  1. Explain the basic physics of the refrigeration cycle.
  2. Describe how the evolution from a traditional A/C system to heat pumps and then further to heat recovery resulted in reduced energy used for heating and cooling buildings. 
  3. Describe the basic naming, classification, and attributes of commonly used and new refrigerants.
  4. Explain why electrifying buildings will reduce carbon emissions and the important role that heat pumps play.
