Does an air cooler increase room humidity? Explained

Yes, air coolers can significantly increase room humidity by adding moisture to the air. Since they work on the evaporative cooling process, which releases water vapour into the surrounding air, they can increase room humidity by 10 to 30 per cent. This is dependent on the room size, initial humidity levels, and cooler operation time.

Does air cooler increase humidity

An air cooler does increase humidity and makes the room more humid than before. The increase in humidity occurs through the fundamental process of evaporative cooling, where water evaporates from cooling pads or media. The water vapour mixes with the room air, and the continuous operation leads to moisture accumulation.

The increase in humidity due to the air cooler is dependent on factors such as initial humidity, ventilation, operation time, and water tank size. A lower starting humidity allows for more moisture absorption, while poor ventilation can trap humid air. A large water tank enables continuous evaporation, and longer use creates more moisture buildup.

For small rooms, an air cooler can increase humidity by 15 to 30 per cent, while medium rooms will witness an increase of 10 to 20 per cent. A large room will witness a typical humidity change of 5 to 15 per cent.

Does cooler increase humidity

While it is true that a cooler increases humidity, its impact depends on your climate. In a humid climate, the increase in humidity can create an uncomfortable experience and promote mould and mildew growth. However, in dry climates, the increased humidity can be beneficial since it relieves dry skin and respiratory issues, prevents furniture cracking, and reduces static electricity.

FAQs

Q1: How to use an air cooler in high humidity?

A: One way to use an air cooler in high humidity is by improving ventilation or using it in combination with a dehumidifier.

Q2: Is an air cooler good for health?

A: Air coolers can be particularly good for health in dry climates, preventing dry skin and improving air quality.

Through water evaporation, air coolers inevitably increase room humidity by 10 to 30 per cent. This might be ideal for dry climates, but it can make your living environment uncomfortable in humid conditions.
