Air Conditioning System Design

About this book

Air Conditioning System Design summarizes essential theory and then explains how the latest air conditioning technology operates. Load calculations, energy efficiency, and selection of technology are all explained in the context of air conditioning as a system, helping the reader fully consider the implications of design decisions.Whether users need to figure out how to apply their mechanical engineering degree to an air conditioning design task or simply want to find out more about air conditioning technology for a research project, this book provides a perfect guide.- Approaches air conditioning as a system, not just a collection of machines- Covers the essential theory on fluid flow and the latest in A/C technology in a very readable and easy-to-use style- Explains the significance of factors, such as climate and thermal comfort as A/C design considerations- Addresses design using a range of air conditioning technologies, such as evaporative cooling, VRF systems, psychromatic software, and dessicant dehumidification

Properties of Humid Air

Abstract

Air is the working fluid for air conditioning systems. It is therefore important for the engineer to have a thorough understanding of the properties of air, before going on to consider the processes that occur when air passes through the various plant items that make up systems. The word psychrometry is often used for the science that investigates the properties of humid air, and the chart that shows these properties graphically is known as the psychrometric chart.
