Refrigerant R-502 is a medium-pressure refrigerant primarily used in commercial refrigeration systems, particularly in low-temperature applications such as freezers and cold storage facilities. It was commonly utilized in older refrigeration and air conditioning systems, especially in transport refrigeration and industrial processes. However, due to its ozone depletion potential, R-502 has been phased out in many regions in favor of more environmentally friendly alternatives.
R502 is a refrigerant blend that contains R22 and R115, and it is considered a substitute for R12 in certain applications. While R502 can be used in systems designed for R12, compatibility depends on the specific system components and conditions. It's essential to check the manufacturer's guidelines and consider factors like oil compatibility and system pressure before making a switch. However, due to environmental regulations, R502 is also being phased out, similar to R12.
If a technician discovers that R502 was added to an R22 system, he should first isolate the system to prevent further contamination. Next, he should recover the mixed refrigerant using a certified recovery machine and dispose of it according to environmental regulations. After that, the technician should thoroughly evacuate and vacuum the system before recharging it with the appropriate R22 refrigerant. Finally, he should conduct a pressure and leak test to ensure the system is functioning correctly and safely.
Disposable refrigerant containers are only used for virgin refrigerant.
Refrigerant are used in refrigerator for cooling and dehumidifying indoor air.
Not unless you like the idea of destroying your AC system.
The refrigerant typically used in refrigerators is called R-134a.
134a refrigerant
The oil used to lubricate the compressor is cycled with the refrigerant.
The most common refrigerant used in refrigerators is R-134a.
The refrigerant commonly used in new refrigerators is R600a, also known as isobutane.
The most common refrigerant used in household refrigerators is R-134a.
The amount of refrigerant typically used in a refrigerator is around 4 to 6 ounces.
