This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: • How direct emissions are calculated using refrigerant mass and global warming potential • How supplied energy and leakage data determine which emissions source dominates • How poor heat-transfer conditions increase compressor head pressure and energy draw • Key regulatory distinctions between Great Britain, Northern Ireland, and the European Union • Why zero ozone depletion potential does not equate to zero global warming impact This independent prep episode helps you master theoretical concepts for the City & Guilds 2079 Category I knowledge assessment.
