Résumé

A multiple circuit shell and tube heat exchanger exchanges heat between a heat transfer fluid and refrigerant. The first portion of the heat transfer fluid flow enters a first refrigerant circuit and exchanges heat with refrigerant in the first circuit. The second portion of the heat transfer fluid flow then enters a second refrigerant circuit and exchanges heat with refrigerant in the second circuit. By employing a single heat transfer fluid pass, the average leaving temperature difference from each circuit can be reduced, reducing entropy generation and making the system more thermodynamically efficient.
