HVAC 103 - Advanced Refrigeration and Air Conditioning
This course provides students with a background and understanding of commercial refrigeration design installation and service. The course materials also address troubleshooting techniques of components with special emphasis on refrigerant control devices, compressors, reducing valves and dryers. Air conditioning fundamentals covered include psychrometer, air flow and duct sizing. Superheat and sub cooling adjustments for both refrigeration and air conditioning are covered. The math necessary to perform the calculations in this course is covered as an integral part of instruction.
Upon successful completion of this course, students should be able to:
- Explain heat flow, change-of-state condensing point, evaporation point and laws of refrigeration.
- Describe the types of commercial refrigeration systems and identify integral components.
- Cite common problems with expansion valves, pressure reducing valves, pressure switches, filters and dryers.
- Adjust the superheat and sub cooling of a refrigeration machine for maximum efficiency.
- Depict a psychrometric chart and understand its use in air conditioning.
- Measure air flow and discuss common problems associated with air side residential and commercial air conditioning.
