Gathering System Data for Use

When collecting real world data to analyze system performance nothing beats a good old fashioned pencil and paper.
You can use a form to keep it organized, or just a list if that works for you. Below I provided a pictogram for up to three stage system.

This can be used for up to three stage refrigeration cycle by marking N/A (not applicable) if the system doesn’t have a particular feature.
The PRESS is short for pressure, and TEMP is short for temperature. WB and DB, are wet bulb and dry bulb temperatures of the air entering and leaving the evaporator.
Each valve has an O or C beside it to indicate whether it’s open or closed.
I’ve posted the Excel file so it can be printed on one page or altered to meet your needs.
Hope you find it helpful!
