Warning Signs of Air Conditioner Overload
Warning signs of air conditioner overload include poor cooling performance, slower than usual, and automatic shutdown of the system when the outside temperature rises significantly.
If your air conditioner exhibits one of the two warning signs mentioned above, it could be operating under overload conditions.
Why Does Air Conditioning Overload Occur During Hot Days?
There are several reasons why air conditioners – air conditioners are overloaded in hot seasons, among which the main causes are:
+ Installing air conditioners with smaller capacity than the room area makes the air conditioner have to operate continuously, leading to overload. Therefore, the device will automatically shut off or stop working to ensure safety.
+ Continuous 24/7 operation of the air conditioner prevents it from resting, forcing it to operate 24/7, leading to overload of the outdoor unit operating continuously to generate more heat than usual. Combined with the outdoor temperature in hot weather always staying at a high level, it is very easy to lead to the risk of explosion.
+ Setting a low temperature: Wanting the room to cool quickly, many people have a habit of setting the temperature below 23 degrees Celsius. However, setting the temperature too low can overload the system because it operates at maximum capacity. Not only causing overload, setting the temperature too low can also cause heat shock or sudden death if you step out suddenly from the air-conditioned room to the hot outside.
+ Dirty air conditioner: Air conditioners that have been used for a long time but are not cleaned accumulate dust and adhere to the fan blades as well as the internal components of the machine. If not cleaned, it will greatly affect the cooling efficiency of the air conditioner, causing the machine to run continuously to cool the room, leading to overload.
Is an overloaded air conditioner dangerous?
Air conditioner overload can potentially damage internal components and even result in dangerous explosion incidents. Specifically:
+ Damage to machine parts: Running the air conditioner overloaded for a long time can lead to malfunctions of internal components such as capacitors, compressors, etc.
+ Dangerous explosion incidents: When the air conditioning system is overloaded, it can lead to extremely dangerous explosion incidents such as explosion of the evaporator coil, explosion of the condenser coil, explosion of the electrical wiring...
Solutions to Overcome and Prevent Air Conditioner Overload
To overcome and prevent air conditioner overload during hot summer days, when using the air conditioner, you should:
+ Regularly clean and maintain the air conditioner every 3 - 6 months depending on the frequency of use.
Limit obstacles in front of the air outlet of the air conditioner.
Avoid running the air conditioner 24/7; switch it off after 6-8 hours of usage to allow the air conditioner to rest.
Set the air conditioner at a reasonable temperature, preferably no lower than 25 degrees Celsius or just 8-10 degrees Celsius below the outdoor temperature.
Regularly clean the filter at the indoor unit of the air conditioner to help remove accumulated dust and dirt.
Choose an air conditioner with an appropriate capacity for the room size. For example, a 1HP – 9000BTU air conditioner is suitable for rooms under 15m²; a 1.5HP – 12000BTU unit is suitable for rooms from 15-20m²; a 2HP – 18000BTU air conditioner is suitable for rooms 20-30m²...
Above are the details regarding the issue of air conditioner overload during hot summer days. Hopefully, they will be useful for you in using the air conditioner!
