Yes, running an air conditioner in a room with high humidity can make the room feel colder than it would be without using the AC. However, it's important to understand the underlying mechanisms that contribute to this sensation.
When you use an air conditioner, it not only cools the air but also removes moisture from the indoor environment. The process of removing moisture is known as dehumidification. When the humidity level in a room is high, the air feels muggy and uncomfortable because the moisture in the air hinders the evaporation of sweat from your skin, making it more difficult for your body to cool down.
By running an air conditioner and dehumidifying the air, you effectively reduce the moisture content in the room. This makes it easier for your body's natural cooling mechanism (sweating) to work efficiently, leading to a more comfortable and cooler sensation.
So, while the air conditioner itself cools the air, the reduction in humidity also plays a significant role in enhancing your comfort and making the room feel colder than it would be with high humidity. The combined effect of lower temperature and reduced humidity creates a more pleasant indoor environment during hot and humid weather.
