or standing/still state/equalized refrigerant loop pressure of a stopped system.
If the entire system is at uniform temperature, it will be whatever the unit is at, so if you leave a window A/C in your trunk and its at 120F, the entire hermetic system will pressurize to 264 psi or so for HCFC-22
In the case of a split system where the condensing unit's sun baked to 120F and evaporator coil is at 90F, what can I expect the static pressure to be?
Lowest temperature point, highest point, or something in between?
For a package RTU in Phoenix, AZ on a 105F baked in the sun, is it unreasonable to assume it will reach 135F? (vapor pressure of R-22 is 315 psi).
This means you can leak test any component using nitrogen at whatever R-22 vapor pressure system is expected to see under normal design parameters, no? So for a RTU package, even if you don't know the maximum permissible pressure, its ok to pressurize the system to at least 315 psi, no?
