This book provides an in-depth description of absorption chillers and heat pumps, focusing on relatively simple systems that employ working fluids in the liquid and vapor phases. Along with solid thermodynamics background material, this treatment includes extensive examples and a demonstration copy of the Engineering Equation Solver (EES) program and program files for all of the examples in the text. The student or engineer who is a newcomer to the field will gain a comprehensive knowledge essential for the design and evaluation of absorption systems.
