Does A Dehumidifier Cool (Or Heat) A Room?

Now this can be a tough question to answer! Based on the place you live in, a dehumidifier machine can make your room cool OR hot.

According to iallergy.com dehumidifier works like an air conditioner with a difference that it does not actually cool a room.

Instead when the unit is turned on and the compressor is running, it slowly makes the air inside the room hot by releasing back the dried and hot air in the room.

Studies shows that above holds true in case you operate the unit in very hot summer days when there is very less or no humidity in the air.

Alternatively when you operate a dehumidifier unit at a place with high humidity, it makes the air inside the room less humid, dry and cool.

During the hot sunny days when there is high humidity present in the atmosphere – running a dehumidifier and an air conditioner at the same time – can actually help in cooling your room faster.

When To Use A Dehumidifier – Winter Or Summer?

Studies reveal that at most of the times people need to have a dehumidifier in their home during spring, summer, and early fall. This is the time when there are high chances of air getting too humid in the atmosphere.

As the temperature falls during winters and the air gets colder & dryer, there is very less need of operating dehumidifier in the homes.

Instead, for people suffering from asthma and similar conditions, it is important to keep the room temperature and humidity in control by installing a heater and room humidifier in winters.

Tips for Choosing Best Dehumidifier for Asthmatics

There are so many types and brands of dehumidifier available for the domestic usage. As all the dehumidifier machines are not same and does not work efficiently for asthma patients; you need to check the features and working before making a final purchase.

As such there are certain criteria for choosing the best efficient portable dehumidifier for your home. You should concentrate on them and analyze them best before buying. These are as follows:

1- Capacity of the Dehumidifier: The capacity of the dehumidifier does not refer to the water capacity it stores; it mainly refers to the amount and capacity (rated in pints) to remove the excess moisture from the air per day.

For example, if you are seeing a “50 pint dehumidifier” it means that the device is capable of removing 50 pints of moisture in 24 hours.

Generally the large capacity dehumidifiers works better and faster than the smaller units. The main advantage of using large capacity dehumidifier for your home is that its atmospheric coverage is higher. At the same time the tank emptying interval is higher and sound output is low.

2- Dehumidifier Sound: The sound coming out of the dehumidifier, when it is in working mode, is completely unavoidable because it mainly originates due to rapid movement of the compressor fan. However the frequency of the sound may depend on the quality of the unit you choose.

Hence you can choose a dehumidifier which produces less noise. Alternately you can select the dehumidifier which comes with the speed adjusting feature. In such type of dehumidifiers you can adjust the speed of the compressor fan according to the home atmosphere. The sound from the dehumidifier will also be minimized considerably when you lower the speed.

3- Automatic Feature: Most of the modern day dehumidifiers works automatically. This means, by choosing the latest model you can sit relaxed and enjoy healthy air by simply switching ON the machine.

If the atmospheric air inside the room is more humid, then the dehumidifier machine automatically works to maintain optimum indoor humidity. At the same time automatic dehumidifier unit detects the water level in the reservoir chamber and switches off when it gets filled, to avoid the leakage.

4- Energy consumption: The dehumidifier machine in general is a high energy consuming device, particularly when it work continuously for a longer duration of time.

Hence when purchasing a dehumidifier try to select the product which is energy saving and at the same time cost efficient. For to save power in long run, best idea is to purchase automatic dehumidifier model as it switches off automatically.

5- Initial Cost: Always keep in mind that you do not ever judge a material’s quality by seeing its price tag. There may be instances when cheaper models of dehumidifiers may work better than the high priced model.

While the quality of dehumidifier should not be compromised, you should choose the size and capacity of dehumidifier wisely. Not only it saves on your initial cost but also it can save good amount of money in long run.
