Aircon Dry Mode: Facts And Functions

What is Dry Mode in your aircon unit?

It is the function which is used during the rainy days as during rainy days moisture level is very high and this mode keeps the room atmosphere cool and dry by making the air dry.  Dry air mode also refreshes the air in humid climates.

Dry mode simply works by sucking out the moisture of the air or humidity so that the air becomes bearable and comfortable since the humid air is taken into the air conditioner, dried by the evaporator, and then released back into the room as dry air. In this mode, the air conditioner does not blow plenty of cool air, but rather it dries the air.

The Importance of Dry Mode

Dry mode is especially important for energy efficiency, as knowledge of dry mode will allow you to use it in the appropriate weather. You shouldn’t be using the standard “cool mode” all the time, as this isn’t energy efficient. It is important to note that it does not work as an air dehumidifier as it does not suck all the moisture from the room, rather maintains the room comfort at least at 60% humidity.

What are the main benefits of using Dry Mode especially during hot summer days? 

1) Aircon dry mode means a healthy home and a healthy family

It has always been a fact that dehumidification keeps indoor air at its optimum humidity level, which helps you and your family breathe easier. But that’s not all, as it also fights against common allergy triggers, such as dust mites, mold, and mildew which thrive in an excessively humid environment.

Another downside of living in a high humidity climate is that, over time, excessive moisture can potentially develop mold on your clothing, furniture, bed linen, towels, or curtains. It can also cause minor or serious damage such as rust or corrosion to your electronic devices or home appliances. Dehumidification proves to be a very effective tool to protect your property, from the very basic to your most valuable possessions.

2) Dry mode means odor-free air

Besides cleaning the air, dehumidification can eliminate the odors that can accompany mold, damp or mildew in your home. You won’t have to worry about that annoying “musty” smell anymore when having friends over, as the air stays fresh and welcoming.

3) It can lower your energy costs

During the hot summer days, keeping your energy costs at a reasonable level can be a major concern. Since it’s not all about the heat but also the humidity, you don’t have to lower the temperature that much but leave the “dry mode” in charge instead.

Because your air conditioner’s compressor runs at a slower pace, it will use less energy, which eventually means less money on the monthly bill.

4) Dry mode helps improve your home’s overall comfort level

If you feel clammy, sweaty, or tired because of the high humidity levels, the “dry mode” will be your friend in need without dramatically lowering the thermostat settings on your air conditioner.

Other important facts to know about the aircon Dry Mode: 

What is the best temperature for Dry Mode?

Assuming that the aircon thermostat is set to 25°C and that the moisture level in the room is about 90 percent, the aircon unit will decrease moisture until the temperature is 25°C in that room. When the aircon is turned on, the fan fills working to suck in the air as well as the compressor cuts in to make the condensation of the moisture.

Once the space temp has dropped to 25°C then both compressors and fans will stop. Moisture rises slowly once again and so does the temp. When the temp goes to 26°C, the system starts running once again the cycle repeats itself. Therefore, the best temperature for dry mode is 25°C

When to use Dry Mode? 

1) Use the dry mode option of your aircon unit when the temperature is normal and the humidity is not too extreme. The dry mode can also be used to reduce the temperatures and make your room more comfortable when it is hot. However, the main purpose of the dry mode option is to remove excess water from the air and lower the humidity level but may provide more benefits when they are used in the right way.

You can use the mode when you don’t need cool air as well. Sometimes, comfort might be lowered simply because of humidity, this usually occurs when your city is located close to the sea and may occur during monsoons as well. However, during those days, using dry mode may provide you with a lot of comfort.

2) Another time to use a dry setting on your aircon unit is when you have allergy sufferers at home. The aircon unit dry mode can help you to maintain an optimum humidity environment, which in return helps both you and your family to breathe easily. Not only that, but it can also prevent several allergy triggers like mold, dust mites, and others associated with an excess humid environment.

3) You can also use a dry setting on your aircon when you want to avoid damages associated with a high humidity environment. When there’s extra moisture, it may promote the growth of mold on used furniture, clothing, and others. However, it may even result in small or severe damages like corrosion or rust on your home appliances.

Can I use Dry Mode all day? 

HVAC professionals recommend only using the aircon dry mode for 1-2 hours, at most. While the “Dry Mode” does a good job in lowering air moisture, keep in mind that it shouldn’t be used to completely remove the humidity of the room. It should only be used to maintain humidity at a level that is ideal for human comfort.
