Does a dehumidifier cool a room

Does a dehumidifier cool a room [2023 Update]

it’s true that a dehumidifier is one of the best devices to remove moisture from your room, but do you know that a dehumidifier can also be used to deal with hot weather climates?

Well, to be accurate you should know that a dehumidifier can’t be used to remove the heat from the room. So overall you can say that a dehumidifier doesn’t cool down a room. More ever some users noticed that a dehumidifier may produce heat in the room.

But the fact is always true that a dehumidifier will take a huge role to make your room more comfortable, and can help you to protect everyone from various health issues, allergies, etc.

More ever a dehumidifier can also help you to stop the growth of mold & mildew, which can be damaging and dangerous to your health and belongings.

Well, this is why I believe that knowing and understanding how most dehumidifiers work and what they do can help us answer the question as well “does a dehumidifier cool a room?”

However you should know that a dehumidifier does not reduce temperature directly, it creates a completely dry atmosphere that is cool and gives a comfortable feeling. So in a way, it is true and also not since a dehumidifier produces a slightly high temperature.

Well, whatever the case is…let’s just find out the truth through this whole article…

Where does the heat come from?

Basically, the heat that I was talking about earlier comes from the compressor of a dehumidifier. As long as you will be running your dehumidifier the compressor of your device will continuously produce some extra heat, which will be rejected from the unit through the condenser.

So you can say that the dehumidifier can add some heat to your room which will not be noticeable but surprisingly comfortable.

As I said earlier that a dehumidifier removes excess moisture in the air by drawing it in from the outside and cooling it. Basically, a refrigerant dehumidifier draws in air and then passes the air through a cold coil to condense the moisture.

As a result, the device will subsequently drop water into a reservoir at the bottom of the machine.

However, it’s not the case in a desiccant dehumidifier since it uses an absorbent material, such as silica gel or Zeolite, typically formed into a rotor. So whenever the air will pass through the rotor the desiccant material will remove moisture from the air.

In both cases, there was nothing happened that can affect much to the temperature of your room much, but you may feel cooler while the process.

Since a dehumidifier isn’t the same as an air conditioning unit, so there’s no way that the air will be cooled down or cause a huge difference in room temperature.

However, a dehumidifier does make the air more comfortable while removing the moisture so you may still feel some cool atmosphere, or sometimes because of the heating coil you may feel the unnoticeable warmness. (Either way, both are very comfortable so there’s nothing to worry about)

Note: If you are feeling warm in your room then it’s not probably because of the dehumidifier so I suggest you buy a conditioner to use. Since there are other benefits you can get by running both devices at the same time.


Q: Can I use a dehumidifier instead of an air conditioner?

Since dehumidifiers remove humidity but can add warmth to the room, they are best used when the ambient temperature is not already too hot and can be a cost-effective alternative to using the air conditioner.

Q: Is a dehumidifier better than an air conditioner?

A dehumidifier will remove excess moisture without significantly lowering the temperature. On the other hand, an air conditioner will reduce the humidity and lower the temperature significantly. Therefore, dehumidifiers are best used in situations where moisture (humidity) is a problem and where significant cooling is not required.
