Central air conditioning condenser cleaning procedures and precautions

Central air conditioning condenser can easily scale, the normal cooling in the summer of treatment should be done daily, otherwise it runs in an environment of high hardness, dissolved in water in the circulating water system inorganic salt will crystallize as the temperature rises precipitated the formation of scale on the wall of the condenser heat transfer surface, resulting in reduced heat exchange efficiency. At the same time hard scale is increased, the increase in energy consumption will increase when the hard knot scale 1mm thick 6 to 10. As the water soil, sediment, soil humus formation, with bacteria, algae and other microorganisms and the formation of secretions biological slime, will be attached to the condenser heat transfer tubes formed on the walls dirt, causing severe pipeline clogging; and dirt, slime will affect the heat exchange efficiency, more power can cause high voltage operation, causing severe overpressure shutdown . All this has seriously affected the normal operation of the condenser. Condenser cleaning is divided into physical cleaning and chemical cleaning, general physical cleaning with high pressure water jet condenser brass dirt cleaned out; if scaling a hard scale, should be carried out chemical cleaning, the scale can not be physically removed.

In order to optimize the condenser run in the state, it must condenser specialized chemical drug treatment, removal of scale, rust, slime, antiseptic and anti-corrosion treatment, reduced to clean metal surfaces.

Operating procedures:
(1) Close the valve out of the water, open the drain valve, check valve is closed and out of the case.
(2) Open the condenser cover, take a little scale on the brass surface with descaling agent do different concentration ratio of cleaning tests.
(3) The method by low prices, connected properly cleaning pump.

(4) the use of an external pump, to the bucket filled with water, start the cleaning pump cycle to smooth water.
(5) several times to slow the bucket plus YX-22 detergents. After repeated washing with tap water cycle to PH value to about 7.
(6) rinsed with tap water cleaning pump.
(7) Open the cover using Yaxin automatic machine guns pass through gun.

First, the physical cleaning

1.1 host physical gun suitable for water walking through the sediment and rust clogging the tube more serious equipment, such as a severe blockage before chemical cleaning equipment must first pass a physical gun.
1.2 Close out of the water valve, open the drain valve, check valve is closed out, the water will drain and clean the heat exchanger.
1.3 Opening the need to clean up parts of the cap, taking pictures, taking dirt samples for analysis.
1.4 The use of brass Yaxin through automatic machine guns, water cannons, and other tools to clear the rod clean.
1.5 Water indoor dirt floor clean, anti-rust paint brush, paint dry, take pictures.
1.6 test standard brass without clogging silt cleaning rate of 95%
1.7 open site restoration, pressure test watertight.

Second, chemical cleaning
The method uses a single professional cleaning cycle, using efficient detergents for Copper Tube ten times lower than that of an inorganic acid, based on the effective protection of equipment on the fast cleaning, descaling. After washing of brass pre-film treatment, can greatly slow down the corrosion rate of the device.
