The cleaning of central air conditioner condenser2012-5-2
The condenser of central air conditioner is easily scaling and should be done water treatment in the summer. Otherwise, running in the environment of the high hardness, with temperature increasing, inorganic salts which soluble in water will precipitation in circulating water system and form scale on the wall of the condenser, and resulting in heat exchange efficiency low. Hard scale increases will result in more energy consumption.
Due to the dirt and biological slime will attach to the condenser and form scale, which will make condenser coils blockage. The dirt and slime will affect the heat exchange efficiency, even overpressure shutdown. All of which has seriously affected the normal operation of the condenser.
The condenser coils cleaning have physical cleaning and chemical cleaning, physical cleaning use of high pressure water jet to clean out the dirt of the condenser coils. If the the fouling is hard scale, it need chemical cleaning. In order to make the condenser running in optimal condition, it must specifically chemical drug treatment to remove scale and restored to a clean metal surface.
1. Close the valve of cooling water tube, of the thermometer tube, pressure gauge pipe and outfall pipe connection with the tank made of small-circulation system.
2. Add the acid inhibitor, the pharmaceutical for the dedicated copper corrosion inhibitor, it is attached to the condenser metal on the inner wall to prevent the acid and metal react.
3. Adding the solid acid cleaning agent, cleaning calcium carbonate scale as the main ingredient, cleaning agent is a composite solid organic acid. The amount of cleaning agent according to the amount of equipment scaling.
4. Adding dirts stripping agent (optional), if the condenser equipment scaling thick, add dirt stripper, which promote scale rapid dissolve in water.
5. Adding passivation agent, chemical cleaning in the condenser to residual acid, which prevent the metal surface oxidation and generate secondary rust.
