if room tem is 70f 15psi
frezer not frezing hi side 250 psi low side 45 psi
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
No, refrigerants cannot be blended.
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.
The boiling temperature of refrigerant R-404A at atmospheric pressure is approximately -46.5 degrees Celsius (-51.7 degrees Fahrenheit). However, this temperature can vary slightly depending on the specific pressure conditions in the system. R-404A is commonly used in refrigeration applications, particularly for low and medium-temperature systems.
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).
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.
For R-404A refrigerant in an ice maker, the typical high side pressure should range from about 200 to 250 psi, while the low side pressure generally falls between 30 to 40 psi, depending on the ambient conditions and specific system design. It's important to consult the manufacturer's specifications for precise values, as they can vary based on the unit's configuration and operating conditions. Always ensure proper refrigerant management and monitoring for optimal performance.
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.
