Abstract

According to the principle of atomization cooling,a 80t/h experimental counter-flow no-padding spraying cooling tower was established.And through four experimental conditions the influence of the inlet air dry-bulb /wet-bulb temperature on cooling effect in spraying cooling tower was analyzed.The results showed: when inlet air dry-bulb temperature increased by 2℃,the cooling range reduced by only 0.2℃ and the cooling efficiency only reduced by 3.2%,when inlet air wet-bulb temperature increased by 1.8℃,the cooling range reduced by 0.8℃ and the cooling efficiency reduced by about 13.4%,which showed that the inlet air wet-bulb temperature had a larger impact on the cooling effect than that of the inlet air dry-bulb temperature in spraying cooling tower.
