Air-conditioned rooms should be set at 21°C for optimal comfort.
The study looked at what makes male students feel comfortable in a room with air conditioning. They checked factors like air temperature, humidity, and air movement. The students felt best when the temperature was around 22-24°C, with humidity between 52-58%. The air movement was good at 0.05-0.22 m/s. The researchers found that these factors are important for students to feel comfortable in air-conditioned rooms.
