Total Superheat = Actual Vapor Line Temp - Sat Temp. Total Superheat = 29°F so there is a problem such as one of the following:Charging a A/C system by subcooling. Determine your target subcooling. This is usually displayed on the back of the nameplate, located on your condensing unit. If not, 10-15 degrees F will get you ballpark range. With the unit running, connect your high side refrigerant gauge, to the liquid line port, or fitting.145 °F. 571.7 psig. 150 °F. 607.6 psig. 155 °F. 645.2 psig. You can see that this R410A pressure chart includes high and low side pressures at temperatures ranging from -60 °F to 155 °F. Higher temperature equates to higher pressure. Here are 4 examples of how you can use this chart: What is a good superheat and subcooling on 410a? The superheat of your heating and cooling system should be 10F at the evaporator. If a thermostatic expansion valve is present (TXV), the subcooling target range should be between 10F and 18F. Your compressor's temperature should sit between 20-25 degrees Fahrenheit. Connect to virtual expertThe pressure needle intersects at 100°F saturated temperature for R-410A. Therefore, the saturated temperature inside the condenser coil is 100°F. Below is the example: Calculate the subcooling based on the picture: Sat Temp - Actual Line Temp= Subcooling. 100°F - 95°F = 5°F of Subcooling.The dire ramifications of under- and overcharging an air conditioner or heat pump were covered last month ("Using the Superheat Method to Charge A/C Systems,"The News, Aug. 13, page 1). The first installment also contained a basic explanation of what superheat is and what it tells you about the condition of the evaporator coil.An R410a and R22 charging calculator or the "Non TXV Charging Guide" are required to determine the target total superheat. Because these systems do not "control superheat" it is critical that the airflow be as close to possible to correct prior to charging as the system will be charged to the airflow.Fix your HVAC orifice with a fixed orifice metering device.

General Guide Outdoor High side Low side Temp gauge temp gauge temp 80 100-135 32-35 Jun 3, 2004 · Superheat is a measured value. It is the difference between two temperatures. Superheat is measured as the difference between the actual temperature of the refrigerant vapor and the saturation temperature of the refrigerant at that same point. Superheat on the system's low side can be divided into two types: evaporator superheat and total (or ... Subtract the two numbers to get superheat. For example, 68 psi suction pressure on a R-22 system converts to 40°F. Let's say the suction line temperature is 50°F. Subtracting the two numbers gives us 10°F of superheat. Superheat for most systems should be approximately 10F measured at the evaporator; 20°F to 25°F near the compressor. This is How to Check the Refrigerant Charge on a System Without a TXV that has a Piston/Orifice or Capillary Metering Device in front of the Evaporator Coil....The model ASX14 superheat and subcooling accessory head measures refrigerant pressure and temperature simultaneously. It then calculates and displays superheat or subcooling. It has a 1/4” industry standard fitting for actual pressure. A pipe clamp thermocouple is included for temperature. Select R22 or R410A. Select superheat or subcool-The unit had 20° subcool, but also 30+° superheat. It's 410a with a txv and the nameplate says 10° subcool. So subcool and superheat are both too high, which isn't something you see very often. I could only really come up with one answer. A TXV stuck partially closed, and an overcharge from when he stupidly attempted to charge based solely ...Since superheat is defined as any sensible heat gained after the saturated vapor point in the evaporator, the evaporator superheat would be 11°F (56°F – 45°F), where 56°F is the evaporator outlet temperature and 45°F is the saturated vapor (dew point) temperature corresponding to 70 psig evaporator pressure.What is the best 410a superheat? The superheat measured at the condensing unit can vary because suction line lengths vary. The superheat should be between 10 and 15 degrees with short line lengths (less than 30 feet). Superheats of 15 to 20 degrees are normal with longer suction line lengths (between 30 and 50 feet).5) Low-side GAUGE temperature + superheat = actual line temperature. 6) If more than 5 degrees over, add charge to decrease line temperature. 7) If more than 5 degrees under, remove charge to increase line temperature.
