Abstract

The invention discloses an energy management and intelligent control-based solar cooling tower, which comprises a solar battery, a first motor, a water pump, a second motor and speed reducer, a fan, a hybrid converter connected with the output end of the solar battery, an intelligent controller, and a sensor group; the output end of the hybrid converter is connected with the input ends of the first motor and the second motor and speed reducer; the signal output end of the sensor group is connected with the signal input end of the intelligent controller; the output end of the intelligent controller is connected with the signal input end of the hybrid converter; and the signal output end of the hybrid converter is connected with the signal input end of the intelligent controller. In the control process, the intelligent controller reasonably distributes the flowing direction of the electric energy through the hybrid converter by an energy management method, and performs intelligent speedregulating control on the first motor and the second motor and speed reducer by a water inlet temperature negative feedback method and a minimum enthalpy difference control method, and an energy-saving effect is achieved on the premise of ensuring operating reliability.

Description

Technical field

[0001] The invention relates to a cooling tower, in particular to a solar cooling tower based on energy management and intelligent control. Background technique

[0002] Cooling tower is a widely used water resource recycling equipment. Its main function is to exchange heat between cooling water containing waste heat and air in the tower to reduce the water temperature to the required temperature for recirculation. At present, the water pump for water supply to the cooling tower and the fan of the cooling tower are all driven by electric motors. The level of automation control is low. The working state of the cooling tower is single and does not have the ability to automatically adjust with the changes of various parameters. The capacity is always surplus and consumes a large amount of electricity used to drive water pumps and fans every year, and there is a lot of room for energy saving.

[0003] Solar energy has the advantages of inexhaustible and inexhaustible, ...
