What should the high and low side pressures be for r22?
Keeping this in consideration, what should my Pressures be for r22?
|Example R-22 Refrigerant Temperature vs Pressure Data|
|Ambient Temperature in °F1||R22 Vapor Pressure at Sea Level||R-22 Low Side Pressure2|
|95°F (35°C)||181.9 psig||68 psi|
|110°F (43.3°C)||226.4 psig|
|150°F (65.6°C)||381.7 psig|
Additionally, what is the suction and discharge pressure for r22? For example, a high-efficiency condensing unit using R-22 typically operates with a suction pressure of about 68 psi and a discharge pressure of about 250 psi at an outdoor temperature of 95°F.
Herein, what should the high and low side pressures be?
The low-side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. On a properly working system, high-side pressure will be about twice the ambient temperature, plus 50 PSI.
