FIELD: refrigerating engineering. SUBSTANCE: water and liquid carbon dioxide are introduced and sprayed in supersonic air flow cooled by adiabatic expansion to obtain aqueous aerosol with centers of crystallization. To intensify snow production process, water and liquid carbon dioxide are introduced by their simultaneous admission to different sections of ultrasonic vibration concentrator accommodated in mixing chamber. EFFECT: intensified snow production process. 1 dwg
