As the HVACR industry continues to move forward and innovate, the refrigerants that were once so commonplace are now being phased out. Replacing them are more energy efficient, environmentally friendlier refrigerants, known as Low GWP refrigerants. Many of these new refrigerants are classified by ASHRAE as A2L, or slightly flammable. The industry is also seeing expanded use of some hydrocarbon (A3) refrigerants, such as propane and isobutane. Students and technicians will require additional training for the safe handling and transportation of these refrigerants.
This course provides students and practicing technicians with the information and knowledge necessary to safely handle mildly flammable refrigerants as well as prepare for the ESCO Institute's Low GWP Refrigerant Safety certification exam.
Main topics include:
Introduction to Low GWP refrigerants
Refrigerant properties and characteristics
The refrigeration cycle
Working with refrigerant blends
Proper installation and service guidelines
Flammable refrigerant considerations
Explanation of associated codes & standards for A2L refrigerants
Individuals completing this course will be prepared for ESCO Institute's Low GWP Refrigerant Safety Certification exam. Note: certification exam is separate and not included in the course.
