What is the cleaning method of hotel air conditioning?

Central air conditioning cleaning is to detect the pipeline first, then clean it with cleaning robot, vacuum it, and finally disinfect it.

Cleaning of central air conditioning generally includes freezing water, cleaning and descaling of cooling system, water treatment, cleaning of inner cavity of lithium bromide unit, replacement of new solution, regeneration of old solution and cleaning of fan coil of central air conditioning. It is difficult to clean the scale and blockage, and the pipe blockage is serious, even exceeding 20% of the tube bundle, and the heat exchanger with small diameter (the pipe diameter is below 12 mm).

(1) sterilization: by adding bactericide to the circulating system, all kinds of bacteria and algae in the circulating water are removed.

(2) Mud stripping: a stripping agent is added to strip the biological mud in the pipeline, and the biological mud is circularly cleaned.

(3) Chemical cleaning: chemical cleaning agent and dispersant are added to clean the floating rust, scale and oil stain in the pipeline system, and the floating rust, scale and oil stain are dispersed and discharged to restore the cleanliness of the metal surface.

(4) Pre-filming on the surface: A pre-filming agent is added to form a dense polymer protective film on the metal surface, which plays an anti-corrosion role.

(5) Daily maintenance: corrosion inhibitor is added to avoid metal rusting, and scale inhibitor is added to prevent calcium and magnesium ions from crystallization and precipitation through comprehensive action. And regular sampling, monitoring water quality.
