Vacuum systems are in wide spread use in the petrochemical plants, petroleum refineries and power generation plants. The existing texts on this subject are theoretical in nature and only deal with how the equipment functions when in good mechanical conditions, from the viewpoint of the equipment vendor. Also, the existing texts fail to consider the interaction of the vacuum system with the process equipment it serves and the variability of the motive steam conditions, change in cooling water temperature condenser fouling and erosion of the ejectors. Here are some of the many questions answered in this groundbreaking volume: Why does my first stage jet make a surging sound during hot weather? Why does the vacuum suddenly break? I've seen moisture condensing on the jet's body! What’s causing that? Why do I have to steam-out the drain legs from our condensers? Superheated steam is making our vacuum worse. Is this normal? How can I locate and measure air leaks? Reducing the steam pressure to my jets improves vacuum. But why? I can't pull the pre-condenser bundle. The shell side is fouling. What should I do? We're not getting our normal horsepower from our steam turbine. Could this be a jet problem? Raising the seal drum level improves vacuum! Is there an explanation for this? Our turbine exhaust steam pressure to our surface condenser has doubled in the last two years. What should we do? Restricting cooling water flow from our elevated condensers improves vacuum! Is this possible? What's a converging-diverging ejector all about? What's the difference between a barometric condenser and a surface condenser? Which is better?

Water (R718) Turbo Compressor and Ejector Refrigeration/Heat Pump Technology provides the latest information on efficiency improvements, a main topic in recent investigations of thermal energy machines, plants, and systems that include turbo compressors, ejectors, and refrigeration/heat pump systems. This, when coupled with environmental concerns, has led to the application of eco-friendly refrigerants and to a renewed interest in natural refrigerants. Within this context, readers will find valuable information that explores refrigeration and heat pump systems using natural refrigerants, polygeneration systems, the energy efficiency of thermal systems, the utilization of low temperature waste heat, and cleaner production. The book also examines the technical, economic, and environmental reasons of R718 refrigeration/heat pump systems and how they are competitive with traditional systems, serving as a valuable reference for engineers who work in the design and construction of thermal plants and systems, and those who wish to specialize in the use of R718 as a refrigerant in these systems. - Describes existing novel R718 turbo compressor and ejector refrigeration/heat pump systems and technologies - Provides procedures calculating and optimizing cycles, system components, and system structures - Estimates the performance characteristics of the thermal systems - Exposes the possibilities for wider applications of R718 systems in the field of refrigeration and heat pumps

Encompassing both practical applications and recent research developments, this book takes the reader from fundamental physics, through cutting-edge new designs of ejectors for refrigeration. The authors’ unique vision marries successful design, system optimization, and operation experience with insights on the application of cutting-edge Computational Fluid Dynamics (CFD) models. This robust treatment leads the way forward in developing improved ejector technologies. The book covers ejectors used for heat powered refrigeration and for expansion work recovery in compression refrigerators, with special emphasis on two-phase flows of “natural” fluids within the ejector, i.e. steam and carbon dioxide. It features worked examples, detailed research results, and analysis tools.
