Experiment on the influence of different spraying angles on ambient temperature in high temperature season
Spray is an important temperature control measure in high temperature season.However,due to the complicated im-plementation of spray test,the influence of spray on environmental temperature was not clear.In this paper,the experimental research on different spray angles(15°,20°,25°)of sprayer was designed and carried out.Based on the collected experimen-tal data,the temperature distribution law of point,line and surface in atomization area under typical working conditions was analyzed,and the temperature drop,warehouse surface rainfall and the proportion of spray area lower than spray water temper-ature area under different spray angles were compared.The results showed that the temperature of the atomization area de-creased rapidly at the beginning of the spray.With the saturation of the water mist in the atomization area,the evaporation was stable,and the temperature of the atomization area gradually reached a stable state.The 25°spray angle had the smallest rain-fall on the warehouse surface,and the area below the spray water temperature accounted for the largest proportion,indicating that the 25°spray angle was relatively optimal.
