Vapor enthalpy and entropy are calculated from the standard Martin-Hou ... Critical Density …The pressure gauges for this refrigerant stays between 22 PSI and 57 PSI (pounds per square inch). But you have to keep in mind that there are two different sides to this chart. And you have to consider the low as well as the high side. Hence, the normal low-pressure side for R 134a needs to be less than 90 degrees.

Let's get started and see what we can do.Most manufacturers recommend charging by super heat and subcoolimg rather than pressures alone,and will vary slightly by manufacturer but as a rule low side of about 110 and high side about 280at 70 degree ambient. This will of course increase as temp warms up.ON an 85 degree day,probably 130 to 135 and ...

So if it's 85º out the saturation pressure in the system (that's been sitting off) should be 255 psi for 410a. If it's much different than that, then you would want to treat it as contaminated refrigerant when recovering. I assume 5 below would mean 80º in this example to account for the indoor coil being colder, so 236 psi.
