The invention relates to refrigeration engineering and can be used in refrigerators of food, meat and milk, fruit and vegetable industry and at trade enterprises for air cooling in refrigeration chambers. A jet air cooler with frost removal comprises axial fan, perforated rotary barrel, round that one panels are placed, there have ribs at outside and at inside, with channels in which cooling agent boils, brushes for frost removal. The barrel has two slots provided in its whole length, in those troughs with axle are installed, there rotary spring-loaded brushes are fit for frost removal. The jet air cooler with frost removal is intensive apparatus with continuous operation with high heat dissipation since there frost formed at cooling humid air on heat exchange surface is continuously or periodically removed. Air cooler does not need defrosting. |
