This book provides a detailed analysis of absorption refrigeration systems, covering single effect to multi-effect systems and their applications. Both the first and second laws of thermodynamics are discussed in relation to refrigeration systems to show how system performance differs from one law to another. Comparative energy and exergy analyses and assessments of single effect, double effect, triple effect and quadruple effect absorption refrigeration system are performed to illustrate the impact of an increase in the number of effects on system performance. In particular, the second law (exergy) formulation for absorption refrigeration systems, rarely discussed by other works, is covered in detail.Integrated Absorption Refrigeration Systems will help researchers, students and instructors in the formulation of energy and exergy efficiency equations for absorption refrigeration systems.
