Does A Dehumidifier Cool A Room?

No, dehumidifiers do not lower the temperature of the room. But can make you feel cooler by reducing humidity. A dehumidifier does not affect the actual room temperature, so it has a completely different effect than an air conditioner.

This article will explain to you why dehumidifiers don't lower the temperature but make you feel cooler, based on how they work.

What Is A Dehumidifier?

A dehumidifier is a device designed to reduce the humidity level in the air by removing excess moisture.Dehumidifiers are commonly used in spaces where high humidity can cause problems, such as mold growth, dust mites, or structural damage to buildings.

Dehumidifiers also have a wide range of commercial uses, for example, commercial dehumidifiers can be used in scenarios such as flood restoration, fire restoration, and removal of industrial dust and odors.

Benefits Of Using Dehumidifiers

Using a dehumidifier offers numerous advantages that extend beyond just improving comfort. From safeguarding your home to enhancing your health, these devices tackle humidity in a way that can transform your living space. Let’s break down the specific benefits, so you know exactly what a dehumidifier can do for you.

Mold and Mildew Prevention

Once humidity levels surpass 60%, mold spores thrive, and within 24 to 48 hours, visible growth can begin. By using a dehumidifier to keep relative humidity between 30% and 50%, you significantly reduce the risk of mold growth. For instance, if you maintain a 45% humidity level in a 1,200-square-foot basement, you can prevent mold from ever getting a foothold.

Improved Air Quality

By lowering humidity, dehumidifiers help remove these allergens from the air. For someone with allergies or asthma, this can be life-changing. Studies have shown that maintaining indoor humidity at 50% can reduce dust mites by 50%, thereby reducing allergen exposure and improving overall air quality.

Protection of Property

Wood, paint, insulation, and even electronics can degrade in a damp environment. A dehumidifier can protect your investment by preventing warping, rust, and corrosion. For example, a consistent 50% humidity level can prevent wood floors from buckling, extend the life of your furniture, and keep electronics safe from moisture-induced damage.

Enhanced Comfort

A 30°C room with 80% humidity can feel like 35°C, leading to discomfort and sweat. By lowering humidity to 40%, a dehumidifier can make that same room feel like 30°C, even without changing the actual temperature.

Energy Efficiency

When the air feels cooler because of lower humidity, you’re less likely to crank up the air conditioning. This can lead to significant energy savings. If your air conditioner normally runs 8 hours a day, reducing humidity can cut that down to 6 hours, potentially saving up to 25% on your cooling costs.

Odor Reduction

Damp environments foster bacterial growth, leading to unpleasant odors. Dehumidifiers eliminate the moisture that causes these smells. By running a dehumidifier in a musty basement for just a week, you can notice a significant reduction in odor.

How Does A Dehumidifier Work?

 It works by drawing in air, cooling it to condense the moisture into water, and then releasing the drier air back into the environment.

At the heart of a dehumidifier is its humidistat, a device that constantly monitors the moisture levels in your room. When the humidity rises above your set comfort level, the humidistat springs into action, signaling the compressor to get to work. The dehumidifier pulls air from your room and passes it over an evaporator coil.

This coil is much colder than the dew point of the air, causing the moisture in the air to condense into water droplets. It’s like how your cold drink sweats on a hot day—same concept, different scale. The collected water is then drained away, leaving the air drier and more comfortable.

Once the moisture is removed, the air is reheated as it passes through the condenser coil and then released back into your room. This cycle continues until the desired humidity level is reached.

Does A Dehumidifier Cool A Room?

No, a dehumidifier does not lower the room's temperature. If you expect the temperature to drop after running a dehumidifier, you’ll be disappointed. Don't confuse comfort with cooling. That's because dehumidifiers improve comfort by making the air less sticky, but they don't cool it.

Why does it feel like a dehumidifier is cooling the room? A dehumidifier’s primary function is to reduce humidity, not to cool the air. However, the way your body perceives temperature can change. Here's why.

Because when the air is humid When the air is humid, sweat evaporates slowly, leaving you feeling sticky and hot. A dehumidifier works by removing excess moisture from the air. For example, in a room with a temperature of 30°C and 70% relative humidity, the "feels-like" temperature can be as high as 35°C. If you reduce the humidity to 40%, the "feels-like" temperature can drop to 30°C, even though the actual room temperature hasn’t changed. The air feels lighter, and your sweat evaporates more easily, making you feel cooler.

So, let’s say it’s 28°C in your room. You turn on a dehumidifier, and over time, the relative humidity drops from 80% to 50%. You’ll feel cooler as if the room is now at 25°C, but the thermometer will still read 28°C. The temperature remains constant because a dehumidifier doesn’t remove heat from the air; it just changes how your body experiences that heat.

What kind of dehumidifier can achieve the "cooling effect"?

While dehumidifiers primarily remove moisture from the air, some units can create a noticeable cooling effect by improving overall comfort. This effect comes from reducing humidity, making the air feel cooler, even if the temperature doesn’t actually drop.

For those seeking this kind of cooling sensation in commercial, industrial, or restoration settings, here’s how three advanced dehumidifiers from AlorAircomemrcial can help:

AlorAircomemrcial Storm SLGR 1250X

The Storm SLGR 1250X isn’t just about removing up to 125 pints of moisture per day under AHAM conditions (80°F, 60% RH); it’s also about creating a more comfortable environment in spaces up to 3,000 square feet. By rapidly lowering humidity levels with its Super Low Grain Refrigerant (SLGR) technology, this unit makes the air feel cooler, which is vital in large industrial areas, warehouses, or during flood restoration. Workers will feel less sticky and more comfortable, especially in hot, humid climates, improving both productivity and air quality.
