In this episode of CO2 Experts, we’re shifting from advanced technical concepts back to the foundational principles of CO2 refrigeration by diving into basic keywords and terminologies. We cover entropy diagrams, saturated lines, subcooling, and the critical point, as well as plotting system parameters to troubleshoot more effectively. We’ll also discuss differences between global terminologies and give refrigeration technicians practical tips for mastering transcritical CO2 refrigeration systems.

In this episode, we cover:

-CO2 refrigeration keywords and terminologies

-The entropy diagram

-Saturated points and vapor states

-Flash gas and system dynamics

-Critical points and supercritical fluids

-CO2 safety

-Plotting and troubleshooting CO2 systems

-CO2 system design strategies
