What are the thermodynamic properties of refrigerants?
Table of Contents
Temperature, pressure, density (Specific volume), and enthalpy are the main properties of the refrigerant which are considered for this analysis and the graph is plotted by taking the temperature on the x-axis and other properties on the y-axis.
What temperature does R134a boil at?
-15.34°F (-26.3°C)1,1,1,2-Tetrafluoroethane / Boiling point

What is r314a refrigerant?
1,1,1,2-Tetrafluoroethane – R-134a – is an inert gas used primarily as a high-temperature refrigerant for domestic refrigeration and automobile air conditioners. Sponsored Links.
How are thermodynamic properties classified?
Thermodynamic properties are divided into two broad types: intensive properties and extensive properties. An extensive property is any property that depends on the size (or extent) of the system under consideration. Volume is an example.
What is the chemical formula for tetrafluoroethane?
CH2FCF31,1,1,2-Tetrafluoroethane / Formula
What makes R134a a good refrigerant?
R134a has fairly good dielectric properties as it has high thermal stability, low boiling point, and chemical inertness against the construction materials used; and is non-toxic and non-flammable. . A dielectric substance in its gaseous state can be used to prevent electric discharges.
Is R134a an HFC?
HFC Refrigerant: HFC refers to the chemical composition of the refrigerant. Hydrofluorocarbon indicates that the refrigerant is comprised of Hydrogen, Fluorine, and Carbon. Common HFC refrigerants are R-32, R- 125, R134a, R-143a, and R-152a. A blend that contains different HFCs is considered an HFC refrigerant.
Can R22 replace R134a?
However, units made after 2010 can use R22 alternatives such as R410A, R134A, R407C, and R407A. These refrigerants cool just as effectively as R22 without the ozone depleting features, and they have an acceptable Global Warming Potential (GWP).
What are types of thermodynamic property?
There are 8 (eight) properties describing the behavior of a system. They are pressure, temperature, volume, entropy, internal energy, enthalpy, Gibbs function and Helmholtz functions.
