The cooling motor for the inverter type air conditioner will reduce or increase the number of rotations for the motor depending on the difference between the indoor temperature and the target temperature.
If the indoor temperature is high and thus cooling is required, then the number of rotations for the cooling motor is increased for higher cooling performance, thus noises can be louder.
And, as the indoor temperature gets close to the target temperature, the number of rotations for the cooling motor is reduced and the noises will be also reduced.
