Central air-conditioning cooling water dosing operation and maintenance control system and its control method

Abstract

The invention relates to a control system for adding chemicals into cooling water of a central air conditioner for operation and maintenance and a control method of the control system. The control system comprises a main controller, a water quality detection device, a blowdown device, a chemical adding device and a cloud platform. The blowdown device is provided with a plurality of driving devices and a plurality of automatic blowdown valves. The chemical adding device comprises a plurality of chemical adding metering pumps, a plurality of chemical adding buckets, a plurality of liquid level testing electrodes and a plurality of liquid level sensors. The cloud platform is provided with a communication module, a wireless router and the like. When the control system is applied, operation steps are simple and reliable, and observation is convenient; various functions such as online detection of the water quality, automatic operation of chemical adding after blowdown, automatic recording and statistics of chemical adding quantity and cloud platform monitoring can be achieved; and the automation degree is high, the control effect is good, and the control system has high application and popularization value.

Description

technical field [0001] The invention relates to the technical field of water quality detection, dosing and sewage treatment of water systems, in particular to a central air-conditioning cooling water dosing operation and maintenance control system with high degree of automation, strong comprehensive functions and easy management and a control method thereof. Background technique [0002] The water quality in the central air-conditioning system is related to the operation stability of the entire system and affects the service life of the equipment in the system. In the prior art, water treatment, electrostatic water processors and chemical addition are generally used for water treatment. Dosing Most of the medicaments use manual dosing method, the sewage discharge effect is not good, and the water quality of the central air conditioner cannot be effectively improved. Moreover, the dosing equipment commonly used in the cooling water system of the central air conditioner does no...

[0002] The water quality in the central air-conditioning system is related to the operation stability of the entire system and affects the service life of the equipment in the system. In the prior art, water treatment, electrostatic water processors and chemical addition are generally used for water treatment. Dosing Most of the medicaments use manual dosing method, the sewage discharge effect is not good, and the water quality of the central air conditioner cannot be effectively improved. Moreover, the dosing equipment commonly used in the cooling water system of the central air conditioner does not record the data of the dosing of the medicament, which leads to the inability to calculate the dosage of the medicament, or Using manual pen records, it is easy for the maintenance personnel to forget to record or there is deviation in the recorded data, resulting in chaotic management and uncontrollable, in severe cases, the dosage of chemicals is too large, resulting in excessive operation and maintenance costs

In addition, in the existing technology, the functions of the chemical barrels used in the chemical dosing equipment are not perfect enough, lack of alarm or other protective measures, resulting in damage to the chemical dosing pump and other equipment due to idling, system disorder, etc., increasing operation and maintenance costs
