Lower-GWP Refrigerant Transition
Why environmental rules and equipment technology are changing refrigerant choices.

What this topic covers
Why environmental rules and equipment technology are changing refrigerant choices.
Core thermal ideas
Refrigerant transitions can affect pressure, flammability, equipment compatibility and service practices.
Acceptability varies by end use and jurisdiction and changes over time.
Existing equipment should not be converted based on generic web guidance.
System tradeoffs
Energy, water, refrigerant leakage and reliability can trade off against one another.
What to monitor
Weather and production load should be considered when comparing performance across time.
Lifecycle perspective
Optimization should reduce total resource use while maintaining required process temperatures and resilience.
