While I can provide general information, it's important to consult with a qualified HVAC professional for specific guidance regarding refrigerant replacement in your split-type air conditioner.
R32 and R410A are both commonly used refrigerants in modern air conditioning systems, but they are not interchangeable. R32 (difluoromethane) and R410A (a blend of difluoromethane and pentafluoroethane) have different properties and operating pressures, and their use is specific to the system designed for them.
The compatibility of refrigerants depends on several factors, including the design and components of the air conditioning system. Manufacturers design units to work with specific refrigerants, and using a different refrigerant can have adverse effects on the system's performance, efficiency, and safety.
Replacing the refrigerant in your system with a different one, such as using R410A instead of R32, is generally not recommended unless it is explicitly stated by the manufacturer and the system is designed to accommodate the alternative refrigerant. Mixing refrigerants or using an incompatible refrigerant can damage the system, reduce its efficiency, and potentially create safety hazards.
If R32 is not available in your country, it is best to consult with an HVAC professional or contact the manufacturer of your air conditioning unit for guidance. They can provide specific recommendations for your system and suggest any available alternatives that are compatible and safe to use. It's crucial to ensure that any refrigerant replacement is done by a qualified technician following the appropriate procedures and guidelines.
