Be aware that various brands and conditons will cause variations. Below the calculator is an approximate chart relationship of temperature to pressure.
Now that I have indicated that, it relieves a lot of pressure. Psia is absolute pressure, which means it is gauge pressure + 14.7 psi. Psig (inches of mercury) is equal to psia – 14.7 at sea level. Psig is equal to psis at sea level (14.7 psi). Temperature- Constant temperature lines generally run in a verti-cal direction in the superheated vapor & sub-cooled liquid. Enthalpy- The horizontal axis of the chart shows the heat con-tent of the refrigerant in Btu/lb.
To obtain gauge pressure, subtract atmospheric pressure. The term gauge signifies that the pressure has been read from a gauge that actually measures the difference between the pressure of the fluid or gas and the pressure of the atmosphere. Pressure- The vertical axis of the chart, in psia (see pink line). Enter the temperature in either F or C degrees and the returned result is the alternate temperature and determined pressure in Barg and psig. It is the common phase "environment friendly" replacement for R12 but does require system retrofit modifications. It is used in both automotive and commercial air conditioning applications. Saturated Liquid, Evaporation, Saturated Gas, Saturated Liquid, Evaporation. This refrigerant takes a significant step forward in environmental protection by achieving an ozone depletion factor of zero. Pressure, Temperature, Specific Enthalpy, Specific Entropy, Specific Volume. Refrigerant R134a or HFC-134a is a commercially available hydrofluorocarbon (HFC) refrigerant for use as a long-term replacement for R-12 in new equipment and for retrofitting medium temperature CFC-12 systems.

Refrigerant R134a or HFC-134a was developed to meet these needs. Recent Saturation Properties (max 20) - download - clear Pressure. Environmentally acceptable replacement compounds are therefore needed for use in existing medium and low temperature refrigeration applications. Production of chlorofluorocarbons (CFCs) has been phased out. This script determines the gas pressure based on temperature of R134a refrigerant. This calculator requires the use of Javascript enabled and capable browsers. cites inflation, pressure on drug prices in 450-person layoff endpts.

This affects the chart, input values and calculated values. Knovels steam calculators provide a full implementation of the 2012 cumulative. Units-system can be set to Metric(SI) or Imperial(I-P).Chart Style: Mollier/ Psychrometric-Chart.The new condition of the air is calculated and this new point and the process will be automatically drawn in the diagram. With this online tool you can simulate and visualize thermodynamic processes that affect moist air.Īfter entering the Air start conditions, you can enter various actions, like " Mix", " Heat", " Cool", " Heat Recovery" and " Humidify". Psychrometric Chart calculator and Sketcher At the Thermodynamics Conference in Los Angeles (1923), it was decided to name the diagram after Richard Mollier in his honor. In our interactive log ph diagram, refrigeration cycles can be parameterized in different ways.
The Psychrometric Chart is also known as the "Mollier-Diagram". The chart is is combined with the Relative Humidity lines and the Enthalpy to calculate the change in total internal energy. This diagram is widely used in mechanical engineering and HVAC technology and plots the Temperature versus the Absolute Humidity. With a Mollier Diagram (also know as Psychrometric Chart) you can draw processes of humid (moist) air and calculate air conditions.
