How Does A Dehumidifier Work?

During the times of the year when the weather is damp, you have to deal with damp climbing up the walls. This calls for a dehumidifier as a must-have appliance in your building. If left unattended, the damp environment can, over time, lead to the growth of mildew and mold, which can result in allergy or asthma reactions. Having a dehumidifier that helps curb these problems can be a great way to help cut down the threats by improving the humidity level of the building; however, before you get one, it's best to understand how they work.

What Is A Dehumidifier?

It's a piece of energy equipment that sucks out moisture from the air in a building. It's an ideal piece of equipment to use in buildings or parts of the home that experience high humidity levels. It can also help eliminate all the allergens, pollutants, and bacteria from a building, leaving a more conducive atmosphere. If you notice the paint in the house is
peeling or the wood is warping, it's because of the high amount of moisture in the air, and it's time to get a dehumidifier.

How Do Dehumidifiers Work?

Dehumidifiers are worth it through a simple physics process; the water vapor turns into liquid after contact with a cooler surface. This equipment work by following a 2 step principle;

1. Extracting moisture from the air - this involves running the moist air in the building and running it over the evaporator (the cold coil). Here, the moisture from the air
condenses, and the resulting water collects on a drip tray into the water tank. This then results in cold, dry air.

2. Heating the dry air - the resulting dry cold air is run over the condenser (a hot coil), bringing it to room temperature. The dry air is then fun back to the atmosphere of the house.
The compressor propels the fan and the refrigerant flow in the dehumidification system. First, the moist air is drawn by the fan into the dehumidifier through the air inlet. Next, the humid air passes over the cold coils, which condenses the water from the air. Next, the drip trays in the dehumidifier trap the condensed water and store it in the water tank. Finally, the dry cold air passes through the hot coils, which are heated and propelled by the fan into the atmosphere.
Like the air conditioner, a dehumidifier uses a coolant circulating on the metal coils to change the indoor air conditioning. As moist air enters the dehumidifier, it travels over the coolant evaporator coils. As the air cools, it drops below its dew point. This is the temperature at which air can no longer hold more water. Sometimes, the collector holding
the condensed water is a removable bucket-like device. Some in-house devices have a pump and loss system or a hose to empty the collected water into the drain.

Dehumidifiers are essential in homes or commercial buildings. You can control them through the humidistat, which lets you choose the desired humidity level in your house or room. The humidistat works more like a thermostat; it regulates the moisture instead of the air temperature. Remember, dehumidifiers and air conditioners have the same functionality but one major difference. The dehumidifier expels the dry air back into the room while air conditioning expels that air to the outside environment.
