With the growing global emphasis on environmental protection and energy efficiency, traditional refrigerants with high Global Warming Potential (GWP) are being gradually replaced by more eco-friendly alternatives. R513A, as one of the leading options, stands out for its low GWP and excellent performance, making it widely used across various refrigeration systems. This article provides a detailed introduction to R513A’s features, applications, key parameters, and environmental benefits.
Introduction to R513A Refrigerant
 |
R513A is an eco-friendly, non-ozone-depleting refrigerant composed of a blend of HFO-1234yf and HFC-134a. With a GWP value ranging from 465 to 675โsignificantly lower than R134a’s 1430โand an Ozone Depletion Potential (ODP) of 0, R513A ensures minimal environmental impact. It was specifically designed to serve as a high-performance alternative for systems currently using R134a, offering an ideal balance of efficiency and sustainability. |
