What Is A Dehumidifier And How It Works
A dehumidifier is a home appliance that removes moisture from the air. By keeping moisture down, it can discourage the growth of mold, mildew, fungi, dust mites, and pest. A dehumidifier can also help you breathe better, relieve allergy symptoms, and prevent asthma from triggering. It can also protect your home from structural damage so you and your family member will live in a healthier environment.
Here is how a dehumidifier works. Similar to a refrigerator, air will be drawn into the dehumidifier to go through the process of condensation. The humid air will circulate through the condenser that transfers the heat to the air naturally till its dew point, resulting in moisture extraction while releasing the dried air out. Droplets will either drip down to a water tank/ bucket that requires emptying every now and then, or pump straight out via a drainage hose.
While there are a lot of benefits to a dehumidifier, it is different from an air conditioner that is designed specifically to cool or heat a room.
Does A Dehumidifier Add Heat To A Room
A dehumidifier will raise the room temperature by a few degrees F that you will not feel any warmer. This is because the dry air released back into the room will be warmer than the room-temperature humid air that enters the dehumidifier. There is also excess heat discharged by the dehumidifier when air is circulating through the condenser via the compressor. Still, the small amount of heat added is dependant on the room size and how long the dehumidifier is running. Most people will not feel any differences at all.
The other way heat is added to rooms is by the compressor running, which does add a small amount of heat to rooms. It’s similar to other household appliances that add warmth to the rooms they’re placed in. Most rooms don’t see a significant or noticeable change, but some sensitive customers may notice a slight increase in temperature.
That said, a dehumidifier will play a big role in managing the room temperature despite not having a cooling functionality. A person will feel hot and stuffy when the air is muggy. As sweat cannot evaporate quickly enough, the body will have to compensate by increasing blood circulation and respiration that leads to excessive sweating. A dehumidifier can remove the excessive moisture therefore bringing the room dampness down. You will feel colder and more comfortable to breathe in when the humidity level is between 30 to 50 percent.
So in conclusion, a dehumidifier will add an insignificant amount of heat into the room, but by keeping the humidity level down, a dehumidifier can also cool down the room temperature.
How Do I Prevent Dehumidifier From Making A Room Warmer?
Staying in a hot region and worry that the dehumidifier might add “heat” to your problems? Here are ways you can make it run more efficiently with less heat produced.
- Room size – The bigger the room square footage, the cooler the room temperature will be. The heat generated by the dehumidifier will have little impact in a large room due to better airflow circulation.
- Types of dehumidifier – There are many types and sizes of dehumidifiers catered for various room sizes. Placing the wrong size dehumidifier will lead to unnecessary heat dispersion. For example, a small dehumidifier that is incapable of covering in a large room will have to run constantly to achieve the ideal humidity level.
- Run time – The less operational time a dehumidifier is needed, the less heat will be generated. Instead of leaving it running continuously, get a dehumidifier with a built-in humidistat and auto dehumidifying feature. The dehumidifier will stop running automatically once the desired humidity level is reached.
- Humidity area – If you are staying in a high humidity area such as New Orleans or Florida, the dehumidifier will have to run frequently thus more heat will be generated from the compressor. Ensure you are picking the right size dehumidifier, switch on the fan or air conditioner to counter the extra heat.
- Moisture removal – Perhaps the most important tip of all, ignore the little heat generated from the dehumidifier. You can actually feel colder and breathe more comfortably with dried air than humid air. So just continue with your daily activity and let the dehumidifier remove the excessive moisture.
