| Abstract: | Compressed air has been widely used in industrial processes, however, the main reason for the low efficiency of pneumatic system is the low efficiency of the compressed air production. Directly spray cooling compressed air could achieve the goal of energy conservation and emissions reduction by reducing the compressing energy consumption and improving the efficiency of pneumatic system. According to the model, the properties of cooling parameters, such as ways of compressed air, inlet and outlet temperature of compressor, diameter of spray particle and different ratio volumes, which have the effects on the compressor power consumption and energy saving efficiency have been analyzed. Under the different ratio volumes, the highest energy-saving efficiency of directly spray cooling compressed air can reach 38.8%. As a result, directly spray cooling compressed air provides an effective solution for power-saving in pneumatic system. |
