Does a dehumidifier cool a room?

Will a dehumidifier make the room cooler?

3 Key Takeaways:

πŸš€ Technically, a dehumidifier cannot cool a room. The one that can do that for you is an air conditioner.

πŸš€ Dehumidifiers are designed to remove humidity and leave you with dry air. They can improve your indoor air quality, but they don’t operate like air conditioning units and won’t reduce the room’s temperature.

πŸš€ Dehumidifiers work by drawing air in, removing the water vapor, and then releasing it back into a room. The moisture gathers in a tank so it can be emptied afterward.

 Having a home that is constantly brimming with coolness and comfort is the dream of every homeowner. Most of the time we go out of the way to keep our home cool and comfortable. But the question here is, does a dehumidifier cool a room? Can a dehumidifier truly alter the room temperature and make it cool? The answer is NO.

Technically, a dehumidifier cannot cool a room. The one that can do that for you is an air conditioner. Dehumidifiers on the other hand can only make your environment more breathable and fresh by altering the humidity levels. It might seem like the air feels cool when a dehumidifier is on in a room, but it really does not and cannot do that. Keep reading to know more about the exact function of dehumidifiers and the role they play when it comes to room temperature in the space they cover.

Can I use a dehumidifier instead of an air conditioner?

Can dehumidifiers be used instead of ACs, the answer to this is, again a NO. In reality, a dehumidifier device is only capable of altering the high humidity level in the air. It does not send out cool air. It is not a replacement for air conditioning units. However, surprisingly it does feel like the air is cool when you have a dehumidifier running in any part of the room. To realize why you find this alteration in temperature, you must first understand how does a dehumidifier work.

Here is everything a dehumidifier does for your home…

High humidity is when the air is laden with moisture. Excess moisture in the air increases the relative humidity levels. Humid air is uncomfortable to be in; it is heavy, it does not facilitate sweating in your body, it makes one feel hot with very little room to feel better, you might be under the impression that there is warm air around you that is leaving you suffocated. Excess water in the air promotes the growth of mold and mildew. In addition to this, all rooms of your home might be damp and wet, causing plentiful damage to health and property. High levels of humidity can cause difficulty in breathing and problems related to the lungs. Increased humidity can hinder the seamless functioning of other appliances as well.

Is this the story of your home? If yes, this is where you can use a dehumidifier to make things better. Dehumidifiers remove moisture from the air. They are designed to alter and reduce the relative humidity in your room. Dehumidifiers remove this excess water vapor and store it within their storage unit. This water can be emptied out. There is a difference in how every dehumidifier model works. You can always pick out the dehumidifier that best suits the need of your home.

For example, there are models that have the option of adjusting the humidity, setting a timer or alarm when it’s time for the tank to be emptied, energy-saver designs, the difference is the material of coils, silent operation dehumidifiers, amount of area covered, etc. Invest in the right dehumidifier model, be it big or small, based on how much moisture removal you require, the area coverage, water removal into a bucket or can be directed into an outlet, etc.

This is what dehumidifiers can do in the rooms you have placed them in. It removes the moisture in the air and can make it breathable and fresh. This dry air that is moisture-free will give you the effect of feeling cool. Remember, just the COOLING EFFECT.

If you want to cool a room, you definitely have to invest in an air conditioning unit. Now air conditioners get in contact with the outside air and blow in cool air inside the room. They really do decrease the temperature that exists within the room and generate cool air. Unlike dehumidifiers that only provide the pretense of coolness, an air conditioner can truly guarantee you that.

Should you run a dehumidifier and air conditioner at the same time

ac vs dehumidifier

Before you start, you need to understand what is your number one issue regarding the indoor weather. Is it Humidity? Is it High Temperature? If you are using an AC, which typically pulls the moisture out of the incoming air, unless you’ve got a major humidity problem, there should not be any need to run the dehumidifier.

Why the room feels cool when a dehumidifier is on?

Here goes a smart question. A room does feel cool when a dehumidifier is on when actually a device running should be (and it does) generating heat, if not anything else. But how does a room feel cool when a dehumidifier is on? This is precisely why confusions are raised among a lot of people on what exactly a dehumidifier does.

The science behind this is to do with the sweating mechanism of our body. When the temperature around you is high, your body gets heated up. As a result of this, your skin begins to sweat profusely in order to cool your body down. Evaporation of the sweat from the skin surface happens and you feel light and cool, although you may be at the loss of some energy from the heat around you.
However, this is not the case with increased humidity. Here, the humid air is already laden with enough moisture. When you sweat under such conditions from the heat, the evaporation of sweat from the surface of the skin does not happen. Rather than feeling cool, you end up feeling heavy with water, suffocated, and hot. This is why dehumidifiers are recommended for homes to deal with increased humidity.

So when a dehumidifier is on in a room, it actively removes the excess moisture from the air, thereby bringing down the humidity. This will facilitate sweating and the resulting evaporation of sweat from the skin. You will instantly feel better, less hot; leading to believe that the room is cool when the dehumidifier is running.

How to make a room cool (7 Proven Ways)

There are several ways to cool a room that will bring down the temperature. Handling the heat in a room can be done in any of these following ways without having the need to invest in expensive equipment.

1. Portable AC Units: An AC on wheels, what a brilliant idea to experiment with! These are convenient options that a lot of people are turning towards. All you got to do is just plug it in and vent it out through any window. They cool down a room quickly and effortlessly.

2. Window Unit: Air conditioning window units are another smart option. All you need is a window where you can attach it; this light air conditioning window unit will drain the water outside while cooling the room.

3. Ceiling Fan: Although a ceiling fan does not lower the room temperature in any way, they are excellent at making the room cooler. Ceiling fans circulate air that is already present in the room. Even if the room in the air is heavy and hangs around people, when a fan blows air it helps the body to release the heat via sweating and evaporation of the sweat.

4. Turn Off Appliances: Are there any electronic appliances that can be turned off in your right when they are not in use? Every appliance generates heat while running and it can be a contributing factor to you feeling the warmth in the room. If they can be turned off when they are not being used, you can do so to consequently cool the room down.

5. Curtains: Heavy dark blinds on windows will prevent the room from heating up by blocking the sun rays. You can cover the windows during the day so that the room is a lot cooler at night when you sleep.

6. Exhaust Fans: Drawing out the heat from the room and releasing it out is exactly what an exhaust fan does.

7. Box Fan and Ice: Fill a bucket with ice and place it in front of a box fan; on the floor in the middle of the room. When the fan blows it can circulate air and cool down the room. This might work well for small spaces to lower the heat level.

Which dehumidifier is best for a single room?
