Ease of adoption: It’s designed to be as close as possible in thermodynamic behavior to R-410A so that systems can be adapted / designed with minimal changes. In many cases, manufacturers view it as “drop-in alternative for new systems” with certain modifications (safety, component compatibility) considered.
