An Overview Of The Types Of Dehumidifiers And Their Benefits.
A home that isn’t properly aired out and maintained can often end up rife with mold and other harmful things. Left untreated, mold can grow and spread throughout an entire house. This can cause harm to any people or pets living there. One solution to having a safer and healthier home is to purchase a dehumidifer. There are a few types of dehumidifers that are very helpful to keep in one’s house. These types include a commercial dehumidifier, crawl space dehumidifier and dehumidifier for basement.

Crawl Space is a part of the house that is located between the bottom of the house and the ground. It serves as a partial basement and provides a concrete foundation to the house. The term crawl space is primarily accounted to the height and depth of the area; it does not have the regular depth of a basement making it difficult for an individual to stand inside the confined area. Most of the time crawl space is made as part of the house to simply lift the house off the ground providing a considerable amount of space to separate the house and the ground; this is done to avoid direct contact to the ground especially those having termite infestations. Crawl space is an inexpensive alternative for basements and could be useful for services such as pipe, duct works and plumbing.
Why should You Worry About Moisture Problems in the home?
Having a crawl space at home also has its own disadvantages. One of these is the moisture problems. The ground to which the house stands is subjected to the presence of water; moisture is an unavoidable feature that is developed in an enclosed area that is in direct contact to the ground. Crawl space an area being directly in contact with the ground means that the development of moisture around it could grow up multiple house problems. The moisture and humidity being present in the area allows the growth of fungus, these types of microorganisms heavily favors a humid environment and could multiply and produce spores in just a matter of days. These fungus or molds grow in the walls of the area giving that ugly and disgusting look and at the same time producing mold spores to build multiple colonies. When these spores are developed they mixed with the air and are distributed and flow around the house causing problems to people especially those having allergies. Natural air flow patterns being also called as the “Stack Effect” around the house goes with drawing the air from the crawl space upward to the house, air is cooler below the ground and replaces the warm air in the house making a dragging effect of the air resulting to make the air in the crawl space area move upward bringing the mold spores and contaminating the whole house. Another problem attributed to crawl space is the presence of vermin, the humid, damp and shady features of a crawl space is a very suitable environment for vermin such as snakes, centipedes, cockroaches, dust mites, termites and etc. These types of noxious vermin are extremely hard to control and are persistent home parasites. Inhabiting the crawl space area of the house and being sucked and mixed up in the air flowing upward in to the house these things are the major cause of indoor odors of and allergies. Vermin such as dust mites causes allergies and do asthma triggers which greatly affect the health and safety of the individuals inhabiting the house.
Moisture Control, Humidity and Dehumidification
Crawl space problems depict a need for a solution, a solution in the form of a dehumidifier. Dehumidifier is a type of equipment that controls the humidity of the air, a fan draws the humid air inside the equipment and the equipment removes the moisture from the air and condensing it. The presence of a dehumidifier in the crawl space area greatly helps in having control over crawl space problems. Dehumidifiers act as air quality maintenance sector, having this type of equipment taking control of the humidity in the crawl space, it reduces the chances of molds growing in the area and helps decrease the presence of vermin.

dehumidifier structureLooking deeper into dehumidifiers it follows operating principles and ways to having control of air humidity and at the same time reduces the energy consumption. Dehumidifiers generally operate by simply drawing the air in and letting out the evaporated or dehumidified air. Dehumidifiers work by first letting the sucked air flow into the evaporator. Evaporation is a process that causes a drop in the two important factors of the air that is the pressure and temperature. In the evaporator contains a refrigerant, this type of fluid changes when bombarded with the air changes the water vapor its state from gas to liquid phase. The temperature of the air dropping below its dew point temperature and being exposed to the refrigerant, at this point the water vapor in the air condenses and water leaves the air. The condensed water called the “dew” is then dripped into a container that serves as storage for condensed form of water vapors. The air then flows to a hot condenser where it is heated up and is returned to the room or the crawl space area to be able to pick up new air humidity and the whole process is cycled back again. This process is continued over and over again until the desired amount of humidity level around the crawl space area is achieved by the equipment.

With the advancements of human technology there are already a lot of well developed dehumidifiers being sold around the globe, each having different qualities and advance function. These dehumidifiers contains humidity sensors and are very helpful in saving up energy since they will only operate at certain or critical levels of humidity level. Energy efficient dehumidifiers are a great asset for users since the maintenance of air humidity takes some time and energy. It should be considered as to how large the crawl space area in choosing an appropriate dehumidifier to provide efficiency and lessen the energy consumption of the equipment.

Crawl space is an important part of the house, like any part of the house it serves a unique function. It is the part of the house where the piping and plumbing system is located which gives it a significant role in the house. With the help of crawl space dehumidifiers the maintenance and control over the areas humidity is achieved in order to keep a clean and safe house to which people would live in and do their activities.

How to Choose the Right Size of a Dehumidifier

Most people don’t know how to choose the right size dehumidifier for their crawlspace. The most important criteria is airflow, which measured in cubic feet of airflow movement per minute (CFM). If you want to dehumidify your room effectively, you must make sure that all the air in your space must pass through the dehumidifier 3-6 times every hour.

Step 1. Through the Data of the Website (Click the following Image) and with the help of a hygrometer to gain the accurate humidity reading of your room that you want to dehumidify.

Step 2. Determine your air changes for every hour (ACH) to ascertain the airflow current required to appropriately dehumidify your room. In this step, you will get your ACH value.

Humidity Level
ACH Value
60-70% RHDamp3
70-80% RHVery Damp4
80-90% RHWet5
90-100% RHExtremely Wet6

Step 3. Ascertain the amount of square feet present in the space that you want to dehumidify.

Step 4. Calculate the amount of cubic feet in the space that you want to dehumidify. ( Multiply the height of the space by the amount of square feet of the space)

Step 5. Multiply the cubic feet value by the ACH value and divide the result by the number 60 (minutes). Then you gain the amount of cubic feet per minute(CFM).

Step 6. After you have got your CFM value, you should make sure the pints of moisture you need extracted from the air on a daily basis to properly dehumidify your space. You can find out the right Pints Per Day with help of following table.

Your Space
Square FeetACH = 60%-70% RHACH = 70%-80% RHACH = 80%-90% RHACH = 90%-100% RH

Step 7. You Should buy a dehumidifier which can support your above CFM and pints requirements.

A Crawl Space Dehumidifier

dehumidifier for crawl space

Purcasing a dehumidifier that fits into a crawl space has many benefits to you. You will first need to determine the size of the equipment you need. Think about where you will be using it and how much room you will have to work with. Taking the square footage of the space you need to use the dehumidier in will tell you what size you need to purchase. There are different crawl space dehumidifers you can purchase depending on what you actually need it for. For example, if you need to fix the damage from a roof or a pipe that leaked you will need one type while if you are living in an area that experiences high levels of humidity you will need a different type all together. For long term problems such as high humidity levels you may want to consider purchasing a dehumidier designed for a crawl space that is mean to be permanent. This means purchasing one that has a drain pump that keeps working continously. Doing so will avoid the need for a water collection tank. While permanent units are better for permanent problems correcting a one time problem such as an unexpected leak calls for a unit that is portable and that has no pump. A portable dehumidier for your crawl space doesn’t require any installation and can be moved very easily. Keep in mind that water collection tanks need to be moved periodically. A dehumidifier works by being equipped with a fan that sucks air into the machine. It then takes the moisture out of the air and sends the air back into the room. Some dehumidifiers move more air than others and the more air it moves the better it will do in a large space. One used in a crawl space will not have to circulate as much air as its bigger counterpart. The lack of an effective air mover can affects how good of a job the machine does. If it moves a small amount of air it is really only good for the immediate area the machine is surrounded by. The smallest portable dehumidifers, often used in crawl spaces, is really only sufficient for use in one small room at a time.

They are dehumidifiers that operate best with low temperatures, which is perfect for a basement since that is generally the coolest room in any house. Growth of fungus and rotting of wood are two common occurences in any basement. It is possible for people to have allergic reactions to both rotting wood and fungus. Having a dehumidifier in your basement is the best way to prevent this. The presence of fungus is one of the biggest reasons why the humidity in any basement should be kept as low as possible. To be effective in a basement a dehumidifier must have a high enough capacity to be able to remove all the moisture in the air. The higher the capacity is the better for everyone living in a home, especially if you have allergies. These dehumidifiers must be very powerful in order to do their job correctly. It is also important that when you are choosing one you make sure to get one that runs on low speeds. This will minimize the sound the machine’s fan makes. The higher the capacity of the machine the less likely you are to be able to hear the machine. The best basement dehumidifiers have frost free coils. If the coils ice over the machine will stop working properly. A basement dehumidifier should be one that is able to be restarted, otherwise if the dehumidifier loses power it will not start again until you turn it back on. An auto restart unit will protect the machine in the event that a power outage occurs and is generally much more convenient for most homeowners. How much you can run this machine depends on the climate where you live. Generally when the temperature outside dips below 65 degrees a dehumidifier will likely not work well enough to even bother with. You can only use a dehumidifier effectively all year long if you live in a climate that is regularly warm.
