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

Begins with a general description of heat pumps and how they work, their terminology, and their standards. This is followed by details on air- and ground-source heat pumps, including their operation, components, energy efficiency considerations, sizing and design considerations, installation, benefits, maintenance, operating costs, and life expectancy. Heating energy costs are then compared for heat pump and electric heating systems at various locations in Canada. Related equipment such as supplementary heating systems, thermostats, and heat distribution systems is also reviewed. Finally, answers are provided to some commonly asked questions about heat pumps.

Amidst tightening requirements for eliminating CFC's, HCFC's, halons, and HFC's from use in air conditioning and heat pumps, the search began for replacements that are environmentally benign, non-flammable, and similar to the banned refrigerants in system-level behavior. Refrigerant mixtures are increasingly used as working fluids because they demo

The papers in this collection have originated from Britain, Eastern and Western Europe and India, with the delegates coming from fifteen countries, including a strong contingent from Japan. This indicates a widespread interest in the application of heat pumps. The heat pump suffers from an environmental dichotomy. On the one hand it saves fossil fuel energy, thereby reducing CO emissions. On the other hand, in the vapour compression form, 2 it generally employs CFCs which are destructive to our protective ozone layer as well as contributing to the greenhouse effect. Taking the first, heat pumps, perhaps have the widest application numerically in the heating (and cooling) of buildings and an excellent paper describes case studies concerning three large Norwegian hotels. In these, heat was pumped from the adjacent river or sea when heating was required, and during the summer, when cooling became necessary, to generate domestic hot water. The heat pumps were installed by SINTEF Refrigeration Engineering, Norway, and have demonstrated payback periods of about two years. The fractional total energy saving of the three hotels was 30% as a result, an impressive figure, indeed. A similar paper by a Belgian architectural consortium shows how this technique can be successfully applied to the cooling of a large television complex where considerable quantities of heat were being generated by the luminaries. In this exercise the cooling load was successfully pumped to provide hot water.

A practical guide to the majority of pumps and compressors used in engineering applications Pumps and compressors are ubiquitous in industry, used in manufacturing, processing and chemical plant, HVAC installations, aerospace propulsion systems, medical applications, and everywhere else where there is a need to pump liquids, or circulate or compress gasses. This well-illustrated handbook covers the basic function, performance, and applications for the most widely used pump and compressor types available on the market today. It explains how each device operates and includes the governing mathematics needed to calculate device performance such as flow rates and compression. Additionally, real-world issues such as cavitation, and priming are covered. Pumps & Compressors is divided into two sections, each of which offers a notation of variables and an introduction. The Pumps section covers piston pumps, radial turbopumps, axial turbopumps, rotating pumps, hydraulic pumps, and pumps with driving flow. The Compressors section covers piston compressors, rotating compressors, turbo compressors, ejectors, vacuum pumps, and compressors for cooling purposes. A virtual encyclopedia of all pumps and compressors that describes the mechanics of all devices and the theory, mathematics, and formulas governing their function Allows the reader to develop the skills needed to confidently select the appropriate pump or compressor type and specification for their applications Pumps & Compressors is an excellent text for courses on pumps and compressors, as well as a valuable reference for professional engineers and laymen seeking knowledge on the topic.

Industrial Gas Turbines: Performance and Operability explains important aspects of gas turbine performance such as performance deterioration, service life and engine emissions. Traditionally, gas turbine performance has been taught from a design perspective with insufficient attention paid to the operational issues of a specific site. Operators are not always sufficiently familiar with engine performance issues to resolve operational problems and optimise performance.Industrial Gas Turbines: Performance and Operability discusses the key factors determining the performance of compressors, turbines, combustion and engine controls. An accompanying engine simulator CD illustrates gas turbine performance from the perspective of the operator, building on the concepts discussed in the text. The simulator is effectively a virtual engine and can be subjected to operating conditions that would be dangerous and damaging to an engine in real-life conditions. It also deals with issues of engine deterioration, emissions and turbine life. The combined use of text and simulators is designed to allow the reader to better understand and optimise gas turbine operation. - Discusses the key factors in determining the perfomance of compressors, turbines, combustion and engine controls - Explains important aspects of gas and turbine perfomance such as service life and engine emissions - Accompanied by CD illustrating gas turbine performance, building on the concepts discussed in the text
