HOW TO CHOOSE YOUR DEHUMIDIFIER

Dehumidifiers can be used in a large number of applications, but the dehumidifier has to have appropriate power to fulfill its purpose. Read about ways to select the right dehumidifier and use the efficiency calculator we developed for you.

Formula for calculating recommended air displacement of dehumidifier:

V x 3 = [m³/H] (L x W x H) x 3 = mVh

Example Building:

  • Width: 4m
  • Height: 4m
  • Length: 5m

V = 4x4x5 = 80m³

Recommended dehumidifier's air displacement = 80 x 3 = 240 mVh

The smallest dehumidifier that you can use in that type of a room is DH721 with air displacement of 240 m³/h.

By choosing the bigger capacity dehumidifier, you can shorten the drying process. Please remember that drying too quickly can damage the drying surface.


HOW TO IMPROVE DEHUMIDIFICATION PROCESS

  • Close windows and doors,
  • Place the dehumidifier in the middle of the room,
  • Keep dehumidifier away from heat sources,
  • Store and transport dehumidifiers in the upright position is recommended,
  • The efficiency of the dehumidifier can be increased with an electric heater or an infrared heater working in the same room,
  • The efficiency of the dehumidifier can be increased with a blower working in the same room.

WHOLE-HOME HUMIDIFIER & DEHUMIDIFIER SOLUTIONS AUTOMATICALLY DELIVER THE PERFECT AMOUNT OF MOISTURE & DRYNESS TO YOUR HOME


Dehumidifiers Stop Mold in its Tracks

Mold and mildew reside where it's moist: shower curtains, windowsills, air conditioning ducts, and sinks. In homes where humidity is very high, mold can even form on furniture or in carpets. While it's gross to look at, mold and mildew can also cause issues with breathing for those who suffer from allergies or asthma. A crawl space dehumidifier makes it more difficult for mold to thrive by cutting back the humidity it needs to flourish.

It is wise to also keep your holiday home and RV fitted with a maintenance free dehumidifier, possibly on a timer to keep the mold at bay even when you are not around to keep an eye on things! Also, consider a basement dehumidifier as this is often a primary source of household mold and damp issues.

Dehumidifiers Improve Your Health With Cleaner Air

It isn't just mold and mildew that thrive in a moist environment. Other allergens and disease-causing bacteria love places that are wet - challenging the efficiency of an air purifier vs dehumidifier. Home dehumidifiers help to reduce the number of these pathogens too, keeping the air you breathe cleaner and healthier.

Dust-up the Dust Mites By Removing Moisture

These tiny critters are so small that you can't even see them without a microscope. They live in your bed linen, curtains, carpets, floor mats, furniture, and pillows and are near impossible to remove. They literally get nourishment from the moisture that gets trapped in random areas of the home, and from there they multiply. Dehumidifiers help to keep their numbers in check by keeping things dry destroying their ideal environment.

Protect Your Belongings For Mold Damage

Storing certain electronics, books, clothes, paintings, posters, and even some foods can become damaged by ambient moisture. These important and sometimes expensive things you own will last longer if the humidity levels in your home are kept under control. Basically, if you store anything in your basement, a basement dehumidifier is nothing short of essential.

Controlling excess moisture in your home brings benefits that expand beyond mold control. Dehumidification is an easy and relatively inexpensive way to improve air quality, bolster your health, especially for those prone to asthma, allergies and hayfever, and protect your possessions.

Both home and commercial dehumidifiers come in a range of sizes from small one-room units to whole-home systems; the sizes are based on the system's ability to remove moisture from the air. Regardless of what your needs are, there's bound to be a dehumidifying system out there that's perfect for you.

Whole-Home Dehumidifiers are located out-of-sight and out of your way with quiet operation, hassle free maintenance and up to four times more energy efficiency than the leading portable dehumidifier.


Improving Home Air Quality With Humidifiers & Dehumidifiers

The humidity or lack of it, in your home can make a big difference in your overall comfort. Too dry or too moist air can be both harsh and unpleasant. Sticky, humid summer-like air makes many of us miserable. And very dry, heated air in winter wreaks its own special havoc on our bodies. Achieving well-balanced, whole-home humidity control in every season can not only provide exceptional comfort, but can prevent health problems and at the same time, protect your home.

Mold and mildew reside where it's moist: shower curtains, windowsills, air conditioning ducts, sinks and wall cavities. In homes where humidity is very high, mold can even form on furniture or in carpets - using a portable dehumidifier is an immediate step to rectifying the problem though a crawl space dehumidifier is recommended.

While it's gross to look at, mold and mildew can also cause issues with breathing for those who suffer from allergies or asthma. A dehumidifier makes it more difficult for mold to thrive by cutting back the humidity it needs to flourish.

It isn't just mold and mildew that thrive in a moist environment. Other allergens and disease-causing bacteria love places that are wet. Dehumidifiers help stop mold and also assist to reduce the number of these pathogens, too, keeping the air you breathe cleaner and healthier.

According to Peter Blaha, Product Marketing Manager for April aire dehumidifiers, whole home dehumidifiers pull air from every room in your home through the return ducts. It removes the moisture and then sends dry air back throughout your home. It works in conjunction with your air conditioner heat pump to efficiently balance the humidity levels in your home, but can also work independently on days when you don't need the air conditioner.

He recommends keeping relative humidity levels below 60% in your home to keep mold and mildew from growing and to keep that musty smell at bay.

"Our dehumidifiers help by removing excess moisture and reducing the damage that mildew and mold can have on the sustainability of your home and the health of your family" he continues.


A whole-home dehumidifier extracts the moisture from your home. And an Energy Star rated whole-home dehumidifier like Aprilaire's 173QA can help qualify your home for the Green-Built Certification Program of the National Association of Home Builders.

Why Humidifiers?

Dry climates obviously can benefit from humidifiers, but winters can be even more brutal when heated very dry air is circulating in your home. Maintaining a proper humidity level in your home is important for several reasons. The recommended average relative humidity is between 35 percent and 45 percent, this range providing the best comfort for your family, while helping to protect your belongings (especially ones made of wood from floors to furniture) from damage caused by dryness.

And low humidity can affect your skin by exacerbating skin diseases like eczema, psoriasis, and dermatitis. Even if you don't have a diagnosable skin problem, you can still suffer associated symptoms, such as dry, scaly, itchy skin. These issues can worsen in colder months, when the skin is more likely to become depleted of moisture. This is commonly referred to as "winter itch," Dry air will draw moisture out of your skin, potentially causing small cracks on your skin's surface - this is where you need a humidifier. Cracked skin increases your risk of becoming sick by providing an entry way for possibly dangerous pathogens.

Dry air also takes its toll on your eyes given its known to increase the evaporation of tears, possibly disrupting the moisture balance necessary for a healthy and comfortable eye surface. And then there's the havoc wreaked on your sinuses. Many people just apply skin creams where as a simple humidifier would be the logical whole-home permanent solution.

A recent study found that nasal congestion may be related to the temperature and humidity of inhaled air, possibly more than any other variable. While high humidity is known for causing nasal congestion, dry air can as well. Very dry air dries out your sinuses to the point of irritating the membranes, leading to inflammation. And flu viruses survive longer and spread more easily in low humidity, According to research published in Environmental Health Perspectives, keeping proper humidity Eevels may help to lower rates of respiratory infections and allergies.

With whole-home humidifiers, the correct amount of moisture is delivered throughout your home.

Dehumidifiers USA is your solution for air in your home that's too dry or too humid. Dehumidifiers USA are experts in indoor air quality and will help you achieve balanced humidity levels in your home to keep you comfortable but also healthier with Aprilaire humidity-control products including whole-home humidifiers, basement dehumidifiers, crawl space dehumidifiers and commercial dehumidifiers. Help keep you and your family comfortable and breathing easy.


DEHUMIDIFICATION TECHNIQUES

Heating and ventilation

Dehumidifying by ventilation and heating Dehumidifying by ventilation and heating: 1 - air removed outside; 2 - air sucked from outside; 3 - extractor fan; 4 - heater; 5 - heated air.

This method consists in raising air temperature in a room and applying intense ventilation. Its efficiency depends on external conditions that can even make it impossible to use the method. The lower external temperature and the higher temperature of the dehumidified room, the more effective the method.

Thus, the best effects can be achieved in winter, worse in the spring and autumn, and the worst ones in summer. In the case of dehumidifying humid walls, temperature in the room should not exceed 35°C. Higher temperatures can cause cracking and damaging of the walls. Lack of proper ventilation (air exchange) while dehumidifying humid walls with this method causes steam to be absorbed by drier parts of walls and the ceiling.

Using this method is often expensive, due mainly as a result of its low effectiveness (long time of dehumidifying) and the fact that the best effects are achieved at the largest temperature differences (large demand for heating power). A permanent crawl space dehumidifier may be a better option drawing air through the wall cavities.


Condensation dehumidifying

Condensation dehumidifying Condensation dehumidifying: 1 - humid air; 2 - filter; 3 - evaporator; 4 - dripping tray; 5 - condensate tank; 6 - dehumidified and cooled air; 7 - condenser; 8 - extractor fan; 9 - dehumidified and heated air.

This method consists in removing humidity from the air by cooling it below the dew point which causes outdropping of humidity (condensation). Condensation air dehumidifiers are used in this method. Their main elements include extractor fan, compressor, heat exchangers (condenser and evaporator), and expanding element. The temperature of air coming out of dehumidifier is 3-8°C higher than the temperature of sucked air.

The above- mentioned temperature increase may cause faster evaporation of water e.g. from wet walls which facilitates dehumidifying and does not pose a risk of damaging as in the case of dehumidifying by heating and ventilating. The amount of water contained in the air is effectively decreased along with expansion of operation time of machines in a closed room.

Effectiveness of condensation dehumidifiers depends on operating conditions (temperature and humidity) and on type of machines. It reaches its maximum value with higher values of temperature and relative humidity. Condensation dehumidifying is definitely more effective than and economical than drying by means of heating and ventilating primarily thanks to eliminating exchange of air contained in the room.


Adsorption dehumidifying

Adsorption dehumidifying Adsorption dehumidifying: 1 - filter; 2 - humid air; 3 - rotor; 4 - dehumidified air; 5 - extractor fan; 6 - regeneration air; 7 - heater; 8 - hot regeneration air; 9 - humid regeneration air.

This method consists in removing humidity from the air by its absorbing by hygroscopic materials. The main devices used in this method are adsorptive dehumidifiers whose major elements include rotor along with a driving unit, extractor fans, air heater, filters, casing, and fittings.

The rotor is most frequently made of properly profiled aluminium sheets (creating axial capillaries) whose surface is covered with a hygroscopic substance.

Such a construction results in a large increase of humidity adsorbing area. The rotor is divided into a dehumidifying sector and regeneration sector in result of which dehumidified air is achieved behind the rotor. An advantage of this type of dehumidifying is the possibility to dehumidify air at subzero temperature.


The battle against moisture & mould

There's a need to pay heed to shelf life of equipment; it is unfair to blame the manufacturer for selling faulty equipment.

In the battle against moisture and mould, it is important to pay heed to the shelf life of equipment.

The end-user must bear in mind that all equipment have a shelf life for a limited number of years, and after that period expires, the equipment must be replaced, otherwise the problem will always be prevalent, and the manufacturer is blamed for selling faulty equipment.

Generally speaking most businesses in the HVAC industry are of the view that the battle to combat moisture and mould is a recurring process in the GCC region and needs specialised expertise.

Menezes calls for a thorough approach to tackling mould in ducting systems. "Cleaning the filters is not enough."he said.

If the coils of the equipment are also cleaned thoroughly and the filters replaced periodically, the ducts will remain intact The other factor is maintaining a standard temperature, because a swing in the temperature causes the problem.

One of the main problems with mould and moisture in HVAC equipment is high humidity conditions in the region.

The other problem is when the piping or ducts of the HVAC equipment have small holes, allowing unfiltered air to be sucked into the system.

The only way to tackle the problem is by deploying specialised expertise. Elaborating on the work involved.

We clean the ducts for these harmful substances and use a special anti-fungal paint to prevent it from recurring.

If the humidity in the room is high, then it is advisable to install a de-humidifier, besides ensuring that all windows are sealed properly and the temperature is set between 22 and 24 degrees C.

Also for deep cleaning, companies use robots equipped with spray solutions and brushes. These robots enter the duct and vacuum out the mould and moisture.
