Refrigeration and Heat boosting general principles

The energetics section has two main headings, depending on the useful effect under consideration:

• power generation ;

• cold production or heat recovery.

In this second case, all the cycles used can be described as (as opposed to motor or direct cycles).

Here, we consider the general principles associated with reverse-cycle machines. The first approach described, which is very classical, uses the thermostatic.

We then show how to link the previous approaches to the thermokinetics, to build a genuine thermodynamics of reverse-cycle machines. The application of the above concepts is illustrated for the most common machine configurations.
