In this episode of HVAC TV, we sit down with Vic Marinich from Danfoss to talk all things heat exchangers—what they are, why they matter, and how they’re evolving to meet the demands of modern HVAC systems.

From chillers and data centers to river water cooling and refrigerant challenges, Vic breaks it all down in a way that's practical and easy to follow—even if it's been a while since you’ve calculated Reynolds numbers (don’t worry, we don’t go there).

In the finale of JADEC: The Tour, Tony Mormino and Rob Tanner step inside YORK’s Air Handler Lab and the massive reverberant sound chamber — where fans and air handlers are pushed to the limits of airflow, static pressure, and sound power. From a 100,000 CFM test system to the precision of accredited sound measurements, this episode reveals how Johnson Controls engineers ensure performance and reliability in the real world.

In Part 7 of the JADEC Tour, Rob Tanner and Tony Mormino dig into one of YORK’s latest innovations — the R8 compressor. Built to offset capacity losses from the transition to low-GWP refrigerants, this open-drive centrifugal design helps deliver up to 3,000 tons of cooling with an added efficiency boost from a unique economizer cycle. You’ll hear how this innovation came to life in JADEC’s labs, what it means for YORK’s YK product line, and why even a few percentage points of efficiency can change the game in large-tonnage chillers.
