Will a Dehumidifier Cool A Room – Time To Unveil The Secret

When summer hits and sweats start to fall, it’s time to decide if a dehumidifier deserves a space in your home.

Asking the question of “Will a dehumidifier cool a room?” should help you make the decision a lot more easily, so that’s what we’re doing in this article. Scroll down to read more!

Will A Dehumidifier Cool A Room? 

The solid answer to this question is “No.” No matter what kind of device without heat exchange with the outside you use, the heat emitting will remain in the room. A closed space can heat up because of a television, a computer, or even an air conditioner, so long as these machines do not interact with an outdoor unit. 

A dehumidifier is one of these types of devices where the heat escapes nowhere. It does not connect to another unit that lets its inner workings by-product, so not only does a dehumidifier not cool a room, it has the potential to make the room much hotter.

However, one cannot help but feel cooler when a dehumidifier is running within your vicinity. Let’s explore the reason why:


How Does A Dehumidifier Cool A Room?

If you want to use the dehumidifier correctly (now that the misunderstanding of its functions is gone), there are two ways you can go about it: using the machine on its own or with an air-conditioning unit.

#1. On Its Own

When humidity lingers in the room, it retains the heat without letting it escape anywhere. Humidity can come from the environment itself or the sweat of people within the space. The air will feel significantly hotter than it is since your sweats cannot evaporate further, and this is where your dehumidifier comes into play.

In general, a dehumidifier – while it takes out the dankness – gives you a feeling that your surroundings are cooler. The loss of humidity makes up for its inability to physically decrease the space’s temperature. 

There are currently three types of dehumidifiers on the market. Learning how these machines work will let you in on how you can improve the feel of your room, so let’s do that in the next segment of our article:

Refrigerant Dehumidifiers

First off, we have a refrigerant dehumidifier. If the name sounds familiar to you, this type of machine uses the same method of collecting humidity as your fridge. 

A cold metal plate sits in the middle of the machine and sucks in the room’s air, and condenses dankness into droplets. The process continues until the room no longer has moisture to offer, and the dehumidifier goes on standby mode.

Since it applies the same working principles as your common refrigerator, the refrigerant dehumidifier is seemingly the most effective at giving off the cooling feeling to your home space. If you live in an area with a hot climate, this is the most suitable device for you!

Desiccant Dehumidifiers

Secondly, we have the desiccant dehumidifier that works a little differently from our former model. This type of device uses a desiccant – a material that absorbs water and moisture, essentially drying up its surroundings.

For the desiccant (and the desiccant dehumidifier) to work, a lot of the material is attached to a large wheel. The machine’s motor causes said wheel to turn and create a flow of air that dries up thanks to the desiccant. The condensed water from this process goes through a tube and falls into a collection tank.

If you live in a lower temperature area, a desiccant dehumidifier is much more suitable than its refrigerant counterpart. Desiccant does not require the outside environment to have a much higher temperature than its inner workings to function and suck the moisture out of your room. 

A downside to using this type of dehumidifier is that you will constantly have to stock up on desiccant units and replace them with the wheel.

Whole House Ventilation Dehumidifiers

Finally, we have entire systems to remove moisture from your home’s air called the whole-house ventilation dehumidifiers. These systems are quite affordable to maintain and run in the house, so they have gained popularity with your typical consumers.

These units locate themselves in loft spaces and release the damp air through your home’s natural leakages. The process leaves your house dry, cool, and free of condensation. Installation is also very simple – taking at best an hour for the entire household!

#2. In Combination With An Air Conditioner

The most effective way to use a dehumidifier of any kind is to pair it up with an air conditioner or any device of the same function. Dry air tends to reduce temperature much faster, so before switching on your air conditioner, you can opt to have the dehumidifier run first to remove dampness.

When using this tactic, make sure that you keep your living space closed off so that your dehumidifier and air conditioner do not have to work twice or thrice as hard on the entire house. Close your door and shut off your windows as both these machines start working.

While using the machines in tandem with one another, there is something to keep in mind: Don’t leave both on for too long while you are sleeping, or you will wake up feeling drenched as if you have slept in a desert. Being in dry air for too long is very bad for your skin and hair, so you might want to put a timer on your cooling systems. 

Be sure to pay attention to your machines while running, and give their filters/reservoirs a wash every once in a while!


What Are Some Tips On Using A Dehumidifier?

Now that you are well-versed with the use of dehumidifiers in your home, we would like to leave you a few tips to optimize the device’s functions. These tips will also help keep the dehumidifier working healthily for a long time!

Give Your Dehumidifier An Environment To Work With

Make sure to put your dehumidifier in a room that can dry up: damp, hot, and decently spaced. If your room is too cold or too big for the capacity of your device, the changes it makes will be very minimal, and the water it collects in its tank might even freeze. A dehumidifier with a frozen tank is essentially useless!

Aside from considering the working space, you can also try to maximize the dehumidifier’s use by installing an anti-freeze system within the machine!

Maintain The Humidifier’s Condition

Since all the moisture in your room will head to the water reservoir, the tank will be full after a while. After the tank reaches its limit, your dehumidifier will refuse to work any further, and the water in the tank might even evaporate back to your room, making it hotter!

To deal with this never-ending loop, we suggest that you empty the water tank after a couple of hours of use. You may have to do this even more often in especially humid seasons as the dehumidifier works to its maximum capacity. 

You can also opt to avoid emptying the tank overall by installing a sewer system that drains the tank on its own!

Final Note

In conclusion, will a dehumidifier cool a room? No, but it can help boost the function of other air conditioning devices installed in your house.

Although the machine does not do what you assume it is doing, it can still be of great help with regulating the temperature within the room once you get the hang of using it!
