Overview
Most people think the air conditioning system's job is just to cool the spaces. Actually, a complete air-conditioning system is capable of maintaining temperature and humidity below or above that of surroundings and provides fresh air into spaces free of contaminants, dust and odorants.
Air-conditioning systems are bifurcated in two broad categories: comfort air conditioning and process air-conditioning. Comfort air conditioning refers to control of spaces to promote the comfort, health, or productivity of the inhabitants. Process air-conditioning systems are designed to facilitate the functioning of a production, manufacturing, or operational activity such as mission critical environments like datacenters, or medical facilities, which require year-round control of temperature, humidity and air cleanliness, within the narrow tolerances.
Commercial air-conditioning systems may contain a myriad of components, many of which are present in one form or other in a variety of configurations. Also these components may be assembled into systems literally a dozen or a hundred different ways but in practice these can be classified into three broad categories: all-air, all-water, and air-processed in a central air-handling apparatus. The boundaries between these system types are not absolute, but the choice largely depends on cost, aesthetics and degree of control.
This 8-hr course provides the common system arrangements of commercial air-conditioning systems and discusses the most prevalent system configurations, equipment and control strategies.
The student must take a multiple-choice quiz consisting of ten (10) questions at the end of this course to obtain PDH credits.
