R410a subcooling chart
The Superheat Calculator is a tool used to calculate the superheat of a refrigerant in an air conditioning or refrigeration system. Superheat is defined as the temperature of a vapor above its boiling point or saturation temperature. The calculator determines the amount of superheat in the system by subtracting the saturation temperature from ...You can also use the R-410A PT chart to adequately calculate the superheat, total superheat, and subcooling temperatures. Below you will find two charts: 410A chart for degrees Fahrenheit (°F) and 410A chart for degrees Celsius (°C).

Refrigerant Reference. This is a very useful tool that takes the guess work out of charging cooling systems. One side of this tool is a slide chart used for calculating superheat for a NON-TXV system and the other side is a slide chart used to calculate subcooling on a TXV system. The photo shows both sides of the tool.These charts are an example of a generic superheat charts for a typical fixed orifice, split res-idential system. 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.
