Best temperature for dry mode in AC ( 25°C and why )

Struggling to choose the best temperature for dry mode or how to adjust dry mode temperature setting?

You come to the right place. Before we show you the best dry mode temperature setting, we would like to share how ac dry mode work ( also known as ac humidity mode or aircon dehumidifier mode or dry setting on ac or aircon dry mode )

What is dry mode in ac?

What is the dry setting on an air conditioner for? What does dry mode do in ac? People always compare aircon dry mode to aircon cool mode. To be honest, they do not feel practically different. Though they’re unique in feature, as the remote will hint at you, the dry mode symbol in ac is normally represented by a water drop in the remote control while the cool feature mode is normally presented by a snowflake.

AC dry mode is not a very common function but is found in some sorts of certain AC units. What does the dry function on air conditioner do?

Dry function on air conditioner is to decrease the humidity in the room. As you might know, living here in Singapore city, humidity forever translates to a boost in temp. Even at low temps, humidity level tends to be rough.

The dry setting on ac will lower the humidity level and is most convenient during periods in the year when it is extremely humid – like during the rainy periods, for instance.

During this period, the temp might not be warm enough to necessitate having your Air conditioner at the complete blast, but the humidity level will feel irritating and uncomfortable. This is an ideal time to turn on dry mode in ac. Although it would not remove entire moisture in the home, it’ll surely make it more manageable for the residents to be in.

How does dry mode in ac work? What does the dry mode do on an air conditioner?

When dry setting on an air conditioner turn on, the fan and other components of the machine will be running, though, the unit doesn’t blow out any cool air. The air in the home passes via the AC and the water vapor compress on the evaporator. Now dry airflow will then depart the system and airflow back into the area.

This process of the feature is almost the same as that of a de-moisturizer. A separate dehumidifier can be set up at just about hardware store or house enhancement. This one is superior to the AC working on in this feature in the case that you’re working in a big room. The AC will only eliminate some of the humidity and not the entire.

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

Once the space temp has dropped to 25°C then both compressors and fan will stop. Moisture rises slowly once again and so does the temp. When the temp hoes to 26°C, the system starts running once again the cycle repeats itself.

What temperature should dry mode be set at? The best temperature for dry mode is 25°C

However, depending on the humidity level, the temperature of your home, and the season of the year may allow each mode of your air con to save energy and runs with peak performance.

Furthermore, the good news is that when you understand how each setting works and when to use them, you can use your air con more productively rather than using full blast always, which can make you uncomfortable sometimes.

Use the dry mode temperature setting 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.

Dry mode is a particular function of a machine while the dehumidifying the only function of a dehumidifier. Although the dry mode cannot completely replace a dehumidifier, it can serve an alternative within a limited scope.

However, weather is unpredictable nowadays getting a dehumidifier may not always guarantee the comfort you are seeking. Although dehumidifiers tend to use less electricity during operation but don’t forget dry mode is just a particular function on the air conditioner, which you may use when the temperature is acceptable and the humidity level is high.

Moreover, dry mode power consumption is less compared to a dehumidifier machine, which may completely dehumidifiers your room but results in much power consumption. Also, an air conditioner can provide more comfort when the temperature is high and the humidity level is normal.

Dehumidifier, on the other hand, makes the room temperature more comfortable to live in while lowering the level of humidity in a room.

As stated earlier, dehumidifiers are specifically designed to remove excess moisture and more efficient when there is much moisture in the air. But when the air is very hot and the humidity level is moderate, an air conditioner may be much more effective.

In short, the air conditioner can effectively manage indoor heat as well as humidity. Besides, the air conditioner is now popular and widely affordable. We have an in-depth article on dry mode vs dehumidifier. Please kindly have a look if interested.
