Thermodynamic methods for performance analysis of chillers

Abstract

This paper presents a simple thermodynamic model that captures accurately the behaviour of all types of real chillers or cooling devices. In addition to its predictive capability, it also provides a diagnostic means for the in situ monitoring of chiller performance. To enhance the understanding of the chiller cycles, a novel way of formulating the classic T-s diagrams is provided for all chiller types, ranging from the mechanical, heat-driven and solid-state chillers. © IMechE 2005.
