Heat integration refrigeration cycles

Refrigeration cycles offer many opportunities for heat integration with the process. These can be explored using the grand composite curve. 

From the magnetic entropy change it is easy to calculate the cooling capacity Q of the magnetic material, that is, the amount of heat that can be extracted from the cold end to the hot end of a refrigerator in one ideal thermodynamic cycle by integrating the following differential equation ... 

A particular feature of the Chart-flo is that it was developed at the outset for applications which could encompass reactions, as well as pure heat transfer duties, in its Chart-pak and other forms (see Chapter 5). As a heat exchanger reactor the scope of application becomes very wide, including continuous chemical reactions, fuel cells and other reforming applications. The compactness (see below) implies that it could be an integral part of many intensified processes, and a study of its implications for reducing the size of absorption cycle refrigeration plant has illustrated the benefits of multi-stream, multi-pass and multi-functional use within a single module.
