Pressure Enthalpy Chart. Scroll down to find download buttons for pressure enthalpy charts in either metric or imperial units. The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition.
This p e chart shows r410a at 100 f saturated condensing temp 10 f sc. The pressure enthalpy chart as shown in fig. Figure 1 is a ph diagram for r 22 refrigerant.
A good service technician can find the usual problem it takes a very good service technician to find the unusual.
The pressure enthalpy diagram in figure 7 shows that the pressure corresponding to liquid hfc 134a at 120 f is about 186 pounds per square inch absolute psia the pressure against which the compressor discharge valves must open is controlled by the vapor pressure of the liquid in the condenser. The blue line on the left of the bubble represents the 100 saturated liquid line. A pressure enthalpy diagram provides this information but can be cryptic to decipher. R1234ze e pressure enthalpy chart.
