Hvac School - For Techs, By Techs

Collin Olson, the staff physicist of The Energy Conservatory (TEC), joins Eric Kaiser at AHR 2022 to talk a bit about data logging. Data logging refers to the act of using sensors to record data over time and then analyzing that data. TEC dipped its toes into data logging with the APT and then TECLOG. Data logging allows us to take and store multiple readings as well as extrapolate data into graphs, making it easier to analyze performance. The TECLOG4 software is the most up-to-date version. TECLOG is a simple software to use with basic training. The understanding of building science continues over a lifetime, but the actual software can be learned in approximately 30 minutes. TECLOG is free with TEC’s hardware, such as the DG-1000. To get started, all you need is a precision manometer and a computer. However, it’s worth nothing that the DG-1000 stores a lot of data, meaning that you can launch data logging sessions on the gauge without your computer. Some of the most important measurements are related to dra
