R410a subcooling chart
• R-410A systems operate at approximately 60% higher pressures (1 6 times) than R-22 systems Do not use R-22 service equipment or components on R-410A equipment Use appropriate care when using this refrigerant Failure to exercise care may result in equipment damage or personal injuryApr 8, 2020 7 min read The HVAC Subcooling Charging Method, Explained! Updated: Oct 31, 2022 In this article, we will define subcooling, calculate subcooling, explain how to use subcooling to check the refrigerant charge, and show where the measurement points are taken on an air conditioning system. Subcooling Formula:

Residential Sector. BPA helps its customers meet their energy-efficiency needs through targeted offerings to multiple sectors. The Residential sector delivers program infrastructure and measures to increase energy-efficiency improvements in the Northwest, and help reduce electricity consumption.Units manufactured after 7/09 used this subcooling chart. Check out the 036 unit at 12 SC. Then Lennox updated the chart with this update on 5/13. Somehow a 036 unit goes from 12 SC to 4 SC without any changes to the product. So I am charging a 13ACX-036 per the new label at 4 SC.Each Goodman air conditioner comes with a data plate that provides information about the correct amount of refrigerant needed for the system. However, a generalized charging process might look something like this: Check the outdoor temperature. This will be used to find the target superheat or subcooling.
Superheat and subcooling calculations can be calculated the same way we have always done with R-22 refrigerant. The only difference will be the higher pressure-temperature relationship when reading the temperature-pressure chart. The temperature glide for R-410A is only 0.3 degrees F and can be ignored, and fractionation is not a concern.Calculate superheat R410a Superheat charts (Cooling, NON-TXV) Instructions Measure wet bulb temperature with a sling psychrometer or a temperature and humidity thermistor. Use a digital thermometer for all temperature measurements. Do NOT use mercury or dial type thermometers.Given cold ambient, the SCT can come down close to ambient (9C). Subcooling can be very low in cold ambients, regardless of charge. Low subcooling is not a valid symptom. I block off the condenser, check for high subcooling, which actually means something... and then I check the superheat. In the second scenario, the …R134A Pressure-Temperature Chart-49-45: 1-17.2 51: 10.6 101: 38.3-48-44.4 2-16.7 52; 11.1 102; 38.9-47-43.9 3-16.1 53; 11.7 103; 39.4-46-43.3 4-15.6 54; 12.2 104; 40-45-42.8 5-15 55; 12.8 105; 40.6-44-42.2 6-14.4 56; 13.3 106; 41.1-43-41.7 7-13.9 57; 13.9 107; 41.7-42-41.1 8-13.3 58; 14.4 108; 42.2-41-40.6 9-12.8 59; 15 109; 42.8-40-40 10-12.2 ...

This is a very useful tool that takes the guess work out of charging cooling systems. One side of this tool is a slide chart used for calculating superheat for a NON-TXV system and the other side is a slide chart used to calculate subcooling on a TXV system. The photo shows both sides of the tool. ….

chart for R410a, this pressure corresponds to a saturation temperature of 110F°. The actual measured temperature of the liquid leaving the condenser is 98F°. When we subtract 98F° from 110F° we get a value of 12 degrees. The liquid R410a leaving the condenser has a subcooling value of 12F°. Condenser pressure = 365 psig = 110F° from P-T ChartStep 3 – subtract required subcooling (Step 1) from converted temperature (Step2) – This is the required liquid line temperature. Step 4 – Measure liquid line temperature. If the measured liquid line temperature does not equal the required liquid line temperature: Superheat Charging Chart - Cooling - non-TXV - R410A & R22

During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on ...
