What is the pressure of R22 at 41° Fahrenheit?

To determine the pressure of R22 refrigerant at a specific temperature, you can refer to pressure-temperature charts that detail the relationship between the temperature of the refrigerant and its corresponding pressure.

At 41° Fahrenheit, the saturated pressure of R22 is indeed approximately 70 PSIG. This is derived from the thermodynamic properties of R22, which is important to understand in refrigeration and air conditioning applications. Such charts are essential for HVAC technicians to ensure that systems operate within the designed parameters.

The other options would represent pressures at different temperatures, which do not correspond to the saturated pressure of R22 at 41° Fahrenheit. Understanding these properties helps technicians effectively diagnose and repair HVAC systems, ensuring efficient operation and compliance with safety standards.
