How Do You Ramp Up Your Team to Effectively Service and Support CO2 Applications?

HVAC School - For Techs, By Techs

In this informative episode, Bryan Orr speaks with Andre Patenaude from Copeland about CO2 refrigeration systems. They dive deep into the unique characteristics and challenges of working with CO2 as a refrigerant, providing valuable insights for HVAC and refrigeration professionals looking to expand their knowledge in this growing field.

Andre explains the reasons behind the increasing adoption of CO2 systems, including regulatory pressures and environmental benefits. He details the peculiarities of CO2 refrigerant, such as its high triple point and lower critical point, which create unique operating conditions not seen in traditional refrigerants. The conversation covers the concept of transcritical operation and how it affects system design and efficiency.

The discussion then shifts to the infrastructure of CO2 systems, focusing on the transcritical booster architecture commonly used in supermarket applications. Andre breaks down the components and operation of these systems, highlighting key differences from traditional setups. He also touches on the latest innovations in compressor technology from Copeland, including new designs specifically engineered for CO2's high-pressure applications.
