Course Title: A2L Refrigerants: Characteristics and Applications
Delivery Method: Live Online
Course Description: This six-hour course examines the characteristics, standards, and applications of A2L refrigerants, focusing on their integration into modern HVAC systems. The course discusses the evolution of refrigerants, the efficiency differences between R410A, R32, and R454B, and how A2L refrigerants are addressed in codes and standards. The course also provides guidance for installing and servicing A2L equipment to mitigate flammability risks and ensure safe operation.
Learning Objectives:
Learning Objective 1:
Learners will be able to define A2L refrigerants and the meaning of “mildly flammable” and identify the differences between A2L and A3 refrigerants.
Learning Objective 2:
