Description :

This book, viz. “Applied Thermodynamics: Software solutions – Vapor compression refrigeration cycles” is a supplement to the Part-III of the popular, free ebook series on Applied Thermodynamics: Software Solutions by the same author, published by Bookboon.
In this book, as with other books of this series, the focus is on the solutions of problems using computer software. Only the essential theory and summary of equations required for calculations are given at the beginning of the chapter.
Here, we have particularly focused on solving problems with the very useful software, Mathcad. Since Mathcad does not have built-in functions to determine the properties of refrigerants, we have first written useful functions for properties of refrigerants such as R134a, R12, R22 and Ammonia (NH3) using data from NIST. Then, we demonstrate the ease with which one can do calculations, produce tables and graphs of results, and perform ‘what – if analysis’ with Mathcad, by solving a variety of problems.
Several Functions are written in Mathcad to simplify the standard and most required calculations, which, the students, teachers and researchers may find very useful.
