The boiling point of R-12 is given as -29.8oC.
Now replaced by R-134A which had a boiling point of -26.3oC.
Some oils and rubbers previously used with R-12 may not be compatible with R-134A.
The condensing temperature of argon is -185.86 degrees Celsius at atmospheric pressure.
The discharge line is hotter than the condensing refrigerant because it is where the high-pressure, high-temperature refrigerant vapor exits the compressor after being compressed. The condensing refrigerant, on the other hand, is in the process of releasing heat to the surrounding environment in the condenser, leading to a lower temperature.
The condensing temperature for an R22 system with a head pressure of 296 psig would typically be around 120-130°F. This is based on the saturation temperature corresponding to a pressure of 296 psig on the R22 pressure-temperature chart.
The condensing temperature of the refrigerant in a standard efficiency unit should be around 30-40 degrees Fahrenheit higher than the outdoor ambient temperature. Therefore, when the outside temperature is 90 degrees, the condensing temperature of the refrigerant would be around 120-130 degrees Fahrenheit.
"Condensing" typically refers to the process of changing a substance from its gaseous state to its liquid state by removing heat. This transition usually occurs when the substance reaches a certain temperature known as its "condensation point."

The condensing temperature of argon is -185.86 degrees Celsius at atmospheric pressure.
The standard condensing temperature of refrigerant 134a is around 130°F (54.4°C), and the standard evaporating temperature is around -15°F (-26.1°C).

The condensing point is the temperature at which a substance changes from a gas to a liquid during the process of condensation. It is the point at which vapor molecules lose enough heat energy to form a liquid.
The discharge line is hotter than the condensing refrigerant because it is where the high-pressure, high-temperature refrigerant vapor exits the compressor after being compressed. The condensing refrigerant, on the other hand, is in the process of releasing heat to the surrounding environment in the condenser, leading to a lower temperature.
The condensing temperature for an R-12 system with a head pressure of 175 psig would be approximately 119°F. This is based on typical saturation temperature-pressure relationship for R-12 refrigerant.
The condensing temperature for an R22 system with a head pressure of 296 psig would typically be around 120-130°F. This is based on the saturation temperature corresponding to a pressure of 296 psig on the R22 pressure-temperature chart.
As rule of the thumb, refrigerant condensing temperature should between 1-2 degreeC higher than the exiting water temperature, this temperature difference is technically called condensing temperature approach. I f the approach is below or above means, system is flooded with refrigerant or system got starve. Above method is also effective in determining if the condenser shell needs maintenance for sclale, sludge build up removal. I am refrigeration mechanic.
The condensing temperature of the refrigerant in a standard efficiency unit should be around 30-40 degrees Fahrenheit higher than the outdoor ambient temperature. Therefore, when the outside temperature is 90 degrees, the condensing temperature of the refrigerant would be around 120-130 degrees Fahrenheit.
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.
R12 (dichlorodifluoromethane) can decompose into phosgene and HF (hydrogen fluoride). R22 (chlorodifluoromethane) can decompose into phosgene and HF as well. Both reactions can occur under high temperature or in the presence of a catalyst.
