Fluid pairs for advanced absorption cycles: selection methods and data requirements

This paper presents a review of selection methods for new absorption heat pump fluids, including a comprehensive set of fluid characteristics for screening candidate fluids. These characteristics include thermal and physical properties, transport properties, chemical characteristics, design and economic considerations. Also presented is a worldwide review of the new fluids and advanced cycles currently being researched. Based on these reviews, an assessment is made of the fluid property data requirements and costs needed to support advanced absorption system research and the implications for research managers.
