Subcooling in a refrigeration cycle *Red Italics Indicate Inches of Mercury Below Atmospheric Pressure Saturation Pressure-Temperature Data for R404A (psig)*The outdoor temperature was 80°, and the liquid temperature was 82.4°, but the head pressure and subcooling were astronomically high due to a severe overcharge. The liquid line temperature was limited to just above the outdoor temperature. As more and more refrigerant was added to the system, the head pressure (and, therefore, the condensing ...According to my PT chart, the static pressure of R410A at 65° is 185psi. I'm guessing that's not what you were asking about, but that's what it is. Do you know how to properly charge a system by subcooling (assuming that your metering device is a common thermal expansion valve)? I don't think you should need to recover and weigh in the charge.The subcooling of liquid can be observed with the simple formula. Subcooling value = Temperature of saturated liquid – Temperature of liquid line. The subcooling of liquid can be found when the liquid refrigerant’s temperature falls below the saturation temperature with its existing pressure. There is another similar term, “degree of ... The Saturation Temperature is located on the gauge on this R410A unit by lining up the pressure with the appropriate refrigerant scale. In this example the Sat temp is 43 degrees.
