Built for technicians who need practical troubleshooting skills, not design theory. This course covers refrigeration cycle fundamentals, psychrometrics basics, and hands-on CRAC/CRAH diagnostics — the skills you use during an actual cooling failure, not just a scheduled inspection.
You'll work through common failure modes, airflow measurement techniques, and a preventive maintenance schedule you can apply immediately, plus emergency troubleshooting procedures for when cooling capacity drops unexpectedly.
What You'll Learn
- Diagnose common CRAC/CRAH failure modes quickly and accurately
- Apply refrigeration cycle fundamentals to real troubleshooting scenarios
- Measure airflow correctly to identify cooling distribution problems
- Build a preventive maintenance schedule that reduces emergency callouts
