How do you read a pH graph?
On the P-H diagram, pressure is indicated on the y-axis and enthalpy is indicated on the x-axis. Typically enthalpy is in units of Btu/lb and pressure is in units of pounds per square inch (psi). The upside down U figure shown on the diagram designates the points at which the refrigerant changes phase.
What is the working pressure of R-410A?
For R-410A, a working pressure capability of at least 400 psi is recommended (this includes recovery cylinders). Standard DOT recovery cylinders rated for 350 psi should not be used. Use only DOT recovery cylinders rated for 400 psi or higher when recovering R-410A.
What is R410A PT charts?
Pounds Per Square Inch (psig) is most commonly used to express pressure levels at a specific temperature for R410A refrigerant. In universal units, 1 psi equals to about 6895 N/m 2. Usually you can get these R410A PT charts with every R410A refrigerant. For some people, using a graph instead of a chart is easier.
What is the R410A pressure at 72°F?
We can see that at 72°F, the R410A pressure is 208,4 psig. Example 2: What are 410A pressures on an 85 degree day? The operating pressure of 410A on an 85 degree day is 254.6 psig. Example 3: What are 410A pressures on a 70 degree day? The operating pressure of 410A on a 70 degree day is 201.5 psig.
What does PSI stand for in R410A?
Pounds Per Square Inch (psig) is most commonly used to express pressure levels at a specific temperature for R410A refrigerant. In universal units, 1 psi equals to about 6895 N/m 2.
What is R410A refrigerant?
R410A is one of the most commonly used refrigerants. It’s patented by Honeywell, and known under several other names such as “AZ-20”, “Genetron R410A”, “Puron”, and so on. It’s the preferred freon for residential air conditioners, replacing the older R22 according to the Montreal Protocol and subsequently phasing out of R22.
