Preface to Digital Control for Building HVAC Systems

Objective of This Guide The aim of this guide is to introduce and clarify direct digital management (DDC) techniques used for controlling air-con techniques in industrial and industrial buildings.

Having now been in widespread use for greater than a decade, DDC techniques will be present in just about each sort of constructing conceivable, managing environments from the important to the commonplace.

This textual content is a survey of DDC techniques from the attitude of the end-user and is meant to offer the reader with an understanding of the fundamental development of those techniques, in addition to their advantages and limitations.

Primary info on management techniques is supplied in Chapters 2 and 3, however the focus of this quantity is on the structure of DDC techniques and the way they’re greatest used to handle occupant consolation and power conservation.

Though written for building-industry professionals who’ve some understanding of the development of HV AC techniques, it’s my intent to current this info for the profit and understanding of anybody requiring information of nnc techniques.

It’s meant as a guide “for the remainder of us,” to borrow the acquainted slogan of Apple Pc, Inc.-the many who should specify, buy, handle, and assist microprocessor-based constructing management techniques and who could have solely a reasonable information of digital know-how and the way it works.

Within the chapters that observe we study fundamental management techniques and pc fundamentals; how the parts of those techniques are introduced collectively in distinctive methods to manage HVAC techniques.

The media used to attach these techniques to the gear they management and to their human hosts; the languages they use to speak between themselves and their human hosts; the applied sciences obtainable to translate communication between techniques of dissimilar manufacture.

Methods to make use of digital controls to handle constructing environments effectively; the way to cut back the primary value by cautious design and specification practices; strategies for precisely estimating the primary value; and what the way forward for DDC techniques could maintain.

An equally necessary goal of this guide is to offer readers with each a transparent understanding of the numerous enhancements these techniques supply over standard management strategies and the information wanted to make knowledgeable selections when approaching management system purposes.

In contrast to engineering textbooks, this guide is written from an utility perspective; how these techniques are used is given precedence over the underlying idea.

As such, once in a while phrases are used that some could contemplate proprietary, based mostly on my familiarity with sure merchandise and techniques. Nevertheless, each try has been made to explain {hardware}, software program, and system purposes in probably the most common phrases doable.

I’ve additionally averted using technical language or sophisticated formulation when explaining ideas and purposes. My hope is that the simpler this guide is to learn and perceive, the extra helpful it will likely be.

We start with a proof of what nnc is and the way it differs from conventional management strategies. If a number of the terminology is unfamiliar, do not be discouraged. Chapters 2 and 3 opinions the basics in preparation for extra detailed discussions in later chapters.
