduce the labor costs in the management of the water spray chamber, the Soviet Central Institute for Industrial Construction Research has developed large-diameter (d_c = 5 ~ 16 mm) nozzles. It does not block under practically many operating conditions with almost the same spray quality as the Y-1 nozzle. At the same time, there will be some situations where it is necessary to increase the efficiency of the existing spray chamber instead of increasing the nozzle diameter. This is also the characteristic of the public building air-conditioning system where the water spray chamber does not work continuously throughout the year. The above analysis shows that the easiest way to increase the efficiency of the spray chamber is to improve the quality of the nozzle spray in order to expand the air and water contact surfaces. It is also clear that for a single inlet channel of a centrifugal nozzle, for this purpose, the diameter of the rotating chamber needs to be increased to
