A2L & HVAC
Event Details
Refrigerant Cycle / Superheat and Subcooling
This course provides a foundational understanding of the HVAC Refrigerant Cycle, emphasizing the principles and components essential to efficient heating, ventilation, and air conditioning systems. Key topics include the refrigerant cycle (compression, condensation, expansion, and evaporation), the concepts of superheat and subcooling, and their critical roles in system performance and diagnostics. Students will gain practical skills in analyzing system operations, measuring superheat and subcool values, and optimizing system efficiency. Designed for beginners and HVAC technicians seeking to enhance their technical expertise, this course blends theoretical knowledge with hands-on applications.
Low GWP / A2L Refrigerants
This course provides an overview of A2L refrigerants, a category of low-flammability refrigerants widely regarded as the next generation of solutions for meeting global environmental regulations. Participants will explore the characteristics of A2L refrigerants, including their thermodynamic properties, safety classifications, and environmental benefits. The course also delves into the upcoming industry trends, such as new standards, equipment design considerations, and the transition timeline from high-GWP (Global Warming Potential) refrigerants to A2L alternatives.
Key topics include:
- Characteristics of A2L Refrigerants: Understanding low-GWP performance, mild flammability (ASHRAE Standard 34), and safety handling requirements.
- Regulatory and Environmental Drivers: The impact of global mandates, such as the Kigali Amendment, F-Gas regulations, and phase-down schedules.
- Upcoming Innovations: Equipment compatibility, new technologies, and challenges in adoption.
- Safety and Risk Management: Best practices for storage, transportation, and maintenance, as well as compliance with updated safety standards.
