When you use an air conditioner in high fan-only mode, the unit operates without engaging the compressor. In this mode, the air conditioner's fan runs at its highest speed, but the cooling function is turned off. Here's what happens when you use an air conditioner on high fan-only mode:
Air Circulation: The primary purpose of using the fan-only mode is to circulate air inside the room. The fan pulls air from the room, passes it through the air filter to remove dust and particles, and then pushes the filtered air back into the room. This helps improve air circulation and can reduce stuffiness.
Ventilation: If the air outside is cooler than the indoor temperature, running the fan-only mode can help bring in fresh air from outside, potentially improving ventilation. However, keep in mind that this will not cool the room, as the cooling function is disabled in fan-only mode.
No Cooling: It's important to understand that using the air conditioner in high fan-only mode does not provide any cooling effect on its own. The absence of compressor operation means that the air conditioner is not actively removing heat from the indoor air, and therefore, the temperature of the room will not decrease.
Energy Efficiency: Running the air conditioner in high fan-only mode is more energy-efficient compared to running it in cooling mode. The compressor is the component that consumes the most electricity in an air conditioner, and when it is not running, the energy consumption is significantly lower.
White Noise: Some people find the sound of the fan running in fan-only mode to be soothing and comforting, similar to white noise. This can be helpful for relaxation or sleeping.
Overall, using an air conditioner in high fan-only mode is beneficial for air circulation and ventilation, and it consumes less energy than running the compressor in cooling mode. However, it's essential to recognize that it will not provide cooling, and if you desire a cooler indoor environment, you'll need to use the air conditioner in its regular cooling mode, which engages both the fan and the compressor.
