The perception of temperature is influenced by various factors, including relative humidity, air movement, and personal comfort preferences. When you set the AC temperature to 24 degrees Celsius, the cooling effect of the air conditioning system can make you feel colder than the ambient temperature of 24 degrees Celsius. There are a few reasons for this:
Relative humidity: Air conditioning systems often remove moisture from the air, leading to lower relative humidity indoors. Low humidity can make the air feel drier and cooler, which can contribute to a perception of increased coldness.
Air movement: Air conditioners typically circulate and distribute cool air throughout the room. The movement of air over your skin can enhance the cooling effect, making it feel colder than the actual temperature.
Thermal comfort preferences: Each individual has their own preference for thermal comfort. When the ambient temperature is 24 degrees Celsius, your body may adjust to that temperature and find it more tolerable. However, when the AC temperature is set to the same value, the additional factors mentioned above can make it feel colder than what you are accustomed to.
It's important to note that comfort preferences can vary among individuals, and what feels cold or warm to one person may differ from another. It's a good practice to adjust the AC temperature to a level that is comfortable for you while considering energy efficiency and avoiding excessive cooling that may lead to discomfort.
