R410a subcooling chart
Subcooling is a measurement of temperature DECREASE of a liquid below its saturation (mixed liquid/vapor) temperature at a given pressure. For example, water boils at 212° Fahrenheit at sea level (atmospheric pressure of 14.7 PSIA). If water is 212°F and at atmospheric pressure at sea level, you can be sure it is at saturation, which means it ...jsherrill77 · #7 · Dec 23, 2008. Okay, since this is a TXV system you must check charge by subcooling method and not superheat. It's really not to difficult to do. First you hook up your gauges. let system run for 15 minutes. If your gauges also show different refrigerants you won't even need a pressure/temp chart.

Apr 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:Because Freon™ 407C and Freon™ 410A are mixtures of HFCs, they have zero ODP. Table 1 lists the chemical names and formulae of the components that make up Freon™ 407C and Freon™ 410A. Table 1.

Run system at least 10 minutes to allow pressure to stabilize. • 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 injury(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 ambient conditions. System Super HeatSuperheat 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 …Physical Properties Of R22. In parallel to using the R22 PT chart, professionals will usually need to know some of the following R22 physical properties: R22 liquid density at -69°C: 1.49 g/cm 3.

To check subcooling, attach a thermometer to the liquid line near the condenser. Take the head pressure and convert it to temperature on a temperature/pressure chart. Subtract the two numbers to get the subcooling. For example, 275 psi head pressure on an R-22 system converts to 124°F. The liquid line temperature is 88°F.
