Energy management and intelligent control-based solar cooling tower

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 speed regulating 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 very common water 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 pumps that supply water to the cooling tower and the fans of the cooling tower are driven by electric motors. The level of automation control is relatively low. The capacity is excessive all the year round, and a large amount of electric energy is consumed to drive water pumps and fans every year, so there is a lot of room for energy saving. [0003] Solar energy has the advantages of being inexhaustible and inexhaustible, and is an ideal renewable energy source. The solar photovoltaic power generation system has a simple structure, ...

Problems solved by technology

However, the current existing control methods are to separately adjust the water pump motor and the fan motor separately, and there is no coordinated control between them. Although the two isolated loads of the water pump and the fan can respectively achieve a certain degree of energy-saving operation, but from Looking at the entire system of cooling tower operation, the cooling efficiency of the cooling tower has not been fully utilized, and there is still a lot of room for energy saving in the entire cooling tower system
