What is a dehumidifier?
A dehumidifier is an electrical appliance which reduces the humidity level in the air. By continuous operation, it keeps a constant level of humidity in the air. Keeping the correct humidity level is essential for human comfort. Also, it helps in reducing mould. In commercial applications, many product storages require specific humidity levels. Dehumidifiers help to maintain these levels. The basic operation principle is by extricating water from the air. Different models based on capacity and technology are available for residential and commercial usage. Warehouses and commercial buildings will require very large dehumidifiers. Also, indoor ice rinks and swimming pools generate very high levels of humidity. They require dehumidifiers of high capacity. Just like an air conditioner controls the air temperature in a room, a dehumidifier controls the humidity in the air. This process is known as dehumidification.
How to select a Dehumidifier?
There is a wide range of dehumidifiers from various manufacturers. You may follow these guidelines:
- Identify your desired humidity levels based on the applications of the area. You can see a guideline of recommended humidity levels.
- Check your current humidity levels using a hygrometer. If it is a home, you may not need to go into these details and may select one of these models.
- Take the measurement of the room.
- You should know the current temperature levels for the calculation.
- Use our free software to calculate the required dehumidification capacity.
- For applications above 10°C, select a condensation type dehumidifier.
- For applications below 10°C, select a desiccant type dehumidifier.
These are broad steps for selecting a dehumidifier. Please check with us before your final decision.
Working Principle of a Dehumidifier
A condensation dehumidifier works by extracting water from the air, thus keeping the air dry around its environment. The fan in the dehumidifier collects air by sucking it in. The cold coils of the dehumidifier condense air to extract the moisture from it. This water goes into a drain or inbuilt water tank. Thus the air going out of the dehumidifier will be dry compared to the air intake. Thus in dehumidification, wet air is sucked in and dry is air is exhausted.
Every high-quality dehumidifier has a humidity control to regulate and operate at its optimal specification. Thy hygrostat is similar to a thermostat in operations. You can set the humidity levels that you require inside the area. Once a level is set, the dehumidifier will automatically shut off the dehumidification of air once the value is reached.
If there is no hygrostat, the machine will work continuously. For huge areas and construction sites, machines are operated without hygrostat. However, for indoor applications, there will be a hygrostat.
For a living area, the maximum comfortable humidity will be around 65-70%RH. If you have a respiratory problem or you have allergies, you will especially feel uncomfortable above this range. Also, wet air deposits itself onto the walls and cause formation of mould and fungi. Too much humidity can lead to mould growth, dust mite, and fungus. A high level of humidity also attracts unwanted insects like centipedes, spiders, and millipedes who all thrive in moist environments. With the help of a dehumidifier, you can stop this from happening.
Reasons Dubai residents need a Dehumidifier
Dubai does not experience high humidity the whole year. However, its summers are very hot and humid. September is by far the most humid month with humidity levels reaching as high as 90%. There are two main reasons to explain the atrociously high levels of humidity in Dubai. The first one is that the country is located within the Northern desert belt which is mainly characterised by arid subtropical climate. The second one is the presence of the sea. If the wind blows from the coast, it usually gets very humid. Also, there can be heavy fog. These factors contribute to the unusually high levels of humidity in Dubai.
As you can see, the humidity situation in Dubai tends to be generally high given that the city is located on the coast. High humidity has several disadvantages. These include the following:
Prevents formation of bacteria, mites, mould and mildew
High humidity, especially in the summer months, provides favourable conditions that encourage mould formation and thriving of mites at a very rapid rate. Since mould, mites, and mildew require a constant supply of moisture to survive, you can expect to suffer from this problem. A dehumidifier is important as it reduces the moisture in the air and hence helps you control mould and dust mite formation.
Prevent yourself from health issues
High humidity is associated with a raft of health issues because it is the main cause of bacteria formation. High humidity can lead to sleeping disorders, respiration problems, burning of eyes, throat, and nose, asthma and allergies brought about by mould spores. The perfect solution for this problem is investing in a dehumidifier that has an efficient filter.
Prevents potential damage to your property
If the air contains too much water, it will condense on cooler surfaces like walls and window glasses. If this water is left to stay on your walls and windows, it poses a real danger of damage to your property. It can also damage your painting, important file records or valuable books and other properties.
Damage to electronic equipment
If you have expensive electronic equipment like Flat Screen TV, home theatre or cameras, they are at the risk of being damaged by high humidity. High humidity in homes leads to water condensing on PCBs of electronic gadgets or even rusting of PCB. By installing a dehumidifier, you could stop your electronic gadgets from being terribly destroyed.
Damage to carpets and clothing and bad smell
It is not uncommon to visit a posh house and then be met with a bad smell. The bad smell is brought about by high humidity. High humidity can also damage expensive clothing items and your carpet.
So what would you prefer? Purchasing a dehumidifier or putting your household property and building at risk? The simple solution to all the above problems is to invest in a dehumidifier. As you can see, there are many reasons to invest in a dehumidifier.
How to reduce humidity in a home in Dubai
As beautiful as Dubai is, humidity and heat can be a nightmare. At such times the only solution might be to go indoors to your cooled room. But what if you have to deal with humidity problem outdoors and indoors? To put it simply, that’s just plain torture. In this section, we tell you the top three things to do to reduce humidity in your Dubai home.
Improve Your Home’s Air Circulation
If air is properly circulated in the room, it can dramatically reduce humidity in your home. A room without proper circulation feels stuffy and there is a feeling as if the air is stagnant. This usually leads air to become denser and a rise in humidity.
To improve circulation, use ceiling fans and where necessary, extra floor fans and box fans. Properly circulated air in the room dries out and reduces the humidity. This makes them cooler and comfortable. Ensure ceiling fans are rotating properly for the season. During summer, the proper way for fans to rotate is counterclockwise. During winter, you should reverse rotating direction so that cooler air is pulled up, while warmer air is rotated around the room.
Take advantage of kitchen and bathroom exhaust fans
Ventilation fans in your bathroom and kitchen are usually used to reduce bad smells in these rooms. The rooms tend to produce a lot of moisture and lack of ventilation quickly leads to mould growth.
Use the vents in these rooms to reduce excessive humidity and the rooms will be safer and even more comfortable. Ensure that these vents are not stopped or blocked in any way. Always ensure that the vents are kept clean and don’t have any debris and dust.
Preventive maintenance can go a long way in ensuring proper levels of humidity in your home. Always make sure that you schedule regular maintenance on the major units in your homes like hot water system and HVAC systems as this will ensure long life and efficiency.
Also, you can perform the following preventive measures to reduce humidity in your Dubai home:
- Watch out for any leaks in your ceiling.
- Check seals and replace weather stripping and caulk around windows and doors which can let in hot and humid air
- Inspect your air ducts for moisture and ensure that they are properly insulated
Reduce the overall moisture in your home
A dehumidifier is the surest and the most efficient way to check the humidity in the rooms of your home. If only certain places in your home experience high humidity, a basic dehumidifier might help. However, if you have humidity in the whole of your house, you may want to buy a whole-house unit. A dehumidifier is not part of your AC system and can be run independently of your AC unit. It can also operate on days with high humidity but temperatures are reasonable. A dehumidifier combined with your air conditioning unit will dramatically improve the moisture-removing capability of the units.
Using less water for shower is another way to decrease moisture in your home. When bathing, ensure you take shorter and cooler showers as this will reduce the amount of steam in the bathroom.
Watering the plants
Removing houseplants also a good way of reducing humidity in the house. This is because plants usually release moisture in the air and if you have lots of houseplants, they could be the reason for the high humidity in the house. You can either put these plants outside during the humid months or have them concentrated in one room.
Applications of dehumidifiers
A dehumidifier is used for various residential, commercial and industrial purposes. While a rise in temperature is noticed immediately, a rise in humidity gets unnoticed and will cause adverse effects in the long term. Some of the wide areas where high-quality dehumidifiers find their applications include the following.
Humidity in the air results in a damp environment which is a breeding ground for fungus and insects such as moths, and fleas which require damp environments to breed. In certain cases, the humidity in the air leads to respiratory and perspiration issues in the human body. Dehumidification of air keeps the health issues away and the environment free from pests.
A humid climate is extremely uncomfortable as it causes excessive sweat and perspiration of fluids from the human body leading to dehydration and nausea. The precipitation levels of the body vary due to moisture leading to fatigue quickly.
While human lifestyle becomes uncomfortable due to the humidity in the air, it also causes issues in material objects such as pipes and grills to rust. These get rusted more quickly due to the moisture in the air. This results in frequent maintenance of iron ducts and pipes. A high-quality dehumidifier helps in comforting the human lifestyle. Also, it reduces the cost of repair and maintenance of households by removing the humidity in the air.
High-quality Dehumidifiers are widely used in industrial environments to maintain a certain level of humidity to create a conducive environment to produce or manufacture humidity-sensitive products. eg. ferrous materials are prone to rusting due to humidity and hence steel storage areas should have controlled humidity. Dehumidification of air is essential in such environments.
Types of Dehumidifiers
We will explain based on technology and also based on the applications.
Types of High-quality Dehumidifiers based on technology
Based on the technology, there are two types as listed here:
These are the most commonly used dehumidifiers that usually work like a refrigerator by drawing moist air. Thereafter evaporating the moisture in the air over a condensing coil, thus removing the water. The dry air is released back into the environment.
These types of dehumidifiers suit normal room temperature environments (above 10°C). The condenser coil is at an optimal temperature above 10°C. However, in colder climates, this becomes less effective. The water is collected in a tray in the machine or can be drained out through a drainage pipe. Read more on Condensation Dehumidifiers.
These dehumidifiers suck the air and pass them over a material that absorbs the moisture in the air. The desiccant material is usually silica gel. This is the most natural disinfectant that we commonly find in shipped electronic goods. They don’t condense the air over the coil and hence, they are ideal for colder climates. The wet air is taken through the inlet and the moisture content is absorbed by the desiccant. The outlet air will be dry which is recirculated in the room. Read more on Desiccant Dehumidifiers.
Sub-categories of Dehumidifiers based on applications
The major sub-categories as listed in the subsequent pages are listed below:
Adsorption & Desiccant dehumidifiers
These dehumidifiers use adsorption technology to reduce humidity. desiccant rotors are used to absorb humidity and hence these are also known as rotor dehumidifiers. Please read more on Adsorption and Desiccant dehumidifiers.
