HVAC dehumidifiers help in maintaining the level of humidity in the air by taking extra moisture out of the air at homes, commercial places, and industries too. HVAC dehumidifiers are very helpful as they make breathing easier for asthma patients and people suffering from allergies.
There are mainly three main types of HVAC dehumidifiers, namely, Refrigerant, Desiccant, and Whole House. These dehumidifiers use a different method for removing the moisture. Let's look at each one of them in detail.
1. Refrigerant Dehumidifiers
A refrigerant dehumidifier can be considered as working in the same manner as the refrigerators †at our homes. Hence the name refrigerant dehumidifier. It helps in cooling a metal plate on which moisture from the air condenses. A fan draws the air through the dehumidifier and brings it over the metal plate. This way more and more of the moisture condenses which eventually drips in the dehumidifier tank. This is how refrigerant dehumidifiers keep the humidity of a room at a normal level.
Refrigerant dehumidifiers operate more effectively at typical room temperature. However, they do not perform that well at lower temperatures and require additional features. If you are looking for a dehumidifier for a room that does not have a low temperature, then a refrigerant dehumidifier is the best option.
2. Desiccant Dehumidifiers
The working of a desiccant dehumidifier is different from that of a refrigerant dehumidifier in a way that it uses a desiccant that is used to absorb water from the air. The desiccant dehumidifier consists of a wheel equipped with desiccants. When the air passes through the wheel, the desiccants absorb moisture from it. During the rotation cycle, a proportion of the wheel passing through a stream of warm air" reactivates" the desiccant by driving off the moisture. This condenses the water which is collected in the dehumidifier collection tank. The condensed water can also be drained out via a tube from the back.
The main difference between a refrigerant dehumidifier and a desiccant dehumidifier is that the latter can be used at a lower temperature. Moreover, the desiccant dehumidifier is smaller and lighter as compared to the refrigerant dehumidifier. Therefore, if you are looking for an HVAC dehumidifier for a cool place, then go for desiccant dehumidifiers. However, one thing that needs to be noted is that desiccant dehumidifiers consume a large amount of energy.
3. Whole House Ventilation Dehumidifiers
Whole House Ventilation Dehumidifiers are the most effective in removing damp, mold, and condensation from our homes. A lot of moisture in the air can cause serious issues at our homes such as molds, bad odor, etc. Whole house ventilating dehumidifiers work best for such conditions. The air conditioners at our homes work in the same manner as the whole house ventilating dehumidifiers. In the presence of whole house dehumidifiers, the air conditioner does not have to work as hard as it does. Whole-house dehumidifiers are a great addition to our homes since they purify the air and lowers the humidity level and help in getting rid of the problems associated with more moisture.
Proper functioning of an HVAC system depends on the working of the HVAC parts. It is important to check whether the HVAC parts are functioning well.
