R22 subcooling chart.

The pressure-enthalpy chart, as shown in Fig. 2, displays all the pertinent properties for a given refrigerant (in this example R22). The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition. The blue line on the left of the bubble represents the 100% saturated liquid line,The difference between graphs and charts is mainly in the way the data is compiled and the way it is represented. Graphs are usually focused on raw data and showing the trends and ...Actual Line Temp – Sat Temp = Total Superheat. 55°F - 37°F = 18°F. 18°F of Total Superheat > 9°F Target Superheat = Undercharged. Since the actual total superheat measured is higher than the target superheat, we would need to add refrigerant a little at a time until the superheat is the same as the target superheat.Up to 10% lower capacity. Lubricant Recommendation: Compatible with mineral and alkylbenzene oil and if oil return becomes a concern, addition of polyolester lubricant in 5% increments could help resolve the issue. Retrofitting to: R-422B for R-22 Air Conditioning page 95.

Generally speaking, 10-12° of subcooling at the outlet of the condenser coil is most common. However, you must look for the proper design subcooling for the …

Generally, you will see normal superheat (8°-14°) on a system with heat mode TXV, and the subcooling will generally be a bit higher than usual, especially when measured outside. Suction Pressure/EVAP DTD Rule of Thumb Another common old-school rule of thumb is that suction pressure should be close to the outdoor temperature in an R22 system.

Subcooling on systems that use thermostatic expansion valve (TXV) is approximately 10°F to 18°F. To check subcooling on a R-22 system, I will need to attach a thermometer near the liquid line at the condenser. Suppose my temperature reading is 90°F. I would then take the head pressure.In the case of a blend, you Simply read the saturated temperature next to the pressure in the vapor (dew point) column of the chart. When checking the subcool condition the technician will measure the temperature of the liquid line, and the pressure at that point and subtract the measured temperature from the saturated temperature at the end of ...According to the R-22 PT chart, this is equal to about 54°F. With the thermometer, we measured the saturated R-22 temperature of 45°F. Here is how we can calculate the R-22 superheat in this system: Superheat (R-22) = 54°F – 45°F = 9°F. The superheat calculator also gives us 9°F superheat for R-22 refrigerant.Find great deals on eBay for r22 superheat subcooling chart. Shop with confidence. Skip to main content. Shop by category.
