| Vapor pressure table for R134a refrigerant gas |
| Technical literature on refrigeration systems contains a table showing vapor pressures for each refrigerant gas. This table makes it possible to determine the vapor pressure applied on the liquid column in the tank, if the temperature inside the tank is known. |
| As there is a specific vapor pressure table for each type of refrigerant gas, it is possible to determine which refrigerant gas is being used based on measurements of pressure and temperature. |
Note | When pressure is expressed as absolute pressure, 0 (zero) bar corresponds to absolute vacuum. Normal atmospheric pressure (overpressure) is equal to 1 (one) bar of absolute pressure. On most pressure gauge scales, 0 (zero) bar equals 1 (one) bar of absolute pressure (identifiable by the indication (–1) below the (0)). |
