BOOK A CALL with Trevor to learn more about refrigeration training programs

In this conversation, we’re covering the basics of heat transfer in refrigeration with Tania Herrera, Product Engineer at Güntner US. Heat transfer fundamentals are so important to know as a refrigeration technician, designer, or engineer. This episode dives into the mechanics of heat transfer, and how different factors such as refrigerant velocity, air flow, and material properties impact the efficiency and performance of heat exchangers, especially in CO2 systems operating in transcritical and subcritical modes. This is Part 2 of my series with Güntner - you can download Part 1 here: Episode 229. CO2 System Controllers with William Anaya of Güntner

In this conversation, we discuss:

-Fundamentals and mechanisms of heat transfer

-Latent and sensible heat

-Heat exchanger design principles

-3 types of heat transfer: conduction, convection and radiation

-Internal and external heat transfer

-Important heat transfer calculations

-Parallel flow and counter flow

-How to improve heat exchange within a heat exchanger

-Heat transfer in CO2 Systems and Gas Coolers
