FIELD: cooled storage of food stuff. SUBSTANCE: device is provided with liquefied gas supply system including gas reservoir and pipe line with metering unit and fan whose one branch pipe is communicated with atmospheric air supply passage and with recirculating passage and other branch pipe is connected with gas-dynamic siren through air delivery duct. Siren is provided with rod resonator with axial passage, mixing chamber and gas distributing passage. Pipe line and metering unit are connected with axial passage of resonator by means of pipe union located in line of resonator zero displacement at angle of 45 deg relative to its longitudinal axis. EFFECT: enhanced efficiency. 2 dwg
