In this episode of the HVAC Know It All Podcast, host Gary McCreadie welcomes Joshua Souders from Copeland for the second part of their conversation about advanced compressor technology. Josh brings his deep knowledge of HVAC systems to the table, focusing on variable-speed compressors, vapor injection, and how these innovations are changing the game for heat pumps.

They dive into topics like how variable-speed compressors work, the challenges of oil delivery, and why vapor injection is key to making heat pumps effective in extremely cold climates. They also tackle common misconceptions about heat pump performance in freezing temperatures and discuss the DOE Cold Climate Heat Pump Challenge. If you’re in the HVAC industry, this is an episode you don’t want to miss.

Expect to Learn:

How Variable-Speed Compressors Operate: A clear breakdown of how these compressors adjust to meet heating and cooling demands while boosting efficiency.

The Benefits of Vapor Injection: An explanation of how this technology improves heating capacity and efficiency, especially in colder climates.

Advancements in Heat Pumps: Insights into how today’s heat pumps are designed to perform well, even in extreme cold weather.

Debunking Heat Pump Myths: Addressing the outdated belief that heat pumps can’t function effectively in freezing temperatures.

Practical HVAC Knowledge: Useful advice on understanding, maintaining, and selecting compressors for optimal performance.
