■ Title
- The noise from the outdoor unit keeps increasing and decreasing.
■ Problem
- Noise/Vibration
■ Possible Cause
- The inverter outdoor units can increase or decrease the cooling capacity according to the room temperature by controlling the rotating speed of the compressor.
If the room temperature is high and requires high cooling capacity, it increases the rotating speed of the compressor (↑Noise),
And when the room temperature drops down, it requires less cooling capacity so the inverter reduces the rotating speed of the compressor(↓Noise)
■ Solution or Settings
▶ Noise occurring phenomenon
- It’s easy to explain using the car speed as an example.
It is the same case as when the speed of a car increases, the sound of engine increases, and the engine sound decreases when its speed is reduced.
▶ The rotating speed of the compressor and its noise by room temperature
■ Summary
- The inverter outdoor units can increase or decrease the cooling capacity according to the room temperature by controlling the rotating speed of the compressor.
If the room temperature is high and requires high cooling capacity, it increases the rotating speed of the compressor (↑Noise),
And when the room temperature drops down, it requires less cooling capacity so the inverter reduces the rotating speed of the compressor(↓Noise)
