Normal operating pressures for R12 refrigerant typically range from about 30-40 psi on the low side and 200-250 psi on the high side, depending on the ambient temperature and system design. These pressures can vary slightly based on specific equipment and conditions. It is important to refer to the manufacturer's specifications for precise values tailored to a particular system. Always handle refrigerants with care and ensure proper safety protocols are followed.
No. R12 systems are designed for R12. The lubricating oil for 134a is synthetic and will attack the o-rings in a R12 system. I think the operating pressures are also different.Samething is now happening to residential ACs. R22 is out and 410 is in.They are not compatible.SOL
The pressures depend on the temperatures so it is not possible to give "normal" temperatures. The pressures change with the outdoor and indoor temperatures. You need to be EPA certified to attach gauges to the unit to check the pressures.

You have to have a permit to buy R12 and it is very expensive. Any system that uses R12 can use 134 the replacement for R12. You will need adapters that screw onto the old fittings that accept the hose that hooks to the 134 can. You add freon to the low side of the system. The adapter are different sizes so you cannot put it in the high pressure side. Yes, if you have any mechanical knowledge at all, you should be able to charge the system without much trouble. OR you can buy all the R12 you like for cheap from Mexican sources and keep the longevity of your original equipment and lower operating pressures of R12. They way your system was designed. R12 comes in everyday by the truckload thanks to our new open border laws.
The normal operating pressure of R-404A varies depending on the specific application and operating conditions, but it typically ranges from about 20 to 40 psi for the low side and 150 to 250 psi for the high side at standard ambient temperatures. In commercial refrigeration systems, for instance, the pressures can be higher due to the lower evaporating temperatures. It's important to refer to specific system guidelines and manufacturer recommendations for accurate operating pressures.
The normal operating pressures for the air conditioning system on a Mercedes ML320 typically range from 30 to 40 psi on the low side and 200 to 250 psi on the high side when the system is running at idle. These pressures can vary slightly based on ambient temperature and specific conditions. It's important to check the manufacturer's specifications for the exact values and ensure the system is properly charged for optimal performance.
Operating at even higher pressures can increase the risk of equipment failure, increase operating costs, and require additional safety measures. Additionally, operating at very high pressures may not significantly improve the process efficiency beyond a certain point, making it unnecessary to operate at even higher pressures.
No it's not. R22 is designed for use in home HVAC systems where as R12 is intended for automotive systems. Using R22 in an automobile will cause swelling of seals and hoses, possible compressor failure due to different running pressures.

the normal operating temperature for cars is around 190 degrees.
