I recorded the running sound of a Toshiba air conditioner outdoor unit, RAS-H406ADRH, during heating and cooling.
The compressor is equipped with Toshiba's unique, variable-cylinder twin rotary compressor, commonly known as a dual compressor or energy-saving compressor, which switches to one-cylinder operation at low loads and thus changes to a single-like atmosphere despite the twin rotary This is a unique feature of this compressor.
In addition, when operating at low speeds, a sound that seems to originate from the motor can be heard relatively well, and together with the sound of the mechanical parts in operation, it has a pleasant tone.
Please enjoy the sound of operation by the slow control of the Toshiba original, which has become rare nowadays.
0:00~ Heating running sound

○Cylinder number switch point

　10:45 , 46:40

※Because it was recorded indoors, it was not operated up to the maximum RPM.
