The refrigerant pressure in a split air conditioner (split AC) can vary depending on the operating conditions and the specific type of refrigerant used. However, I can provide you with a general guideline for typical pressure ranges for a split AC system using common refrigerants like R-410A, which is commonly used in modern split ACs.
Please note that refrigerant pressures can be influenced by factors such as indoor and outdoor temperatures, the load on the AC (cooling or heating demand), and the condition of the AC system. Refrigerant pressures are typically measured in pounds per square inch gauge (PSIG). Here are approximate pressure ranges for R-410A in a split AC:
How Much Gas Pressure in Split AC
- Suction Pressure (Low Side): This is the pressure on the low-pressure side of the system, which is between the indoor evaporator coil and the compressor. During normal operation, the suction pressure for R-410A can range from approximately 70 PSIG to 130 PSIG, depending on operating conditions.
- Discharge Pressure (High Side): This is the pressure on the high-pressure side of the system, which is between the compressor and the outdoor condenser coil. The discharge pressure for R-410A can range from approximately 250 PSIG to 450 PSIG under normal operating conditions.
Please keep in mind that these pressure ranges are approximate and can vary based on factors such as the specific AC system design, the manufacturer’s recommendations, and the outdoor and indoor conditions. Refrigerant pressures should be measured and adjusted by trained HVAC technicians during installation, maintenance, and troubleshooting.
If you suspect any issues with your split AC system or need to check refrigerant pressures, it’s best to consult a qualified HVAC technician who has the tools and knowledge to perform proper diagnostics and service. Incorrect refrigerant pressure levels can affect the performance and efficiency of the AC system.
