Dry Mode for air conditioning and how to use it properly….

An air conditioner has become a vital home item due to the heat waves we have been experiencing in Queensland on the Sunshine Coast. Though many homeowners have an AC unit, very few people actually know about the variety of features that come with your air conditioner. For instance—do you know what the aircon dry mode is and what it’s for?

It’s understandable that you may not be aware of your aircon’s full features. After all, time is a precious commodity, and who has the time to read a manual? On the flip side though, air conditioners are an investment and a monthly expense when you consider its impact on your electricity bill. Understanding its full features will help you understand its processes better and will help you regulate your aircon usage.

Depending on the time of year, the temperature and humidity levels change, and you can save energy by switching the mode that your air conditioner is running on. With a simple understanding of each setting, you’ll be able to make the most out of your air conditioner while keeping the cost at minimum, rather than just cranking up the air conditioning to full blast every time you get uncomfortable.

Yes, it can be a little bit overwhelming. Air conditioners come with multiple options. There are cool, dry, and fan options. Some units have “economic cool” and “powerful cool,” too. There are time settings and modes and a host of other things to take note of. But not to worry! We’ve written this article to help familiarize you with one of the most useful and important modes of your air conditioner: the aircon dry mode.

What is the Dry Function Mode?

Dry mode is often compared to or confused with the cool mode. To be frank, they don’t feel particularly different. However, they are distinctive in terms of function, as the remote control will hint at you: the dry mode is usually represented by a water drop while the cool mode is usually represented by a snowflake.

The aircon dry mode isn’t a very common feature, but is found in all Daikin air conditioning units. The main point of the dry mode is to reduce the humidity in the room. As you may know, living in Queensland, humidity always translates to an increase in temperature. Even at low temperatures, humidity tends to be uncomfortable.

The dry function will lower the humidity, and is most convenient during times in the year when it’s very humid—like during the rainy season, for example. During this season, the temperature might not be hot enough to necessitate having your aircon at full blast, but the humidity will feel uncomfortable and irritating. This is the perfect time to utilize dry mode. Though dry mode won’t remove ALL moisture in the room, it will definitely make it more bearable for the occupants to be in.

How Does Dry Mode Work?

The dry mode of an AC unit works like a large-scale dehumidifier. When the air conditioner is functioning on aircon dry mode, the fan and the other inner components of the unit will be running, but it won’t blow out any cold air. Rather, the air in the room will just pass through the aircon and the water vapor will condense in the evaporator, removing moisture from the air. The now-dry air will then exit the unit and flow back into the room.

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. “Cool mode” should be used during hot and dry seasons, while the aircon “dry mode” is more appropriate for humid seasons that aren’t necessary hot and warm in temperature.

Utilizing dry mode more often is also better for the environment. By using dry mode when appropriate, you’re also reducing energy costs via energy efficiency, and overall lowering your carbon footprint.

The Difference Between Dry Mode and Cool Mode

As mentioned previously, dry mode takes care of the humidity levels in the room, and is usually distinguished in settings with a water drop symbol. On the other hand, cool mode  is the standard mode of air conditioners, cooling the room by removing heat—not moisture—from the air. This mode is usually marked by a snowflake on your aircon settings.

In your aircon dry mode, the air conditioner isn’t really releasing cold air, and isn’t actively cooling the room. While it may not feel different than your aircon’s cool mode, the cool air you’re experiencing in Dry mode is just dehumidified air. This effect is better felt in a room where the humidity levels are 90% or more—aka a hot summer day on the Sunshine Coast or RIGHT NOW with all this rain!

Internally, cool mode and dry mode also work similarly. The only difference is that in aircon dry mode, all the internal components are running but not circulating coolant to cool the air. In aircon dry mode, the air from your room just passes through your AC unit to remove the heat and moisture.

Now, while the aircon dry mode lowers air moisture, it doesn’t remove humidity from the room 100%. It only maintains humidity at a level best for human comfort, as dry air in excess is just about as uncomfortable as an extremely humid room. AC 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. After all, dry air in excess levels is just about as uncomfortable as an extremely humid room. This is why most experts suggest that the air conditioner should only run in “Dry Mode” for 1-2 hours, at most.

In short: dry mode doesn’t really cool the room, and the “cooling effect” comes from the removal of excess moisture from the air. Cool mode is the regular mode of most air conditioners and does not decrease the humidity in the air, but the temperature of the room. Some benefits of aircon dry mode include:

  • Greatly dehumidifying the room
  • Energy-saving
  • Cost-effective

When Should You Use the Aircon Dry Mode?

Use Dry Mode When:

  • The temperature is cool, but the humidity is high (such as a humid rainy day, perhaps)
  • You need to conserve electricity
  • You don’t want the air of the room to be too chilly
  • It’s the cooler months of the year, such as in June or in August

Use Cool Mode When:

  • Both the temperature and the humidity levels are excessively high
  • You want the room to stay at a consistently cool temperature
