Experimental study on the cooling effect by fine mist in long and narrow space with high temperature

Regarding the long and narrow space at high temperature,it is difficult to decrease the temperature to a satisfaction level only by ventilation,but it is effective to use fine mist as an assistance.In this paper,the cooling effects at different spray ways and pressure are studied by experiment.It is showed that spray ways and pressure have a great influence on cooling effect for long and narrow space at high temperature.
