Course Description:

Students will learn the concepts of the basic operations of various heating and cooling systems for commercial and residential applications. This course focuses on maintenance and service procedure for initial tuning of HVACR systems for energy efficiency. Practical application of skills include: taking pressures, identifying refrigerants, recovering and recycling refrigerant, evacuating and charging refrigeration systems. Also included are all applicable safety precautions and EPA governed environmental regulations. Energy efficiency will be emphasized.

Course Outcomes:

  1. Apply a basic understanding of the vapor-compression refrigeration cycle including refrigerant pressure/ temperature relationships, types of refrigerants, recovery and recycling, and evacuation and charging, in order to fine tune systems for maximum efficiency.
  2. Use safe work practices and observe EPA environmental regulations.
  3. Apply a basic understanding of natural gas and fuel-oil heating systems, including the combustion process, in order to fine tune heating systems for maximum efficiency.
  4. Adjust system controls to the manufacturers recommended settings in order to balance and fine tune HVAC/R systems for maximum efficiency.

Outcome Assessment Strategies:

  1. Intelitek on-line activities including end of section tests and final evaluation.
  2. Instructor generated evaluation including tests and projects.
  3. Hands on lab activities
  4. Hands on evaluation.
