Why Do Dehumidifiers Blow Hot Air?

Is it normal for a dehumidifier to blow hot air? This is normal, but if you feel a higher temperature in the room this is not normal. Picture this: you're basking in the cool breeze of your dehumidifier, expecting a refreshing touch to the air, when suddenly, it feels like you've stepped into a sauna. It's a perplexing situation, and you find yourself wondering, "Why on earth is my dehumidifier blowing hot air?" Fear not, for we're about to unravel the mystery, exploring the common reasons behind this phenomenon and shedding light on the comfort-enhancing solutions. Join us on this journey as we navigate the world of dehumidifiers and discover why they occasionally bring the heat.

 

Understanding the Dehumidification Process:

 

Before we dive into the warmth mystery, let's quickly grasp the science behind dehumidifiers. These appliances work wonders by pulling in humid air, cooling it down, extracting moisture, and then releasing the drier air back into your space. The extracted moisture is either collected in a reservoir or drained away, leaving you with a more comfortable environment.

 

Should the Air Coming Out of a Dehumidifier be Hot or Cold?

 

The air that comes out of a dehumidifier is usually slightly warm. This is because dehumidifiers work by removing humidity by cooling the air, causing the moisture to condense into droplets and be collected. Then, to prevent the cooled air from becoming too cold affecting room temperature and comfort. The dehumidifier reheats the treated air. This keeps the temperature of the expelled air similar to the room temperature and maintains a comfortable indoor environment.

 

Why Dehumidifier Blowing Hot Air?

 

 

Defrost Mode of the Dehumidifier

 

A common condition that causes hot air to vent is defrost mode. In colder conditions, frost can build up on the coils of the dehumidifier. To solve this problem, the dehumidifier intelligently switches to defrost mode, in which the coils are gently heated to melt the frost. But don't worry, the dehumidifier's defrost mode is usually switched on during low winter temperatures. And it lasts for a short period of time.

 

Compressor Failure

 

If your dehumidifier is a compressor type, the compressor will generate some heat when working. But this is normal. However, you need to be aware of excessive heat and you need to be aware of any problems with the dehumidifier that are preventing the machine from dissipating heat.

Using An Inappropriately Sized Dehumidifier

 

If you then use a large dehumidifier in a small room, it can lead to excessive dehumidification, over-drying of the room and poor cooling. The heat generated by a large dehumidifier when it is working can raise the temperature of a small room quickly. So it can give the illusion that the dehumidifier is blowing hot air.

Dirty Filters

 

Regular cleaning of your dehumidifier is very important. If it is not maintained and cleaned on a regular basis, it can lead to dust build-up. The dehumidifier runs less efficiently and dissipates heat poorly, leading to higher temperatures in the blown air. It is recommended that cleaning and maintenance be performed at least once a month.

Preventive Measures And Maintenance Tips

 

Prevention and Maintenance

Taking preventative measures and maintaining your dehumidifier can help prevent problems such as hot or warm air blowing out.

 

Proper Location

Place the dehumidifier where there is enough space around it to allow air to circulate freely, increase dehumidification efficiency, and not cause the machine to overheat.

 

Dehumidifier Smart Mode

By choosing the smart mode of the dehumidifier, you can set the desired air humidity, and the machine will automatically adjust the efficiency of dehumidification according to the humidity, which can reduce energy consumption and the machine will not work for too long.

 

Regular maintenance and cleaning

Regularly clean the dehumidifier filter and interior, regularly check the machine circuit and power cord for problems and corrosion.

 

Conclusion:

 

Dehumidifiers are blowing normal temperature air, if you feel hot air with your hands, check the machine for malfunctions. If you still want to know other problems of dehumidifier you can contact CROSSBOW, we have professional engineers to answer for you
