Equipment technology for refrigeration and air conditioning is an effort to understand the work and behavior of the components for the vapor compression refrigeration system. The book is present a clarification for the types, capacities, and limitations of the compressors that are used in vapor compression refrigeration system, also the types of the condensers and evaporators in addition to the kinds of throttling devices.The book extension to the other equipment which is work closed to the vapor compression refrigeration system like the cooling towers and types, also the air handling units with fan coil units. The books depend on the last published documentations which clarify the work and capacities from the famous professional companies.Part of this book is appropriated to the heating equipment specially fire tube boilers and electric boilers.The accessories and control devise take a good part of the book, and the manufacturing explanations are used to make the understanding easy and clear.We hope this book is new additional support to the students and engineering’s how work in this field of refrigeration and air conditioning.
