| This research was carried out to find out spray characteristics of 3 types of spray nozzle to be used for greenhouse cooling. Following results were obtained from this experimental study. Water amounts sprayed with each nozzle were increased with the spraying pressure. However the increment of sprayed amount with the increase of spraying pressure were not consistent regardless of nozzle types. For the whole tested spraying pressures of nozzle-type I, II, III, the minimum droplet sizes were about 1.7~2.5$mu$m, 1.7~2.2$mu$m and 1.7~2.2$mu$m, respectively, and the maximum droplet sizes were about 44~60$mu$m, 52~71$mu$m and 45~61$mu$m, respectively, and the average droplet sizes were about 23~38$mu$m, 19~24$mu$m and 17~25$mu$m, respectively The most appropriate spraying pressures of nozzle-type I, II, III were analyzed to be 70kgf/$ extrm{cm}^2$, 30kgf/$ extrm{cm}^2$ and 30kgf/$ extrm{cm}^2$, respectively, and their sprayed amounts were about 124mL/min, 103mL/min and 84mL/min, respectively, and average droplet sizes were 22.6$mu$m, 21.8$mu$m and 20.6$mu$m, respectively. Also, with the order of nozzle-type I, II, III, droplet size distributions less than 30$mu$m were 95.4%, 85.7% and 79.0%, respectively, and the distributions larger than 40$mu$m were 0.2%, 1.28% and 1.67%, respectively. However most all of the droplet size were less than 50$mu$m. |
