Typhoon Approaches; How the Storm's猛烈的暴风雨Endangers Lives and Threatens Large Central Air Conditioning Systems"Disposal Alert": A flipped outdoor unit, reversed motor burnout, waterlogged and short-circuited electrical control panel...One oversight could result in tens of thousands in losses or even safety accidents. Don't wait until your air conditioner "goes on strike" to regret it—these crucial precautions for using central air conditioning during typhoons, you must know now!
When operating large central air conditioning systems during typhoons, it indeed requires extra caution. Here isSixKey Precautions to Be Aware of and Act Upon in Advance:
Prior to and after the typhoon's landing, it is recommended to suspend the use of air conditioning.
Strong winds may cause the outdoor AC fan to reverse, impacting the motor and wind force."Confrontation" can easily lead to motor damage and even overheating fires.
If the outdoor unit is facing the direction of the incoming typhoon (e.g., if the typhoon is coming from the east and the outdoor unit is on the east wall), the risk is higher, and the air conditioner should be turned off immediately.
Prevent lightning strikes and short circuits by shutting off power early.
Typhoons often come with thunderstorms, which may cause transient power surges in the power grid. It is recommended to turn off air conditioners and disconnect power sources to prevent damage to electrical panels or potential fires.
If the outdoor unit is submerged in water, it is strictly prohibited to power on. It must be inspected by a professional before it can be used again.
Ensure outdoor unit installation is secure
Ensure that outdoor unit brackets are checked for rust and bolts are tightened before the typhoon to prevent the unit from falling during strong winds.
Recommend adding anti-fall chains or triangular support frames to enhance wind resistance.
4. Prevent external machines from being struck by debris or from water intrusion
Outer Machine SurroundingsItems such as flower pots and billboards that can be blown away should be cleared within 1-2 meters.
Protective covers or condenser grille options are available to prevent rain, branches, and sand from entering the outdoor unit.
Post-tropical storm, inspect before powering on
After the typhoon, do not turn on the air conditioner immediately. First, check if the outdoor unit is damaged, if the wiring is wet, and if the brackets are deformed.
At first boot, it is recommended to set to the cooling mode.Monitor for smooth operation and any unusual noises between 24-26°C.
6. Large venues should activate emergency response plans.
Commercial complexes and office buildings should develop typhoon air conditioning emergency plans in advance, including:
Identify responsible parties for inspections in high-risk areas.
Prepare emergency spares (such as control panels, drainage pumps).
Establish a rapid response mechanism with the maintenance and service unit.
Special Reminder:
If the air conditioner has been submerged in water, do NOT turn it on! Only for professional maintenance.
Do not attempt to repair or inspect the exterior machinery yourself; checking it out during a typhoon is highly prone to accidents.
For large central air conditioning systems, it is recommended to schedule a comprehensive maintenance check before and after the rainy season, including cleaning the condenser, inspecting the electrical circuits, and testing the refrigerant pressure.
