The absoption refrigerator as a thermal transformer

TL;DR

This paper conceptualizes the absorption refrigerator as a thermal transformer, drawing an analogy to electric transformers by relating entropy and electric charge as extensive variables, and temperature and electric potential as intensive variables.

Contribution

It introduces a novel analogy between absorption refrigerators and electric transformers based on thermodynamic and electrical variable correspondences.

Findings

Establishes a formal analogy between thermal and electrical transformers.

Highlights the correspondence between entropy and electric charge.

Links temperature and electric potential as analogous variables.

Abstract

The absorption refrigerator can be considered a thermal transformer, i.e. a device that is analogous to the electric transformer. The analogy is based on a correspondence between the extensive quantities entropy and electric charge and that of the intensive variables temperature and electric potential.
