What is the Dry Mode in Air Conditioners: A Rundown

 In Blog, Residential Air Conditioner System, Tips

Have you ever used the dry mode function on your air conditioner? Do you always have your air conditioner on the same mode? Do you even know what all of the different modes are for?

When it comes to feeling comfortable in your indoor space – whether it’s your office building or home, there are more to it than just temperature. Humidity also plays a very big role. High humidity can cause you to struggle to breathe properly and to shift uncomfortably in your chair.

Let’s take a closer look at humidity and why trying that dry mode on your air conditioner might just be the best idea yet – provided that you use it in the right weather conditions.

We break down what the dry mode in your air conditioner really means, what it is supposed to help for, as well as when and how to use it.

A Rundown of What Your Air Conditioner’s Dry Mode Means

What is Dry Mode?

Why would you use dry mode? Well, in short, you will use it on those rainy, humid days when the moisture level is high, but the temperature is not so hot. It’s for when you would like to keep the room comfortably cool but at the same time also dry.  So, it effectively acts as a dehumidifier by sucking out the moisture in the air, refreshing the air you are inhaling.

It’s important to control the humidity indoors as it can cause mould to grow indoors, which can be a dangerous pollutant and cause for poor indoor air quality, causing a host of health issues.

Tropic Like It’s Hot: When Would I Use the Dry Mode Setting on My Air Conditioner?   

Think of the last time you experienced tropical weather – it’s for that exact climate that you would use the dry mode setting on your air conditioner. In short, if your home or office is not that cold and not that warm but very humid and sticky you might want to consider switching to dry mode.

What Is Dry Mode Supposed to Help For?

It dehumidifies the air in the room you’re in. It’s only effective in cooler weather so don’t try to use it when it’s a boiling hot summer’s day. On those days, you should rather opt for the cooling mode setting on your air conditioner.

If you are looking at switching to dry mode in your car, it is ideal for when you want to defog your windscreens internally. Another nifty function is that it will dry you off quickly after you had to dash through the rain to get to your car.

When and How to Use Your Air Conditioner’s Dry Mode

It’s important to understand that, just as the temperature changes from season to season, the humidity also changes. And just like you have to switch between heating and cooling depending on the season, you also have to consider the different modes on your air conditioner that can help regulate the humidity in the air.

So, the purpose of that dry mode function on your air conditioner is to simply act as a way to soak up all the excess moisture or humidity in the air – on a large-scale basis.

What happens when you switch on this function? The fan inside of your air conditioner will still run. It just won’t be blowing any cool air. That way, the air passes through the system so that the vapor can condense in the evaporator, recirculating the dry air back into the room.

Is Dry Mode More Economical?

In short, yes. It’s important to know which function you are using when not only to optimise the effect it will have on the temperature and humidity, but also for energy efficiency.

No one should use the cool mode every day simply because that’s all they know. There’s a reason why there are other options! The weather is never the same every day, so why should your air conditioner mode be?

If you use the dry mode in the correct humid but not-too-warm environments, it will be more energy efficient and reduce your overall electricity bill at the end of the month.

What is the Difference Between Cool and Dry Mode?

Upon closer inspection, you will see that the dry function on your air conditioner has a water drop symbol on it, so it is very apparent what it’s for. The cool mode, which is indicated by a snowflake icon, is very apparent as well. The first one dehumidifies, the latter cools – it’s even in the name!

When your air conditioner is set to cool mode – you guessed it – cool air will flow into the room. But if your air conditioner is set to dry mode – you guessed it again – dry air will circulate back into the room. They both work in similar ways, dry mode just doesn’t actively cool down the room and simply uses the fan and condenser system to suck the moisture from the air.

A word of warning, however, do not leave your air conditioner on dry mode. It should only regulate your room’s humidity, not remove the humidity entirely.

Can I Use Dry Mode in Winter?

Well, it depends but yes. In Perth, our winters are wet but cold, so you won’t necessarily use this function. Remember that humid plus warm, comfortable weather equals dry mode. However, if you are heating up your space indoors while it is pouring outside, the humidity can rise, causing you to consider hitting that dry mode button to regulate things to a comfortable level.
