What are the advantages of using refrigerant blends over single-component refrigerants?

Refrigerant blends offer several advantages over single-component refrigerants, including improved thermodynamic efficiency, enhanced safety, and reduced environmental impact. By combining different refrigerants, blends can achieve a balance of properties that may not be possible with a single component. For example, a blend may exhibit higher efficiency than a single refrigerant while still meeting safety and environmental standards. Additionally, blends can be designed to be more cost-effective than single-component refrigerants.
