After prolonged operation, the central air conditioning system inevitably experiences issues such as scale, corrosion, and dust in the chilled water, cooling water systems, refrigeration main unit, and heat dissipation fins of the fan, which severely affect the normal operation of the air conditioning system.
Central Air Conditioning Cleaning Procedure
Central air conditioning cleaning typically includes the cleaning and descaling of the chilled water and cooling systems, water treatment, cleaning of the interior of the lithium bromide units, replacement of new solutions, regeneration of old solutions, and cleaning of the central air conditioning fan coils. Scale buildup can be very hard and difficult to clean, leading to severe blockages that may exceed 20% of the tube bundles and small-diameter heat exchangers (diameter less than 12mm).
1. Sterilization: By adding sterilizing agents to the recirculating system to clean various bacteria and algae from the circulating water.
2. Sludge Removal: Add a stripper to remove biological sludge from pipes, and then wash it out through recirculation.
3. Chemical Cleaning: Add a chemical cleaner and dispersant to clean rust, scale, and oil污 from the pipeline system. Disperse and return to a clean metallic surface.
4. Surface Pre-film: The addition of a pre-film agent forms a dense polymer protective film on the metal surface, providing anti-corrosion protection.
5. Oral Daily Maintenance: Add corrosion inhibitors to prevent rust on rabbit metal; add scale inhibitors to prevent calcium and magnesium ions from crystallizing and precipitating through comprehensive action. And regularly take samples to monitor water quality.
Why isn't the office's central air conditioning working in the summer?
Windows and doors left open too wide result in heat loss through convection; closing them reduces ventilation.
2. External unit poor heat dissipation: Poor ventilation at the external unit location, sunlight exposure on the external unit, excessive dirt on the external unit radiator
3. Refrigerant Leak
