Abstract
- According to the problem of high energy consumption and high refrigeration value lost existed in the cooling system during the mine construction period of new mine in Shandong Yuncheng, the paper provided measures to improve the insulation structure of cooling air transportation tube, to optimize the structure of air conditioner, to improve the spraying mode of air conditioner and others. After the improvement, the comprehensive refrigeration value lost of the air conditioner was reduced to the previous 1.1%, the supply and return water temperature difference of air conditioner was increased about 10 °C, the water flow was reduced to 1/4 of the previous water flow and the input power of water pump could be reduced to 41.7% of the previous power. Meanwhile, the theoretical performance coefficient of the refrigeration unit could be increased about 15% and the high efficient and energy saving operation of the cooling system could be realized.
