Coil SHR, Ventilation, and Bypass Factor – Advanced Psychrometrics Part 2
This is the second article in a three-part series, where Advanced Psychrometrics are explored. The source material for each of the articles in this series is ACCA Manual P Sections 3, 4, and 5. This article is based on information found in Section 4. If you followed the previous Advanced Psychrometrics article, you now know […]

Sensible Heat Ratio (SHR)
Every piece of air conditioning equipment is capable of moving 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 towards changing vapor water in the air into water that collects […]

Sensible Heat in Air and Water
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 […]

Calculating Target Delta T w/ Manufacturers’ Data
This tip was a COMMENT on the sensible heat ratio tip left by Jim Bergmann. As usual, Jim makes a great point; once you get the “sensible” capacity for a piece of equipment at a set of conditions, you can easily calculate a true target delta T. Another interesting thing you can do is use […]
