R410A refrigerant Superheat Subcooling Calculator

R-22 had been the standard bearer refrigerant for nearly fifty years. However, R-22 harmed the Ozone Layer and a replacement refrigerant needed to be found. This is where our friend R-410A came into play. New machines from 2010 and onwards were banned from using R-22. Instead, they were outfitted with R-410A Add refrigerant to increase subcooling. Reclaim refrigerant to reduce subcooling. Allow +- 2°F tolerance. TECH NOTE: When using the Subcooling method, you can check the suction Superheat to help troubleshoot the TXV. If the expansion valve goes bad, you will have a very low suction Superheat with proper subcooling R-410A Pressure-temperature chart. Author: Jim H. Created Date: 6/19/2012 3:09:17 PM.

Superheat and Subcooling Calculator. Quickly calculate Superheat, and Subcooling measurements for R22 & R410A refrigerants R-410A condensers are factory charged for 15 feet of line set. To calculate the amount of extra refrigerant (in ounces) needed for a line set over 15 feet, multiply the additional length of line set by 0.6 ounces. Note for the formula below, the linear feet of line set is the actual length of liquid line (or suction line, since both shoul I have no experience with 40 ton equipment, but superheat and subcooling values are generally consistent regardless of the type refrigerant. Which would suggest 26 is high for the superheat and 61 is way high for the subcooling. The suction pressure and SST is normal, but 350 could be high for the head depending on the unit SEER Subcooling is when refrigerant continues to lose sensible (measurable) heat after condensing. You can measure this by obtaining the condenser saturation temperature and condenser outlet temperature. Subtract the subcooling value ( which varies from unit to unit) from the saturation temperature and compare it with the condenser outlet temperature •Intersect the 2 numbers on the chart shown on the next slide •If the operating superheat is highadd refrigerant Charging Fixed Restrictor Systems . 50 52 54 56 58 60 62 64 66 68 70 72 74 76 55 9 12 14 17 20 23 26 29 32 35 37 40 42 45 R-410A Superheat (Wet Bulb
