Volkswagen Polo Service & Repair Manual: Refrigerant R134a Vapor Pressure Table
| The vapor pressure table for every refrigerant is published
in literature for refrigeration system engineers. This table
makes it possible to determine the vapor pressure acting on the
column of liquid in a vessel if the temperature of the vessel is
known. |
| Because each refrigerant has its own characteristic vapor
pressure table, refrigerant can be identified by measuring the
pressure and temperature. |
 Note
| At absolute pressure, 0 bar/psi corresponds to absolute
vacuum. Normal ambient pressure (positive pressure) corresponds
to 1 bar (14.5 psi) absolute pressure. 0 pressure corresponds to
an absolute pressure of 1 bar (14.5 psi) on most pressure gauges
(indicated by -1 bar (-14.5 psi) below 0 bar/psi). |
