Will A Dehumidifier Cool A Room?

Millions of people use dehumidifiers and many of them often have a query of “will a dehumidifier cool a room.” Well, yes they can cool a room but they aren’t meant to do it. So, keep on reading to find a detailed answer to your query of will a dehumidifier cool a room. 

When it gets hot and humid, we try to cool ourselves by turning on the air conditioner. However, air conditioners consume a lot of power and cause high electric bills. To save energy, you may wonder if there’s a possibility your dehumidifier will cool a room so that you won’t have to use the AC. Seems like a good, energy-saving option, right?

There are many benefits of dehumidifiers. And there’s no denying the fact that dehumidifiers do help in making a room more comfortable and even cool the space, but they are not meant for this job. Cooling the room is a job well-suited for the AC while a dehumidifier’s task is to control humidity.

Does a Humidifier Play a Role in Cooling a Room?

When the humidity level is high, have you felt that the air is warmer than the actual temperature? Well, it is true and that’s why a dehumidifier can help in cooling a room as it sucks in humid air and removes excess moisture from it. The moisture in the air is then condensed in the dehumidifier and collected in an external bucket. 

You may have heard or read that dry heat is much easier to handle than the heat when the humidity levels are high. It is true because your body isn’t able to cool itself properly whenever humidity is high. 

Your body regulates temperature by sweating and the body feels cooler when the sweat evaporates from the surface of the skin. But when the humidity levels are high, the sweat doesn’t evaporate so quickly and that’s why the temperature feels more than what it should be e.g. 30 degrees Celsius will feel more like 40 degrees Celsius if the humidity level is high.

So, the answer to the question of “will a dehumidifier cool a room?” is  yes, it does help. After all, less humidity will feel cooler than more humidity.

When it is humid, you will notice that the air is denser and there’s a damp feeling that makes it difficult for you to breathe. A dehumidifier runs the dense air through it and extracts water vapors to reduce density. Hence, it makes the room feel more comfortable and cooler.

How A Dehumidifier Helps Air Conditioning?

As opposed to running a dehumidifier and expecting it to cool your room, it is best to make it help the air conditioning work more efficiently. You can use a dehumidifier to control the humidity in the air and when it is done extracting excessive moisture from the air, you can turn on the air conditioner. This way it will be much easier for the AC to cool air in the room that is already dry. 

In case you don’t use a dehumidifier, then the AC would have to work harder to make the dampness go away and make the room cool.  Even using a dehumidifier will help in saving energy as you won’t need to use the AC for many hours. Also, using a dehumidifier in the room puts less strain on the AC to do the entire job, which avoids untimely wear and tear.

Using A Dehumidifier The Right Way

If you live in an area where there’s a lot of humidity then it would be best to run a dehumidifier for most of the day to keep the home cool. Experts recommend using a dehumidifier in areas where it is hot and humidity levels are high. 

By using a dehumidifier, you can keep your home environment comfortable. Other benefits of using a dehumidifier are that it enhances air quality inside the house and makes the environment inhabitable for dust mites. It also prevents the growth of mold by removing moisture from the air and makes the temperature feel inside the house cooler.

If you live in a climate that is hot for most of the year but does not have a lot of humidity, then running a dehumidifier all day long is not recommended. It is because a dehumidifier will generate heat if you run it for many hours. 

So, if you live in an area that doesn’t have a lot of humidity then it would be best to run only the air conditioner to save energy costs. Still, if you want to buy a dehumidifier then you should consider the smaller portable ones that are best for a single room and not the whole house.

Alternate Ways for You To Cool A Room

Many homeowners have a query of “will a dehumidifier cool a room,” but they often seem to neglect some pretty good alternative ways to cool a room. If you don’t want to use a dehumidifier or an air conditioner to cool the space, you can always consider other ways. 

For instance, using a ceiling fan is a good option to cool a room. As hot and humid air heavier, it stays around objects and people in the room. A ceiling fan can help blow the air around and make it easier for the body to release its heat. Using a ceiling fan can certainly make the room feel a few degrees cooler.      

There is another method to quickly cool the room. You can use a fan and a large bucket containing ice. Put the bucket in front of the fan and you have yourself a mini-ac that will blow cool air.
