What should the low pressure be for a 404a refrigerant on a freezer?
18-20psig suction 250-270 psig discharge In freezers pressures are ok .I got it ,but the mention pressure of suction 18-20 discharge 250-270 at what temprature in centegrade it should be.

what is suction pressure of r407a
Can R22 be used with 404A refrigerant?
No, refrigerants cannot be blended.
Could you mix 404a refrigerant with R12?
Mixing 404A refrigerant with R12 is not recommended, as they are incompatible and can lead to system damage, decreased efficiency, and safety hazards. R12 is a CFC refrigerant, while 404A is a blend of HFCs that operates at different pressures and thermodynamic properties. Additionally, mixing refrigerants can complicate recovery and recycling processes, making it difficult to maintain compliance with environmental regulations. It's best to use the specified refrigerant for your system.
What type of refrigerant do you need in a high temp walk in freezer?
Newer freezers compliant to efficiency standards use R-404a. However an older unit may only be able to us R-22 (which will be completely phased out by 2020).
Is r-404a compatible with 134a?
R-404A and R-134a are not compatible for use in the same system. R-404A is a blend of refrigerants, primarily used in low-temperature applications, while R-134a is a single-component refrigerant commonly used in medium-temperature applications. Mixing them can lead to reduced efficiency, system damage, and operational issues. Always consult manufacturer guidelines and refrigerant compatibility charts before making any changes to refrigerant types.
Will 404a mix or use the same system as r12?
R-404A is not compatible with R-12 systems due to differences in chemical composition and operating pressures. While R-404A is a hydrofluorocarbon (HFC) refrigerant, R-12 is a chlorofluorocarbon (CFC), and their properties require distinct system components. Converting an R-12 system to use R-404A typically involves replacing the compressor, expansion valve, and other components to ensure proper functionality and efficiency. Always consult a qualified technician for refrigerant conversions.
What should the high and low pressures be for 404A refrigerant on a walk in cooler?
The recommended high pressure for 404A refrigerant in a walk-in cooler is around 250-300 psi, while the low pressure should be around 50-65 psi. These values may vary depending on factors such as the ambient temperature and the specific system design. It's important to consult the equipment manufacturer's guidelines for precise pressure recommendations.
Can you mix 404a with 410a?
Mixing refrigerants 404A and 410A is not recommended. Each refrigerant has a different composition and pressure characteristics, which can lead to system inefficiencies, potential damage, and safety hazards. Additionally, mixing refrigerants can violate environmental regulations and void equipment warranties. It's best to use the specified refrigerant for your system to ensure optimal performance and compliance.
