This comprehensive book has been developed to quickly train an average person for the vast commercial and residential refrigeration and air-conditioning market within a short period of time. It provides all the technical knowledge needed to start a successful refrigeration and air-conditioning business anywhere in the world.

This text provides background information, description, and analysis of four major cooling system technologies—vapor compression cooling, evaporative cooling, absorption cooling, and gas cooling. Vapor compression systems are currently the primary technology used in most standard domestic, commercial, and industrial cooling applications, as they have both performance and economic advantages over the other competing cooling systems. However, there are many other applications in which evaporative cooling, absorption cooling, or gas cooling technologies are a preferred choice. The main focus of the text is on the application of the thermal sciences to refrigeration and air conditioning systems. The goals are to familiarize the reader with cooling technology nomenclature, and provide insight into how refrigeration and air conditioning systems can be modeled and analyzed.Cooling systems are inherently complex, as the second law of thermodynamics does not allow thermal energy to be transferred directly from a lower temperature to a higher temperature, so the heat transfer is done indirectly through a thermodynamic cycle. Emphasis is placed on constructing idealized thermodynamic cycles to represent actual physical situations in cooling systems. The text also contains numerous practical examples to show how one can calculate the performance of cooling system components. By becoming familiar with the analyses presented in the examples, one can gain a feel for the the representative values of the various thermal and mechanical parameters that characterize cooling systems.

An easy-to-use tool for estimating heating, ventilating, and air conditioning systems, with up-to-date cost data and estimating examples. This all-in-one reference gives you the accepted standards and procedures for takeoff and pricing HVAC systems, as well as piping, plumbing, and fire protection. Includes all of the major mechanical systems in new building construction. The book will show you how to: Evaluate mechanical plans and specs so you can estimate all cost components Measure, quantify, and perform takeoffs for materials, labor, and equipment Identify and correctly apply direct and indirect costs, including overhead and profit Use forms to improve accuracy and efficiency – with electronic forms now available on the book’s own website Compare materials and methods and select the most cost-effective way to get the job done Train new estimators with clear instructions for estimating the mechanical trades Make the best use of RSMeans Mechanical Cost Data and RSMeans Plumbing Cost Data Organized for easy reference, the book gives you quick access to whatever aspect of mechanical estimating you need. It includes a glossary of mechanical terms and definitions – plus symbols used on mechanical plans, useful formulas, checklists, and conversion tables.
