In the "Dry Mode" of an air conditioner, the primary purpose is to reduce indoor humidity rather than providing maximum cooling. It is also known as the dehumidification mode. When you activate the Dry Mode, the AC's compressor and fan operate at lower speeds compared to the regular cooling mode.
Here's how the Dry Mode works:
Reduced compressor speed: The compressor is responsible for compressing the refrigerant, and it plays a crucial role in cooling the air. In Dry Mode, the compressor's speed is reduced, which means it runs for shorter cycles and doesn't operate at full capacity. The reduced compressor speed helps in extracting moisture from the indoor air without lowering the temperature significantly.
Longer run time: The AC will run for more extended periods in Dry Mode compared to the regular cooling mode. This extended runtime allows the air conditioner to maintain a lower humidity level by continuously removing moisture from the air.
Comfortable humidity levels: The Dry Mode is especially useful in humid climates or during the rainy season when the air feels damp. By reducing indoor humidity, the air becomes more comfortable, even if the temperature remains relatively constant.
Now, if you set the temperature to the lowest level while in Dry Mode, it may have little to no effect on the cooling capacity of the AC. The primary focus of the Dry Mode is dehumidification, not extreme cooling. Even if you set the temperature to the lowest level, the compressor will continue to operate at a reduced speed, and the AC's cooling effect will remain limited.
If your goal is to achieve maximum cooling, you should use the regular cooling mode (usually denoted by a snowflake symbol). In this mode, the compressor and fan operate at their full capacity to achieve the desired temperature quickly. The cooling effect will be much more noticeable compared to the Dry Mode.
In summary, the Dry Mode of an AC reduces the compressor's speed to focus on dehumidification rather than maximum cooling. Setting the temperature to the lowest level while in Dry Mode won't significantly increase the cooling effect because the primary function of Dry Mode is to maintain comfortable humidity levels rather than providing extreme cooling. If you need strong cooling, it's best to use the regular cooling mode of your air conditioner.
