The pressure of R404A for recharging a refrigerator can vary depending on the specific refrigerator model and the manufacturer's recommendations. However, typical recommended operating pressures for R404A refrigerant in a refrigerator range from about 160 psi to 250 psi on the low side and from 250 psi to 350 psi on the high side. It's crucial to consult the refrigerator's instruction manual or a qualified technician to ensure the correct pressure levels are maintained during recharging.
Charging an R404A unit involves connecting a charging hose from a refrigerant cylinder to the low-pressure side of the system. The refrigerant is then added slowly, while monitoring the system's pressure and temperature to ensure proper charging levels are reached. It is recommended to consult a professional technician to ensure correct charging procedures are followed.
To charge a walk-in cooler with R404a refrigerant, you will need to connect a refrigerant cylinder to the system using a manifold gauge set. Open the cylinder valve and slowly add the necessary amount of refrigerant into the system according to the manufacturer's specifications. Be sure to monitor the system pressures and temperatures as you charge it to ensure that it is properly charged.

No r404a is not compatible with r409a, r134a and 404a use the same lubricates and are compatible but r409a use a different lub making them incompatible
No. There'll still be residual traces of R22, even if the cylinder is empty, and it won't blend with the R404A. Furthermore, the R22 cylinder will be labeled as such, and it's actually a crime to have such cylinders improperly labeled.

Someone please correct me if I am wrong, but ZP is in relation to the thermal expansion valve. This valve limits pressure and flow through the evaporator. Sporlan uses SZ and SZP to designate the thermostatic charge and is related to refrigerant r404a. Can anyone explain what the S is in relation to?
Depends who you purchase it from and in what quantity.
R410A is a high-pressure refrigerant that operates at higher pressures than R22 and R404A. As a result, it requires more robust and specialized equipment to handle it safely. Its higher pressure also means that leaks can pose a greater risk, requiring stricter safety precautions to minimize potential hazards.
If a compressor designed for R404a runs with nitrogen instead of refrigerant, it will not be able to effectively compress the nitrogen gas. This could lead to overheating of the compressor motor and potential damage due to lack of proper cooling and lubrication. It is essential to use the correct refrigerant to ensure the compressor operates efficiently and effectively.
The condensing temperature for R404A refrigerant typically ranges from 100°F to 130°F, depending on the operating conditions of the refrigeration system. It is important to consult manufacturer's guidelines and pressure-temperature charts for accurate information.
