Let's first state the obvious. Most techs are intimidated by psychrometric charts and Mollier diagrams. We JUST ARE. While there are some pretty complicated formulas that back up these diagrams, using them isn't that big of a deal once you understand the different elements and then focus on one at a time.

Here is another great explanation from Michael Housh of Housh Home Energy in Ohio. Thanks, Michael! I’m going to lay out and compare the sensible heat rate equations for both the air-side and water-side of HVAC to help draw similarities and dive deeper into the science behind these equations. This is the beginning of a […]

Every piece of air conditioning equipment can move a certain amount of heat BTUs (British Thermal Units) at set conditions. In most cases, during the cooling mode, a portion of those BTUs will go toward changing the temperature of the air, and a part will go toward changing vapor water in the air into water […]
