Abstract

The invention discloses a control method and device of cooling tower water supply temperature set values. The control method comprises the following steps that history data and current data of a cooling water system, a nominal wind quantity of each cooling tower fan and a nominal water flow of each cooling pump are obtained; according to the history data, and the nominal wind quantity of each cooling tower fan and the nominal water flow of each cooling pump, related parameters in a cooling tower water supply temperature set value model are fitted by a genetic algorithm to obtain the related parameters; and according to the related parameters, and the current data, the nominal wind quantity of each cooling tower fan and the nominal water flow of each cooling pump, the cooling tower water supply temperature set values are iterated by the genetic algorithm to obtain the cooling tower water supply temperature set values. According to the technical scheme, the control method can enable the comprehensive energy consumption of a central air conditioner cooling water system to be lowest, and realizes the energy saving optimization of the cooling water system and a central air conditioning system.

Description

technical field [0001] The invention relates to the technical field of central air conditioning, in particular to a method and device for controlling a set value of water supply temperature of a cooling tower. Background technique [0002] At present, the research on the central air-conditioning system shows that for every 1°C decrease in the condensation temperature of the condenser of the refrigeration unit, the energy efficiency of the refrigeration unit can be increased by 3% to 4%. At this time, in order to reduce the condensation temperature of the condenser of the refrigeration unit, the temperature of the cooling tower water supply also needs to be reduced accordingly. However, the reduction of the water supply temperature of the cooling tower will inevitably lead to an increase in the operating speed of the cooling tower fan and the cooling pump, resulting in an increase in the energy consumption of the cooling tower fan and the cooling pump. Therefore, aiming at t...
