This Manual was written to assist entry-level engineers in the design of air-conditioning systems. It is also usable - in conjunction with fundamental HVAC&R resource material - as a senior- or graduate-level text for a university course in HVAC system design. The manual was written to fill the gap between real world design practices and the theoretical knowledge acquired in the typical academic course or text book. Courses and text usually concentrate on theoretical calculations and analytical procedures or on the design of components. This manual focuses on applications.
