General instructions for operating the air conditioner
And correct.
That the air conditioner in both cases operates with the same power, that is, in both cases, the same cold will be produced.
To be more clear, when you set the device at a temperature of 17, the room will not cool down faster if the air conditioner is set at a temperature of 24 or other because the capacity of the air conditioner Fixed.
When the outside temperature is 40 (for example) and the air conditioner is set to 24 degrees, the air conditioner motor (compressor) will run until the room temperature reaches 24 degrees, and then the motor is disconnected and rests, and it will work again when the room temperature rises again.
But when it is set at a low temperature of 17 or 18, and the temperature outside is close to or above 40 degrees, your setting of the device is wrong and illogical, as the device will not be able to reach the room to 17 or 18 degrees Celsius and the air conditioner engine will remain in a state of permanent operation for hours This will affect its efficiency and life, not to mention excessive energy consumption.
