I do appliance repair, In a refrigerator the sealed system that cools it is split into to parts, you have a high pressure side and a low pressure side, I’m trying to determine the difference in volume between them without taking the fridge apart. I logged pressure data with two probes for 24 hours and found that the high and low side equalize at around 12 psi when the system turns off. refrigerant will find a saturation point where some is liquid and some is gas (provided the volume of the refrigerant in gaseous form at that temperature is greater than the volume of the space it’s in). When it equalizes at 12 psi that has a saturation temperature of about 10.5 psi. The majority of low side of the system is in the freezer which maintained a temperature of 0 during these times which would have a saturation pressure of 6.5 psi. The high side would cool to room temperature which was 70 which would have a saturation pressure of 71 psi. I’m great with fixing fridges but not great at math. With a theoretical low of 6.5, a high of 71, and an actual pressure of 12 how much bigger is the low side than the high side in this system? Thank you for the time and consideration
