R410a superheat chart
Most R-410A cylinders have an internal dip tube which allows the feeding of liquid when the cylinder is in an upright position. They must be inverted for for vapor flow. …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. If you would like to read more about R-410A refrigerant please have a look at our Puron fact sheet. R-410A PT Chart.

But why do we care? We measure superheat (generally) on the suction line exiting the evaporator coil, and it helps us understand a few things. #1 – It helps ensure we are not flooding the compressor. •The SUPERHEAT from inside the evaporator to the inlet of the compressor is the suction line temperature at the compressor minus the saturated evaporator temperature (from PT chart). •Amount is determined by indoor wet-bulb and indoor & outdoor dry-bulb temperatures. •Can be as low as 5⁰F & as high as 40⁰F depending on … i8 pill white The clamp-on thermometer shows that the saturated refrigerant temperature is 56°F. Here’s how to calculate superheat for this system: Superheat (R-410A) = 56°F – 45°F = 11°F primus touristpickens county humane society adoptionparallon perks Using a two-column PT chart When checking a superheat or subcool temperature the procedure is the same as for a single-component refrigerant. Superheat is checked by measuring the temperature of the vapor line, measuring the pressure, then subtracting the saturated temperature from the measured temperature.
