Before we convert temperature scales, let's take a step back and think about what temperature is in the first place. Temperature is proportional to the average kinetic energy of the random microscopic motions of the constituent microscopic particles, such as electrons, atoms, and molecules. Translation: Temperature is the average “movement energy” of the molecules in […]

Every HVAC/R tech needs an electronic leak detector nowadays, and with low-GWP HFC and HFO refrigerants getting more and more commonplace, every HVAC/R tech needs a VERY sensitive electronic leak detector. (Yes, electronic leak detection does work.) We often see three types, but let's toss out the corona discharge leak detector right off the top. […]

Oxidation is the loss of electrons, reduction is the gain of electrons, and the reaction is what occurs between the two. When we talk about chemistry or chemical reactions, we are really talking about an electrical interaction between molecules seeking equilibrium. In other the words, the old “high voltage goes to low voltage” rule applies […]
