What is the target superheat for R-410A in this situatio

To calculate the superheat, subtract the saturation temperature from the measured refrigerant temperature: Superheat = 45°C – 10°C = 35°C. In this example, the superheat value is 35°C, indicating that the refrigerant is 35 degrees above its saturation temperature at the given pressure.There seems to be some confusion here. I calculated the target superheat to be 24F using this online calculator.That means theoretically, it should be 24F.. The actual measured superheat was initially very low, just a few degrees F so I recovered some refrigerant from the system and it's now currently around 10 degrees, so theoretically I need to recover more refrigerant out of the system.A tax table chart is a tool that helps you determine how much income tax you owe. To correctly read a federal income tax table chart, here are a few things you need to do so that you have the necessary numbers to effectively use the chart.Target superheat is the recommended superheat for the given indoor and outdoor environmental conditions. Environmental conditions affect the amount of actual superheat found in a system.
