When the motor remains off for a certain period, pressure in the whole system equalizes the refrigerant low-pressure number so that it can stay close to the outdoor or the room temperature. It is observed that R22 pressure at 85 degrees settles at 143.7 psi, while for the other system, like R410, the pressure at 85 degrees is 235.9 psi.
