When an air conditioner says "cool," it typically refers to the cooling mode of operation. Air conditioners have different operating modes, including cool, heat, fan, and sometimes additional modes like dehumidify or auto.
In the cool mode, the air conditioner will lower the temperature of the room by extracting heat from the indoor air and releasing it outside. It does this by circulating refrigerant through a cycle of compression and expansion, absorbing heat from the indoor air and expelling it outside. The cool mode is used to lower the temperature and provide a comfortable indoor environment during hot weather.
When you select the "cool" mode on your air conditioner, it will start cooling the room by blowing out cold air. You can typically adjust the temperature settings, fan speed, and other features based on your comfort preferences.
It's important to note that different air conditioner models may use slightly different terminology for their operating modes. However, the "cool" mode is a common and widely used term to indicate the cooling function of an air conditioner.
