Because low-pressure chillers operate under a vacuum, ambient air and moisture can leak inward. Purge units are installed to separate and exhaust these non-condensables from the refrigerant circuit. Essential Study Strategies for the 9th Edition V2 Hydrostatic tube tests are utilized to check for

Dissecting the differences between CFCs, HCFCs, HFCs, and HFOs, alongside their respective Ozone Depletion Potential (ODP) and Global Warming Potential (GWP).

The "9th Edition V2" (Version 2) represents the most current update, reflecting that HVACR technicians must observe to be in compliance with the most recent changes and additions to EPA guidelines.

The foundational chapter of the 9th Edition V2 manual centers on atmospheric protection and federal laws. Stratospheric Ozone Depletion The Core Section The chemical mechanics of how

V2 places a massive emphasis on next-generation, mildly flammable refrigerants known as A2L refrigerants (such as R-32 and R-454B). Technicians must understand the specific safety, storage, and handling protocols for these low-GWP alternatives.

This section certifies technicians to service small, hermetically sealed systems containing 5 pounds or less of refrigerant.
