DO YOU WANT TO BREATHE FRESH AIR EVEN WHEN INDOORS?
There is a basic scientific principle that HOT AIR RISES and COLD AIR SINKS.
Yes, hot air rises – but to say that it’s the heat’s natural state to want to rise would be wrong. It can move in any direction. Basically, heat travels from an area of higher temperature to a lower temperature.
In scientific terms, this is known as the law of thermodynamics. According to the second law of thermodynamics, heat transfer can occur through convection, conduction, and radiation.
The air exchange between inside and outside air is driven by two forces. One is commonly known as the chimney effect or the stack effect. As hot air rises, it moves outside to the top of your home, and the colder outside air is drawn in from the bottom through gaps, leaks, and windows, etc.
