Our most challenging task as air conditioning engineers is understanding and controlling humidity. Willis Carrer, the father of air conditioning, invented the first air conditioning in 1902 to dehumidify the air in a publishing factory and published the first document on psychrometrics. It's so complicated that his peers responded, "Whatcha talkin' bout Willis?!?" The basic understanding in Ohio is that it is dry in the winter and humid in the summer, but all people relate to is relative humidity. Well, relative humidity is relative. On our peak summer day, when the temperature is 91°F, the relative humidity is about 42%RH. In the winter, when it is 0°F, the relative humidity is about 50%RH. The month with the highest relative humidity is December, with an average relative humidity of 74%RH. To that, I say, "Whatcha talkin' bout Willis?!?" If you lower the thermostat in a room in your building from 75°F to 70°F, you can increase the relative humidity from 50%RH to 60%RH. If this intrigues you (which it shouldn't) and you want to know more (which would be weird), reach out, and I will coach you through the thrilling world of psychrometrics.
