This Instructors’ Manual complements Air
Conditioning, A Practical Introduction, third
edition, with a bank of multiple choice answer
questions. 1300 questions cover the range of
topics in the textbook and more. The objective

Introduction
Air Conditioning, A Practical Introduction, third edition, Instructors’ Manual complements
the textbook with a bank of multiple choice answer questions. Questions cover the range of
topics in the text book and more. The objective of this manual is to provide a teaching,
learning and testing resource that the author never had, but would have appreciated.
The comprehensive contents list is hyperlinked to all chapters and subject sections to make
navigation and return to the table of contents easy.
The subjects within this manual can be of valuable assistance to instructors of courses
other than within those of building services engineering, architecture, surveying and
construction.
Wherever air conditioning systems, climate variation, low energy uncooled buildings,
cooling load calculation, annual energy, psychrometrics, fan applications, air duct design,
building management systems (BMS), commissioning, maintenance, air duct acoustics, post
occupancy assessment, thermal environment, human comfort, energy economics, ventilation,
assessing a project cost and selling price and the use of units of measurement are studied,
users will find material of benefit.
Instructors can easily edit and adapt the questions provided for their own purposes and
create unique testing assignments.
There are over 1300 questions . These repeat questions in the printed book and add many
multiple choice answer questions. They are collected into subject groups and also into random
subject sections.
Correct responses are in red as the Instructors’ Manual is only provided as downloadable
files to instructors. The user edits the highlighted answers when preparing them for student
use. Question grouping allows rapid access to each topic area. Some questions require more
Page 2 of 441
knowledge than is provided in the printed book. Users need to draw upon on-site observation
and experience plus further investigation, discussion, questioning and searching the internet.
Multiple choice questions usually have responses with only one correct answer, although
discussion may occur where shades of opinion are not clear-cut for every application. In order
to stimulate users away from only seeking one answer, many questions are provided with
more than one correct response.
Correct answers are only one part of the whole solution; just select from answers provided.
Use these questions for class and individual revision. Even the spurious alternatives
provide a valid means of revising understanding and reinforcement of learning. They all
require mental gymnastics to evaluate them. Groups of questions can be provided to students
for assignments. Test students’ understanding by requiring explanations for why answers are
incorrect.
The author has found that students respond well to competition between groups when led
by the instructor as it adds an element of fun to learning. A class quiz of twenty-five questions
is about right for a one hour session for groups of up to five students each. The quiz leader
fires a question at a named individual, allows no conferring within the group, awarding one
point for the correct response and taking a point away from the group if incorrect, then throws
the question open to anyone to answer for a point.
Alternatively, display a question with optional responses though a data projector for the
class from the files provided. Correct solutions appear on a second slide highlighted in red.
The instructor challenges a group to discuss and agree the correct responses within say thirty
seconds, awarding a point for fully accurate answers.
Sets of questions are suitable for college internal websites where students are allowed
limited time for undertaking tests and assignments. Files of questions may be emailed to
students for response by a specified date and time.

Some of these multiple choice questions are reproduced in the printed book to stimulate
interest and prepare readers for tests; they appear in the questions bank and in each chapter.
Such duplication from the manual does not create conflict as the textbook and the manual
have different readerships. The instructor is provided with all the available questions in this
manual.
The author expects users to find as much enjoyment and educational benefit in answering
and discussing these questions as he did in producing them. Happy quizzing!
