HVAC Engineering Fundamentals: Part 1

1 Chapter1 hvac Engineering Fundamentals: part IntroductionThis chapter is devoted to fundamental fundamentals certain prin-ciples which lay the foundation for what is to come. Starting with theoriginal author s suggested thought process for analyzing typical prob-lems, the reader is then exposed to a buzzword of our follows a discussion of codes and regulations, polit-ical criteria which constrain potential design solutions to the boundsof public health and welfare, and sometimes to special interest groupsponsored legislation. The final sections of the chapter offer a briefreview of the basic physics of heating, ventilating, and air conditioning( hvac ) design in discussions of fluid mechanics, thermodynamics,heat transfer, and psychrometrics. Numerous classroom and designoffice experiences remind us of the value of continuous awareness ofthe physics of hvac processes in the conduct of design Problem SolvingEvery hvac design involves, as a first step, a problem-solving pro-cess, usually with the objective of determining the most appropriatetype of hvac system for a specific application.

If value engineering seems to share some common analytical tech-nique with Sec. 1.2 on problem solving, the dual presentation is in-tentional. Both discussions are approaches to solving problems, to im-proving service. The first is an interpretation of a mentor’s example, HVAC Engineering Fundamentals: Part 1
