Abstract

The invention relates to the technical field of information and control, and relates to an automation technology, in particular to an integrated optimization control method for a circulating water system. The method comprises the following steps of: detecting an ambient temperature, ambient humidity, a circulating water cooling tower inlet temperature, an outlet temperature, cooling water pump energy consumption and cooling tower fan energy consumption by using a control system; controlling the flow quantity of a cooling water pump and the air quantity of a cooling tower fan in a variable frequency speed control mode; calculating the optimal regulating quantity of the air quantity of the cooling tower fan and the flow quantity of the cooling water pump in order to reach the lowest energy consumption under the condition of the conventional heat exchange quantity required by actual production according to acquired parameters; and controlling terminal equipment by using a frequency conversion actuating mechanism. The method has the advantages of reducing energy consumption, saving energy and water, and the like, and can be widely applied to occasions where cooling towers are used.

Description

technical field [0001] The invention relates to the field of information and control technology, relates to automation technology, and specifically refers to a comprehensive optimization control method in a circulating water system. technical background [0002] The cooling system is a common equipment in the industry. The principle of the cooling circulating water system is to replace the heat of the cooling equipment with low-temperature water through the circulating water pump, and dissipate the displaced heat to the atmosphere in the cooling tower to achieve the cooling equipment. Purpose. The energy-consuming equipment of the cooling circulating water system includes circulating water pumps and cooling tower fans. According to the principle of heat transfer, the heat exchange amount of cooling equipment: [0003] W=dT×Q [0004] W-heat exchange capacity [0005] dT- temperature difference between inlet and outlet of cooling equipment [0006] Q-cooling equipment fl...
