Low pressure refrigerants include substances like ammonia (R-717), carbon dioxide (R-744), and some hydrocarbon refrigerants such as propane (R-290) and isobutane (R-600a). These refrigerants are often used in various applications, including industrial refrigeration and some commercial cooling systems. Their low pressure characteristics can make them suitable for specific temperature ranges and environmental conditions.
Reusable containers under high pressure, such as gas cylinders, typically need to be tested and date stamped every 3 to 5 years, depending on regulatory requirements and specific usage conditions. This testing ensures the integrity and safety of the containers. Additionally, any signs of damage or if the container is subjected to extreme conditions may necessitate more frequent inspections. Always refer to local regulations and manufacturer guidelines for specific requirements.

Mixing refrigerants can lead to changes in the pressure and temperature of the system, which could potentially create a hazardous situation. While it may not directly cause an explosion, it can result in equipment malfunction, leaks, or other safety risks. It is crucial to follow manufacturer guidelines and industry standards when handling refrigerants to prevent accidents.
The suction pressure required to maintain a 40 degree evaporator coil temperature depends on the refrigerant being used, as different refrigerants have different pressure-temperature characteristics. A typical range for R-22 refrigerant would be around 55-60 psig. It is important to consult the specific pressure-temperature chart for the refrigerant being used.
It depends on the ambient condensing temperature. A pressure temperature comparison chart for 134Aa can be found at http://www.csgnetwork.com/r134apresstempconv.html Different refrigerants condensence and evaporate at different temps/pressure
The pressure and the specific refrigerant properties determine the temperature at which a refrigerant vaporizes. As pressure increases, the boiling point of the refrigerant also increases. Different refrigerants have different boiling points at different pressures.

Their low pressure characteristics can make them suitable for specific temperature ranges and environmental conditions.
High-pressure refrigerants typically include substances such as R-410A and R-134A. These refrigerants operate at higher pressures compared to low-pressure refrigerants like R-22. The designation of "high pressure" can vary depending on the specific application and system design, but generally, refrigerants that function above 50 psi at standard operating conditions are classified as high-pressure refrigerants.

Because gasses expand when the temperature rises, which puts extra pressure on the containers which again may cause them to explode if the temperature rises too much. When stored cold, the level of pressure will stay well within the limits that the containers safely can withstand.
You need to specify what kind of system. Automotive AC systems and home AC systems use different refrigerants. That, along with the temperature/pressure relationship and ambient air temperature, all factor into what your high pressure (and, consequentially, low pressure) side should read on your manifold pressure gauge.

The difference would be due to the different refrigerants used by each which is not given. Also the refrigerator will have a more constant condenser pressure because it is within an environment where the ambient temperature varies little.END

Mixing 12A with R134A is not recommended because they are different refrigerants with distinct chemical properties and pressure characteristics. Combining them can lead to system inefficiency, increased pressure, and potential damage to the refrigeration system. Additionally, it can complicate future servicing and recycling of refrigerants. It's best to use refrigerants as specified by the manufacturer.
