As the flood season approaches and heavy rain becomes frequent, it not only causes inconvenience for travel but also poses higher safety requirements for the operation of large central air conditioning systems. Using central air conditioning during heavy rain can potentially lead to equipment damage, electrical failures, or even safety accidents if not handled carefully. To ensure stable equipment operation and personnel safety, please remember the following usage precautions!
Check the outdoor unit for stability to prevent it from being displaced by strong winds.
Severe storms often come with strong winds, and outdoor units that are not securely installed can easily be blown over or displaced, leading to equipment damage or even causing injury from falling. Suggestion:
l Regularly inspect outdoor machine brackets and screws for rust or looseness.
l Timely reinforcement of outdated equipment.
l If the installation location is found to be unreasonable, it should be adjusted as soon as possible.
To prevent water from reversing into the system and to avoid the electrical control system from getting damp.
Water entering the electrical control box can easily cause serious issues such as short circuits and damage to the mainboard. Suggestion:
l Ensure proper drainage for outdoor unit bases to prevent water accumulation.
l If the equipment is located in a low-lying area, consider adding a waterproof platform or a rain shelter.
l Please select those withElectrical control systems with IP55 and above protection ratings, enhanced waterproof and dustproof capabilities.
l Should water intrusion or wiring aging be detected in the electrical control box, immediate shutdown and professional assistance should be sought.
During thunderstorms, it is recommended to turn off the air conditioning and disconnect the power supply.
Under thunderstorms, air conditioning equipment is prone to lightning strikes, which could lead to a burnt motherboard or electrical accidents. Recommendation:
l Before the thunderstorm arrives, turn off the air conditioner and disconnect the power supply.
l Install qualified lightning protection devices to enhance overall electrical safety levels.
l Avoid forceful operation of air conditioning during frequent lightning periods.
Four: Inspect the refrigerant piping to prevent fluorine leakage.
Heavy rainfall may scour away and cause cracks in connecting pipes or loose joints, leading to refrigerant leakage and affecting cooling efficiency. Suggestion:
l Regularly inspect the pipeline connections for tightness.
l If you notice a significant drop in the refrigeration effect, contact a professional immediately to check for refrigerant leaks.
l Keep the outdoor unit area clean and free of debris to prevent it from affecting heat dissipation.
Regular maintenance is crucial, especially before and after the rainy season.
During and after the rainy season, it is recommended to schedule a comprehensive maintenance check to ensure equipment is in good working condition. Maintenance services include:
l Clean condensers and heat sinks to prevent dust blockages.
l Inspect electrical connections and wiring insulation.
l Monitor critical parameters such as refrigerant pressure and operating current.
l Add a protective cover to the outdoor unit to prevent rain and dust, while ensuring good ventilation.
Establish emergency response plans to enhance efficiency.
For large commercial complexes, office buildings, hospitals, and similar venues, it is recommended to proactively formulate an emergency response plan for air conditioning operation during heavy rainstorms, including:
l Identify responsible parties and assign dedicated personnel to inspect high-risk areas.
l Establish a rapid response mechanism with maintenance units.
l Prepare emergency spares, such as electrical control panels, drainage pumps, etc.
l In the event of an abnormal situation, shut down immediately and report for handling.
