why is it colder when the air conditioner is at 23 degrees than compared to when the weather app says it’s 23 degrees out ?
In: Physics
There’s several factors, conditioned air is often drier than outside air, and humidity plays a major part in “feels like” temperature. As well, you might just be noticing that it’s cold inside when you’re not wearing all the clothes you might be wearing if you were outside. Then, there’s also the fact that you might be more used to hotter temperatures when you set your AC, making the relatively cooler 23 seem colder than it might otherwise feel.
If you are receiving direct sunlight you will be warmer than the air temperature. Forecasts and weather stations measurements use shade temperatures.
One thing not mentioned by others is the placement of the thermostat. The AC is controlled by the temperature at the thermostat. The temperature in different rooms may differ colder or hotter depending on air circulation, but theAC switches off/on based on the temperature only at the thermostat.
For example, our thermostat is on the main floor of the house, we have a specific room that is always a couple degrees colder if the AC is on and a couple degrees hotter if the furnace is on.
