Air conditioning equipment is prone to dust accumulation and component wear and tear during long-term operation, which can affect the efficiency and even cause malfunctions. This article summarizes the maintenance points for air conditioning units, providing reference for maintenance personnel, and ensuring standardized operations and risk avoidance.
Fan coil unit maintenance and servicing
Cleaning: Regularly clean the water collection tray, air filter, and coil fins to prevent blockages and dust accumulation;
Maintenance: Check the sensitivity of the temperature control switch and the operating condition of the motor, and troubleshoot any abnormal sounds or jams.
3. Maintenance of Cooling Towers
Water replenishment system: Check the water replenishment valve and float switch to ensure stable water level;
Water quality treatment: Regularly add chemicals, test water quality, and prevent scaling and corrosion;
Motor and fan: Check operating parameters, add lubricating grease, and clean the dust on the blades;
Overall cleaning: Regularly clean the internal packing and water collection pan to ensure heat dissipation.
4. Maintenance of ventilation and exhaust equipment
Cleaning: Remove dust from filter screens, louvers, air outlets, and ducts, and clean the fan room;
Maintenance: Check the operating condition of the fans, add lubricating grease, and ensure normal insulation of the motors.
5. Maintenance of Water Pipe System
Pipeline maintenance: Check for corrosion of the pipes, and promptly remove rust and repaint them;
Accessory maintenance: Check the flexibility and sealing performance of valves, calibrate pressure gauges and thermometers;
Pipeline cleaning: Regularly inspect for blockages and promptly remove debris.
6. Maintenance of Motor Pumps
Component Maintenance: Check the concentricity of the coupling, the packing seal, and regularly add lubricating grease to the bearings;
Safety Inspection: Test the insulation resistance of the motor quarterly to identify potential overheating and leakage hazards.
7. Maintenance of the electronic control section
Cleaning: Remove dust from the interior of the electrical control cabinet to prevent short circuits;
Function check: Inspect the wiring and terminal connections, and identify any inaccuracies in the automatic control system;
Safety guarantee: Check the electrical grounding and insulation performance to avoid potential safety hazards.
8. Daily Maintenance and Inspection
Check and record the water temperature and water pressure when the main unit is operating.
Check and record the refrigerant temperature, the temperatures and pressures of the evaporator and condenser when the main unit is operating.
Check and record the main unit's voltage and current, as well as other parameters.
Determine whether the above data is normal and how to adjust.
Check for any abnormal vibrations or noises in the rotating parts.
Check for oil leakage or water leakage in the pipes and joints.
Keep all parts of the main unit clean.
Check the temperature of the motor bearings and the normal operation of the motor sound.
Check and record the motor voltage and current.
Check the inlet and outlet water temperatures and water pressures.
Check if the gaskets are in good condition and if there is any water leakage.
Check if the makeup water, pipe valves are normal.
Check for floating oil, impurities, and other contaminants in the water level and float control switch.
Check the operation and voltage/current of the fan motor.
Pay attention to the cleanliness of the water outlet and the filter screen.
Check the condition of all valves and water pipes.
Check if the makeup water tank and float valve are normal.
Record the daily inspection in the daily inspection record sheet, and record once every 4 hours.
