Thermodynamics tutorial heat pump and refrigeration

Refrigeration is the process of removing heat from an enclosed space, or from a substance, and rejecting it elsewhere for the primary purpose of lowering the temperature of the enclosed space or substance and then maintaining that lower temperature. The term cooling refers generally to any natural or artificial process by which heat is dissipated. The process of artificially producing extreme cold temperatures is referred to as cryogenics.

Thermodynamic Analysis of Compressed Air Vehicle Propulsion

by : European Fuel Cell Forum

The fist compressed air vehicles were built by Andraud and Tessié du Motay in
Paris between 1838 and 1840. Since then the idea has been tried again and
again, but has never reached commercialization. In recent years the French
developer MDI has demonstrated advanced compressed air vehicles. However,
the claimed performance has been questioned by car manufacturers and
automobile expert. Basically, when referred to ambient conditions, the relatively
low energy content of the compressed air in a tank of acceptable volume is
claimed to be insufficient to move even small cars over meaningful distances

On the other hand, another air car developer claims to have driven 184 km on
one 300 Liter filled with air at initially 300 bar pressure. Obviously, there are
issues to be resolved, not by heated debates, but by an analysis of the
thermodynamic processes involved. This is the aim of this study

Selected Values of Chemical Thermodynamic Properties

Prepared by David R. Lide.
Introduction
The theoretical framework of thermodynamics was well established by the time NBS was founded, and certain important applications, such as improving the efficiency of steam engines, had been demonstrated. However, the broad application of hermodynamics to the design and control of industrial processes had to await the accumulation and organization of a large amount of experimental data, as well as theoretical contributions from quantum mechanics and statistical mechanics. The appearance of Selected Values of Chemical Thermodynamic Properties [1] in 1952 marked a significant milestone in this process. This book represented the culmination of 20 years of work
by Frederick D. Rossini and coworkers in evaluating and systematizing the data that had appeared in the world literature on thermochemistry.
