<p>To help keep track of compressor health, I wrote a program to look at all of the Compressor 2's on-off cycles to get a baseline on how the compressor "saw-tooth" pattern should look with respect to timing.</p><p>Data was looked at for the RICH cooling system's buffer tank from 2019-10-09 10:28:10 to 2019-10-10 09:59:10 (23.52 hours).</p><p> </p><p>Time between compressor starting a cycle to the start of the next cycle:</p><p>Average cycle time = 23.62 +/- 1.76 min</p><p>Max cycle time = 29.48 min</p><p>Min cycle time = 20.6 min</p><p> </p><p>Time Compressor is running during cycle:</p><p>Average time on = 20.89 +/- 1.66 min</p><p>Max time on = 25.92 min</p><p>Min time on = 18.27 min</p><p> </p><p>Time Compressor is NOT running during cycle:</p><p>Average time off = 2.73 +/- 0.54 min</p><p>Max time off = 4.01 min</p><p>Min time off = 1.98 min</p><p> </p><p>Duty Cycle [% of cycle the compressor is running]:</p><p>88.46 %</p>
