R-32 along with R-125 gets you that R-410A that is found in nearly every air conditioner today. However, in recent years there has been a push to slowly phase down R-410A. That is because of 410A’s very high Global Warming Potential, or GWP.

subcooling somewhere around 12-15 degrees F. Suction Pressure around 21-22 psia = -15 to -14 deg.f. Suction line temp. leaving evap. = -12 to -2 deg. F. (The temperature swing is -12 to -2) It stays quite stable. Isn't radical with the temp. swing. box temp. -5. It's an empty walk in box about 7 x 10 foot square.HVAC Buddy®. If you are servicing equipment the best way to begin diagnosis and determine the proper refrigerant charge is to use HVAC Buddy®, a set of gauges, and a thermometer. Over 100 refrigerants including newer azeotropic blends. Calculates Superheat, Subcooling, and Airflow targets. Superheat for fixed capillary or Subcooling …Note: Do not adjust charge based on superheat on systems with thermal expansion valves (TXV’s). TXV’s control the superheat. You can, however, check the superheat to see if the TXV is working properly. To Determine Sub-Cooling: 1. Take the high side pressure and convert it to temperature using chart or gauge. 2.Overall Process: Enter refrigerant, temps, and pressures. The math is done for you; superheat calculations, subcooling calculations, and airflow calculations all display Target, Actual, and Difference. Repeat steps 1-2 until all HVAC Diagnostics check out as "Okay"; send system status report VIA text message or email as needed.

TEMPERATURE PRESSURE CHART - at sea level To determine subcooling for R-404A use BUBBLE POINT values (Temperatures above 50°F — Gray Background); to determine superheat for R-404A, use DEW POINT values (Temperatures 50°F and below). ** = exceeds critical temperature Vacuum-Inches of Mercury Bold Italic Figures Pressure-Pounds Per ® Square ... AllThingsHVAC Last updated: February 7, 2018 This brief guide explains how to measure superheat and subcooling. As a review, superheat is heat added to the refrigerant above its boiling …As an example, Trane includes a pressure curve chart with many heat pump condensing units. Be sure to use the scale all the way to the right that says heat mode. ... You can still check the subcool and superheat in heat mode; the problem is that since there are rarely any set guidelines, it is difficult to tell when the charge is set correctly ... ….

October 4, 2023 by GEGCalculators. Superheat in HVAC refers to the temperature of refrigerant vapor above its saturation point in the evaporator. Ideal superheat is typically 10-15°F. Subcooling involves refrigerant liquid temperature below its saturation point at the condenser outlet. Normal subcooling is often 10-15°F.Step 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

Note: The amount of vapor superheat is always calculated from the actual saturated vapor temperature; the amount of liquid subcool is always calculated from the actual saturated liquid temperature. Example: Freon™ MP39 operating at an evaporator pressure of 12 psig and a condenser pressure of 163 psig (same conditions as shown in Figure 1).SuperheatCalc —SuperheatCalc is a free app in the Apple App Store and Google Play, enables HVAC service technicians to calculate target superheat for systems using fixed-orifice expansion devices, superheat and subcooling for 26 refrigerants, and airflow and psychrometric calculations to aid with field service of HVAC&R equipment. The app was ...
