HVAC Engineering Fundamentals: Part 1

Source: hvac Systems Design Handbook Chapter hvac Engineering fundamentals : 1. part 1. Introduction This chapter is devoted to fundamental'' fundamentals certain prin- ciples which lay the foundation for what is to come. Starting with the original author's suggested thought process for analyzing typical prob- lems, the reader is then exposed to a buzzword of our time: value Engineering . Next follows a discussion of codes and regulations, polit- ical criteria which constrain potential design solutions to the bounds of public health and welfare, and sometimes to special interest group sponsored legislation. The nal sections of the chapter offer a brief review of the basic physics of heating, ventilating, and air conditioning ( hvac ) design in discussions of uid mechanics, thermodynamics, heat transfer, and psychrometrics. Numerous classroom and design of ce experiences remind us of the value of continuous awareness of the physics of hvac processes in the conduct of design work. Problem Solving Every hvac design involves, as a rst step, a problem-solving pro- cess, usually with the objective of determining the most appropriate type of hvac system for a speci c application.
