Foreword
Plate heat exchanger and plate heat exchanger device is essential to the process of industrial heat transfer equipment, including power almost used, chemical, metallurgy, food, light and all industrial sectors; the same time, it is also air-conditioning, heating in important part; in the Secretary's policy of sustainable development, it is waste heat utilization, solar energy use, water use, water use, geothermal utilization of key equipment. As technology advances, as well as resource and energy conservation urgency in recent years developed a series of new plate heat exchanger, such as removable, all welded, brazed, plate-shell, etc., and from the plate development to the plate heat exchanger device, such as evaporators, heat pump, refrigeration equipment, heat unit, catalytic reforming unit, gas condensate recovery and so on. Increasingly wide scope of application, requirements for growing, production is also increasing. But there is no more perfect a new type of plate heat exchanger, and a new plate heat exchanger device structure, principle, character, layout, selection, installation and operation of such technology and application manual. In order to meet market demand, in order to industrial, air conditioning, heating, new energy use and waste heat utilization of the design, application, construction and operating personnel to provide relevant data and information, in order to heat engineering professionals providing educational materials, set up by the plate for heat experts, members of the Standards Committee plate heat exchangers, manufacturing experts, patent inventors, design and construction of the Editorial Committee composed of staff and users.
This book is the principle of editorial writing applications for each user, design, construction, operation provide a technology and application manual. Since it is a tool, the content must be complete, concise, and concise and practical. Both full and simple, is consistent with science, and technology to meet the practical application of the manual to really play a pioneering vision to simplify the design calculations, improve efficiency, facilitate the practical application of the role as related to various fields and heat transfer engineering and technical personnel of the right-hand man and reliable tool.
This book is divided into two technical papers and application papers, a total of 15 chapters. The first chapter describes the contents of the main heat exchanger and plate heat exchanger plate device of basic theory, performance, design methods, performance, testing and operation and maintenance, but also describes the plate heat exchanger of the status and trends. Second primary role is to industry, air conditioning, heating, new energy and other areas of the users, design, construction and operation personnel and the plate heat exchanger plate heat exchanger application of principles and methods of installation. At the same time in the form of examples, concise account of the way the application of design methods and energy saving, economic and environmental benefits. Readable, wide applicability. To make the book more systematic, broader range of applications, the editorial board during the preparation process, in addition to extensive collection of examples of domestic, but also build a number of foreign papers, such as plate heat exchanger in Industry ; have chosen to introduce a number of foreign new technology, new materials and new methods, such as plate heat exchanger and plate heat exchangers for the gas thermoelectric Cooling System and so on.
In the preparation process, we also get a lot of enthusiasm to encourage peers and specific help, provide us with many of his comrades research results and information available. At this point, would like to extend these peers and of sincere gratitude.
China Building Industry Press Yao Ronghua, deputy editorial, from the identification until the final review of the final preparation of the outline, start to finish to give a great deal of care and support for the publication of the book their hard work, also like to thank here.
As writers is limited, the error is inevitable, the wing sincerely welcome readers to the second edition to be corrected.
