air conditioning system design manual second edition pdf
The user/reader should be familiar with the general concepts of HVAC&R equipment and possess or have access to the four-volume ASHRAE Handbook series and appropriate ASHRAE special publications to obtain grounding in the fundamentals of HVAC&R system design. Information contained in the Handbooks and in special publications is referenced—but not generally repeated—herein. Inaddition to specific references cited throughout the manual, a list of general references (essentially a bibliography) is presented at the end of this chapter.
The most difficult task in any design problem is how to begin. The entry-level professional does not have experience from similar projects to fall back on and is frequently at a loss as to where to
start a design. To assist the reader in this task, a step-by-step
sequence of design procedures is outlined for a number of systems.
Simple rules are given, where applicable, to assist the new designerin making decisions regarding equipment types and size.Chapter 2 addresses the difference between analysis and design. The chapter covers the basic issues that are addressed during the design phases of a building project and discusses a number of factors that influence building design, such as codes and economic considerations.
Human comfort and indoor air quality, and their implications for HVAC&R systems design, are discussed in Chapter 3. Load calculations are reviewed in Chapter 4. The specifics of load calculation methodologies are not presented since they are thoroughly covered in numerous resources and are typically conducted via computer programs. HVAC&R system components and their influence on system design are discussed in Chapter 5.
