HVAC Instant Answers
HVAC Instant Answers is meant to provide both theoretical background and principles of operation of equipment, while at the same time giving the reader a practical means for quickly solving problems. The basic philosophy of this guidebook is to work backwards from the effects of a problem, hopefully eliminating many false leads along the way. We have tried to reach a compromise between solutions that are too simplistic or too complicated. It is emphasized that more often than not the cause of a control or equipment problem may not be in the obvious place. The key point is to identify what is causing the building occupants to express concern.

This book is aimed at the field technician who has the of task solving problems rapidly and efficiently. It is the unfortunate truth that most facility management teams are understaffed. The technicians spend a lot of time satisfying occupant comfort complaints and often do not have the time to spend tracking down the root of many problems.

Every building is different. Even those that appear similar from the outside will certainly have differences in their structure, their use, and the quirks of their behaviors. Like people, no two are alike. In fact, the idea of a building as a person has some merit: most buildings have a need to take in fresh air and expel contaminated air. Many buildings provide a constant circulation of fluids around the building, and practically all buildings must maintain an internal temperature set point for the comfort of the occupants. We even now refer to problems as if we were describing people: a structure may have sick building syndrome. Some buildings are naturally relaxing to the occupants, others are disconcerting for one reason or another.
