Hello all, I finished the coarse today, and i gotta say that i had a good week! It was a good group of guys and it seemed like a shame to say goodbye, The team work aspect forced me to work with different students during different excersizes!
The instructors made the lab portion of the course seem as close to a real work experience as possible! They took the role of the supervisor on the job and were not over bearing with intervention unless they recognized that the team was veering into left field! sometimes they would let you make a mistake to reinforce some not so common sense operating principles, we learn best from our mistakes!
We worked with three different systems and did repetitive exercises in this order:
1. Walked down system with P&ID for valve tags and to id special function valves and components.
2. Filled out a partial valve worksheet that identified valve number, valve type, location relative to components,type of line, Comment related to function and normally open/normally closed.
3. Verify valve positions against valve worksheet.
4. Create start-up checklist for particular system.
5. Instructor verifies check list and/or corrects checklist
6. Start system to the point of normal operating parameters.
7. Load calculation worksheet.
8. Stabilize system
9. Non condensable worksheet.
10. Energy consumption worksheet.
And the two stage system included a soft start/soft stop hot gas defrost valve group id worksheet and an oil cooling comparison worksheet between the high stage and low stage compressors!
Overall it is the best class i have taken so far! I have been in this trade about 14 month's. There is a test and this is a pass or fail course! They offer the RETA CARO exam on friday, but word to the wise, i think this test may have been written by some backwoods clan in west virginia with an affinity for torture:confused:! As a matter
of fact the RETA test was my worst experience, i did pass though!
