Superheat on 410a.
For superheat measurement, we are only using a low side gauge (blue gauge). The suction line is the bigger vapor line; locate the suction line service port, and screw the blue line from the gauge on there. Here we will measure the lower saturated temperature (40°F in the example above). Attach the clamp-on thermometer to the suction line.
What is a Good Superheat for 410a? For a refrigeration system using R-410A refrigerant, a good superheat range is typically between 8 to 12 degrees Fahrenheit. This range ensures that the refrigerant is fully evaporated before entering the compressor, optimizing system performance and efficiency.To determine subcooling for R-404A use BUBBLE POINT values (Temperatures above 50°F — Gray Background); to determine superheat for R-404A, use DEW POINT values (Temperatures 50°F and below). ** = exceeds critical temperature Vacuum-Inches of Mercury Bold Italic Figures Pressure-Pounds Per ® Square Inch Gauge FORM IC-11-09 …Jun 8, 2018. 33 Dislike Share Save. 3beltwesty. 8.22K subscribers.
