Heat Pumps / Comfort and Electrification w/ Copeland

In this informative episode, Josh Souders from Copeland joins Bryan to dive deep into heat pump technology, discussing everything from basic operations to advanced features in cold climate applications. The conversation begins with a fundamental explanation of how heat pumps work, describing them as essentially air conditioners with a reversing valve that allows them to provide both heating and cooling. Josh explains the thermodynamic principles that enable heat pumps to extract heat from cold outdoor air and transfer it indoors, achieving coefficients of performance (COP) ranging from 1.5 to 3, making them significantly more efficient than traditional electric resistance heating.

The discussion moves into the broader context of electrification and decarbonization, explaining how heat pumps fit into these environmental initiatives. Josh details how modern cold climate heat pumps have evolved significantly from earlier generations, particularly through the Department of Energy's Cold Climate Heat Pump Challenge program. This program pushed manufacturers to develop systems capable of maintaining full heating capacity at very low temperatures, addressing historical concerns about heat pump performance in cold regions.

Variable speed technology emerges as a key topic, with Josh explaining how modern inverter-driven compressors can operate across a wide range of speeds - from 900 to 7,000 RPM in their newest A2L products. This capability allows systems to maintain heating capacity in cold weather by increasing compressor speed when needed. The conversation also covers practical considerations for installation and troubleshooting, including the importance of proper defrost cycles, installation location, and the use of riser kits in snowy regions.
