Central Air Conditioning Maintenance Project

Air Duct Cleaning

Clean and disinfect central air conditioning ducts, return air ducts, fresh air ducts, air handling units, and air duct accessories.
Central air conditioning distributes treated air into rooms via sealed ducts and outlets. Outdoor air contains various suspended particles that are not fully filtered by the central air conditioning, allowing fine dust to enter the ducts and adhere to the interior walls. Over time, this accumulates into a significant amount of dust, directly impacting the air filtration and fresh air circulation of the central air conditioning. Additionally, due to the concealed nature of the ducts and their suitable temperatures year-round, they become breeding grounds for rodents, cockroaches, and other pests, as well as for fungi and legionella, among many harmful pathogens. This poses a direct threat to human health, making them a silent killer for humans.

Water System Cleaning Treatment

Reasons for Water System Cleaning and Maintenance:

The cooling water system primarily relies on the cooling tower for heat dissipation. As the water freezes in the cooling tower and then drips and flows, it comes into ample contact with the air, carrying a significant amount of dust, microorganisms, soluble salts, and corrosive gases into the cooling tower. This leads to a continuous increase in the concentration of impurities in the water, posing numerous hazards to the operation of the central air conditioning system.

Hazardous Indicators: Dust, salts, bacteria, dissolved oxygen, etc. → Lead to scale, algae, and rust particles → Accumulate in main unit copper pipes, filters → Reduce circulation speed → Poor heat dissipation → Inefficient refrigeration → Energy waste, shortened equipment lifespan.

A refrigerated water system is a sealed system; over time, dissolved oxygen in the water can easily cause tube blockages, as well as corrosion of the unit and pipeline accessories, leading to a decrease in cooling capacity and premature equipment damage, which directly affects the normal operation of the central air conditioning system.

Hazard Manifestation: Water corrosion of pipe inner wall → Rust sludge formation → Clogs main and fan coil → Leads to coil explosion or loss of cooling effect → Energy waste → Shortens equipment lifespan.

Central Air Conditioning Water Treatment Effect:

明显 enhance cooling performance, reduce accidents; significantly cut costs, diminish expenses; protect equipment, extend service life; greatly save operational costs; environmentally friendly emissions, beneficial to health.

Cleaning of Main Engine Copper Tubes

Central air conditioning units include copper tubes for evaporators, condensers, absorbers, and various heat exchangers. After long-term operation, the walls of the evaporator, condenser, absorber, or heat exchanger copper tubes may accumulate a significant amount of scale, rust, and sludge, leading to tube blockage and a substantial decrease in the air conditioning unit's performance, potentially causing it to freeze up.

Aluminum fin cleaning

Outdoor unit aluminum fin contamination in air-cooled air conditioning units can lead to increased pressure in the refrigerant system, incomplete liquefaction of the refrigerant, excessively high condensation temperature, and ultimately, excessively high evaporation temperature in the air conditioner, resulting in poor cooling performance. The energy efficiency ratio decreases, and power consumption increases significantly. Prolonged operation can damage the compressor.

Aluminum fin cleaning includes physical and chemical cleaning methods. The frequency of physical cleaning should be determined based on the quality of the equipment's operating environment. When employing chemical cleaning, caution must be exercised to prevent potential damage to the aluminum fins caused by improper chemical cleaning.

Air Conditioning Terminal Cleaning

Air conditioning terminal units may experience reduced service life over time due to the accumulation of various impurities, oil stains from the air, dust, and other factors.
Air conditioning terminal cleaning includes the cleaning of terminal frames, motors, fans, pipeline filters, condensate trays, and cooling coils, etc.
Pipe filters are designed to remove impurities from chilled water, preventing clogging in coils; condensate trays primarily facilitate the drainage of condensate; and surface condensers mainly transfer heat or cold, maintaining excellent conductivity.

Cooling Tower Cleaning

Cooling towers are crucial components of the central air conditioning circulating system. Being installed outdoors, various dust and fungi can enter the cooling system through the cooling tower, posing a significant threat to public health due to the proliferation of microorganisms and the spread of pathogens. Establishing a regular sterilization, drainage, and flushing regimen is essential to ensure the safety of the air conditioning and its surrounding environment.
