Learning about how mechanical things work has always interested me. People call me strange because a lot of the things I want to know about are rather mundane. They find it especially strange because they see no practical benefit from learning the things I am curious about. However, I find learning to always be of some use or enjoyment, even if I can get no personal value out what I learned, such as with the process of lighting a light bulb. It’s not like understanding how photons are created, as a result of electrons bouncing off of electrons, is a vital piece of information that’s going to change my life. However, it does improve my understanding of how electricity works, and I find that quite fascinating. When I was learning about my HVAC system, I found out what HVAC stands for. First of all, I never realized HVAC was an acronym to begin with. If you didn’t catch it, the acronym stands for Heating, Ventilation, and Air Conditioning. I also never considered the process behind setting a specific temperature on my thermostat and getting the corresponding heat or cooling. However, as the acronym also suggests, the heating process is entirely separate from the cooling process. As for heating, a typical home will use either a furnace system or a boiler system. A furnace is a forced air system that uses fossil fuels to generate heat. A boiler uses hot water that travels through pipes to generate heat. Both of these systems have different means of heating. Whether it be a furnace or boiler, the heating part of an HVAC system delivers the heat you need to your home. Obviously, since cooling is the process of removing hot air, an air conditioner functions independently of the heating system in an entirely different process.
