In Part 2 of this episode of the HVAC Know It All Podcast, host Gary McCreadie is joined by Jamie Kitchen, an HVAC expert, Training and Account Manager at Danfoss. They discuss the world of TT valves for heat pumps, particularly the Danfoss TR6. Jamie explains how balance port valves work, the importance of proper leak detection, and why correct charging practices are crucial for efficiency. He also talks about the challenges with condensing pressures and why new technology is improving system reliability. Jamie’s insights help technicians avoid common mistakes and enhance system performance.

Jamie Kitchen talks about how balanced port valves help HVAC systems maintain steady pressure, especially during temperature changes. He explains why proper leak detection and charging techniques are key to avoiding equipment damage. Gary and Jamie discuss the importance of keeping condensing pressures stable to ensure the system runs efficiently. Jamie also shares how modern technology, like a variable-speed fan, helps solve old issues with air conditioning systems. They both agree that precision in setup and maintenance is essential for long-term reliability.

Jamie explains that TT valves, like the Danfoss TR6, help HVAC systems maintain stable pressure, especially when conditions change. He says proper leak detection and accurate charging are vital for preventing damage to compressors. Gary notes that modern systems have new tech, like variable-speed fans, to keep pressures steady. They both agree that many older methods are inefficient or can cause issues, but balancing port valves and precision in maintenance make a big difference in system performance and longevity.
