Problems solved by technology
However, because electrical equipment usually needs to run for a long time, in different application scenarios, such as some special applications, including harsh spaces, coal mines containing sulfur dioxide, dust and other substances, the traditional prevention or cleaning methods cannot fit the actual application scenarios , and automatically clean up in time according to the fouling situation of the unit. At the same time, due to the negligence of manual cleaning operations, it is easy to accumulate dirt on the unit and cannot be effectively cleaned.

The invention relates to an evaporative cooling unit and a descaling control method and device of the evaporative cooling unit. The method comprises the steps that a detection result of circulating cooling water is obtained; a cyclic decoupling and coupling judgment result of a heat exchanger is generated according to the detection result; and when it is determined that the scale prevention mode starting condition is met according to the cyclic decoupling and coupling judgment result, a guide rail and / or a pollution discharge device of the evaporative cooling unit are / is controlled to conductdescaling operation. Through the adoption of the method, in different actual application scenes, the guide rail or the pollution discharge device is used for carrying out descaling treatment on the evaporative cooling unit in time, the operation that workers manually use a descaling tool to carry out descaling is not needed, the descaling treatment efficiency is improved, and unit dirt can be effectively removed.
Description
technical field [0001] The present application relates to the technical field of electrical control, in particular to an evaporative cooling unit and a descaling control method and device for the evaporative cooling unit. Background technique [0002] With the development of electrical control technology and the wide application of evaporative cooling units in different electrical equipment with refrigeration needs, in order to ensure the long-term normal operation of electrical equipment, the scaling problem of evaporative cooling units has been paid more and more attention. [0003] Aiming at the fouling problem of the unit, traditionally, the circulating cooling water is softened, or the method of regular manual cleaning is adopted. However, because electrical equipment usually needs to run for a long time, in different application scenarios, such as some special applications, including harsh spaces, coal mines containing sulfur dioxide, dust and other substances, the tra...
