Hi everyone happy new year to you guys! I got questions! Does refrigerant temperature ( saturation temperature) equal or pretty close to embient temperature?if yes and why? If close to embient temperatures but only during system standing pressure not operating right? Use Pt chart to measure in close system for refrigerant pressure n temperature in seal system!

In a sealed system, the interior pressure will be the vapour pressure of the refrigerant at the temperature of the system, if there is enough liquid refrigerant present. You can use the P/T diagram for the specific refrigerant to determine that pressure.
If there is no liquid refrigerant present, the pressure will be determined by the total mass of refrigerant present and its molecular weight, the volume of the system, and the temperature. Most refrigerants have behavior sufficiently close to ideal that the ideal gas law can be used at least as a first approximation.
Note that you must use absolute temperatures and pressures.Br. Jamie, osb
