Properties of Refrigerants: Interpolation

May 19th, 2026

When looking up information in a saturated or superheated table, sometimes the reference value falls between two rows in the table. When this occurs, engineers must either approximate the value or interpolate between two available rows. In thermodynamics, interpolation is a way to “fill in holes” in tables. For example, in this saturated table, the thermodynamic […]

Properties of Refrigerants: Entropy

May 12th, 2026

“Entropy” can be a difficult concept to understand. In the context of thermodynamics, entropy can be thought of as a measure of “disorder”. The second law of thermodynamics teaches that entropy always increases over time.  In the refrigeration cycle, entropy is used to determine the theoretical discharge temperature. The term “theoretical” is applied because we assume […]

Properties of Refrigerants: Halocarbon Refrigerants

May 5th, 2026

Halocarbons are man-made compounds. The term halocarbon is shorthand for “halogenated hydrocarbon”. A halocarbon is a hydrocarbon compound that has replaced at least one hydrogen atom with a halogen atom.  Halocarbons have been used for many purposes, such as Solvents, Fire Suppression, and Refrigeration. Halocarbons boil at various temperatures. Based on the chemical formula, each […]
