Problems solved by technology
Cooling tower fans are usually not fully turned on in winter in order to save energy, but this start-up method has the following problems: 1. The temperature of the cooling return water with and without fans in the cooling tower affects the cooling effect; 2. The two typhoons only turn on When there is only one cooling tower, a huge wind tunnel will be formed at the outlet of the fan that is not turned on, which will cause a short circuit of the airflow and affect the air intake and cooling effect of the other cooling tower; three, when only one of the two cooling towers is turned on, the heat dissipation area will not be fully utilized , the cooling capacity is not fully utilized

The invention discloses a combined control system for cooling towers. The combined control system comprises a first fan, a second fan, a third fan, the first cooling tower, the second cooling tower and the third cooling tower. The first fan, the second fan and the third fan are arranged at the upper end of the first cooling tower, the upper end of the second cooling tower and the upper end of the third cooling tower correspondingly, and connected in series. According to the combined control system for the cooling towers, intelligent optimal control over the cooling towers is adopted, the evaporation amount of cooling tower circulating water and electricity cost of the cooling tower fans can be effectively reduced, and the comprehensive electricity saving percent is 20%-50%.
Description
technical field [0001] The invention relates to the field of energy saving and environmental protection of cooling towers, in particular to a combined control system of cooling towers. Background technique [0002] At present, the fans in industrial cooling towers have been operating at power frequency, and the operating frequency cannot be adjusted in real time according to the load and environmental changes. different. In particular, the ambient temperature and humidity differ greatly in the morning and evening, which means that the actual outlet water temperature of the cooling tower will also change accordingly. The cooling tower fan always runs at full power at power frequency regardless of changes in the weather and the load at the cooling load end. When the cooling water temperature of the system is close to the wet bulb temperature, the fan cannot adapt to the change, and still operates at the power frequency. At this time, the energy consumption cannot lower the t...
