This class covers the changes made during the 2015-2018 code review cycle to two “core” chapters of the 2018 International Mechanical Code® (IMC) - Chapter 3 on General Regulations and Chapter 4 on Ventilation – that are basic to all HVAC tasks. This is followed by some of the most varied and challenging codes in the 2018 IMC including those regarding fireplaces, pressurized hot water vessels, refrigeration, hydronic heating, and fuel oil systems. The class finishes with an in-depth look at the emerging technology of HVAC and electrical power generation from heat transfer fluids that absorb solar radiation for use within the structure. Chapter 14 has been heavily revised for 2018 and offers new opportunities for “green” HVAC.
Each change in this class is presented in a “cut-and-paste” format with any deletions and additions from the 2015 IMC clearly shown. Each change is then discussed for the reason it was made and how it impacts a working HVAC contractor or technician, based in part on the proceedings of the ICC Technical Committees.
