It has long been recognized that realizing the potential for energy conservation and diversification by using heat pumps offers considerable benefits to the environment. Important work on more efficient and ozone-friendly working fluids will further enhance the case for greater support of heat pump research. This book contains the Proceedings of the Third International Energy Agency Conference held in Tokyo in March 1990. The main theme of the Conference, 'Heat Pumps - Solving Energy and Environmental Challenges', is explained in great depth, covering not only technical characteristics but economic factors and the role of government and other bodies in promoting research, and the uses of all types of heat pumps are also fully considered. As well as publishing the papers presented at the meeting, the book also contains the extensive complementary poster sessions from the Conference.

Heat Conversion Systems develops the underlying concepts of advanced Rankine-based absorption and compression cycles and introduces the Building Block Approach as a general concept. The Building Block Approach identifies all cycle configurations for a given application to ensure that system designers have available all important alternatives. The book features numerous examples of advanced cycles and includes single- and multi-stage absorption heat pumps and heat transformers and combined systems. The book also discusses single- and multi-stage vapor compression systems with multiple solution circuits, multiple compressors, and cascades. Aspects of working fluid selection and their influence on cycle options, performance evaluation, and estimating procedures for the Coefficient of Performance (COP) are addressed. Cycle analysis based on the Second Laws of Thermodynamics is examined. Heat Conversion Systems will be an important source for engineers in air-conditioning, heat pumping, refrigeration, and waste heat utilization. It can be used as text in courses on thermodynamics, efficient use of energy, and environmental protection.

The 70 papers collected in this volume present an up to date review of the trends in heat pump technology. The heat pump is reviewed both as being part of a more comprehensive system, and as a refined device providing energy and greenhouse gas emission reductions. Its implementation in a system or process must be carefully considered at an early stage of design or development, and process integration is discussed in detail as a valuable tool for industry. The heat pump is proving to be a highly effective energy conserving tool, particularly when designed and used as an integral part of a system. Environmental benefits are gained when energy is conserved, and heat pumps can make a major contribution in this area. However, some heat pumps use working fluids which are environmentally unfriendly, and the progress that has been made in the field of alternative refrigerants is reported on. The volume will prove an indispensable reference source on the wide-ranging applications that have been developed since the last international conference, on such topics as heat pump field trials, pilot plants and development programmes.
