HVAC systems containing a TXV should be charged by ...

Great resource. A little cumbersome to use sometimes, because looking up recommended superheat requires entering system values too. When ambient values change, you have to reenter all the parameters. A little annoying, but still workable. Overall the app is very helpful. Edit: used it again on my R22 system. Airflow is another great feature.

To measure sub-cooling at the condenser outlet or at the TEV inlet to verify that a solid column of liquid is

So, what should the superheat be? First, what is superheat anyway? It is simply the temperature increase on the refrigerant once it has become fully vapor. In other words, it is the temperature of a vapor above its boiling (saturation) temperature at a given pressure. The air around us is all superheated! Head for the hills!To determine the Target Superheat for an air conditioning system with a fixed orifice (such as a piston or capillary tube) measure the indoor WB (wet bulb) temperature with a digital psychrometer and the outdoor DB (dry bulb) temperature with a standard digital temperature reader. Input these temperatures in a superheat chart, calculation, app, or digital manifold set in order to determine the ...SUPERHEAT Procedure: • Use gauges to determine the pressure at the evaporator coil outlet, and a thermometer to get the actual temperature at the same point. • Get the Dew temperature from the “Dew” column • Superheat = Actual Temperature - Dew Temperature Example: Find the superheat on a system which uses Genetron ® R-407C when theTdX 20 PT CHART TEMP.

These charts should not be used for charging. A typical manufacturer’s recommend-ed subcooling is 12°F (7°C). These are only exam-ples of what the manufacturer’s may recommend. Heed all manufacturer’s indications, instructionsIt is my understanding that the correct way to charge an R22 system without a TXV is by getting the actual superheat to match the target superheat. It is also my understanding that the target superheat in Fahrenheit is determined by the equation: Target superheat = (3 x Indoor Wet bulb temperature – 80 – Outdoor ambient temperature)/2. And ...

Calculating superheat: Measure the low-side pressure with your gauge. Convert pressure to temperature with an app, slide or chart. Next, take the temperature of the suction line where it leaves the condensing unit, though stay 4-6 inches from the compressor.
