Problems solved by technology
This method has the following defects: 1) control the switch of the fan of the cooling tower by the outlet water temperature of the cooling tower, or control the switch of the cooling tower fan one by one, the system will appear mixed water phenomenon
2) The fan of the cooling tower is frequently turned on or off, which will reduce the life of the motor and electrical components
3) The outlet water temperature of the cooling tower fluctuates greatly, and the high energy consumption of the ice machine will also increase the outlet water temperature
4) The cooling capacity of the ice machine cannot be optimized

The embodiment of the invention discloses an operation control system and an operation control method of a cooling tower of ice machine. The operation control system comprises a water chilling unit, afirst temperature sensor, a second temperature sensor, a programmable logic controller and an artificial intelligence controller. According to the technical scheme provided by the operation control system and the operation control method of the ice machine cooling tower, the frequency conversion of a fan of a cooling water tower is further controlled by comparing the outlet water temperature of the cooling water tower with the wet bulb temperature on the exterior of the water chilling unit and determining the specific value of the temperature change trend according to the outlet water temperature and the current operating frequency of the fan, and the operation mode of the fan is determined according to the control output value of the programmable logic controller and the system setting output value of the operation control system, so that the purpose of saving the energy consumption of the ice machine is achieved by using the heat dissipation area of the cooling tower to the greatestextent, the water mixing phenomenon of the system is avoided, and the stable operation of the system is ensured.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of ice machine cooling, and in particular to an operation control system and an operation control method of an ice machine cooling tower. Background technique [0002] At present, most production enterprises will be equipped with ice machines and cooling towers to cool high-temperature equipment or products. [0003] In the prior art, the cooling water of the ice machine controls the opening and closing of the fan of the cooling tower through the outlet water temperature of the cooling tower. When there are multiple cooling towers, it is necessary to open or close the fan of each cooling tower one by one. fan. There are following defects in this method: 1) control the switch of the fan of the cooling tower by the outlet water temperature of the cooling tower, or control the switch of the fan of the cooling tower one by one, the water phenomenon will appear in the system. 2) The fa...
