A kind of central air-conditioning host cleaning solution and cleaning method

Abstract

The application relates to the technical field of scale and rust removers, and specifically discloses a cleaning solution and a cleaning method for a central air-conditioning main unit. The cleaning solution includes pickling agent, metal protecting agent 1, metal protecting agent 2, metal protecting agent 3 and pickling neutralizer. The method of using it to clean the main unit of the central air conditioner is divided into six steps, including: S1, put soft water into the pipeline of the main unit of the central air conditioner for circulation, add pickling agent and then clean it circularly; S2, add metal protective agent and then clean it circularly ; S3, after adding the metal protective agent for two cycles and cleaning; S4, after adding the metal protection agent for three cycles and cleaning; S5, after adding the pickling neutralizer, making the cleaning solution neutral and draining the cleaning solution; S6, using soft water for circular rinsing The pipeline of the central air-conditioning main unit, so as to complete the cleaning. Using this cleaning solution for cleaning can reduce the problems of acid corrosion and cross corrosion between metals in the cleaning process of the central air-conditioning main unit, thereby prolonging the service life of the central air-conditioning main unit and cleaning effect is cleaner.

Description

technical field [0001] The present application relates to the technical field of descaling and derusting agents, more specifically, it relates to a cleaning solution and a cleaning method for a central air-conditioning main unit. Background technique [0002] The cleaning water treatment of central air-conditioning mainly refers to the cleaning and maintenance of the central air-conditioning water system. The water system of the central air conditioner is divided into cooling water system and chilled water system, in which the cooling water system mainly relies on cooling towers to dissipate heat. In the cooling tower, the water drips and splashes into countless small water droplets or flows in the form of a film on the surface of the filler, fully contacts with the air, and brings a large amount of dust, microorganisms, soluble salts and corrosive gases in the air into the cooling water, making the concentration of impurities in the water In addition, due to the continuous...

Problems solved by technology

In order to quickly complete the cleaning task, the traditional process generally adopts the method of strong acid cleaning. In this process, strong acid is easy to corrode various metals, and cross-corrosion between various metals, such as patina, copper plating, etc., this corrosion will Causes copper pipes to wash and leak, resulting in hundreds of thousands or millions of losses
