IMR 4100 - Pressure & Temp Relations


Clock Hours: 12

Delivery Mode
on-ground

Course Description:
Students learn the principles of how refrigerants react to pressure and temperature changes at different points of matter. Students will use a pressure temperature chart to determine the state of matter of a refrigerant at each point in the refrigeration cycle. Students will calculate the refrigerants superheat and subcooling from the pressures and temperature readings obtained on specific equipment. 

Student Learning Outcomes:
Students will attain the necessary skills to be able to:

  1. Discuss Pressure Temperature Relation chart and its purpose for Diagnostics
  2. Discuss PT Chart and its use in calculating superheat
  3. Discuss PT Chart and its use in calculating Subcooling
  4. Explain PT Gauge Readings that indicate Low Charge.
  5. Explain PT Gauge Readings that indicate Over Charge.
  6. Explain Normal Operating conditions for Pressure Temperature relationships
  7. Demonstrate how to take Pressure and Temperature readings to determine a refrigeration systems operating parameters
