Transcription

1 Purpose Statement Business and industry are creating a growing demand for trained technicians in the field of air conditioning, heating and refrigeration. This program is designed to prepare a student for full-time entry-level employment immediately upon completion of the program Air Conditioning Diploma Ronnie Cole and Larry Wallace Print Unit Plans Unit Planning Home 1 : Student Learning Students are able to understand and troubleshoot electrical diagrams for HVAC and wiring up various HVAC units used for training in the lab both serial, parallel, and series-parallel system circuits Final Exam, Lab skills training using hands on training boards trainers. AIR 134, AIR 135. Air 134 students should be able to wire up a simple ac and heating unit by the end of the course with zero mistakes and test out on final test with a over all average of 88% and 100% with Hands On testing. AIR 135 students should be able to wire up a Heat pump system both the heating and cooling side of the system by the end of the course with zero mistakes and test out on final test with a over all average of 88% and 100% with Hands On testing Students averaged 88% pass rate on AIR 134 written test and 95% hands-on success rate on the hands on electrical control trainer. Students averaged 88% pass rate on 1 of 10 8/9/16, 3:20 PM

2 AIR 135 written test and 100% hands-on the hands on trainers control. There were approximately 13 students in night classes. Also had DHE-1 students a total of 6 students with the information the same as above. Students demonstrated strong abilities to understand & troubleshoot basic electrical components in AIR 134. An electrical hands on trainers circuit board trainers that was added to AIR135. Students were required to build, install, and operate a circuit trainer using HVAC components. This trainer simulated the electronic circuitry on an HVAC system both heating,cooling systems and heat pump systems. Students had some problem in understanding the electrical layout of the heat pump system and basis air condition system at first but got better by the end of the course. To help with the problem the teacher should have more electrical hands on training and blue print reading throughout the course both AIR 134 and AIR 135. This will help students to better understand the electrical part when wiring up the systems. Also had DHE-1 students a total of 6 students with the information the same as above. 10 : Student Learning Students enrolled in Air Conditioning will be able to demonstrate hands on using trainers both Gas and Oil type with equipment/trainers at 90% accuracy. will be measured by a final exam and skills test on both oil and Gas. which will be starting up both the oil and gas trainers after trouble shooting the systems to find the problems with each system a passing rate of 85% or more. Final written test with a passing score of 88% or better. and a over all class average of 90% Students averaged 89.5% pass rate on written test through out the course. Students averaged 88% hands-on success rate through out the course. With final grades for students as a hold averaged 90% or better on both hands on and testing. 2 of 10 8/9/16, 3:20 PM
