Thermodynamics and Design Principles of Refrigeration Systems
Compressors , Psychrometry and Applications of Refrigeration and Air Conditioning have been included and updated for students to conceptualise the subject in a complete manner. The chapters consist of various exercises, examples, and multiple illustrations that aid in understanding the subject better. The subject of refrigeration and airconditioning is one of great significance as public focus shifts to food processing and preservation technologies. This highlights the need for professionals well-versed in the basics of this technology. A Textbook Of Refrigeration And Air Conditioning elaborates on the basics of this subject by including discussions on topics like multiple evaporator and compressor systems, simple and compound vapour compression refrigeration systems, air refrigeration cycles and systems, psychrometry, vapour absorption refrigeration and compressor systems, comfort conditions, psychrometry, refrigerants and compressors, cooling load estimation, steam jet refrigeration system, evaporators, condensers, expansion devices, and food preservation including cryogenics, fans, and ducts. A Textbook Of Refrigeration And Air Conditioning also features practical applications of refrigeration and air conditioning, thereby helping to buttress the theoretical knowledge already gleaned. The revised edition features colour pictures and refrigeration tables with charts, which help enhance the value of the content and assist students to bridge the gap between theory and practice.
HISTORY OF REFRIGERATION
The work of energy transfer is traditionally driven by mechanical means, but can also be driven by heat, magnetism , electricity , laser , or other means. Refrigeration has many applications, including household refrigerators , industrial freezers , cryogenics , and air conditioning. Heat pumps may use the heat output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to air conditioning units. Refrigeration has had a large impact on industry, lifestyle, agriculture, and settlement patterns. The idea of preserving food dates back to at least the ancient Roman and Chinese empires. However, mechanical refrigeration technology has rapidly evolved in the last century, from ice harvesting to temperature-controlled rail cars. The introduction of refrigerated rail cars contributed to the westward expansion of the United States, allowing settlement in areas that were not on main transport channels such as rivers, harbors, or valley trails.

This book has been written especially for use in programs where a full curriculum in refrigeration is offered. However, the material covered and the method of presentation are such that the text is also suitable for adult evening classes and for on-the-job training and self-instruction. Furthermore, the material is so arranged and sectionalized that this textbook is readily adaptable to any level of study and to any desired method or sequence of presentation.

A chiller is simply a device that is used to remove heat from something. For industrial purposes, chillers can be thought of as a component within a complex mechanical system that is used to remove heat from a process or substance. To really understand what a chiller is, a fundamental knowledge of the principles of basic refrigeration is required.
