基于实测对冷却塔出水温度的4个影响因素进行了相关性分析,建立了冷却塔出水温度统计模型,提出了最佳冷却塔出水温度控制策略。结合某实际工程,在冷水机组、冷却水泵及风机的耗功率数学模型确定及不同的系统负荷率及室外湿球温度条件下,对比分析了冷却水系统在6种不同运行控制策略下的能耗,确定了最佳控制策略。
Based on the measured data, four influencing factors of the cooling water temperature in the cooling tower were analyzed. The statistical model of water temperature in the cooling tower was established, and the control strategy of the outlet water temperature of the cooling tower was put forward. Combined with a practical project, under the condition of mathematical model of power consumption of chiller, cooling water pump and fan and different system load rate and outdoor wet bulb temperature, the energy consumption of the cooling water system under six different operation control strategies is compared and analyzed. , Determine the best control strategy.
