What is the target superheat for R-410A in this situation? Let’s use the target superheat formula and calculate this manually: Target Superheat (R-410A) = (3 × 69°F – 80°F – 105°F) / 2 = 11.0°F. We see that the target superheat for R-410A refrigerant in this system is 11°F.Make sure there is as much liquid in the evaporator as possible, but ensure it is completely boiled off before it enters the compressor. This can be seen by measuring the superheat. To measure evaporator superheat: Record the actual temperature at the TXV bulb with a probe. Record the evaporating pressure at the TXV bulb. (Low side gauge …We will use the manifold gauge (low side suction line; blue gauge) to measure the saturated state temperature (40°F in the example), and we will use a clamp-on thermometer to measure the superheated vapor temperature (48°F in the example). For superheat measurement, we use the blue low side gauge.Take a sensible temperature measurement of the line and pressure reading. Find the pressure on your P-T card, gauge, or app and look for the corresponding saturated temperature. Find the difference between the measured sensible and saturated temperatures. The temperature increase from saturated to sensible is the superheat. This video will show you how and where to measure the temperature on a R-410A Split System for calculating superheat and sub cooling measurements. You can ap...
