Mixing NU22 (a refrigerant blend) with R22 is not recommended, as it can lead to system inefficiencies and potential damage. NU22 is designed as a replacement for R22 but has different properties, which can affect lubrication and pressure characteristics. Additionally, blending refrigerants can complicate recovery and recycling processes, making it difficult to comply with environmental regulations. It's best to fully evacuate the system and use the appropriate refrigerant specified for your application.
