How does R-449A compare to R-404A?
R-449A has a similar cooling capacity with improved energy efficiency compared to R‑404A. In many cases the compressor discharge temperature will not be a concern but for some low temperature applications, under the same operating conditions, R‑449A will exhibit a significantly higher compressor discharge temperature than R‑404A which, in a retrofit situation, may need to be managed.
Full theoretical performance comparisons at customer specified conditions are available from Climalife on request.
