Title: Detect non-condensables, using the pressure and temperature relationship (i.e., the P/T chart).
Course: Heating, Ventilation, Air Conditioning, and Refrigeration II (17056-II) > Section: Complying with EPA Laws and Regulations

Detection should include using the gauge set and pressure temperature chart to identify the refrigerants and non-condensables.

Process/Skill Questions:

- What indicates that there are non-condensables in the tank of refrigerant?
- What is a non-condensable?
- How are non-condensables prevented from entering the recovery cylinders?
- How does Boyle’s law apply to non-condensable gasses?
