The way refrigerant facilitates heat transfer is by undergoing a phase transition from liquid to gas, and vice versa. In technical terms, the dehumidifier uses a refrigeration-based and heater-based system to reduce relative air humidity from 50-100% to 30-50%. Merely saying, one removes the toxic air components, and the other prevents them from the beginning. Find out more about compressor dehumidifiers and desiccant dehumidifiers here. In a desiccant dehumidifier, moisture is removed from humid air through the process of absorption. 2. The key part of how every dehumidifier works is the refrigerant. SEER = (1 × EER100% + 42 × EER75% + 45 × EER50% + 12 × EER250%)/100, Total Heat (BTU/hr.) air), Latent Heat (BTU/hr) = 0.69 x CFM x Δgr. A method to combat humidity and all the problems it brings, is a basement dehumidifier. In turn, it uses hot coils (condenser) to reheat to room temperature. They suck air in, filter it, cool it down to condense the moisture, then reheat it and push the warmer, dryer air back into the room. To remove moisture from the air, a mechanically driven fan draws the humid air into the dehumidifier. To understand how does a dehumidifier work, however, we have to look into the device itself. After this, you have to consider how to operate the dehumidifier including the best position, and maintenance. Advertising: Tailor information and advertising to your interests based on e.g. Most people place the dehumidifier in the room where the problem is, however there are models available that monitor the entire home and can be placed wherever as long as there’s clearance for air to flow in and out and plugged into an electrical outlet like Ebac’s Smart Control. This is where the water in the air is absorbed or soaks into something; which is absorption. That being said, desiccant dehumidifiers are more expensive to run and their high extraction rate is often misused. Those suffering from allergies, asthma or the common cold can benefit from a dehumidifier. In typical fashion, dehumidifiers can be broken down into four component parts: a fan compressor, cooling coils, plastic reservoir, and reheater. A blower forces air into the unit and through the rotating desiccant wheel.

In this most common type of home dehumidifier, moist air from the room is drawn into the unit, and the processes of cooling and condensation draws the moisture out of the air. But don’t panic, it is completely normal to expect some rooms to have higher humidity than other rooms. But what a lot of us don’t realise is that there’s water in the air all around us in the form of a gas called water vapour. Such a process – a thermodynamic process – is governed by the 1st Law of Thermodynamics. Every dehumidifier follows the same 2-step principle: Extract moisture out of the air: Fan in the moist air in the house, run it over a cold coil (Evaporator) which condenses moisture out of that air and collect the water via … However, this can result in some functions no longer being available. The dried air is then reheated via a heated coil and released back into the home as drier air free from moisture. Defined by the amount of water vapour in the air, humidity greatly influences the comfort we experience in a home. Using condensation on cold refrigerant coils to remove moisture, the warm, moist air condenses into water droplets and drips into the water container inside the machine. A whole-home dehumidifier removes excess moisture in the air that's drawn in through the home's return-air ductwork. In short, the physics behind how does a dehumidifier work is quite complex. Moisture from the air condenses on the cool coils and drains into a tray.
