DESCRIPTION:

This course is designed for persons interested in entering the refrigeration/air conditioning service, installation or building maintenance fields and is intended for the intermediate level student.  The course is oriented toward development of basic skills required in troubleshooting, repair, and maintenance of refrigeration/air conditioning systems.  Topics covered are soldering, silver soldering, service and troubleshooting tools and systems construction.

OBJECTIVES:

1. Build a refrigeration system according to industry and EPA standards. the tools and procedures used in the industry.

1. To provide the student with an opportunity to develop entry level competency in the basic skills

and troubleshooting procedures needed in the industry.

1. To test and document the students level of competency, by performance.

Outcomes:

Students will demonstrate the ability to systematically assemble a refrigeration system.  Students will demonstrate the ability to apply a systematic approach to troubleshooting, repair, and maintenance of refrigeration systems

Students will demonstrate the ability to select and use appropriate tools and equipment for the assembly,   troubleshooting, repair, and maintenance of refrigeration systems.

ADA

Students who feel they may need an accommodation based on the impact of a disability are encouraged to meet privately with their instructors to discuss their specific needs and must contact the Disability Resource Center (DRC) in RDMT 114 (or call 775-673-7277) to establish documentation of a disability and to coordinate reasonable accommodations.

NOTE: Special attention is directed to appendices

COURSE OUTLINE

This course is self paced in that performance testing is done as the individual student feels ready. However most classes will start with a short lecture that is specific to one of the skills or is informational in nature.

The course will proceed in the following order.

1. Copper tubing. (informational)
2. Cutting and bending copper tubing.
3. Flaring copper tube.
4. Swaging copper tube.
5. Soldering and brazing copper tube.
6. Use of gauge manifold.
7. Refrigerant recovery and recycling.
8. Leak testing refrigeration systems.
9. Evacuation of refrigeration systems.
10. Charging refrigeration systems.
11. Fundamental troubleshooting principals.
12. Electrical test meters.
13. Troubleshooting control circuits.
14. Troubleshooting motors and compressors.(electrical) and other electro/mechanical devices.

Hands-on instruction, practice, performance testing and written

quiz’s are included on all items listed above with the exception of those shown as (informational).

EPA 608 Certification. We can help with that. We have study guides. Plus on the text book page, they practice exams that you take for free.  The cost of taking the exam is 15.00 Dollars. If you have questions or need help see one of the instructors
