Review of materials for energy saving technology

During the last 20 years, interest in the closed adsorption heat pump and refrigeration systems has increased steadily. In this paper, consideration is given to aspects of adsorption refrigeration in terms of existing materials used in adsorption refrigeration, heat transfer characteristics of materials, and cost of materials and manufacturing. The heat and mass transfer play very important roles in improving the cycle performances and their optimization is one of the technological challenges in developing adsorptionrefrigeration systems. In order to optimize an adsorber it is essential to control unconsolidated adsorbers; coated adsorbers and consolidated adsorbers. The paper is a general review of adsorption refrigeration technology and provides information of value to those involved with heat pump and refrigeration systems technology.
