The “Dry” mode of air conditioners, often overlooked, is nevertheless a valuable ally for optimal comfort.
That’s it, it’s summer and with it its share of new questions. One comes up often: how does this air conditioner work and how to use it properly? Before turning it on, and while using it responsibly both for your wallet and for the planet, it is essential to understand all the functionalities of these devices to get the most out of them.
Some modes are not well known. Logos, numerous buttons, terms in English… Not always easy to see clearly, especially if you have lost the instructions or if you are not at home, in a hotel or on vacation and we are not used to using these devices at home. Among these functions, the “Dry” mode, also sometimes symbolized by a drop of water, often remains a mystery. However, it can be very useful in certain situations.
The “Dry” mode is not intended to further cool the room. Its main role is in fact to reduce ambient humidity, without drastically dropping the temperature. It should therefore not be confused with the “Cool” mode, represented by a snowflake, which aims to cool the air but is much more energy intensive. “Dry” mode can therefore be a good idea, both for your comfort and for your budget.
In “Dry” mode, the air conditioner draws moisture-laden air from the room. This air then passes over the cold evaporator where the humidity condenses into water, evacuated to the outside. The air, now less humid, is slightly warmed before being redistributed throughout the room. The compressor also runs at a slower rate than in “Cool” mode, which saves energy.
But when should you use this famous “Dry” mode? It is particularly suitable during humid and muggy days, where the air is full of humidity without the temperatures being scorching. It’s also a good choice during transitional seasons like spring or fall, where humidity can be high without excessive heat.
If the air in your home seems stuffy or difficult to breathe due to humidity, this mode can also provide real comfort by making the atmosphere cooler and less humid. In winter, it is also a good way to protect your interior from excessive humidity which can encourage the appearance of mold. In regions with a tropical or coastal climate, where humidity is a recurring problem throughout the year, the “Dry” mode can be used regularly, especially at night.
“Dry” mode is therefore an excellent choice if the room is humid but not excessively hot, or if you want to avoid too dry air. On the other hand, if your main objective is to cool the room, especially during the hottest days of summer, it is better to opt for the “Cool” mode. Likewise, during heatwaves and without a storm on the horizon or heavy air, the “Dry” mode will really be worth forgetting!
