Do you know that commercial central air conditioning includes commercial plazas, conference centers, hotels, hospitals and other large places? The commercial central air conditioning is the way of air duct supply, with a host can control a number of different rooms, can effectively improve the air in the room, prevent the occurrence of diseases, in order to ensure the normal use of commercial central air conditioning, to clean the commercial central air conditioning in time, then how to clean the commercial central air conditioning? The following and Suzhou central air conditioning maintenance small series together to see!

First, how to clean commercial central air conditioning

The commonly used physical cleaning method is to choke the air, so that tools such as punches, rubber plugs, nylon brushes and round steel pass through the pipeline of the heat exchanger to remove deposits and infarcts in the pipeline. Open the end cover of the body, hit the copper pipe one by one with the gun, wash the biological clay and rust from the wall of the pipe, and rinse with high pressure water after the shelling is finished. And, completely eradicate the side of the water chamber, end cover of the inner wall of all rust, dirt block, coated twice anti-rust paint, play the role of anti-rust, decontamination, antifouling.

Commercial central air conditioning through the action of chemical agents to dissolve, decompose, scatter or peel the accumulation in the cleaning equipment cleaning method. Commonly used chemical cleaning methods are pickling, alkali washing, complexing agent cleaning, sterilization cleaning and so on. Chemical cleaning is generally used to remove hard scale, curves, contact deposits in equipment and pipelines. Open the suction grille, slowly pull down while holding two buttons, pull the hook of the air filter to pull out diagonally, remove the filter, cleaning method: remove the dust with a vacuum cleaner, or wash with water or warm water, when there is too much dust, use a soft brush to put in neutral detergent, wash and throw away the water

In order to prevent decolorization and deformation, please remember not to rinse with hot water above 50 ° C and do not dry on the fire. The filter could catch fire. Be sure to install an air filter after cleaning. The central air conditioning installation project in the upper part of the suction grille to install an air filter, so that the suction grille fixed on the suction grille on the back of the projection slide to the inside, the suction grille to install an air filter on the suction grille, close the suction grille. Contrary to step 1, after pressing the filter signal reset key of the control panel, the attention mark for central air conditioning cleaning disappears. When there is too much dust in the environment, the air filter is cleaned once every six months.

Commercial central air conditioning has been used for a long time, and the chilled water, cooling water system, freezing body and cooling disc of the blower can not avoid the problem of scale, rust and dust. The inner wall of the equipment rusts and falls due to corrosion, even if it is perforated, the falling rust often clogs the coil, reducing the refrigeration effect, and the existence of corrosion greatly shorens the life of the equipment, improves energy consumption, and increases the operating cost. In order to make the commercial central air conditioning system operate in good condition, it is necessary to maintain the air conditioning system.
