what is suction pressure of r407a
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.
No, refrigerants cannot be blended.
The refrigerant pressure on an ice machine using R-404A refrigerant should typically be around 175-250 psi on the low side and 250-350 psi on the high side, depending on factors such as ambient temperature and load conditions. It's important to consult the manufacturer's specifications and guidelines for the specific ice machine model to ensure proper operation.
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.
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.
In a zeotropic blend, the blends boil out at different temperature but at the same pressure. typical example is R704
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).
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.
