How Does Air Conditioning Lower Humidity?

Air conditioning products have become an integral part of our lives, especially in regions with hot and humid climates. Not only do they provide us with relief from scorching temperatures, but they also help create a comfortable indoor environment by reducing humidity. But how do they actually work?

Let’s turn down the heat and explore the science behind how air conditioning equipment lowers humidity and the benefits it brings…

Humidity refers to the amount of moisture or water vapour present in the air. It is typically measured as a percentage and plays a crucial role in our perception of comfort. High humidity levels can make us feel sticky, sweaty, and generally uncomfortable. On the other hand, low humidity can cause dryness in our skin, eyes, and respiratory system. Achieving the right balance of humidity is essential for maintaining optimal comfort.

How does Air Conditioning Work?

Air conditioning products are designed not only to cool the air but also to dehumidify it. While the cooling aspect of air conditioning is well-known, the dehumidification process often goes unnoticed. 

Evaporator Coils and Condensation

Air conditioning equipment consist of an evaporator coil and a condenser coil. The evaporator coil is located inside the indoor unit, and it plays a crucial role in dehumidifying the air.



Here's how it works:

Cooling the Air

The air conditioning system draws warm air from the room into the indoor unit. The air passes over the evaporator coil, which is chilled by a refrigerant.

Condensation Process

When warm air encounters the cold surface of the evaporator coil, moisture in the air condenses onto the coil. This moisture is removed from the air and collected in a drain pan.

Air Dehumidification

As moisture condenses on the evaporator coil, the air becomes drier. The dehumidified air is then re-circulated back into the room, providing a more comfortable environment.

Enhanced Comfort

Lower humidity levels make us feel cooler, as our bodies can effectively release heat through perspiration. This helps combat the sticky feeling associated with high humidity.

Mold and Mildew Prevention

High humidity encourages the growth of mold and mildew, which can lead to health issues and damage to property. Air conditioning equipment helps control humidity, inhibiting the growth of these harmful organisms.

Improved Indoor Air Quality

Lower humidity reduces the likelihood of dust mites, allergens, and other airborne pollutants thriving in the environment. This can alleviate symptoms for individuals with allergies or respiratory conditions.

Preservation of Goods

Excessive humidity can damage sensitive materials like electronics, wooden furniture, and artworks. Air conditioning equipment helps maintain a stable environment, preserving these items from potential moisture-related issues.
